Title: Could the alerts in 5a have been caused by previous CSI chemicals?
Post by: Brietta on August 14, 2018, 09:59:20 AM
I still think that Eddie was influenced by something to alert as he did in apartment 5A and all I can think of are scents left by the previous investigation which used substances with which he was likely to be familiar and 5A the only place which had been treated with them.

That is only your thoughts.

Going back to basics - it wasn't a 100% nothing... found in there. 5A

That is why were here today - imo something was found.

Yet nothing - nothing 100% nothing was found in any other apartment.

Surely Murat’s villa would have been contaminated with the same scents as it was forensically examined too. Did Eddie alert in Murat’s villa ?

That's an interesting observation Brietta and would explain the alerts in 5a but not elsewhere. It would be interesting to know if any of the chemicals used by CSI have an impact on these dogs. Maybe someone has come across this previously.

Did Grime or Harrison ever make reference to this possibility in any of their conclusions because if they didn't I feel that was a serious ommission.

Wasn't it noted by Grime that the effects of masking are minimised.  The police would know if chemicals used by the police routinely prevented a cadaver dog from doing its job.

"The dogs' passive CSI alert provides an indication as per their training and does not vary. They only give an alert when they are 'positive' that the target of the odour is present and immediately accessible. If they had any doubts they would not give an alert. EVRD gives an alert by means of a vocal bark. The variations in the vocal alert can be explained by many reasons such as 'thirst' or 'lack of air due to effort'. Every alert can be subject to interpretation, it has to be confirmed. The signals of an alert are only just that. Once the alert has been given by the dog, it is up to the investigator/forensic scientist to locate, identify and scientifically provide the evidence of DNA, etc. " http://www.mccannpjfiles.co.uk/PJ/MARTIN_GRIMES_RIGATORY.htm

Still there was nothing to ‘misinterpret’ with Murat because there were no alerts....even though that forensic fluid used in apartment 5a had been used there too.

One might well presume a forensic team visited the Murat residence to collect samples and in the process use substances for detecting blood ... but I am afraid it requires a cite to substantiate that presumption.

With respect ... your cite mentions nothing about searching for blood using a substance such as ~ "Kastle-Mayer" peroxide test ~ which means it is not a valid cite.
Which in my opinion makes your following sentence ... just as your first was ... inaccurate and misleading.

I don't know what you mean by 'treated with them'. As I understand it the only substance which would have come into contact with any part of the apartment would have been distilled water used to moisten a swab. The swab would then be tested with the substances, not the source stain.

As well as the dragon's blood used in the search for usable fingerprints ... chemicals for the detection of blood were also used

Snip
Also, innumerable tracks [footprints] that were taken to be canine in origin mixed with red- and white-coloured chemical products, as used to see fingerprints

Snip
There proceeded the search for possible blood traces in all of the apartment, using a variable- wave light source appropriate for the task.This search resulted in the detection of several spots having a red-brown tone that suggested blood, which were subjected to a "Kastle-Mayer" peroxidise test, the result obtained, in all cases, being negative.

There also proceeded the observation and search for blood traces inside the apartment using a chemical product to find latent blood traces. In the application of the referred product no results characteristic of the presence of blood traces were found
http://www.mccannpjfiles.co.uk/PJ/5A_FORENSIC_4_5_7.htm


We've all watched the video of a dog familiar with crime scenes reacting excitedly on the approach to apartment 5A .

Why would he do that unless, to paraphrase Martin Grime, he smelled a scent with which he was familiar?  Could that scent to which he was familiar have been the scent of a crime scene where he would be able to participate in what to him was the game of search? as per his training.

At a later stage swabs were indeed used for laboratory testing after the British dog inspection ~ 12 Processos Vol XII Page 3224 to 3225  http://www.mccannpjfiles.co.uk/PJ/PORTUGUESE-FORENSIC.htm ... but the first Portuguese investigation used chemicals prior to the British dog inspection. http://www.mccannpjfiles.co.uk/PJ/5A_FORENSIC_4_5_7.htm

Sorry, I didn't read far enough. I expect it was Luminol. I also expect he'd come across it before. It might indeed have told him he was approaching a crime scene, but would it have caused alerts?

I would say the apartment must have lit up the dogs senses given the numerous chemicals which the Portuguese CSI previously applied to floors, walls, windows, door and furnishings etc. Was Martin Grime ever asked about this?

I seem to remember from somewhere that Martin Grime asked of the Portuguese officers if such chemicals had been used I've no idea where I've got that impression from so haven't mentioned it prior to now as I have no cite for it.

It is from there that I began thinking about it ... I don't think he gave any reason for asking but just the fact he did ~ if my memory of it is correct ~ suggests there must have been one.

IMO the thread is irrelevant anyway.
Mr Grime's report and any forensic reports become evidence under Portuguese law.
Should the case come to court any such report is subject to scrutiny and evaluation by the court.
The Judge may choose if he so wishes appoint an expert in the field, from anywhere in the world, to explain the significance of the reports to the court.

Well we know the child disappeared without trace sometime between 17:30 and 22:00 on May 3rd 2007.
Beyond that is anyone's guess. The sad fact is a whole industry grew up on the back of it and we, like it or not, are part of the ensuing circus witnessed by our presence here. If we all found it as thoroughly distasteful as some suggest, this forum would not exist.

I thought that was a good point.  If we can see traces of Luminol we might think we are approaching a crime scene.  So they must have thoroughly cleaned the apartment after the PJ left.
No doubt the dog could sense luminol.  How that alters Eddie's response is unknown.

I don't think dragon's blood is anything extraordinary and I have no idea why it is called that as it is just another fingerprint powder ... they could have called it red.

Snip
Fingerprint powders are supplied in field kits in several colors, but black, gray, and dragon's blood are the most frequently used. The commercial powders have been developed over many years. They are dependable and of the proper composition. Choosing the powder that best contrasts with the background is a good rule of thumb to follow. Dragon's blood has the advantage of showing up on either a dark or light background. However, the choice of powder depends upon the objective of the investigator-whether the latent print is being developed for photographing or lifting. A test should be made of the area selected for the test print. First, it should be lightly brushed with powder to see if any unseen latent fingerprint is actually present. Then the surface can be wiped clean and the test print made and processed

I agree with G-Unit that the unnamed chemical used was probably Luminol.

We have only seen video of areas associated with McCann which makes it impossible to assess the dog's reaction on approach to other places ... but Martin Grime makes reference to the dog becoming excitable as he walked along the pathway to the door of 5A.
To the extent that he did not obey the 'sit' command prior to entry.  We saw it demonstrated in the garage sequence that he was trained to sit and then given the command to search.

We've seen the window which the dog had to pass covered in dragon's blood (fingerprint powder) precisely the area as noted by Martin Grime, where his intense interest began.
We have also seen his lengthy inspection of the apartment sniffing everywhere and anywhere before eventually barking.

Thank you for finding that information on Dragons blood Brietta. 

I can understand why the PJ didn't release videos of the dogs in the other apartments as they didn't alert to them so what would be the point from their point of view. However, from our point of view it probably would have been better to see the dogs behaviour and Martin Grime guiding them so that the questions some have asked, regarding his possible directing the dogs would be silenced or held up as correct. I believe that he was professional and did it correctly as he had been doing the job for years.

I also cannot see the use of chemicals affecting the dogs as they would have been used to searching crime scenes with forensic residue.  From what I have seen and read cadaver dogs with their incredible noses do not alert everywhere only in specific places which would indicate that the chemicals are irrelevant. 

All the above post is IMO.

5A was the first location searched in Portugal. Perhaps that contributed to Eddie's excitement as he began to do his job. We don't know which areas of the apartment were sprayed with chemicals, nor do we know if any of them have been studied for their effects on the work of these dogs. Therefore we're really unable to reach any meaningful conclusions in my opinion.

I can understand why the PJ didn't release videos of the dogs in the other apartments as they didn't alert to them so what would be the point from their point of view. However, from our point of view it probably would have been better to see the dogs behaviour and Martin Grime guiding them so that the questions some have asked, regarding his possible directing the dogs would be silenced or held up as correct. I believe that he was professional and did it correctly as he had been doing the job for years.

I also cannot see the use of chemicals affecting the dogs as they would have been used to searching crime scenes with forensic residue.  From what I have seen and read cadaver dogs with their incredible noses do not alert everywhere only in specific places which would indicate that the chemicals are irrelevant. 

All the above post is IMO.

That is precisely my point. That the dog was "used to searching crime scenes with forensic residue."

Eddie did not alert immediately but he did become exited by 'a scent he recognised' as he approached along the enclosed passageway outside the bedroom window ... we have watched the video and we have witnessed that.

The dog had primed itself for action in that passageway ... we have witnessed him straining at the lead in the video.

The use of chemicals might not affect the alerts but might explain eddies alleged initial excitement when entering 5a


well you don't know do you so it is all just guess work.

It could go both ways [evidence could be missed] if that's the case imo

5A was the first location searched in Portugal. Perhaps that contributed to Eddie's excitement as he began to do his job. We don't know which areas of the apartment were sprayed with chemicals, nor do we know if any of them have been studied for their effects on the work of these dogs. Therefore we're really unable to reach any meaningful conclusions in my opinion.

I have found a paper detailing scientific research regarding VRDs and such chemicals.  At he moment I can't make head nor tail of the information which is detailed and quite extensive ... when or if I do I will bring it to the forum.
Googling turns up a few references worth having  look at.

I agree.
Evidence of an abductor may have been missed.

No evidence is no evidence. Isn't that the argument used against the dog alerts?

NB the dog alerts at the hire car proved valid ... and did not substantiate police suspicions ... in fact, proper procedure in evidence gathering and subsequent forensic confirmation exonerated the McCanns.

No evidence is no evidence irrespective of what is being argued.  Enough deflection now ... back on topic please.

You can see Eddie in action in the other Tapas 9 apartments on this video. Note that Grime is walking down the same pathway for a second time & imo there was no "straining at the leash" visible then.

Well an educated guess  lol ...they checked for that before the dogs came.

Not only no straining at the leash ... he remained sitting for a considerable period while waiting to be told to start work.

An entirely different approach to that also recorded on video when he burst over the threshold of apartment 5A.

So was there a point you are making?

There were no CSI chemicals in 5B, 5D or 5H which may have primed the dog to alert.....

So are we sure the other apartments occupied by the Tapas 9 were not checked for traces of blood with luminol?

Were they just given a general search and a sniff over by a sniffer dog in the early stages?

The other apartments were not treated as a crime scene & there were no forensics harvested from them based on the evidence in the files.
