Are Victim Detection and Forensic Evidence Search Dogs reliable?

[mercury]

don't forget the rotting vegetation and fertilizer you have on your shoes!

And sweat...cadaver dogs alert to BO..obviously everyone used deodorant religiously except Anyone around a missing child

There's an inverse relationship between the use of emoticons and intelligence

Poor dave, very poor.

I'll remind you of that next time you use them.

Or 'who let those incredibly unreliable dogs out'.

I'm sure those words could be overlaid onto the song.

Oh ah, oh ah.....

Don't you know?

yes, various things, not all of them yer actual dead body.

I thnk if a cadaver dog alerts in a case of a missing person who has never been seen since, in the last place she was seen and no where else, in a search. 7 residences, (where no one has gone missing) and various outside areas, chances are hgher that the dog alerted to cadaver scent rather than someone's saliva or residual plaster (or mushrooms) don't you think? or are the chances equal.

You have just drawn conclusions to fit your bias

Same comment.
Now demonstrate how I have done that.

Well, let's say Shannon Matthews had been locked up in a dungeon and was still there to this day, undiscovered but being kept alive by her captor, you would presumably be insisting she was dead, right?  Similarly, you'd be convinced that Thomas Quick actually murdered all those people in Sweden on the basis of Zampo's alerts in the woods to this day, if it hadn't been revealed that he made a false confession to the murders, wouldn't you?

You should attempt to at least stop putting words into others mouths as I was not insisting on anything was I? I asked you a question about probabilities surrounding the known facts and what various posters here keep saying are possibilities.

What it boils down to. is this: no one knows precisely what caused. the dog alerts and there could be a number of different explanations for them, including the one time presence of a cadaver.  Working out the probability that it was Madeleine's corpse they were alerting to is up to someone far more brilliant than me (over to Alice, perhaps?)

[Lace]

Were any of those found in the samples collected and analysed ?

A simple yes or no will suffice.

Did they take samples from the tiles in the bedroom?

Now can you answer the question,  was it definitely cadaver scent Stephen?

Apparently the dogs alert to a) cadaver b) blood. Take your pick.

Can you say it wasn't ?

Or do you prefer pigs, compost, fertilizer............. ?

[Lace]

Ah blood G-Unit the blood that could be human or pig blood,   fertiliser maybe?

You may laugh about it,  but a child was deemed dead because of the dogs findings.

[Lace]

It wasn't,  there good enough for you?    Madeleine did not lie in that apartment dead for 2 and a half to three hours then  hidden somewhere so spectacular that no one could find her,  then weeks later taken again in a car for disposal.

Was it DEFINATELY cadaver scent Stephen?

Unfortunately, in such a situation the trier of fact may easily be misled as to both the accuracy and precision of the dog's actions: Accuracy in the sense that the dog (depending upon its level of training) may be reacting to something other than residual scent from decomposed human tissue; precision in that the dog may be reacting correctly to the scent of decomposed human tissue, but imprecise in the sense that the dog is not differentiating between whose decomposed human tissue is giving the scent. Further, there may be legitimate reasons for the scent being there: someone may have been injured and left bloody clothing there, someone may have left a used sanitary napkin, etc. Our research demonstrates that residual scent from decomposed human tissue persists in a closed building for many months at levels sufficient to cause a trained dog to alert.
