Are Victim Detection and Forensic Evidence Search Dogs reliable?

Or a shedful of posts accusing Sally Richards and David Brake of "cueing" their dogs if it goes the other way.

Just to avoid confusion, ci (pronounced key) is Welsh for dog and not a command to cue in an accent

If the deployment of the dogs does not advance the investigation, we simply won't hear about their role.

the minute he walked into 5a

"85 minutes, or 150 to 180 minutes?: That is the question", as Hamlet might have said.
In other words, which of the two results of the CSST experiment is relevant to this case?
And it is Eddie's reported interest already before entering, that provides the answer, which figure to use.

The decomposition process has to have started to leave cadaverine.

Specifically the acids in the gut have to eat through the intestines which produces the gas which is cadaverine.

This takes at least an hour usually two to begin but is affected by ambient temperature.

Appreciating the difference between cadaverine and cadaver odour might be a useful start ...

Contaminated items brought back to the apartment would have given the same result.  As Mr Grime stated, the alerts could very well have arisen from cross contamination.

A little bit of information in regard to the vehicle searches in the underground garage. The garage was 'swept' by the dogs prior to the cars being brought in resulting in zero alerts.  We all know what happened next.  Eddie reacted to the odour emanating from the Scenic and not the wall.

The dogs have become so reliable that they are now being used to detect diseases in humans.

How Man's Best Friend Can Detect Disease.

The use of dogs in medicine could lead to improved detection rates of disease and a better quality of life for sufferers, according to a charity.




 Medical Detection Dogs trains canines to smell the odours that diseases like cancer and diabetes give off in sick patients.

 The charity says some of its dogs can now detect disease with 93% accuracy and the organisation regularly receives samples from consultants wanting another way of testing.

 Dogs are also being trained to look after sufferers of narcolepsy and for one patient this has changed her life.

 Kelly Sears is one of 31,000 narcoleptics in the UK.

 She falls asleep without warning in sometimes dangerous places but says that with her specially trained dog Theo, life is much better.

 The dog can smell the chemical changes in her body and warn her if she is going to fall.

 If she falls, he rushes to her side to wake her up with nudges and licks.

 Ms Sears told Sky News: "Before Theo I didn't go out on my own ever.

 "With Theo, if I go out shopping with him and I fall, then he'll just nudge and bark until I wake up.

 "Other people around me will quite often stop and watch and say to me: 'I didn't want to disturb you as he looked like he knew what he was doing.'"

 Dr Claire Guest, chief executive of Medical Detection Dogs, said the use of dogs in medicine is becoming more common.

 She said: "It's taken some time to get over the scepticism.

 "This is an evidence-based work we've published in a number of journals and it's now proven that disease does have an odour.

 "Dogs can be used in a whole variety of ways to warn us when these odours occur."

 Dr Guest says some consultants are sending her samples of their patients on a regular basis. She hopes this will become a normal part of disease detection and patient assistance in the future.

 "How we've missed this for so long without knowing that there are dogs around us that can do this is quite incredible," she added.

 "It's a new, non-invasive way of keeping people safe."

Other organisations like Support Dogs have established the use of canines in helping epileptics, those with autism and physical disabilities.

Sweeping the area beforehand was a waste of time.

There was an innocent scent in the Renault Eddie reacted to, spots of Gerry's blood.

There might easily have been innocent scents in any of the other 9 cars.

In the inspection at the gym, there was, apparently, a prior sweep of the area by the dogs to rule out prior scents.

But there was also no gap between completion of the reconnoitre and commencement of the search, suggesting that the clothes were laid out before the reconnoitre.

So what was the point of the reconnoitre?

And why wasn't any scent detected during the reconnoitre?

ETA: after both inspections at the villa and at the gym, Harrison gave PJ personnel translated NPIA instructions on how to conduct inspections in buildings and in cars.

My money is firmly on  the PJ cribbing from these instructions.

Yes, and thankfully none of the patients are going to claim the results are false because the handler was cueing the dog.

[ferryman]

Possibly the oddest accusation against Mr Grime so far.

The facts are recorded in the files.

[ferryman]

I actually am willing to countenance that if the 10 cars had been lined up with an 11th that was a hearse, Eddie would have picked the hearse, with little or no prompting or guidance from Grime.

But then, that brings us back to questions put to Grime in his rogatory interview about whether Eddie differentiates between strong or weak sense.

Grime's answer was that Eddie doesn't!

He simply recognises a scent he is trained to detect and reacts.

So why all the galloping around and prompting before each reaction?

[Brietta]

Given that you are such a self appointed expert on cadaver dog handling, how EXACTLY did Grime prompt and cue Eddie? Given your claim this one should be very easy for you to answer.

Clever Hans?

Which may be why two handlers are working at present.

[jassi]

Maybe each handler only has one dog. Will dogs work with other than their own handler?
