There has been much said about the Cadaver dog used in the McCann case. One set of people saying that the scent given must be that of Madeleine McCann. Whilst the other side is vehemently denying it was Madeleine and it could have been a number of things.
Even the dog handler said in his report the following:
The tasking for this operation was as per my normal Standard Operating Procedures. The dogs are deployed as search assets to secure evidence and locate human remains or Human blood.
The dogs only alerted to property associated with the McCann family. The dog alert indications MUST be corroborated if to establish their findings as evidence.
Therefore in this particular case, as no human remains were located, the only alert indications that may become corroborated are those that the CSI dog indicated by forensic laboratory analysis.
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.
Well even to me as a simpleton who’s not trained in dog handling, I can fully understand what Martin Grime is saying, the alerts given by Eddie are only suggestive and Martin Grime states categorically that no evidential or intelligence reliability can be made from these alerts unless corroborated by hard evidence, ie human remains.
Martin Grime also tells us in his personal profile the following
The dog has also been trained to identify ‘dead body’ scent contamination where there is no physically retrievable evidence, due to scent adhering to pervious material such as carpet or the upholstery in motor vehicles. Whereas there may be no retrievable evidence for court purposes this may well assist intelligence gathering in Major Crime investigations.
The result from scientific experiment and research to date would tend to support the theory that the scent of human and pig decomposing material is so similar that we are unable to ‘train’ the dog to distinguish between the two. That is not to say that this may not be possible in the future.
Even if samples collected proved beyond shadow of doubt they came from a decomposed body, unless that body is found, those samples could have come from decomposing bodily fluids from a live person.
If human remains are found where Eddie alerts to then and only then can Eddie’s markings be 100% reliable, up until that time they are only suggestive, a may be, a could be and they are nothing more than that.
We know this is true because it has been given under oath in the Anthony case that gripped the American nation.
In an article written about the testimony of the Dog Handlers in a blog post made by Nancy Grace it states this:
On cross examination, Brewer stated that dogs can alert on bodily fluids from a living person that are now decomposing. Defense attorney Jose Baez gave the example of blood or a fingernail from a live person, and Brewer agreed that it is possible a dog would pick up on that.
Here is the video of that testimony.
All dogs that are trained are a valued asset to any Police investigation and no I wouldn’t get on a plane if a dog was barking until it was checked out, but neither would I assume automatically that the plane was definitely going to explode in mid-air due to a bomb.
Just like when the dog at the airport barks at a potential drug carrying passenger, neither will I say they are guilty until the drugs are found on them to prove the dogs alerts.
The dogs in any situation are only indicators they are not evidence, what is found forensically or on the person is the evidence. As Eddie did not find human remains that belonged to Madeleine McCann, I will along with many others still consider Madeleine to be a findable living child. And neither will I believe that just because he could have alerted to a cadaver scent, that it is Madeleine’s. There are, as Grime states, several scenarios where those alerts given by the dog, could be a result of possible cross contamination.
Those are the facts, it is in the files, it is on the video, now those in doubt can either believe the facts or continue on this path of unsubstantiated reasoning that the dogs alerted to a dead Madeleine and basically make a tit of themselves in the process.
Just one more thing, care to tell Sgt. Kristen Brewer that her dog was not up to standard Jilly.
Of course Jilly won’t because in the UK our cadaver dogs are NOT trained on human cadaver sources, whereas the dogs used in the United States are trained using human cadaver sources. And this comes from the same report written by Martin Grime.
Operational finds backed by forensic corroboration have shown that the system adopted by me in the training of the dogs is both effective and efficient. Acting in my role of advisor to the U.S. Justice Department I have facilitated assessment of numerous cadaver search dog teams in the United States.These dogs are exclusively trained using human cadaver sources. When I introduced pig based products into training assessments 100%! of the animals alerted to the medium.
