Was Eddie The perfect Dog for the role ?

[Icanhandlethetruth]

This came to me this morning. Bear with me it may take some time.

If we can confirm that UK dogs trained on piglets will alert to human remains and pigs. So likewise in the US, when dogs trained on human remains were introduced by Mr Grime to pig based material 100% of the dogs alerted we can deduce that the scents are indistinguishable to trained dogs. So before Eddie trained on humans he would alert to humans and pigs and after he was exposed to human remains in a training situation he also would alert to humans and pigs. So its not much of an enhancement. So I re read Mr Grimes personal profile statement and its actually quite clear what the enhancement is. See the cut and paste from his statement below


“and has trained exclusively using human remains in the U.S.A. in association with the F.B.I. The enhanced training of the dog involves the use of collection of 'Dead body scent' odour from corpses using remote technical equipment which does not contact.


He mentions the training in the USA using human remains and ends the sentence, He starts a new sentence concerning the enhanced training and it references the method of collection by means of no contact with the corpse. This is the enhancement. This is the E in EVRD.

Now If I can elaborate what role this may have played in the decision to utilise Eddie’s skills.
 
Give me a few minutes before you pile in and rip into this. I'll have a quick cup of tea before I post Part 2

The primary use of the STU-100 was to collect the scent from human remains for potential evidential use. It was estimated that sterile gauze pads could hold the evidence for 11 years.
The sample was taken from the air around the human remains and the sterile gauze pad that captured the scent was then taken to be stored in glass jars as evidence.

I believe Mr Grime may have witnessed this process and realised it may be a way to enhance Eddies abilities to recognise the scent that may be in the environment around where a dead body has been rather than a dead body itself.

Thus Eddies was trained using these gauze pads away from any actual human remains and Mr Grime obviously had the opinion that it enhanced Eddies abilities as he unilaterally added the famous E to VRD.

Mark Harrison could have known Mr Grime was working on an enhancement that wasn’t focused on the location of a body but the location of scent only and so called Mr Grime, Eddie and Keela over to Portugal. This would address some of the anomalies that exist with the use of the dogs.

1. Why use a VRD at all. Everyone knew there was no possibility of a cadaver still being in situ at the apartment.
2.Why fly Eddie over from the USA at all, why not use one of the many other UK that were trained to locate human remains.( Can someone verify this is true and not the he flew from the UK)
3. I always wondered why Mr Grime went on for so long in his statement about the STU-100 as it was never used in Portugal and seemed to have no relevance.

Very salient point lost on some imo.

Yup, you've lost me.  What's a STU-100 when it's at home?

Its in Mr Grimes statement although he omits the U and calls it a ST100 Scent Transference Unit.

Tell us more about this thing and why it makes Eddie so special.

Is this a device that he designed and made, and is it in widespread use now?

Abstract
The Scent Transfer Unit (STU-100) is a portable vacuum that uses airflow through a sterile gauze pad to capture a volatiles profile over evidentiary items for subsequent canine presentation to assist law enforcement personnel. This device was evaluated to determine its ability to trap and release organic compounds at ambient temperature under controlled laboratory conditions. Gas chromatography-mass spectrometry (GC-MS) analyses using a five-component volatiles mixture in methanol injected directly into a capture pad indicated that compound release could be detected initially and 3 days after the time of collection. Additionally, 15 compounds of a 39-component toxic organic gaseous mixture (10-1000 parts per billion by volume [p.p.b.(v)]) were trapped, released, and detected in the headspace of a volatiles capture pad after being exposed to this mixture using the STU-100 with analysis via GC-MS. Component release efficiencies at ambient temperature varied with the analyte; however, typical values of c. 10% were obtained. Desorption at elevated temperatures of reported human odor/scent chemicals and colognes trapped by the STU-100 pads was measured and indicated that the STU-100 has a significant trapping efficiency at ambient temperature. Multivariate statistical analysis of subsequent mass spectral patterns was also performed.

Again I have no idea.

Answer - no ( I didn't know the answer to the question when I asked it).

STU-100
( Scent Transfer Unit )

What is the STU-100 ? The Scent Transfer Unit (STU-100) was specifically designed for Forensic Specialists, Investigators, Evidence Response Teams, Identification Departments and Scent Dog Handlers. The Scent Transfer Unit allows law enforcement to collect evidence from any item without destroying fingerprints on the item, collect trace evidence at a crime scene without contamination, collect scent evidence from hard to access places not accessible to a search dog and gives law enforcement a scent pad to store in scent banks for future use on repeat offenders.

The STU-100 was designed and built to assist law enforcement with the collection of scent and trace evidence. It provides a method of preserving evidence for extended periods of time because scent is evidence. The STU-100 requires common sense, good judgement, a sound working knowledge of scent and what it takes to protect it from contamination. Properly handled and operated, the STU-100 can produce unbelievable results.

History of the STU100
Very first Scent Transfer Unit --- The Scent machine"The Scent Machine" In the late 80'S I tried using a vacuum process to collect the scent into a sterile gauze pad that I could move around and better yet, I could collect the scent and keep it for long periods of time. A number of 110 models were tested. I called them "Scent Transfer Machines" however as with most first inventions they were big, heavy, cumbersome and while they did the job well they were difficult to handle.

In those tests the gauze pads had direct contact with the cadaver, rather than the remote collection of scent contained in the air around the cadaver. UK law does not permit the use of the former for training cadaver dogs in UK.

3. I always wondered why Mr Grime went on for so long in his statement about the STU-100 as it was never used in Portugal and seemed to have no relevance.

IMO it appears Grime emphasised the use of STU-100 as evidence that Eddie was trained to alert to remnant human cadaver scent when no body was in situ. Other UK cadaver dogs, which could only be trained on decomposing pig remains, had not received this enhancement during their training ergo, on paper, Eddie had superior capabilities to standard UK dogs.
Mark Harrison did recommend in his report that both the area around the OC creche should be examined by Eddie & Keela and a team of VRD's should be deployed on the land to the east of Luz. Neither of those deployments took place, for reasons unknown.

With regards to residual scent from human cadavers & the difficulties involved in getting a jury to accept alerts without bodies as an accepted science, the Casey Anthony trial is an excellent example of just how much more research is still required. There is a good white paper here https://scholar.smu.edu/cgi/viewcontent.cgi?article=1042&context=scitech    which is lengthy but well worth a read.
There are also links to further research papers here regarding remote collection of scents.
