Dog alerts indicating Cadaver Odor

[Gildas]

Peer reviewed research into scent dog accuracy for false positive and false negative alerts in real life operation. Most suggest a maximum of 90% accuracy but some are as low as 30%.

I am happy with any researched figure less than 100%- nothing, especially dog and handler reactions is 100% accurate. All measurements have error rates.

Thank you for your reply, Debunker.

It is logically correct. Do a thought experiment- an amputated piece of a body will decompose in similar ways whether the person is alive or dead.

Menstrual flow includes blood.

Seminal fluid is created from blood.

Suppurating wounds create cadaverine and putrescine.

And so on. All in the literature.

and all left lying on the floor three months later in just flat 5a where a missing child went missing from, ok

Since we only have Mr Grime's cv and reports to go on in this case and concerning this dog, where in any of that does he say that Eddie alerts to decomposing substances from people who are alive, apart from blood?

Well, I suppose the sex clean-up tissues he alerted to in Jersey could be a case of necrophilia...

What a horrible post, and semen chemicals dont linger in the air three months later, the mass of bodily decomposition compounds do though, they are about 400 as opposed to two or three off semen

Cite for that claim please.

google does the trick dci mosg times, give it a go

I don't need to. It was you doing the accusing, it up to you to provide the proof.

More than 400 ! It is much more subtle than cadaverine and putrescine synthetic compounds.

[AnneGuedes]

btw cadaverine couldn't fool Eddie.

[debunker]

Cadaverine and Putrescene are organic compounds produced by decaying human bodies. Eddie reacts to both and also to dried blood from a still living person. He does not need to smell all resultant compounds to alert. Blood itself gives off only a few of the many chemicals associated with human decay.

I was just pointing out that such things were within Eddie's training parameters as substances from a living person.


That apartment had been rented out 4 times after Madeleine disappeared.

The leaving date of the last (known) occupants was 26 July - one week before the inspection.

He may even have reacted to the lingering scent of a bandaid that fell off a recent occupant's foot - who knows?

If it was at all likely that Eddie was as indiscriminate in his alerts as you suggest,  it's begs the question  ...  why wasn't   he  alerting all over PDL ?   ... rather than only in the apartment where a missing child was last seen ?

Mods, I'm uncomfortably aware that discussion about Lee Rainbow has (again) taken this thread off-topic.

Would it be possible to hive off those posts about Lee Rainbow into a separate thread?

And again apologies.  I don't think I began the discussion but I was principally responsible for nurturing it.

Should have begun a new thread to continue an (interesting) meta-debate.

I will be more disciplined in future ...

Certainly dogs take cues from their handler that they are "working".
