Title: Poll - Scent Dogs Accuracy
Post by: debunker on April 28, 2013, 12:52:28 PM
Additionally for the true possible marking of Cadaver scent, as this involves two reactions rather than one, the accuracy is 9/10 squared or about 8 out of ten- one suggestion in five will be an error.

I don't believe you can put a figure on the accuracy as there are to many external factors which have to be taken into account.  If you gave every dog the same test then compared the results then I would accept the findings but sporadic results combined are worthless.

If every peer reviewed test of dogs showed a maximunm accuracy of about 90% then it is quite valid to assume that no dog is an outlier with accuracy over a long p[eriod any better than the average unless the are specifically tetsed. That is how science works.

There is no evidence that Eddie is better than any other dog- in fact there is no reliable unbiased evidence at all available about Eddie's accuracy

You misunderstand debate and the scientific method.

No-one hags so far produced a peer reviewed experiment where scent dogs have a greater than 90% accuracy in real life situations. It seems to be the best available estimate- some being as low as 35% and a few as high as 90%.

My views are immaterial- anyone else is welcome to provide a reference for any published experiment with better proof of accuracy.

That is how science and forensics works.

There is no statistical analysis giving any form of confidence intervals. This is probably because the small scale of the experiment would have produce confidence intervals which were indicative of the experiment not being well designed enough to draw any scientific conclusion.

That said, even in this non in vivo experiment, the accuracies are usually lower than 100%.

THis piece of research needs to be interpreted against contrary evidence from well designed experiments with full statistical analysis.

WE have here an poorly designed and badly interpreted experiment which produces results outside the envelope for well desig need and interpreted experiments.

Properly designed and well analysed experiments have what are call confidence intervals associated with them. These give a rating for how much an experimental results are a better prediction than mere chance. The more individual tests there are, the higher the confidence interval will be.
 
When no confidence interval is stated, it is a sign that there is likely to be a problem with that issue- usually caused by too few individual tests.

For instance if we do a coin toss experiment (which should be 50/50 with a fair coin) initial results with less than a hundred tests are likely to deviate from this 50/50 result, but experiments with hundreds of tests will tend to return to the expected mean.

Low test number experiments do not allow valid conclusions.

Most research has been done on a variety of scent dogs because cadaver dogs are a more recent development, and because there is no reason to assume any difference between different target sniffer dogs.

Any research on cadaver dogs tends to be small scale, badly designed and often done outside peer review and by people with a particular expectation of results.

The paper you quote is probably the best (of a bad job lot) on cadaver odor detection.

Well designed and interpreted experiments on scent dogs vary from 0% (Where no target scent was used, but handlers "knew" which objects were "contaminated", through 35% for in vivo drug detection dogs, to a maximum of 90%.

I use tbe90% figure to be as fair as possible to dog worshippers. My best guess is that dogs are rarely better than 80% accurate.

What about all the times the dogs failed to detect anything when there was in fact something to find?  Are these episodes classified as fools errands or are they conveniently overlooked?   Let's face it a spaniel's hooter and what it can achieve is not an accurate science and more akin to a circus act.

Those who promote this ability or whatever it is called do so in order to embelish their own credibility and line their pockets.  How many of these dogs are winging their way to Bangladesh to do their bit?

It is not an accurate *science* but neither is it a clown act, if it were, law enforcement throughout the world would not waste time energy and money on a *clown act*

PS I also wondered why these dogs were not sent to Bangladesh......answers on a postcard and it isnt because dogs are clown acts

Eddie was tested constantly by Grimes using a jar filled with some old decayed relic with its own distinctive odour so what's to say this is what Eddie tried to find every time he went out to play?  What are the chances that this same odour is left behind by a fresh corpse?

Nobody is saying it is a clown act redblossom.  It is a game to these dogs which us humans have tried to harness to our own advantage.  Sometimes it works but more than often they find nothing.  My point is that when they find nothing how do we know that is a false positive rather than a true negative ?? 8)-)))

No one disputes that. The problem here is, as I see it, is that the dogs have alerted in an extraordinarily high ratio to places connected to the Mccanns vis a vis other places

And I do not accept Mr Grime was cueing them to do so.

Angelo, how do you know Eddie was teated *constantly* with this method and no other? The odour is no different from an old or new body.Mr Grime says the dog picks it up shortly after death to skeletised condition.

The only way you can assess the difference between false positives and true negatives is when a case is solved as I understand it. That indeed, a missing person had died and the  dog picked up the scent in the last place they were seen where a body had been but removed.

The thing you have to remember to is that different dogs trained on cadaver residue will react to different odours. Some are trained on real corpses in America while British dogs might have been trained on others forms of dead cellular human material.  Point I am making is that one dog might react to something while another dog won't do so.  I would love to see this put to test some day and then we would know just how good or bad these canines are.

What is not made clear is the difference in odor between Pork prepared for food which is carefully treated to avoid offensive odors and pig flesh and other naturally decaying animal residue.

Food is usually kept well away from the intestines as soon as slaughter occurs and this reduces residual odors. It is quickly cleaned of all bacteria, drained of blood and chilled to keep it fit for consumption.

When Mr Grime declares that Eddie has not reacted to foodstuffs in 200 cases, this not exclude the possibility that if he came across dead animal residue, then he might well react to that.

Yet Mr. Grime said Eddie had reacted to pork that had been burnt.

It is all these things that Eddie will react to that confuses me.     Things that are 100's of years old etc.

Also the clothes that Eddie alerted to.    A small t.shirt??    nothing of Gerry's??   

Then there's Cuddle Cat Eddie played with it and didn't react,  then reacted when it was put in the cupboard.

that Eddie and Keela dined on salmon (unlike their poor PT canine colleagues)
were insured for quasillions
earned as much per day (FOR THEIR HANDLER) as a Chief Constable in England

That was pure hyperbole - we, the great unwashed were being primed very early on to accept anything that

Devilsadvocate, of course, if you think he makes it up as he goes along, thats your prerogative, would seem a pretty poor strategy to me if he were out to deceive or exaggerate

It would call into question the Law Enforcement Agencies who routuinely paid Mr Grime and his dogs £I,000 a day plus expenses out of public money

I guess the professionals must have been considerably more impressed with his results than some of the self proclaimed experts here

ditto

The only thing that might convince me that the cadaver dog alerts in 5a had nothing to do with Madeleines disappearance was a post by Angelo IIRC ie that that flat had dozens of people going through it, unlike all the other places and one of them could have transferred this scent...a common sense possibility is worth far more than the constant trashing of the dogs mr grime mr amaral and others and bleats like eddie alerted to a coconut, which is the most pathetic thing ever uttered for obvious reasons such as eddie does not alert to coconut and also the so called coconut shell had collagen in it which only exists in mammals

Then again does scent transference last as much as original scent?  Questions questions


Anyone debasing dog handlers doing a job to help find criminals and get closure for families should have a look in the mirror and realise what they are saying when they are accusing them of fraud

I hope all the accusers and  debasers of dogs abilities ans their handlers  never have to have them used

What about all the times the dogs failed to detect anything when there was in fact something to find?  Are these episodes classified as fools errands or are they conveniently overlooked?   Let's face it a spaniel's hooter and what it can achieve is not an accurate science and more akin to a circus act.

Those who promote this ability or whatever it is called do so in order to embelish their own credibility and line their pockets.  How many of these dogs are winging their way to Bangladesh to do their bit?

If there were rich pickings to be had like in Luz or Jersey - the departure halls would be filled to capacity with
wonderdogs - alas this is probably one of the poorest countries in the world - so no big bucks to be made

Keela reacted to the key fob- 90% chance of the alert being correct and so identifying blood.

Gerry McCann's DNA found by LCNDNA analysis.

The human detritus found in the back of the car may or may not have been blood. 90% chance again. What was recovered was too small a sample to be identified as a particular fluid or solid.

You have a choice:

You can hold that a reaction from Keela means that there is blood there

Or you can maintain that there was no blood in the car despite Keela's reaction.

Me, I'll stick with the facts. Blood with a 90% probability.

How can me saying that Keela is 90% accurate be changed in your mind to saying that blood was definitely there. Do you not understand probabilities?

You cannot have it both ways, which is what you are trying to do.

DB you misinderstood what I was asking, try again, I was not arguing about blood, keela or the places it was found

These quotes from the FSS report are to do with the material found behind the sofa in the case of Madeleines DNA mentioned and the material found on the key card of the car mentioning Gerry Mccann's DNA

Both relate to blood presumably as they were taken from where the blood dog alerted, but anyway

My point was that you and others talk about Gerrys blood being found as a fact but simutaneously saying Madeleine's was not found. So the question is how can you say that based on the report? What is the difference between the two quotes?

--------
One
An incomplete DNA result was obtained from cellular material on the swab (286A/2007 CRL 3a). The swab contained very little information and showed low level indications of DNA from more than one person. However, all of the confirmed DNA components within this result match the corresponding components in the DNA profile of Madeline McCann. LCN DNA profiling is highly sensitive; it is not possible attribute this DNA profile to a particular body fluid.

Two
A low level incomplete DNA profile which matched the corresponding components in the DNA profile of Gerald McCann was obtained from cellular material on the key card (286C/2007-CRL(12)). This sample has not been sent for further testing using LCN DNA profiling tests.

One was a sample from a single person and all of the markers were identified as Gerry.

The other was a random agglomeration of three to five different people's DNA which did not allow any information about which marker came from which of the 3-5 people, thus making it possible that ANY such selection of 3-5 people's DNA would include many of Madeleine's markers. Then you factor in that the contributors could include Kate and Gerry who between them share all of Madeleine's markers, and Amelia and Sean who share 25% each of Madeleine's marker. The sample is necessarily without any probative value.

How were all the markers identified as Gerrys if it was an incomplete dna profile?

re swab 3a this is NOT the sample from the car that was from 3-5 people, it was a swab from the living room, granted it said from more than one person, my point was how do you say corresponding and confirmed markers match in one case must mean one thing,  and corresponding and confirmed markers just cannot mean another

Your answer is here



http://www.mccannfiles.com/id268.html




An incomplete DNA result was obtained through LCN from cellular material present in the swab (286A/2007 CRL 3A). The low-level DNA result showed very meagre information indicating more than one person. Departing from the principle that all confirmed DNA components within the scope of this result originated from a single source, then these pointed to corresponding components in the profile of Madeleine McCann; however, if the DNA within the scope of this result originated from more than one person then the result could be explained as being DNA originating from Kate Healy and Gerald McCann, for example. DNA profiles established through LCN are extremely sensitive; it is not possible to attribute this DNA profile to a particular body fluid. nor to determine how or when that DNA was transferred to that area.

Whats the difference between an incomplete dna result and an incomplete dna profile vis a vis those two specific examples

It is quite clear. One is possibly mixed but has few non-target markers. Given that we know that someone with those markers was in the room and there are most of their markers present it becomes likely that the target was the source.

Both 3a and 3b are specific enough for them to be said to be probably from the target.

One of the things I found interesting re. the April Jones case,  is the blood in the grout of the tiles.

I have often wondered,  if Madeleine had fallen and bled behind the sofa,   why Keela didn't alert to a larger area of the tiles as the grout would have soaked up the blood surely?

I find anything that goes onto the grout of tiles is different to clean off.    How would blood of Madeleines get under the tiles and not be in the grout?

There is confusion over what exactly a 'cadaver dog' is. They are called by Grime Enhanced Victim Recovery Dogs (EVRD). VRD are dogs that can smell either/or decayed flesh or blood- all you need when looking for victims. EVRD's are further trained to discriminate decaying flesh and blood dogs just decaying blood (neither react to fresh blood).

It is Grime's claim (not respected by all Dog Handlers and scientists) that dogs like Eddie and Morse can not only find bodoes and victims, but can also indicate non-physical presence (odor alone) of decay.

Not much of this has been tested in any peer reviewed journal in large enough experiments to tell us what is going on.

I'm obviously new to this forum and am aware that this is an older thread, but I would just like to say that having read through it I found it very informative, and it confirmed my skepticism of sniffer dogs' accuracy in general; so thank you, Debunker, and other contributors for compiling the research.

My friend has been training dogs since 1974, not to just sniff stuff out, but for films and advertisements too.

I asked her about the accuracy of the sniffer dogs, and she told me she would say if they indicate then it is more likely 100 percent accurate. They go for rigorous training, and if they fail once they are never used again.

I will say this i have a jack russell from a pup. She started to want to lick my left leg and foot it was quite bizarre. A few weeks afterwards I lost the use in my left leg, and eventually after lots of tests was diagnosed with MS....weird.

Also dogs are used in sniffing out cancers very successfully too and are even trained to alert someone who is going into diabetic coma etc. Some diabetics actually have these dogs now to alert them. Dogs help blind people live a good life, they use their keen sight and keen nose to keep these people safe.

They find bodies buried and can sniff out drugs and explosives.

Eddie and Keela were used not far from where i live. They picked up scent of death behind a sofa and blood. The guys wife had gone missing he swore she had run off. Anyway even without a body he was found guilty of her murder.

Eventually he did confess and said he had a row with his wife and struck her hard then strangled her, and he put her behind the sofa until the evening so he could move her. He lived on a big farm lots of acreage. He simply dug a huge hole with digger and put her in an empty large drainage pipe and buried her.....Cadavar dogs had been used in the area, but with the body in the pipe they never got wind of her scent.

I think the dogs are very accurate otherwise one mistake they have gone anyway to be used for other things.

Just because they indicated death and blood in apartment 5A it doesnt mean it was Maddy it could have been from somewhere else a transference or even perhaps brought in by someone..who knows. They cant say who died or who bled just that someone did.

If you are talking about Adrian, he murdered her in the shooting lodge and wrapped her in the curtains there before putting her in the back of his Land Rover.  She was never in the house after being killed was she?  Just checking.

The scenarios you cite are not comparable because your examples are simple to check
 
1  A plane can be searched -. Either there is a bomb on the plane or there isn't.
2  You can take tests.   Either you have cancer or you dont                              .
3.  Your mole is able to be tested and is either benign or malignant.                      1
.
 
Not so easy with an alert from a cadaver dog because with only a scent and no physical material residue to test you cannnot know......................................
 
1. Whose scent it is
2. Whether the scent was deposited recently or decades ago.
3. Whether the scent was from that spot or brought in from elsewhere by cross contamination
4. Whether the scent is from above ground or below ground.
5. Whether the scent is from that spot or has drifted from elsewhere and collected there.
6. Whether it is residual scent from decomposed  body bits, i.e. fingernails, teeth, hair, semen  etc. from a living person, or whether it is from an actual cadaver.
 
Which is why Martin Grime makes it clear that because of all those variables, without corroborating (testable) evidence it is not possible to prove whether a cadaver had ever been there or not.

There are no tests on Eddie or Keela done by an independent authority; so we must assume that the best they can have been is similar to other scent dogs.

This article is not peer reviwed but is interesting.

Two cadaver dogs were tested. One for only three tests, one for 14. 3 tests is far to few to draw any firm conclusions, and 14 is far to small to draw any rigorous analysis of accuracy.

But note that the "14 test" dog had one false positive and one false negative- an error rate of about 14%- accuracy of about 86%. One test in the fourteen was a failure to ID scent that was there. One test in the 14 the scent was "identified" when it was not there.

There note:

"With an overall successful positive diagnostic ratio of id of blood scent of 17.5 for Frankie
and a positive diagnostic ratio of 7.6 for Buster and with negative ratios of 38.5 and 16.4 respectively,
it is clear that certain dogs have the ability to detect human blood scent in principal in both trial and
scenario training. Any conclusions must be drawn carefully as by the nature of this project there were
many limitations mainly due to lack of number of dogs to compare and the limitations of number of
trials that could be done at any one time and within the overall time frame of this project"

Here is the really frightening result, and it is peer reviewed and statistically valid with a complete analysis!

They set out to test the 'Clever Hans' effect. Clever Hans was a horse that could apparently do advanced arithmetic. Asked questions it would hoof the ground the correct number of times. It was shown beyond doubt that all the horse was doing was reacting to the audience and handler's body language and stopped hoofing when it saw the expectation- if it was asked a question out of site of the handler and audience that knew the answer, it could not do arithmetic.

This current examination was most unfair, but very indicative. No scents were used at all! But the handlers not only knew that the experiment was to test for the scent, but also believed that certain identifiable items were imbued with the scent. Their dogs magically identified the scent reliably- but only reliably with the handler's supposed 'knowledge'. The handlers were unconsciously cuing the dogs.

An analysis of the US approach to Cadaver Dogs evidence- concluding that a reaction is not stand alone evidence, but requires further support:

http://www.policek9.com/Fleck/Cadaver%20Dogs.pdf

"The question that remains is the cadaver or human remains dog. Is this dog a
human scent dog or a contraband substance dog?
There is no Federal or State case law, that I’m aware of, that addresses an alert
from a cadaver or human remains dog as probable cause to obtain a search
warrant, search or arrest.
Therefore, if the cadaver or human remains dog is placed in the contraband
substance dog group, that alert would stand alone. If the cadaver or human
remains dog is placed in the human scent dog group, that alert would have to be
corroborated by other evidence.
Based upon review of the case law below, an alert from a cadaver dog is only
reasonable suspicion. The dog alert must be corroborated by other evidence. "

The Komar tests:

http://www.ncbi.nlm.nih.gov/pubmed/10097372

"A 1998 study by Debra Komar at the University of Alberta, Edmonton, analyzed and interpreted the effectiveness of eight dog and handler teams at locating simulated animal scattered or scavenged human and animal remains among snow and leaf cover. Tests consisted of "blind searches" or trials in which handlers did not how many items to search for or where they were hidden. The items included dry human and animal bone, and gauze and small articles of clothing soaked in human decomposition fluids and then dried. The study revealed considerable variation in the success rates of the dog-handler teams. The individual dog-handler teams had success rates ranging from 55 to 95% over the trials, and the overall recovery rate for the trials was 81%."

Note range of 55-95 with median at 81%- two in ten reactions were errors on average. Note- peer reviwed and statistically valid.

The outlying study by Oesterhelweg et al.

This is often quoted and is the most supportive of all published papers. It gives accuracies of about 90% over a small number of tests that are not statistically valid- no confidence limits are given.

Even on this basis, one in ten reactions is false.

Inside or out does not matter. What does is the low success rate.

The highest claimed rate of one false result in ten; I suspect it is much lower.

The Clever Hans experiment is the most worrying indicating considerable handler cuing.

No, the scent isn't preserved as well outside than inside.
All professionals are aware of the Rosenthal effect. The PDL operation was supervised by Prof Harrison MBE. There was no motive for that effect to occur, but all motives for the dogs and the handler's reputation to be confirmed. A negative was as informative as a positive, Prof Harrison MBE, when he sent the dogs to the flat, knew there was no cadaver there, buried in a wall or under the floor.

In one of the videos, Eddie gets very excited around a bed and keeps going round it and then he (or it could have been Keela) gets very excited about what is behind a sideboard and keeps going back to it.      At the end of the video Grime explains that upon investigation they found food under the bed and a ball behind the sideboard - so it would seem the dogs 'getting excited' - doesn't only apply to the scents they are trained to find.
 
One wonders why - being such highly trained dogs, that they did not simply ignore the scent of food under a bed and the scent of a ball behind a sideboard.

If the dogs are as unreliable as you suggest,  why were they paid more than a Chief of police   ? 

Indeed,  why would they be used at  ALL   ? 

The dogs' evidence  (  and it IS evidence, regardless of there being no conclusive forensic material found  )   has always been,  and remains, the biggest thorn in the McCanns' side

They were not- that was a tabloid myth/lie. Unless you can provide a cite.

They are indicative- they have the ability possibly to increase above pure chance a location to search for usable evidence. Their handler agrees.

And yet,  despite an  international search for a legal precedent regarding  the 'unreliability, of cadaver dogs the only case the McCanns' lawyers could come up with was  Zapata

Gerry confidently recited the Judge's findings  (  that the dogs were unreliable  )  giving a detailed description of the tests the dogs were set  ...  and the statistical conclusion

Except,  of course,   Zapata subsequently confessed that he   had  murdered his wife  (  and  chopped her body up before disposing of the parts in various landfill sites  )

There are several scientific investigations, none of which support infallibility.

Zapata is one case among many. Eddie and kEELA WERE NOT CONFIRMED TO BE RIGHT IN pDl OR jERSEY.

What do you make of the Clever Hans experiment- 30% positive IDs to no scent at all- just because the handlers thought they knew which place was contaminated.

It would help if you read the thread rather than taking a scatter gun approach to anyone who disagrees with you.

I was referring to:

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3078300/

"Our aim was to evaluate how human beliefs affect working dog outcomes in an applied environment. We asked whether beliefs of scent detection dog handlers affect team performance and evaluated relative importance of human versus dog influences on handlers’ beliefs. Eighteen drug and/or explosive detection dog/handler teams each completed two sets of four brief search scenarios (conditions). Handlers were falsely told that two conditions contained a paper marking scent location (human influence). Two conditions contained decoy scents (food/toy) to encourage dog interest in a false location (dog influence). Conditions were (1) control; (2) paper marker; (3) decoy scent; and (4) paper marker at decoy scent. No conditions contained drug or explosive scent; any alerting response was incorrect. A repeated measures analysis of variance was used with search condition as the independent variable and number of alerts as the dependent variable. Additional nonparametric tests compared human and dog influence. There were 225 incorrect responses, with no differences in mean responses across conditions. Response patterns differed by condition. There were more correct (no alert responses) searches in conditions without markers. Within marked conditions, handlers reported that dogs alerted more at marked locations than other locations. Handlers’ beliefs that scent was present potentiated handler identification of detection dog alerts. Human more than dog influences affected alert locations. This confirms that handler beliefs affect outcomes of scent detection dog deployments."

Your statement is unsupported and does nothing to counter the scientific findings.

The case you cite does not confirm the detection of a cadaver as no body was ever found and the case is going to appeal.

You really need to address why the dogs in the experiment alerted one time in three to no scent when their handlers believed there to be scent there.

Dogs do lie and give false alerts when they are influenced by the beliefs of the handlers.  And that is a proven fact.

Not all sniffers dogs are good, but those whose handler intends to be professional have to be excellent.

Well no,  Benice  ...  that is not an undeniable  'truth' 

Let me explain

The weather man said tonight that it will rain tomorrow  ....  that is an undeniable truth  ...  he said  it

He  might  be wrong, and it  might  not rain  ...  but that is not an undeniable  'truth',  it is merely a proposition 

In the same way,  saying that the cadaver dog  might  have been wrong, is merely a proposition  (  rather than an undeniable    'truth' )

In short,  that which  IS  true,  stands apart from that which  MIGHT  be true

The only undeniable  'truths'  we have,  in this instance are  :

1 )  A child disappeared without trace, never to be seen again

He's alluding 1) to a notion of scent cone which is well developed in the Cadaver Dog Handbook and 2) to the extreme volatility of cadaver scent molecules chased by draughts and trapped in corners where they end up penetrating in porous material like paint.

Don't be silly. The reactions of the dogs is quite in line with no corpse ever being anywhere that they reacted. Mr Grimes evidence is quite clear that reactions may be unsupported by evidence. Both Grimes and Harrison are very aware that the academic research shows that dogs do have a measurable failure rate.

You  do  accept that,  statistically,  the cadaver  dog was more  likely to have been accurate in his alert in Apartment 5A,    than innacurate  ?

Both Grimes and Harrison are very aware that the academic research shows that dogs do have a measurable failure rate.
Prof Harrison knew that no corpse was inhabiting the flat, whether inserted in a wall or under the floor. Therefore he knew that finding remains was excluded.
As you don't seem to realise, volatile odorous molecules, absolutely impossible to catch (though the thesis I sent a link to explains how works the device built to trap those molecules), remain in the air of a "controlled environment" like a flat. Prof Harrison knew these molecules remain there for quite a long time. This is why he sent for two exceptional dogs.
Had the cadaver dog not alerted in the 5A (as in any other flat occupied by the group, by the McCanns after the disappearance, nor in the Murat villa and the McCann villa), Prof Harrison would have been happy to exclude a death in the flat.
As the dog exhibited immediate excitation and alerted in four places, somebody had died in the flat or a dead person had transited there, but who ? That's the rub.

So don't you believe Grime when he says his dogs cannot distinguish between the scent from a dead person or  the same scent from various body bits and bodily fluids from a live person? 
 
If Eddie had spent the same amount of time in other apartments/cars as he did in 5A and the Renault - he may  have alerted in one or more of those other places.   Or conversely,  if Eddie had only been allowed to spend the same small amount of time in 5A and the Renault as he did in those other places, he many not have alerted in 5A or at the Renault.     

For example:-  After 30 seconds (i.e. the maximum time spent on the other cars) Eddie had not alerted.   After 30 seconds spent on the Renault the result was the same - Eddie had not alerted. 

Unless the same amount of time is spent at each site/object - then clearly the tests cannot be regarded as unbiased.

Just to be clear  (  given your penchant for statistics ) 

You  do  accept that,  statistically,  the cadaver  dog was more  likely to have been accurate in his alert in Apartment 5A,    than innacurate  ? 

...   and that,  consequently,  it   is    ( statisically  )   more   likely that a dead body had been in the apartment where the missing child was last seen,  than for there not to have been  ? 

Just to be clear

Statistics do not mean anything for a sing;e event in terms of the likelihood of that single event- they are an indication of likeliness over many trials.

It is as indicative as the statistic that most harm to children comes from parents or carers, rather than strangers, but that is no evidence in a single instance.

The important thing to grasp is that it is totally possible for the dogs to have reacted as they did and yet there was no cadaver scent present at that time. Can you accept that as a possibility.

As Grime says, the indications of the dogs are only confirmed if further forensics were found. In the matter of cadaverous material they were not.

Your last sentence is totally false and even Grime woyld not agree with it.

It is perfectly possible (as I state above) for the dogs to have reacted as they did, yet there was never any cadaverous material present.

Additionally, you show that you misunderstand the dogs completely when you say that 'the' dog alerted. Ittakes two reactions- an alert from the VRD dog and a non alert from the blood dog as Eddie reacts to blood from a person who is still alive as one of his behaviours.

The number of times Eddie was called back is an excellent example of the Clever Hans effect. Grime knew that that was the McCann's car becasue of the posters. If you analyse the video, Eddie was called back about ten times (never more than once with any other car) and spent more time with the McCann's car than any others, even before alerting, meanwhile obviously alerting in distress to a blank wall. A defense lawyer (and an animal psychologist) would have torn the evidence in the garage to shreds!

Eddie can't distinguish between the body of X and the body of Y.  He can't distinguish between the scent of X's remains, discovered after days, and the scent the remains of X left where X died, before X's body is taken to the incinerator.

You may find that funny, but any fair and unbiased viewing of the video shows that Grime made Eddie return time and time again to the McCann's car. Same with cuddle-cat.

Your insistence in pretending that Mr Grime (and his supervisor, Prof Harrison) didn't allow Eddie the time to eventually react similarly in the other places is false. There is an obvious reason why Eddie spent less time in the other places.

It is difficult to assess the apartments search as the video is discontinuous, but the garage search of the cars shows definite bias towards extra time and extra recalls to what was known to be the McCann's car.

I saw the video too Anne.  Grime might as well have put a marker on that Scenic, the poor dog was exasperated at being called back so many times.  The entire operation was an exercise in futility IMO.

As for the car itself, what a cock up!!  The police driver was unprotected and they drove it to the underground car park.  A rental car which  hundreds of people have previously used and they expected to find something unique to the McCanns??

Ok, a couple of points that haven't been made:

This wasn't an experiment, it was a live exercise. If it was an experiment it would have been useless for all the reasons stated. I.e spending more time in one area than others.

My biggest problem with scent dogs was handler bias. I'm aware of teh clever hans effect. I've posted an experiment with corpse scent on carpets previously which was blinded and there was still an 80-90% success rate.

On first watching the garage video I dismissed it as a clear example of handler bias. I then watched Mr Grimes do exactly the same in the apartment with one of the single beds. He called Eddie back repeatedly, over and over again, both on the bed and under the bed. Eddie never signalled at the bed. If the dog was going to be badgered in to giving a  false positive, he'd had been forgiven for doing so at that bed.

Mr Grimes makes a lot of money from having accurate Cadaver dogs. He will lose work if his dogs provide false signals. He knows his dogs. If he thought that encouraging his dog back to one place repeatedly would cause the dog to give a false signal, he wouldn't do it. A false positive would lose him work, no bark wouldn't.

The Clever Hans effect has nothing to do here, what handlers are aware of is something else, called the Rosenthal effect.

I didn't invent this title. No, it doesn't give him more credits, but I observed that posters criticized Mr Grime and not Prof Harrison who was in fact the head of the operation. For a time they even ignored he was a professor. So I deduced MBE impressed the British !

As far as your comment about Grime having nothing to gain- cuing is often unconscious- the handler does not realise they are doing it.

This is true.  Not only do the dogs need to be regularly tested - so do the handlers IMO - simply because cueing can be unconscious - and result in false alerts.

Should be a thread just for Zapata, because didnt the McCanns use this case to show how the dogs evidence was a waste of time.

Shame that the judge decided to ignore their findings when the bloke admitted to killing his wife what a year later in 2008.

So the dogs indicated correctly AGAIN.

Dogs go forwards, from the weakest to the freshest scent. Hence the importance to let them start from the exact place where the missing person was last seen.
In Madeleine's case, there were two possible exits, but I'm afraid only one was offered to the dogs, forcing them on an out track.
If the dogs had been set free at the Tapas, they'll likely do the last route Madeleine took to go back home after high tea.

GNR tracking dogs that searched the next day. Anne makes a good point that they should have done another search from the start/tapas bar of her last known route back to the apartment at 5.40.

"When she finished jogging, at around 5:20/5:30 p.m., she went to the Tapas area. Gerry was there, as well as the twins and Madeleine who were having dinner at separate tables. Madeleine had been taken to the area by the nannies. Her parents were required to sign the register when the meal was over, at around 5.30 p.m. They arrived at the apartment at around 5:40 p.m., earlier than usual, because Madeleine was tired, their other friends were at the beach and Gerry had an all-male tennis game at 6:00 p.m."

If my memory serves me right the GNR used sniffer dogs. Air sniffer dogs, sniff the air they can go back or forward , however they probably had trackers too. I will try and find a link.

Given that Madeleine had walked around the complex for several days it is not surprising that the sniffer dogs found her scent.  My point is though that it would be impossible to differentiate between that innocent scent and that related to any abduction.

But didn't Kate carry the child, because she was tired ? Tracker has its nose to the ground, so doubt if that would work anyway. If she walked out the front or side door it should track her, so its unlikely she wandered off.

The dog has its nose on the ground because cells and volatile molecules fall on the ground whether coming from hands, head, knees...  A barefoot person is the best for the dog. Madeleine is supposed to have disappeared barefoot.

As the departure point was the main door, the route taken by all dogs seems to indicate it was the strongest track (vs an eventual route through the car park on which there's no certain statement). It is a pity the door-window wasn't offered as a point of departure for the dogs.
What seems clear to me is that if Smithman (getting out through the main door) carried an alive Madeleine, the dogs hadn't turned around the building. If Smithman went out through the door-window and then the path alley carrying an alive Madeleine, the dogs had turned right, not left, when arriving on the path alley.

If Smithman went out through the door-window and then the path alley carrying an alive Madeleine, the dogs had turned right, not left, when arriving on the path alley.

And the reason the cadaver dog was brought in is because they had to investigate the tragic hypothesis that Madeleine wasn't alive when Smithman took her out of the apartment so those GNR dogs wouldn't have found that trail. The cadaver dog only alerted at the back not the front so that's a good indication on where she left from using that hypothesis.

What do you mean, Pathfinder ? Eddie smelt the scent he had been trained to as soon as the (main) door was opened. He alerted on the flower bed, seeming to mean that a body had been lying there for while. Can a cadaver dog follow the trail of a carried body ? Possibly, but how long after ?
Cadaver dogs originate from rescue dogs. Some handlers discovered that air sniffing dogs were repelled by cadaver scent. That gave them the idea of selecting those dogs to send them on disaster places, once the rescue ones had found whoever could be found alive.

"Back" and "front" are confusing : when you look at the building, actually the north part seems to be the back and the south one the front as long as you imagine the door-window is a door (can be opened and shut from either side).
I don't see how the flowerbed's alert means that Smithman left through the door-window (though he likely did so, dark and desert alley, except for a few steps easy to control).

Yes I understand what you mean, it can get confusing. Yeah back means path side/tapas side. To get to the flower bed you have to descend the stairs into the garden so unless Madeleine fell from the balcony, she would have to be moved there before leaving IMO. Check coast is clear scenario.

p.s. also interesting scent indicated outside parent's bedroom patio doors and nothing at the main back patio door. Eddie was very interested in sniffing that wall/climbing plant. Hypothesis - she left the apartment from the wardrobe through bedroom patio door.

If Madeleine had fallen from the balcony, she should have remained there at least for an hour for Eddie to alert. A lot of time before finding her. And it could be an accident, sleepwalking, not really neglect.
The order wardrobe corner, balcony, flowerbed seems more plausible. It is possible that rain or cleaning water dragged the volatile molecules towards the flowerbed.

I don't believe she fell from the balcony. Agree with you - wardrobe, balcony, flower bed. They took some of the climbing plant as possible evidence. I'm not sure but I haven't heard it was raining that night or morning of the 4th when they were all out searching. I wouldn't think it was water. If she went out the gate she may have been placed down briefly at the flower bed to check all was clear.

Didn't all the dog handlers give statements to the effect that her scent was only detected from the front door.  Apologies if I got that wrong as it is a while since I read them.

A carried child will leave virtually no scent and by the time the GNR dogs arrived any residual scent there was was well gone, blown away by the breeze that morning.  My belief is that the scent the dogs detected hours after Madeleine was found to be missing was scent laid down by her as she walked out of the apartment with her parents.

Ergo, if she had merely walked out the patio door and down the steps to the road the sniffer dogs would have been on it instantly.

What Eddie found in the flower bed was probably cat poo.

No. They likely ignored that the door-window had been left open and used like a door.

Why ? I spoke to a handler and he said the carried child would leave scent, a fortiori if barefoot.
and by the time the GNR dogs arrived any residual scent there was was well gone, blown away by the breeze that morning.
The first dog to pick up her scent did it at 2am.

Absolutely right John.  Anne you are off the mark on all these points.

However I think that Anne is correct that the garden bed was NOT in view of the Tapas restaurant because the walls and hedges to the walkway between the apartments and the tapas restaurant would have prevented that view.

Let's not forget that 5A was built out from a hill.  The front entrance was at ground level, but the rear was raised to almost first floor level.  Remember the steps up, eleven IIRC.  A modern house often has 13 steps up, between floors, and each is usually about seven inches high.  These steps seemed fairly normal in height so presumably the back of the patio was about 77" above the garden immediately below.

The garden then further sloped down towards the walkway

This is why I wanted to see the footage (if it exists) when they went back the next day in the daylight to do a further checks at the flower bed. It is hard to get the full facts from the night time footage - Grime said he wanted to come back the next day as further checks were required. I know Eddie was very interested in the balcony outside the parents bedroom and he was sniffing that wall/climbing plant a lot as you can see in the footage. He was not interested in the main back patio door entrance. He alerted in the flower bed in the garden. I believe some climbing plant branches were collected for possible evidence. Now scent shouldn't be collected in the flower bed at the bottom of the steps unless there is a possible reason for it e.g. a body being there only for a short time i.e. light scent detected.

The cadaver body hypothesis sequence:

1. Behind Sofa
2. Wardrobe
3. Exit through Parent's Bedroom Patio Door to Balcony
4. Down steps to flower bed
5. Exit through gate.

I.m not sure what you are looking for, but you will find it in McCann files
I don't know if the following is any good on the cadaver and blood sniffer dogs. I thought the front was by the front main door, which I believe also has a flowerbed. All the dog reports are in the files



1. Apartment 5 A, OC resort from which the girl disappeared

- Cadaver odour dog
• in the couple’s bedroom on the floor next to the wardrobe.
• In the living room, behind the sofa, next to the lateral window of the apartment.

2. Patio area, in front of apartment 5 A

- Cadaver odour dog
• in one of the flower beds, the dog handler commented upon the weakness (lightness) of the odour detected.

3. Apartments where the rest of the group was staying

• Nothing was found by either dog.

4. Residence of the McCann couple at the time of the date of inspection

• Nothing was found by either dog in the villa.

5. In the locality of P da L

• Nothing was found by either dog.

6. The clothes and belongings of the McCann family

- Cadaver odour dog
• on two pieces of clothing belonging to Kate Healy.
• On a piece of clothing belonging to Madeleine.
• Possibly, on a soft toy belonging to Madeleine (cadaver odour was detected when the toy was still in the residence (on the date it was occupied by the family)).
• Signalling was confirmed in a scenario outside the villa.

7. In the vehicle used by the McCann family

- cadaver odour dog
• signalled the car key

- blood dog

* signalled the vehicle’s key.
* signalled inside the vehicle’s luggage boot.

8. In a vehicle used by a friend of the family who was staying at the same resort, coinciding for a few days.

• Nothing was found by either dog.

9. In all the cars used by Robert Murat and people close to him

• Nothing was found by either dog.

(Of a total of 10 vehicles the cadaver odour dog and the blood dog only signalled the vehicle hired by the McCann family on 27th May).


The places and objects signalled by the blood dog were tested forensically by the reputed British Laboratory (FSS) whose final results are not yet available. However, there are indications that would show that these will be inconclusive, in other words they do not corroborate the dogs signalling without leaving any doubt.

Based upon the action of the sniffer dog team which reveals the eventual existence of a cadaver in the apartment and in the car used by the McCann family and with the aim of enabling Gerald and Kate to safeguard their position in the process they were constituted arguidos, in the face of the mere possibility of their involvement with the eventual cadaver. During the course off their interrogation as arguidos they denied any responsibility in the disappearance of their daughter.

So the flower beds that I am looking at are on the area behind the wall separating the main door from the car park

This must be what was discussed about the tracker dogs heading for lote 6 apartments car park across the road
I have to say that I think the police and all the help given by, villagers, helicopters, volunteer planes flown in line along the area, boats, motorbikes, extra dogs to assist in search, done a fantastic job of searching and all the police had a 7 day cancellation
on leave days

Anyway here is the confusing bit and it makes me think that there is a fair possibility she would have been abducted through the unlocked front door(by car park) and transported to that car park

- Completing the internal search of Block 5 - the verandas of access to the apartments - and when outside, the dog turned toward [directed itself to] Block 4. However, at the corner of Block 5, it turned left heading for the path between the building and the leisure area - pools and restaurant - going on to turn left [again], i.e. going around the building, setting out for the main street, crossing the road to the wall of Block 6. There, it sniffed the bottom, turned to the right - going down the road - taking itself to the car park next to Block 6 where its search [took it] to a lamppost where it then became confused and stopped the search.

It would be better, though too late, to speak of north and south sides. There's no flower bed on the north side. The flowerbed is not at the bottom of the steps. A Bougainvilliers is growing there.

Agreed we will call it the south side. "We've searched the outer perimeter and there is some interest here but it will take further examination to see what's going on." (Martin Grime from night time footage)

- Cadaver odour dog
• in one of the flower beds, the dog handler commented upon the weakness (lightness) of the odour detected.

You could hide a body for a short time inside those bushes in the flower bed next to wall where Eddie is seen alerting below? Maybe if discovered it's accidental death from a fall from balcony.

So the flower beds that I am looking at are on the area behind the wall separating the main door from the car park

This must be what was discussed about the tracker dogs heading for lote 6 apartments car park across the road
I have to say that I think the police and all the help given by, villagers, helicopters, volunteer planes flown in line along the area, boats, motorbikes, extra dogs to assist in search, done a fantastic job of searching and all the police had a 7 day cancellation
on leave days

Anyway here is the confusing bit and it makes me think that there is a fair possibility she would have been abducted through the unlocked front door(by car park) and transported to that car park

- Completing the internal search of Block 5 - the verandas of access to the apartments - and when outside, the dog turned toward [directed itself to] Block 4. However, at the corner of Block 5, it turned left heading for the path between the building and the leisure area - pools and restaurant - going on to turn left [again], i.e. going around the building, setting out for the main street, crossing the road to the wall of Block 6.

There's a wall there inside the climbing plant on the balcony - the body would be on top of the wall or ledge hidden inside the climbing plant. Where Eddie is sniffing below. I could do with finding images of the wall from the balcony bedroom window side which would be helpful.

It is my view that it is possible that the EVRD is alerting to 'cadaver scent'
 contaminant or human blood scent. No evidential or intelligence
 reliability can  be made from this alert unless it can be confirmed with corroborating
 evidence. The remainder of the vehicles were screened by the EVRD without
 any interest being shown. Therefore the CSI dog was not further deployed.


My professional opinion as regards to the EVRD's alert
 indications is that it is  suggestive that this is 'cadaver scent' contaminant. This does not however
 suggest a motive or suspect as cross contamination could be as a result of a
 number of given scenarios and in any event no evidential or intelligence
 reliability can be made from these alerts unless they can be confirmed with
 corroborating evidence.

As someone who demands 'absolute certainty' I'm surprised that you should decide to ignore the man who knew most about the abilities of his dogs.

AS far as I know  -  Grime has never once used the word 'cadaver' i.e. dead body - only the word  'cadaverscent' - i.e. residual odour from decaying cellular material.  And that is because he is fully aware that in the absence of corroborating evidence -  any such material alerted to could have originated from a dead body OR a live one.  The dog cannot indicate which - and neither can Grime.

Scent dogs - there are good, better, and almost infallible.

Eddie and Keela were regarded as part of the last group.

A lot depends on the relationship between handler and dog, and PC Martin Grime is the best also.

The dogs were owned and trained by the UK police (South Yorkshire?) and were working members of the constabulary as was PC Grime.

Anyone wondering about their skills should check out the Long Island SK case.

The killing fields were only located because an off duty dog handler took his off duty scent dog for a stroll one day.

Help me here:

Cadaver Dogs are trained to locate and follow the scent of decomposing human flesh, that much I know. Having alerted in  5A, are you actually saying that the scent the dog  alerted to was from an alive/dead person? Sort of like someone suffering from gangrene?

Hi Carol

Welcome by the way.

Hope this helps you

http://csst.org/forensic_evidence_canines.html


We call Eddie a Cadavar dog but in actual fact he is a Forensic Search Dog.

However, originally he was trained as a search dog for living humans so he would have been trained as a Decomp Dog  A term used to describe a canine that will indicate when a scent source is living human tissue, blood, semen, urine, feces, and materials that have been handled and worn by humans.



A dog can never be detrained to forget what he has earlier been trained so he is likely to alert to living human tissue, blood, semen, urine , feces and materials that have been handled and worn by humans as well as scents sourced from decomposing human tissue.


What a brilliant nose he has, but it seems that he is flawed because he may alert to living as well as decomposing bodies etc.  It clearly states in the Forensic Search Dog. section that a FSD should never have been crosstrained.

Eddie was.



Forensic Search Dog (The primary focus of this paper)
A canine that has been specifically trained to indicate a scent source as being from decomposed human tissue. Such animals are also trained to exclude (deconditioned to) the scent of human urine, feces, and semen and will not alert on residual scent from a live human; and have never been trained to locate any scent other than that of decomposed human tissue.


Hope this helps.  Eddie the dog that we call a Cadavar Dog is actually Forensic Search Dog and a Decomp Dog.

Because of this he might alert to living matter, such as blood, urine, feces semen etc from a living person as well as Decomposed matter from a dead person



Sorry, but because of his cross training it seems that this brilliant dog, Eddie, wasn't up to the task in hand.



He was also trained on dead pigs, so it is likely that he would alert to Dead pig, I think.



It is a complicated subject and we are still learning.   Hope this helps you.

No idea but it is my understanding that he was a search dog originally.  Searching for living humans in catastrophy areas, like earthquakes, I suppose.

Search dogs are trained to recognise living human scents.


You cant get a dog to unlearn skills that he has already been taught, so Eddie has two skills


.... but unfortunately this means that in the searching for scents of the dead, he is marred because he also will alert to living scents.

No I dont do cites any more cos my eyes will not allow the in depth reading needed.


But there have been mentions of it on here.  I fancy that Martin Grime stated that eddie was a search dog before.

Perhaps some one can remember?

Sniffer Dogs 'Can Hinder Police Work'
HOMEPAGE NEWS REPORTS INDEX NEWS MARCH 2011

 Police sniffer dogs used to find missing people and dead bodies "urgently" need better training and monitoring, according to an official report. 

(http://www.gerrymccannsblogs.co.uk/press/47march11/sky-25-3-11-eddie.jpg)

Sniffer dog Eddie was relieved of his police duties

 The Government's National Policing Improvement Agency (NPIA) said specialist victim recovery dogs are not trained to approved standards, with no way of gauging their competence.

The NPIA reviewed the use of the specialist sniffer dogs two years ago, but its report has only now surfaced following a request by Sky News.

"There is no consistency in what the dogs can do and how it is done," the report states.

"Furthermore, there is no national standard for accrediting dogs and handlers or record keeping of the success rate they achieve."

The report added the dogs, which are trained to detect the smell of dead bodies, have "the potential to cause complications in an inquiry".

"There is an urgent need to have national policy on their training, accreditation and deployment," it concluded.


 

The review uses a kidnap investigation to highlight how dogs have tied up valuable police time.

The animals detected human remains in old furniture that had been bought from houses where the owner had died.

The use of victim recovery, or cadaver dogs, has proved to be controversial in a number of high-profile cases in recent years.

A South Yorkshire Police spaniel called Eddie was said to have sniffed out the "scent of death" at the Haut de la Garenne children's home in Jersey and the apartment from which Madeleine McCann disappeared in Portugal.

But in both cases nothing more was found and South Yorkshire Police say Eddie is no longer working with them.

Sniffer dogs hindered the police probe into Shannon Matthew's disappearance
 

Victim recovery dogs from four different police forces were used during searches for kidnapped schoolgirl Shannon Matthews in Dewsbury in West Yorkshire in 2008.

The dogs found evidence of dead bodies, but officers later discovered the corpses were nothing to do with her disappearance.

"The properties searched contained a high level of second-hand furniture bought from dwellings where someone had died," according to the NPIA report.

"This resulted in numerous indications that required further investigation to confirm whether they were connected to the investigation, or to previous owners of the furniture."

The Association of Chief Police Officers told Sky News it was consulting individual police forces and hoped to have national training standards for the dogs later this year.

Sorry about that, Sadie.
 
He was a victim recovery dog who search for victims alive or dead, but he was Enhanced which was the “E” in EVRD, I believe that was because he had trained to detect cadavers and cadaver scent as well as blood.
 Hope that is understandable. If anyone knows this to be wrong please correct it.

Here he is described as a blood dog

Thanks Anna. Sorry, I tend to forget about sticky threads. That "article"  detailing how a cadaver dog correctly alerted to cadaver odour but which confused police as it had nothng to do with the missing child doesnt really help vis a vis some stating that Eddie was a live person recovery dog or "wasnt a real cadaver dog". I would need something a little more specific to him than generic talk about sniffer dogs.

Eddie the sniffer dog - the animal that had supposedly found the 'scent of death' in the Portuguese flat where Madeleine McCann disappeared - no longer had a licence for UK police forensic work when Harper started using him in Jersey. Eddie, whose owner, Martin Grime, was paid £93,600 for less than five months' work, triggered the first excavations by barking at a spot where Harper's team then unearthed what was claimed to be part of a child's skull. In fact, as a Kew Gardens expert has now confirmed, it was a piece of coconut shell.

How was it ascertained that it was actually a piece of coconut shell which prompted the alert or is this just implied and trotted out by those motivated to discredit the dog/handler ?

I mean.......he couldn`t see it!

Did the dog confirm the alert to it in isolation after it was unearthed?

My mistake. I meant have you  watched Lenny Harper ex Jersey police chief! on video smashng the myths? It's a good listen, especially regarding the "coconut shell" from around 6 minutes onwards. Let me have your views on what he says. He was, after all, there himself, which IMO must trump any rag's "story". The devil is in the detail.

Having played with Ccat, and not alerted  ......  Eddie then  alerted to Ccat , or so said Martin, in a cupboard.

Trouble was that Eddie had already passed Ccat three times close to and NOT alerterd.

He actually alerted to something on top of the cupboard, which looked like a pile of folders with a sheet of paper on top




Martin completely misconstrued that .... and you must know that.

The last time you accused me of that it was you who was wrong. In future please check your facts before accusing others. In this instance I prefer to listen to an experienced dog handler rather than an amateur sleuth with a biased agenda;

'Can you confirm if the signal given regarding the stuffed toy corresponds to a concrete alert of detection of a cadaver, or a mere trick played by the dog''
The dogs were not taught any 'tricks'. EVRD 'signalled' the toy, which at my request was retained by the Judicial Police for future forensic analysis. I have no knowledge of the results of any forensic analysis on the toy.

I believe that this report was Feb 2008.

From the screening of the videos, referred previously, done when the dogs were working, some doubts arise. We don't want and we can't take the place of the trainer, we only wish to alert, with this paragraph, to some facts, that according to us, need further clarification.

If the dog is trained to react when he detects what he is looking for, why, in most of the cases, we see the dog passing more than once by that place in an uninterested way, until he finally signals the place where he had already passed several times'

On one of the films, it's possible to see that 'Eddie' sniffs Madeleine's cuddle cat, more than once, bites it, throws it into the air and only after the toy is hidden does he 'mark' it (page 2099). Whys didn't he signal it when he sniffs it on the first time'

Apart from all that was said about the dogs, we must also take into attention the results of the forensic analysis that was performed by the experts on the Scientific Police Laboratory on the day immediately after the facts, and already mentioned where no vestige of blood was found.

I have trawled your posts and found this;

http://csst.org/forensic_evidence_canines.html

The descriptions of the different dogs don't seem to compare with anyone else's descriptions, that's the problem here. Using their criteria and Grime's description of his training Eddie was not one of these;

Cadaver Dog
A narrow term, used in a search-and-rescue context, to indicate a canine primarily trained as a tracking or air-scent dog that has also received cross training in the location of dead human bodies

He was one of these;

Forensic Search Dog (The primary focus of this paper)
A canine that has been specifically trained to indicate a scent source as being from decomposed human tissue. Such animals are also trained to exclude (deconditioned to) the scent of human urine, feces, and semen and will not alert on residual scent from a live human; and have never been trained to locate any scent other than that of decomposed human tissue.

Hopefully I have found the document you have been referring to, and have explained why I dismissed their description of a 'cavader dog' as not referring to Eddie.

Eddie was trained on human blood and dead Pigs.

He alerted to blood from the  living(Gerry for one) and IIRC he alerted to semen(from a living person I presume) in Jersey.

A cadaver dog can find something as small as a single tooth or a drop of blood.
SAR dogs will alert to remains if they find them

Eddie was basically a Forensic search Dog ....   BUT !!

The first sentence in black is what Eddie was intended to be

... BUT, looking at the part in blue

Eddie had already been trained to alert on residual scent from a live human, which includes the scent of human urine, feces, and semen    Once trained, the training cannot be detrained.   So he is always likely to alert to the scents of a living human human   

So seems that makes him ineffective, because when he alerts there is no way of knowing whether it is to odour from Madeleines dead body OR residual odour from her living body ... or even blood from a living persion .... or the scent from a dead pig / pork [He was trained using dead pig rather than dead human parts]


The final part in red:

States that he MUST NEVER have been trained to locate any scent other than that of decomposed human tissue. .... but he has !

Therefore poor Eddie whilst having a brilliant nose was unable to "definitely say" whether he was alerting to the scents from a dead body, a living Madeleine, dried blood, or pork.


Forensic Evidence was necessary .... and there was none


The long and short of it is that we just dont know what he alerted to.
You cant hang, draw and quarter the Mccanns on such unsubstantiated alerts, can you?   
And there is nothing else of any substance at all against them


Gunit, I am not very good at explaining things.  Hope you understand


And a big thank you to Anna for her input.

Eddie had already been trained to alert on residual scent from a live human, which includes the scent of human urine, feces, and semen    Once trained, the training cannot be detrained.   So he is always likely to alert to the scents of a living human human   

So seems that makes him ineffective, because when he alerts there is no way of knowing whether it is to odour from Madeleines dead body OR residual odour from her living body ... or even blood from a living persion .... or the scent from a dead pig / pork [He was trained using dead pig rather than dead human parts]


The final part in red:

States that he MUST NEVER have been trained to locate any scent other than that of decomposed human tissue. .... but he has !



Therefore poor Eddie whilst having a brilliant nose was unable to "definitely say" whether he was alerting to the scents from a dead body, a living Madeleine, dried blood, or pork.


Forensic Evidence was necessary .... and there was none


The long and short of it is that we just dont know what he alerted to.
You cant hang, draw and quarter the Mccanns on such unsubstantiated alerts, can you?   
And there is nothing else of any substance at all against them


Gunit, I am not very good at explaining things.  Hope you understand


And a big thank you to Anna for her input.

So, is there a reference which tells me this? If so, I'll go and look for it;

Eddie had already been trained to alert on residual scent from a live human,

It seems counterintuitive to say that a dog cannot be retrained. If it can be trained in the first place then I see no reason that it's alert parameters can't be changed given similar training methods. Just another myth stated as a fact.

It originally came from a document that Lace posted a link to, which appears to have been deleted

BUT this post by Lace has a portion of that document in it


This is the part of the article I posted a link to that tells it all as far as I am concerned -


2) Dogs specifically trained to detect scent of decomposed human tissue can be invaluable in resolving issues related to evidence gathering and determination of investigative direction. It is crucial, however, that dogs be used in situations appropriate to their training level, and that dog handlers are able to support their testimony about dog behavior with accurate training logs. Any canine used for forensic purposes in the location of the scent of decomposed human tissue should never be cross-trained for any other type of scent work if the results of the animal's activities and handler's opinions are to be used for the development of probable cause.


Eddie was trained as a rescue dog first of all,   in which case he would have been trained to detect live human bodies.

When Eddie alerted in the living room behind the sofa,  he alerted exactly where Keela had,  the exact spot, so was obviously in my opinion alerting to may be blood.

If Madeleine had lain behind that sofa long enough for the scent of a cadaver to be apparent,  then Eddie would have been alerting to whole of the area behind the sofa.

Eddie was panting so he was obviously tired and hot,   Keela wasn't panting.

When did Grime retire Eddie?

When Lace comes in again, perhaps you would like to ask her the origin of the document that she was referring to?


To repeat:

Eddie was trained as a rescue dog first of all,   in which case he would have been trained to detect live human bodies.

And once a dog has been trained to respond to certain stimulii he cannot be detrained.


So, as well as odours from dead bodies

Eddie will always be likely to alert to living odours

It is made plain that once a dog is taught a skill and learns it, it cannot be detrained despite any retraining..

Something once learned stays with the dog.

Also:

Forensic Search Dog (The primary focus of this paper)
A canine that has been specifically trained to indicate a scent source as being from decomposed human tissue. Such animals are also trained to exclude (deconditioned to) the scent of human urine, feces, and semen and will not alert on residual scent from a live human; and have never been trained to locate any scent other than that of decomposed human tissue.

So altho it appears that Eddie has a brilliant nose, unfortunately he was a flawed for the sort of work needed in this case .

With Forensic Evidence then he might have been OK ,

BUT as you know there was no Forensic Evidence against The Mccanns ... therefore he found nothing of significance.


Now will you please excuse me.

The dogs have been used by police forces across the world and were called in to help with the Madeleine McCann investigation.
Both are springer spaniels, but the breed is no better suited to the job than any other. A dog just needs to show a keen sense of smell and it's the training that makes them good enhanced victim recovery dogs, says Mr Grime.
Eddie was bred by a specialist search-dog breeder and Keela came from the West Midlands Police breeding programme.
Both live with Mr Grime and have a normal life outside of work. He is currently training two new dogs, Morse and Lewis.
In the Jersey case, parts of a child's body were found on Saturday. The remains are thought to date from the early 1980s. Police have yet to say whether they are male or female.
[Thanks to Ferryman and Carana]


[And also today:  thanks to Brietta]

Eddie also alerted to semen, blood, milk teeth and coconut in Haute de la Garenne.
In fact, in the video I watched there were few places Eddie didn't alert.

I am not about to trawl thru all the Haute de Garenne videos, but Briettas word is good enough for me .... As Laces word was too



Satisfied now, Gunit, that Eddie is also a search and rescue dog as well as a Forensic Search Dog ?

Eddie was double trained.   Brilliant nose tho he has, unhappily he is a flawed dog, because of this double training, for a Forensic Search Dog

It clearly states that as a Forensic Search Dog, he MUST NEVER have been trained to locate any scent other than that of decomposed human tissue. .... but he has !

Enhanced training is intended to improve upon initial training, it's all training in the same area - recovery of dead human bodies. Enhanced doesn't mean different.

There is no opportunity to do that in the UK, only in the US. In the UK piglets are used. Later Eddie had some training using the actual scent of dead humans. This helped him to be absolutely sure what he was looking for, it wasn't training in a different area. These dogs are called different things by different people, but they are clearly trained to find, and used to find, dead bodies.

I now realise which article you're quoting from (I hadn't noticed that this thread had been resurrected).

http://www.csst.org/forensic_evidence_canines.html

That is one handler's classification of dog training and related terminology, but it doesn't appear to be universal.

Grime stated that Eddie was trained to find decomposing human remains and body fluids.

An area of confusion is what "decomposing human remains and body fluids" actually means. Dried blood from a living person is still a decomposing human body fluid. And we know that he reacts to that.

We don't know if he was trained to ignore urine, faeces, saliva, semen, etc. There is some ambiguity as to whether he reacted to semen / vaginal fluids on the Jersey sex tissues, or blood, or both.

Even if he did react to semen on the tissues, that doesn't mean that he was trained as a search and rescue dog (i.e. searching for missing living people, e.g., following a disaster), though, as that's a different specialisation. There could of course be some overlap if a VRD (victim remains dog, i.e., the more sensitive term for cadaver dog used by some handlers out of respect for victims' families) detected dried blood coming from rubble or whatever and the victim was still alive.

In disasters, they take in the S&R dogs first to search for anyone who may still be alive... then the VRDs go in to locate bodies for identification.

Personally, I tend to think that Eddie did react to semen / vaginal fluids on the tissues as he stated that the alert was within his training parameters. Keela was wheeled in aferwards and alerted to what was presumably blood. The ambiguity lies in whether he stated that before Keela was wheeled in or not.

In the winter of 1997 through to the spring of 1998 Dr. Deb Komar of the University of Alberta, Canada conducted a study 'The use of cadaver dogs in cases of advanced decomposition: A field study in adverse recovery scenarios and animal vs human scent discrimination'. Dr. Komar worked with cadaver dog teams from the RCMP Civilian Search Dog Program now the Canadian Search Dog Association [2] and the Search and Rescue Dog Association of Alberta.[3] This study showed the accuracy rates of cadaver dogs in moderate to adverse winter weather conditions, and also the dog's' capabilities to discriminate between animal and human remains. It indicated that an accuracy rate near 100% can be achieved through careful and directed training.

What the dog smelled: The science and mystery of cadaver dogs

Scientists still can't fully explain why some dogs are so effective at finding human remains
By Chris Oke, CBC News Posted: Jul 23, 2016

Dive teams spent 12 days searching the waters of Elliot Lake in northern Ontario and didn't find a thing.

When the cadaver dogs were called in, they needed just 15 minutes.

Six young people had been making their way home from a night of drinking on an island when their overloaded canoe capsized. Everyone made it back to shore, except for 20-year-old Vinnie Yeo.

One of the volunteers called in to help search for the body was Kim Cooper, a founding member of the Ottawa Valley Search and Rescue Dog Association, and the owner of two of the three cadaver dogs on the scene that July day in 1999.

Her Malinois named Piper was perched at the front of a boat as it slowly trolled the search area, sniffing at the water below. Fifteen minutes later, the dog turned to Cooper and let out a series of loud barks

Piper was the second dog to indicate in this spot.

The divers searched the area and found Yeo's backpack. The next day, they found a case of beer that had been in the canoe. The day after that, they found his body.

"It was quite a deep find," Cooper said. "Yet at the same time, the dogs were absolutely positive that they had him."

Not only can these dogs detect the scent of human remains under 30 metres of water, some can also detect traces as small as a shard of bone or drop of blood. They can also tell the difference between, say, a dead raccoon and a dead hiker.

And yet scientists still aren't 100 per cent sure how they do it and the training community is still figuring out how to train them most effectively.

'Body Farm'

"Most think an odour is just made of one chemical, when in reality it is made up of dozens or hundreds of chemicals," said Arpad Vass, a research scientist at the Oak Ridge National Laboratory in Tennessee.

Vass is a leading expert on decomposition odour analysis, and conducts his studies at the University of Tennessee's "Body Farm" — a research facility where human bodies are allowed to decompose in a variety of settings.

He still isn't completely sure why dogs are able to track decomposition scents so effectively. But in a recent paper he narrowed it down to a few organic compounds unique to humans that may offer possible explanations.

Mapping the hundreds of unique odours of human decomposition in all its stages could help with cadaver dog training and may even allow technology to replace cadaver dogs one day.

"The problem is only one of sensitivity," Vass said. "Canines, I'm pretty sure, are in the parts per trillion detection range and instruments are only reliable down to parts per billion."

Small number make the grade

Potential cadaver dogs start their training as young as eight weeks old and are usually certified at around two years old.

Breed isn't overly important. The dogs just need to be very energetic and very motivated to work for a reward. However, typical cadaver dog breeds are German shepherds, Malinois and Labrador retrievers.

Only fifteen dogs have qualified to work with the Ottawa Valley Search and Rescue Dog Association in the past 25 years.

Kim Cooper has personally trained five of them.

The most important part of the training is to expose the dogs to as many human remains as possible.

Cooper said human bones can be ordered off the internet from companies with names like Skulls Unlimited and The Bone Room. She occasionally gets access to the surface, be it a piece of carpet or some dirt, for example, on which a body was found.

But the most common training aid is placenta, donated by new moms.

"I'm in the habit of congratulating family members and in the second sentence saying, 'So, what are you doing with your placenta?" said Cooper, who has a few placentas in her freezer at home.

She said a handler will train a dog with the same odour source for approximately six months so the dog learns the subtle changes that take place during decomposition.

"It takes a little while to build up a solid stomach, so that you don't get too disgusted with what you're hauling around anymore," she said.

The pig problem

Mary Cablk of the Desert Research Institute in Reno, Nev., is in the unique position of being both a scientist and a cadaver dog trainer.

She conducted a study on the compounds of human decomposition compared to those of cows, pigs and chickens.

The smell of decomposing pigs was least similar to that of humans, which is a problem for cadaver dog trainers in the U.K., where it's illegal to possess human remains.

They'd been using pigs as training aids for years. But as Cablk points out, "If you have a dog trained on pigs, then you have a dog trained to find dead pigs."

Double blind

Such discoveries have played an important part in the ongoing professionalization of cadaver dog testing and training.

In 2011, Lisa Lit, a researcher at the University of California, Davis, found that what a handler already knows can affect the outcome of their dog's search.

The study was done using dogs trained to find drugs and explosives, but Cablk says the findings divided the cadaver dog community.

If handlers weren't using blind testing (where the handler doesn't know the location of the target scent) or double blind testing (where both the handler and test adjudicator don't know the target) then the dogs could simply be picking up on unconscious cues from the handler, not the scent itself.

"It's one of those things that, to a scientist, it makes perfect sense," Cablk said. "But dog handlers are not scientists."

Over the past five years, training bodies across North America have developed a more scientific approach to training and certification.

Piece of skull

In June, Kim Cooper took her cadaver dogs Breeze and Grief to Massachusetts to get re-certified with the North American Police Work Dog Association.

"We were very excited this year because one of the [training] aids was a piece of skull, so we got to work on a human skull," she said.

"Something new to put into our list of things that we've done."

I find it interesting as well.

This is one of the reasons why I find it misleading when some people keep referring to "cadaver" odour instead of "human decomposition" odour. Unless that person was congratulating family members on a still-born baby or deceased new mother, the scent is simply decomposing human material that doesn't necessarily mean that someone has died.

But the most common training aid is placenta, donated by new moms.

"I'm in the habit of congratulating family members and in the second sentence saying, 'So, what are you doing with your placenta?" said Cooper, who has a few placentas in her freezer at home.



And handler bias, intentional or unintentional, is an issue in crime scene investigations, particularly high-profile ones. Whether or not that potential bias is exacerbated in independent (as opposed to salaried police) handlers might make for an interesting study.

How true.    IMO no dog handler and his/her dog can be automatically regarded as ' exempt' from this possibility unless they have been previously tested.

IMO it has never been clearly established whether MG was a salaried employee of SYP during his time at PdL - or whether he was being employed as an 'independent' sub-contractor. 

The fact that unlike the other UK police dog handlers he never wore a police uniform and as far as I know was never referred to in any statements as DC Grime - and his dogs were never referred to as 'police' dogs (in the present tense) at the time  -  leads me to believe he was working independently  - and that this was his very first case  -which happened to seamlessly follow on from his departure from SYP.

(From memory so - if I've got an of that wrong - I'm sure someone will point it out)

There's an unresolved argument as to whether he was still technically on the police payroll or not at the time. Whether he was or he wasn't in that particular search, the fact still remains that his role in Jersey (not long afterwards) was NOT as a police handler, but as someone launching an independent career.

My comment isn't about him in particular, but about anyone embarking on a new career path and who needs positive PR to launch it.

There is no argument, the Chief Constable of SYP sent Grime to Portugal, he was not retired at that time.  As for cadaver dogs, it is very true, train a dog using decomposing pigs and he will alert to decomposing pigs.

Wednesday night, investigators, acting on a tip, descended on the building - one where the missing woman's husband had done some construction work. Inside, they found a wall that stood out from the others. A dog trained to detect cadavers became excited when he got near the wall, police said.

Yesterday morning, police were back in force.

By mid-afternoon, investigators knocked down the wall and removed a concrete block about 3 feet wide and about waist-high from a cubbyhole. They then called in firefighters, who cracked open the concrete with jackhammers and heavy blades and found the decomposing corpse inside.

The body was wrapped in duct tape and was covered with plastic and a canvas painter's tarp. The wrapped body had been encased in concrete, cinder block and construction debris.

"The body is wrapped up - can't identify if it's male or female, age, nothing," Bernardi said.

Nikki Burgess murder case

Later, cadaver dogs alerted detectives to that bathroom and the master bedroom. What the dogs alerted to was the presence of human decomposition.

“The first area they alerted to was in the master bedroom where the bundle of blankets was,” said Atkin. “The second area they alerted to was in the bathroom, specifically the bathtub.”

Blood-stained bedding, brass knuckles and empty bottles of cleaner were among the items recovered during a search the Hermitage home.

Cannon is charged with first-degree murder in the case. Burgess’ body has yet to be found.

http://wkrn.com/2015/11/24/man-charged-in-nikki-burgess-case-due-in-court/

He said Cannon told him he killed Burgess in her bedroom.

“He followed her to the bedroom, took out a pair of brass knuckles. The brass knuckles he said were wrapped in a piece of cloth or towel of some sort and he struck her in the back of the head the brass knuckle repeatedly until she fell on the ground in the bedroom,” Breuington testified.

He continued, “He took a cord that he had ripped off an appliance of some sort at the house – he didn’t say what appliance – he put it around her neck and strangled her to death.”

When asked if Cannon ever told him what happened to Burgess’ body, he said, “Took it to a farm, put it in a machine that ground up her body.”

Cadaver Dog Buster and the Black Dahlia Murder: The Scent of Death

Post by: sadie on May 23, 2017, 11:27:58 AM
Cadaver Dog Buster and the Black Dahlia Murder: The Scent of Death

The difference between the cadavar dogs, which you mention Pathfinder, and Eddie is that they only alert to Cadavar odour.  Whilst Eddie alerts to Cadavar odour and dessicated blood left by a living person. 

He was double trained to alert to both the scent of death and the sent of dessicated blood from a living person .. and will alert to both.  Most cadavar dogs will only alert to cadavar odour.


So if Eddie alerts, which is more likely?
That he is alerting to
1)  The dried blood from a living person?
or,
2)  the scent of a dead body?


As dessicated blood (from a living person) can come from such minor accidents as a cut finger.a picked spot, a grazed knee, menstrual blood, a nose bleed, then it would be surprising if Eddie had not alerted in 5A.  Madeleine arrived with a grazed knee


The incidence of the odour of a cadavar would be massively lower than the incidence of dried living blood.  Almost certainly Eddie alerted to dried living blood only.


Pathfinder, you cannot compare the alerts that Eddie made to those of a dog trained only on cadavar odour, unless you mention that Eddie also alerts to dried living blood.  It is not honest to do so, because of this.  IMO

All cadaver dogs alert to blood including Buster. Don't be ignorant Sadie.

“Buster” World Famous Police Cadaver Dog Dies from Sudden Heart Attack

Buster, who was 12-years old (85 in human years)  was a court-certified HRDC expert witness.  His official title, being a Human Remains Detection Canine, more commonly known in police  jargon as, a “Cadaver Dog.” Buster, known as, “The Wonder Dog” did not have just your average nose for his work, but was truly one of the Top Dog’s in his field.

A world traveler Buster’s search assignments included detecting human remains and locating lost gravesites of  WWII MIA’s in Europe (Normandy, France,) as well as Belgium (Battle of the Bulge 1944). Buster has made numerous trips to the Pacific to the small atoll of Tarawa, in the Gilbert Islands, where he has been credited with finding dozens of MIA remains.

Buster also conducted follow-up investigative searches in the Charles Manson Case at Barker Ranch and in my own Black Dahlia investigation in 2012 and 2013. His most recent work involved locating and “alerting” to human remains in a Northern California unsolved murder investigation.

The ignorance is all yours, Pathfinder.

No clue about Buster, but a cadaver dog will react to blood, as a discrete scent, if introduced to blood as a discrete scent and rewarded for doing so.

If you skip that step the dog won't react to blood as a discrete scent.

"The dog can detect things you can't see, even if it's a crime scene where someone had cleaned up blood. If there's a drop of blood that's been wiped up and you can't see it, the dog will find that. Then you bring in your forensic staff and let them concentrate on that spot so they can quickly determine if there's blood evidence in the house."

K9 CRIME-FIGHTER: BUSTER THE 3-LEGGED DOG FINDS BURIED BODIES
https://crimewatchdaily.com/videos/0-dmok8ljg/

Start from the premise that all dogs detect all scents, all the time.

What a dog reacts to is determined by training.

All dogs detect the scent of drugs.

But only dogs trained to react to the scent of drugs will do so.

All dogs detect the scent of cancer-cells in humans.

But only dogs trained to react to the scent of cancer-cells in humans will do so.

All dogs detect the scent of money.  But only dogs trained to react to that scent will do so.

And so on.

Eddie would react to the scent of blood, because he was introduced to blood as a discrete scent and rewarded for doing so.

When Keela, the younger of the two dogs Eddie-and-Keela, came along, she was trained to react, only, to human blood.

It was always the weak link in the Eddie-and-Keela partnership that both dogs react(ed) to the scent of blood.

When Grime trained Morse, he skipped the step of introducing Morse to the scent of blood as a discrete scent, so that the dog would only react to blood if it was mixed with a human corpse which, alone, is what he was trained to react to. 

The idea was that by not training the dog to react to blood as a discrete scent you would increase assurity that if the dog did react, the reaction was to a cadaver scent.

At the same time, in the event of a reaction by the cadaver dog, you had a second dog trained to find nothing but blood who could search an area made manageable to search by the reaction of the cadaver dog looking for blood (that may be of assistance in a criminal enquiry).

And if the lower part of the cadavar where the blood has settled, has been damaged as it is moved etc., it will bleed Cadavar blood according to one article I read.

So Cadavars do sometimes lose blood.  A cadavar dog will alert to this, even if the blood has been cleaned up.

To get any dog to alert to anything, you have to introduce the dog to the scent you want the dog to alert to and reward the dog for alerting.

If you don't want a dog to alert to that scent, you simply skip the step of introducing the dog to the scent and rewarding the dog for alerting to it.

Then the dog won't.

Having two dogs that both alert to the same scent is, well, plain barking.

Always the weak link in the Eddie-and-Keela combination.

There was always a weak link with Eddie.  He was trained in one way, and then expected to understand another.  And Martin Grime did know this.

This, I think, is a useful link.

It seems Australia has followed the American lead in allowing an American-style 'bodyfarm'.

http://www.dogforceaustralia.com.au/police-dog-handler-detection/

Its course on cadaver dog-training lists these components of training:

Quote
Cadaver (Human Remains) Detection Dogs will be fully accredited on the following odours:

human tissue (in varying states of decomposition)
blood
bone

Note that human tissue, bone and blood are all listed separately.

The process of teaching a dog to react to, distinct from detecting (which it does, automatically and instinctively without training) the odour of blood is a separate and distinct step that the dog must be taught.

If you don't teach the dog that step, then, while the dog will of course, still detect the scent of blood, the dog won't react to it unless it is mixed with something else the dog is taught to react to.

Cadaver dogs led them to the spot on the 90-acre farm in Solebury Township where they discovered human remains inside a 12ft-deep common grave.

“I don’t understand the science behind it, but those dogs could smell these poor boys 12-and-a-half-feet below the ground,” the Bucks County district attorney Matthew Weintraub said at a midnight news conference.

Searching for vulnerable people who have wandered off and get lost as a result is one of the tasks undertaken on a regular basis by police search and rescue and cadaver dogs.

I've never heard of it before but like all the best ideas storing scent for emergency use is just so logical it is amazing we don't do it as a matter of course.  It should work for children and although in a domestic setting there should be plenty of trace around it could be almost guaranteed to be specific if isolated in a bottle.

Manufacturers say they work better and more quickly than articles of clothing, because they are not contaminated by other people's smells or smells from the environment.

Whilst searching for some answers to a particular live-scent dog related issue, I came across an interesting case in the USA which has historical parallels to the McCann case (dog alerts, eye-witness testimony & partial tangible evidence match) - State of Florida v Wilton Dedge.
http://scholarship.law.upenn.edu/cgi/viewcontent.cgi?article=1092&context=jlasc

It's a long read but well worth the time spent when considering scent dog evidence, handler claims & also eye witness testimony.

Wilton Dedge was the accused, Ms. Smith the rape victim.

*snipped*
The only other “evidence” that the police were able to develop before trial involved the
use of a scent dog months after the crime. In March 1982, Dedge wet his hands in the Brevard
County Courthouse bathroom, dried them on paper towels from a bathroom dispenser, and handed
the paper towels to an investigator. The investigator grasped the paper towels by the edges, hung
them to dry, and then placed them in a paper bag from a coffee shop in the building.34 Eight days
later, police dog handler John Preston and his German shepherd, Harrass II, conducted a “scent
lineup” using the sheets from Ms. Smith’s bedroom and four dirty sheets from the local jail that
Dedge had never touched. Harrass II sniffed the dried, eight-day-old paper towels in the bag and
Preston walked the canine up and down the lineup of sheets, commanding him to “search.” On the
second pass, Harrass II stopped at the (bloody) sheet from Ms. Smith’s bed, allegedly detecting
Mr. Dedge’s scent on the sheet—more than three months after the crime. Harrass II was later brought to Ms. Smith’s home, where he supposedly indicated Dedge’s presence more than three
months earlier by touching his nose to various areas in the house.
The trial began in September 1982 and lasted eight days. The State relied upon three
things to prove Dedge’s guilt  1) the eyewitness testimony of Ms. Smith; 2) the hair analysis; and
3) the dog scent lineup.

Dedge was found guilty & had his sentence increased to life after a prison inmate falsely snitched to obtain a reduced sentence for himself.
To cut a long story short, Dedge was eventually cleared years & multiple appeals later, after 2 sets of DNA tests were carried out on semen traces collected from the victim at the time.
The dog handler in question, John Preston, was later discredited but reportedly helped secure convictions in around 100 cases across the US. https://en.wikipedia.org/wiki/John_Preston_(dog_handler)

It poses the question to the Dogs Don't Lie Brigade - was the handler to blame, or the dog, for all the false alerts?

Yet the Portuguese court said it was a fact the dogs had alerted to cadaver scent and we know what that would have meant for the McCanns had they ever been prosecuted.
Dredge was convicted on the basis of incorrect identification by a witness - the actual victim (think Martin Smith), the hair which was very similar to Dredge's & would not rule him out as the attacker (think 15/19 alleles) & the dog alerts which placed him at the crime scene.  If an American jury could be fooled (many times over in Preston's case) so could a smaller number of Portuguese jurors.

We live in Lagos district.  The patron saint of Lagos, and of Algarve fishermen, is St Gonçalo. The hospital in Lagos is named after St Gonçalo. The school that two of our grandchildren go to in Luz is the College of St Gonçalo.

I wanted a Portuguese name, and one that is not common here. So Gonçalo he is.

Our grandchildren got it straight away.  It takes oldies a little bit longer.

I don't have a problem with this, in fact I think it's a really good name for a dog. I might even use it myself next time around, and if it's the year of G in France

Having done a quick search in a Catholic saints index,  there doesn't appear to be a Saint Goncalo.
There is a Blessed Goncalo with a date of his beatification but no mention of a canonisation.

There are at least 2 St Gonçalos.  One appears to be the major one, and is popular in Brazil.  The other appears to be the lesser one, and is associated with Lagos.  That's 'our' one.

K9 that found missing California man, who was found dead in WNY, was on first career search

The cadaver K9 that found him is a German Shepard, Malinois mix. Her name is Leiche; she's with the Erie County Sheriff's Office. She came to the department with zero cadaver K9 training, less than a year ago.

Seven days a week, she trains with her handler, Erie County Sheriff's Deputy Bradley Girdler.

"Every day I do put out some hides for her to find," he said during an interview with News 4 at Chestnut Ridge Park.

Leiche looks for the smell of decomposition.

"She doesn't actually track anyone... she doesn't get a piece of clothing or anything from a specific individual, she would just go and detect that scent."

If she finds that scent, she sits.

"She doesn't know what she's finding, she just knows the scent she finds is ultimately going to give her a reward, which is hot dogs and a ball."

Back in May, Rudy Ray Rockett had been missing almost three weeks. Search crews scoured areas they thought he could've been, but all of them came back with no leads.

That all changed the night of May 19. This Erie County Sheriff's duo was called in, on their very first 'real' search.

"On the way to the search, I was nervous about how she would do, how she would react under real-world conditions," Girdler said.

They were called to an East Otto address.

"We went down there, it was dark."

They searched an open camping area, but Leiche didn't find anything there, so they expanded their search area.

The two, along with a Cattaragus County Sheriff's deputy, went down a hill, through a pine forest. Her nose led them through a clearing where there was a ravine with a creek running through it. Along that ravine, she sat.

"It's pitch black and my flashlight is on her," Deputy Girdler said. "So I'm walking through and I'm literally just shining my flashlight on her to watch her body language and movement, and then when she sat, I initially didn't realize why. But then as soon as I moved my flashlight across my feet, I realized she had in fact sat right next to Mr. Rockett."

Twenty days after he went missing, Mr. Rockett's family could finally get some closure.

Just seven months after starting on the job, Leiche had her very first find.

"I was absolutely proud of her," Deputy Girdler said. "Obviously it's a difficult situation, but for her, that's her job, so when she did her job correctly, I was obviously delighted with her."

I think 'false alerts' may be a misnomer.  The dog alerted to something but what that something was is not open to interpretation - forensics make that decision; in the hire car the forensics indicated it was cellular material on a key fob.

Unless you can provide a cite consisting of independently assessed training data your 'best dogs' claim is unsafe and merely a matter of your opinion.

Blind faith in their ability just doesn't cut the mustard.
There are stringent procedures in place in American courts regarding training protocols for these dogs.  Rather like calibrating an instrument to ensure it is fit for purpose.

There are stringent procedures in place in American courts regarding training protocols for these dogs.  Rather like calibrating an instrument to ensure it is fit for purpose.

You have not provided a citation outlining Eddie's accredited training schedule and his performance in training.

That’s a new one, Eddie was wrong because he didn’t have a piece of paper...

It seems that with or without a piece of paper the attributes of cadaver dogs are not an exact science.  If they are to be taken seriously in a court of law there has to be a more consistent regime of training standards which are accredited independently.

In my opinion what happened in Praia da Luz is a prime example of the concern that they have "the potential to cause complications in an inquiry".

Who knows what Shannon's fate would have been had the police relied on the cadaver alerts and stopped looking for her.  As it was she was found alive and as well as could be expected.

Who knows what would have happened in Madeleine's case had the police not been beguiled by the pseudo science they apparently believed of the dogs to stop looking for her.
As it is ~ Madeleine is still missing.


Sniffer Dogs 'Can Hinder Police Work'
00:43, UK, Thursday 24 March 2011
By Gerard Tubb, Sky News correspondent
(http://www.gerrymccannsblogs.co.uk/press/47march11/sky-25-3-11-eddie_small.jpg)
Sniffer dog Eddie was relieved of his police duties

Police sniffer dogs used to find missing people and dead bodies "urgently" need better training and monitoring, according to an official report.

The Government's National Policing Improvement Agency (NPIA) said specialist victim recovery dogs are not trained to approved standards, with no way of gauging their competence.


The NPIA reviewed the use of the specialist sniffer dogs two years ago, but its report has only now surfaced following a request by Sky News.

"There is no consistency in what the dogs can do and how it is done," the report states.

"Furthermore, there is no national standard for accrediting dogs and handlers or record keeping of the success rate they achieve."

The report added the dogs, which are trained to detect the smell of dead bodies, have "the potential to cause complications in an inquiry".

"There is an urgent need to have national policy on their training, accreditation and deployment," it concluded.

The review uses a kidnap investigation to highlight how dogs have tied up valuable police time.

The animals detected human remains in old furniture that had been bought from houses where the owner had died.

The use of victim recovery, or cadaver dogs, has proved to be controversial in a number of high-profile cases in recent years.

A South Yorkshire Police spaniel called Eddie was said to have sniffed out the "scent of death" at the Haut de la Garenne children's home in Jersey and the apartment from which Madeleine McCann disappeared in Portugal.

But in both cases nothing more was found and South Yorkshire Police say Eddie is no longer working with them.

Victim recovery dogs from four different police forces were used during searches for kidnapped schoolgirl Shannon Matthews in Dewsbury in West Yorkshire in 2008.

The dogs found evidence of dead bodies, but officers later discovered the corpses were nothing to do with her disappearance.

"The properties searched contained a high level of second-hand furniture bought from dwellings where someone had died," according to the NPIA report.

"This resulted in numerous indications that required further investigation to confirm whether they were connected to the investigation, or to previous owners of the furniture."

The Association of Chief Police Officers told Sky News it was consulting individual police forces and hoped to have national training standards for the dogs later this year.

Is this the truth of the matter?  Was Eddie relieved of his police duties ?
I think it is just a bit of editor's hyperbole, Sadie, and I swithered before copying it in.  Martin Grime reached retiral and was able to take Eddie with him.

This wasn't one alert by Eddie but many alerts. You really think the police who know Eddie believe he false alerted many times to apartment 5A, clothes with no blood, outside of the car etc.  It's not hard to work out why so much money is being spent on this case.

He alerted spectacularly at the hire car.  One of the areas for which we do have forensic confirmations.  Not a single one of which related to Madeleine as an individual either alive or dead.
Therefore - all false positives.

He alerted to some clothes in the gymnasium all from the same cardboard box.  These were the clothes present in the villa which he had previously studiously ignored.
More false positives?

The McCanns were made arguidos on the strength of the dog alerts!  They were neither arrested or charged because there was no supporting evidence to do so.
Work that one out.

Eddie alerted in the Parker case - September 2007 i.e. a month after the Madeleine McCann case alerts.

July 2009
We also saw video played in the courtroom to demonstrate how another dog, Eddie, found a sample pair of pants hidden in the Walker County Jail that was perfumed with a cadaver scent. Eddie is an English Springer Spaniel belonging to Martin Grime, a world-renown forensic K-9 expert based in the United Kingdom.

Grime testified he was paid $450 a day, plus travel and living expenses, by the FBI to search some areas in Walker County in connection with Teresa Parker's disappearance.

During a visit to Parker's home back in September 2007 Grime said he and Eddie sniffed around their garage.

"He immediately gave a positive bark response within the garage between a truck parked to the left of the entrance and a boat parked to the right," Grime said.

Grime added Eddie did not seem interested in the vehicles but in a scent that was wafting in the air, based on the way the dog held his nose upward. Grime said Eddie then "hit" on an abandoned house next door. Testimony shows that house was never repaired after a fire gutted the inside and killed a child several years ago.

During lengthy cross-examination Grime said there is no evidence to show Eddie smelled anything incriminating against or linked to Mr. Parker. Like Higgins, Grime said cadaver dogs can only prove useful when there is other evidence that corroborates the dog's "hits."

The FBI has a keen interest in the outcome of this case. If Parker is convicted the case could pave the legal way for future prosecutions where there is no evidence other than dog "hits" in connection with a person accused of murder.

Thursday, September 3, 2009

A criminal court jury on Thursday afternoon found former LaFayette Police sergeant Sam Parker guilty of murder.

He was sentenced to life in prison by Judge Jon "Bo" Wood.

Parker also received two concurrent five-year terms for violating his oath of office and giving a false statement.

He was found not guilty of computer invasion of privacy.

The jury from Bartow County deliberated for 23 hours over four days.

Parker was found guilty of the slaying of his wife, Theresa, whose body has never been found. She was last seen March 21, 2007.

From section 6

The fact is that Mr Grime was not, at the time he was deployed in Jersey, an ACPO accredited police dog instructor, despite his claims to be so in statements and other documents submitted during his involvement in Operation Rectangle. Furthermore, the licence for his cadaver dog had expired some seven months prior to his arrival on the Island and the licence for his human blood detection dog expired in March 2008, whilst he was deployed in Jersey and using that dog. According to the ACPO Police Dog Working Group, “Dog and handler teams that, for whatever reason, fail to remain in-licence [are] deemed “not competent” for operational duty until such time as they [have] successfully undergone a re-licensing process”. Mr Grime has advised that his dogs are licensed by a suitably qualified person, although no further details have been provided to us.

Also taken from the same document & imo the most potentially explosive piece of information in the report......


It was not until 25 March 2008, thirty seven days into his
deployment, that a draft written contract was sent via e-mail by Mr
Grime to FSM Coupland. This document (i) omitted the dates of
agreed deployment; (ii) stated that remuneration for the first five
days of the deployment would be £750 per day and £600 per day
thereafter – although a subsequent clause stated that non-UK
mainland daily rates would be negotiated separately; (iii) stated
that the copyright of ‘all data and information provided’ would rest
with the ‘Chief Constable of Greater Manchester Police’ (sic);
and
(iv) was never signed either by Mr Grime or by a representative of
the States of Jersey Police.


 The CC of GMP was found dead less than 2 weeks before that email was written ("suicide").
Why would a CC, unconnected to the Jersey case, allegedly want copyright of all the data Grime gathered??

Well found misty. 

So it seems

1.  Grime was not presenting the facts fully.  Eddie was not an ACPO accredited police dog instructor, but he presented that as fact, didn't he?  8)-)))

2.   Further more, he advised that his dogs were at the time licensed by a suitably qualified person, but he never provided any further details

3.   According to the ACPO Police Dog Working Group, “Dog and handler teams that, for whatever  reason, fail to remain in-licence [are] deemed “not competent” for
operational duty until such time as they [have] successfully
undergone a re-licensing process”. 
 
Was he still in license in Pdl ?  or should he have successfully taken a re-licensing process to ensure his team were competent?



What do posters think of all that?

Were these buried? Cite.

There are thousands of examples;  from whole bodies to body parts;  from newly dead to historic bones;  to buried or exposed.

But the fact remains that dog walkers and their dogs are responsible for finding them.

It is a difficult one, John.
I doubt there is anyone who is unaware in general of the tremendous value of working dogs in every walk of life and recognises their excellence whatever they are trained to do.  The difficulty lies in the particular of Madeleine McCann's case compounded immediately thereafter with the Jersey fiasco.

The Nose Knows

Can cadaver dogs really sniff out 30-year-old remains?

By Katy Waldman

Police on Thursday revived their search for Etan Patz, a 6-year-old who disappeared in 1979 en route to a New York City bus stop, after a cadaver-sniffing dog recently detected the odor of human remains in a basement near Patz’s SoHo home. Can dogs really smell 33-year-old remains?

Yes, if you have the right dog.

How Swedish dogs helped cross-border Kim Wall investigation

Danish artist-inventor Peter Madsen was charged on Tuesday with murdering Kim Wall on board his submarine. The policeman running the Swedish side of the investigation explains the crucial role of his officers – and their dogs.

Peter Madsen's explanation of what happened onboard the submarine Nautilus is crumbling.

Just over a week ago, more remains are found that, according to Danish police, disprove Madsen's version of how the Swedish journalist Kim Wall died.

The proof could be secured after Swedish, specially trained criminal search dogs assisted the Danish police in the search.

Dog hander Johan Esbjörnsson describes the assignment as unusual in several ways.

"It was very special to work at sea. Even the case as such. It felt good to be able to contribute."

(https://e.cdn-expressen.se/images/e5/d9/e5d9b7ddf9014e29a805beb9acb1bc09/annan/632@60.jpg)

Ben is seven years old and the black-brown Springer Spaniel has been waiting in the car while Johan Esbjörnsson showed around the farm.

- He's amazing. He is always happy to work.

Johan Esbjörnsson has worked as a police officer for 40 years, 28 of them as a dog handler. Over the last five years, he and Ben have been a team. Just this windy day, the team is busy preparing for a planned search the following week. And with training Ben in tracking.

When a person dies, the process of decay begins almost immediately. Within 30 minutes, the body has begun to break down, a process that starts in the stomach. During the trash, the cadaver is formed, a smelly fluid that leaves the body.

It's the fluid the dogs are tracking.

The Swedish criminals seek dogs also have a special knowledge: they are trained to search in water.

Already the week after Kim Wall's disappearance, Danish police contact their colleagues in Sweden. The Copenhagen police have confirmed that it is assumed that Kim Wall is dead and looking for a body. Most likely, the body is in the water and now the Swedish police are advised to assist with their dogs, which, unlike the Danish criminals, are trained to search for dead people in water.

The dog handler Lars-Göran Eriksson and the labrador Ace from Stockholm are one of the two teams who first go to Denmark, the first time they are going to search for a dead person at sea.

Searching at sea is basically no different to searching on land: what the dog is looking for is a cadaver, a smelly fluid that leaves the body - and the interaction between dog and driver is crucial.

The searches for Kim Wall were focused on Kögebukten

The Swedish dogs are certainly trained to seek water, but they are used to searching for smaller lakes.

The gases that leave a dead body should be transported through water. And in the water there are several layers, some of which do not let go through the gas. And then the gas moves with the currents, until it for some reason moves on to the surface. It can be a good bit, it is due to ebb and river and cold and other factors.

"If we are looking for a lake in the Stockholm area, it's a lake of maybe 400 times 1,000 meters, so we can not miss that much, the gas goes straight and the find is often straight down," says Lars-Göran Eriksson.

The search for Kim Wall is based on the supposed route the submarine traveled during the night when the Swedish journalist disappeared. The focus is on Kögebukten, where Madsen's submarine also dropped.

The work is carried out under difficult conditions.

- We had no reference points except the digital chart. In some days it was also very high lake. We had no previous experience of it, "says Lars-Göran Eriksson.

When searching at sea and on land, dogs are looking for the same odour. What is different between the two search environments is working conditions, conditions that place extremely high demands on the dog's character.

"It's also possible if the dog can go on a boat, we have had dogs who can not handle it. It must also be a dog that is calm and stable."

Complicated communication

Another aspect of the work that is complicated by sea is the communication between the dog and the handler. In most cases, out in terrain or in an apartment, the dog marks a bargain by basically laying the nose in the spot where it marks a bargain. For natural reasons, it's not possible when you're out at sea.

"Most dogs are barking. My dog hurts more and almost wants to jump in. Then you know he found something, says Lars-Göran Eriksson.

As a last and definitive piece, divers have the Danish Armed Forces gone down and searched where the dogs are marked.

On Saturday, October 7, the Danish police confirm that new discoveries were linked to Kim Wall. Her head and legs have been found together with clothes and a knife.

The findings have been made after the Swedish special search dogs have selected at certain locations in Kögebukten.

- It's Kim Wall's head that's found. The head was in a bag, and the bag also contained metal pieces, Jens Möller, chief of the murder unit at the Copenhagen Police, told a press meeting in connection with the finding.

The specific findings made in Kögebukten, with the help of the Swedish dogs Ben and Ace, are seen as particularly important, especially when it comes to determining the cause of death.

Until the last finds of Kim Wall's remains, Peter Madsen has responded to the police's questions during interrogation. The only defense attorney, Betina Hald Engmark, Madsen has been determined to collaborate and during arrest talks he has published the text about himself, his projects and his version of the trip that ended with Kim Wall's death.

But after the latest finds in Kögebukten, Peter Madsen is silent. Suddenly he no longer wants to talk to the police or answer questions.

Madsen is now undergoing a legal psychiatric investigation, which is expected to be ready towards New Year. Everything indicates that in the near future he will be prosecuted for killing and killing Kim Wall.

When the rain begins to fall over the gym outside Lund on the windy day in October, it has been a few weeks since Johan Esbjörnsson and Ben came back from the searches in Kögebukten. In the garage, the team's boats, those used in Denmark, are on trailers.

Now it's back everyday, and that means training.

(https://f.cdn-expressen.se/images/f2/bd/f2bd737d8b304e5c978bd3f4cda30c46/annan/632@60.jpg)

After just a few minutes, Ben has found what he seeks: with one's mind he is lying on the ground, quite still, with the nose pointing at one point.

Johan Esbjörnsson marks the finding with a bright colored marker and had it been sharp - at a place where a suspected sexual offense was committed, it had now been time for the police's technicians to accept and secure the evidence.

As a dog handler in Polisregion South, Johan Esbjörnsson usually works in civilian clothes, it becomes easier and many people appreciate low profile, he says.

When the other colleagues from the dog training center outside Lund are looking for drugs, weapons or banknotes, Johan and Ben are looking for dead people. People who may have been subjected to a serious violent crime. It places high demands on how they occur.

Why do you think a body would still be there? Only a complete idiot perp would leave a body in a basement to be found.

"Hernandez, a 51-year-old man with no formal criminal history, said he had lured Etan to the bodega’s basement with the promise of a soda, instantly choked him, placed him, still alive, in a plastic bag, and then inside a cardboard box, threw the boy’s book bag behind a freezer and carried the box in broad daylight several blocks before placing it on the sidewalk. He said he had not known the boy, and he offered no motive."

From above article:

When a person dies, the process of decay begins almost immediately. Within 30 minutes, the body has begun to break down, a process that starts in the stomach. During the process, cadaverine is formed, a smelly fluid that leaves the body.

It's the fluid the dogs are tracking.

"Further searches identified a location where the E.V.R.D. alerted in the front bedroom of the offenders empty next door dwelling house. When interviewed the suspect admitted that the body had lain in the room for 1 hour prior to disposal. Forensic teams were unable to extract any forensic evidence despite being shown the exact position."

Pedro Hernandez Gets 25 Years to Life in Murder of Etan Patz

Mr. Patz turned toward Mr. Hernandez and said: “Pedro Hernandez, after all these years, we finally know what dark secret you had locked in your heart. You took our precious child and threw him in the garbage. I will never forgive you. The God you pray to will never forgive you.”

After a long day of interrogation in May 2012, he told detectives in a videotaped interview that he had met Etan outside the bodega and lured him into the basement with the promise of soda. There, he said, he choked the boy. He later repeated the story to a prosecutor during a longer interview, which was also recorded.

“I just couldn’t let go,” Mr. Hernandez said in one interview. “I felt like something just took over me.”

Mr. Hernandez said he put Etan inside a plastic bag and then inside a box and left him a block away in an alleyway with some trash. He said the child was still alive when he abandoned him. He also denied that he had sexually abused Etan.

Mr. Hernandez’s lawyers presented evidence that he had a low IQ as well as schizotypal personality disorder, which caused him to mingle fact and fiction. His daughter testified that he sometimes hallucinated about demons and an angelic woman dressed in white.

The prosecution team — Joan Illuzzi, Joel J. Seidemann and James Vinocur — introduced witnesses who said that Mr. Hernandez had made a similar confession to people at a prayer retreat shortly after Etan disappeared. In addition, his former wife and a childhood friend testified that Mr. Hernandez had told them in the early 1980s that he had killed a boy in New York City, although he gave different details.

You can put a living person into a box "alive" but unless there is sufficient oxygen that person is not going to stay alive for long.  Once that formerly living person dies then cadaver odours would develop.  Thinking about it by dying in such a fashion, the body temperature would be up and the insulation provided by the box would cause rapid decomposition of the body (i.e. comparatively  rapid cadaver odour development would be the outcome) IMO.

Dogs are regularly tested and if they fail they are out. They would trust a professional dog alert that corroborates with other evidence over a lying murderer. The dog in the Zapata case also alerted 25 years later to cadaver scent. These are not strange coincidences but dog's doing their job right.

In the confession it said "Pedro Hernandez, a former bodega stock clerk who confessed to luring 6-year-old Etan Patz into a basement and attacking him, ..."  So if in that attack EP bled onto the floor of the basement and that blood decomposed after it soaked into the woodwork (say) that could be the source of the cadaver odour in the basement even though the child is said to be still alive in the box out on the pavement.

But according to my understanding, Rob, that is not correct.

That would be blood from a living person that had since dried.  There would be no cadavar odour in that blood even later.  A blood dog might have alerted to it, but not a Cadavar dog.

Please correct me, if I am wrong.

I am certain you are wrong Sadie. Blood split could dry on a surface.  It would have to be a thin layer but if it got into a crevice between floor boards or tiles it would be unable to dry and it could go rotten.
