Have the dog alerts any significance?

[Eleanor]

Yet another layman's view.

So is it okay for a working Cadaver Dog to pick up items of interest and then to throw them around?

[jassi]

We are all laymen on here.

[Mr Gray]

We are all laymen on here.

Of course we are
Therefore there should be no discrimination re who can be criticised

Who knows, probably the expert does.

[Mr Gray]

Who knows, probably the expert does.

the expert did not give a very good answer when questioned by the pj about the incident

The expert gave the answer you would expect.

[Mr Gray]

not the answer i would expect and certainly didnt sound like an expert

So the dogs are reliable, and as the dogs alerted in Apartment 5a there must have been a corpse in there and it was most probably Madeleine's despite the lack of any corroborating evidence, is that the correct conclusion to be drawn then?

You really haven't a clue what an alert means.

[Mr Gray]

You really haven't a clue what an alert means.

even grime is not sure what the alert means

[Angelo222]

Here is an example of why the dogs alerts should not be taken as 100% reliable.

The dog & handler team in question (Tracy Sargent, impressive CV) is reportedly one of the best in the USA. The search was undertaken 11 months after young Deorr had disappeared and after the terrain had been covered by deep snow for 7 months. 5 alerts, only one corroborated by a buried bloodied towel.

*snipped*
Investigator Sargent reports the “Chance” whom is a trained cadaver dog hit five different unknown targets. Chance is trained on human decomposition and human blood pathogen decomposition.

The following are the hits (limited) :

1. “Diaper Tree Area” – This is the area to which it was testified that “a diaper” was hung in the tree in the campground.
2. 139 Feet East of the Cattle Guard in the camp ground – in a loose ground area.
3. 10 Feet Due East of camp site.
4. 2.24 miles due Northeast of the 15 mp stake, in the ravine near 221 southeast fence.
5. Camp site ground .75 miles due East of the camp ground.

Area 1 : There was no evidence obtained.
Area 2 : Excavation was undertaken by LE and KIC – this area needs to be further exhumed and was turned over to Law Enforcement for further investigation by their team.
Area 3 : This area was excavated by hand – and found that a previous animal had been buried at this location. During the burial the subject who did the burial cut his hand and bled into a towel wrapped around the animal.
Area 4 : Investigators have turned this area over to law enforcement.
Area 5 : Investigators believe this site may have been a “holding site” for some type of human body.

There was no other evidence found.

A dog will find the scent of whatever it is trained to find.  They are 100% reliable.

even grime is not sure what the alert means

Of course he does. To suggest otherwise borders on libel.

[Angelo222]

This was the conclusion I came to as well, but since the sighting by Gerry at 9:05 of Madeleine would preclude the cadaver odour coming from her.

Think secondary transfer Rob.

[Mr Gray]

Of course he does. To suggest otherwise borders on libel.

no libel
im going by his statement
he says its possible its cadaver and its suggestive....he cant say for sure

[Angelo222]

Your knowledge and understanding of the dogs is flawed
and your argument is muddled

The dogs are reliable at finding evidence
That is what makes them valuable

The alerts themselves where no evidence is found are unreliable
Grime tells us they are unreliable as evidence

Harrison confirms this and tells us no inferences can be drawn from the alerts

The dogs are used worldwide to find evidence
That is their value

The argument can be settled very simply by answering this question

What do the alerts in PDL tell us
They tell us nothing....fact

They tell us precisely this.  That Eddie found a scent consistent with his target scent.

[Mr Gray]

They tell us precisely this.  That Eddie found a scent consistent with his target scent.

no they dont...you really do not understand

harrison and grime agree........no confirmation of what the alert was to
