Cadaver Dog Alert Convictions without a body

Would she have been dead long enough to have given off cadaver scent?

Cadaverine develops quickly after death.

One of the questions surrounding human cadaver dogs is how soon after death they can recognise a corpse, and how long a "fresh" corpse must remain in one place for a dog to detect that it has been there. In a study published last year, the forensic pathologist Lars Oesterhelweg, then at the University of Bern in Switzerland, and colleagues tested the ability of three Hamburg State Police cadaver dogs to pick out – of a line-up of six new carpet squares – the one that had been exposed for no more than 10 minutes to a recently deceased person.

Several squares had been placed beneath a clothed corpse within three hours of death, when some organs and many cells of the human body are still functioning. Over the next month, the dogs did hundreds of trials in which they signalled the contaminated square with 98 per cent accuracy, falling to 94 per cent when the square had been in contact with the corpse for only two minutes. The research concluded that cadaver dogs were an "outstanding tool" for crime-scene investigation.

Thanks Pat, However it was November in Gloucestershire and outdoors that she died. However even if he didn't go indoors then, he would have had to go home eventually, but probably had a shower in the bootroom, before going into the lounge....We don't really know, such details.

He was alone on that farm. Eddie alerted to cadaver. That's his job.

You still don't understand what dogs alert to and why do you?  The corpse in the trial above had been dead for three hours.  Are you suggesting Prout spent three hours with his wife's corpse before sitting on the sofa and having a glass of whiskey?

[pathfinder73]

Prout's clothes were contaminated from handling a dead body. Eddie knows that scent.

The process in which the human body decomposes starts just minutes after death. When the heart stops beating, we experience algor mortis, or the “death chill,” when the temperature of the body falls about 1.5 degrees Fahrenheit an hour until it reaches room temperature. Almost immediately, the blood becomes more acidic as carbon dioxide builds up. This causes cells to split open, emptying enzymes into the tissues, which start to digest themselves from within.

In the early stages after death, cellular metabolism slows as the internal systems begin to break down. Lack of oxygen in the tissues triggers an explosive growth of bacteria, which feed on the body’s proteins, carbohydrates and fats, producing gases that cause the body to smell and to swell. In 1885, the German physician Ludwig Brieger identified two nitrogenous compounds – putrescine and cadaverine – as the chemical basis of the smell of putrefaction; there are, in fact, a host of volatile compounds involved, including substances related to butyric acid.

lol, the dogs again......

I live not far from the Prouts. The dog alerted but they couldnt find the body. That is why he ended up in prison because they knew he had killed her. He had hidden her in a pipe and buried her, he had the means to do this.

They knew she was dead and she had lain behind the settee.

Why cant believe just accept these dogs are highly trained. Once again they can scent death, but they cant tell you who died.

God its like Groundhog day.

It is like groundhog day...why can't people accept that the dog's don't prove Maddie died in the apartment...why don't they understand what Grime said...why don't they understand that it is a fact that Maddie may still be alive

We do accept your propaganda mission to attempt to discredit any information that is remotely incriminating to the McCanns.

We also understand that the dog was trained to alert to dead bodies. The dog alerted and the fact that no physical evidence was found does not negate the alert. No one was known to gave died in the apartment and only one person known to gave gone missing.

The dog is trained to alert to cadaverine...so what do the alerts prove...simple question but one you will avoid

From that standpoint she maybe in the lawless village 10 miles from PDL, according to the wisdom of Edgar.

So dave, let's have your insight as to where Madeleine is, playing happy families.

So you nor slarti can answer a simple question re the dogs....

It is a simple question and one which the supporters have tried to obliterate for years. The dog alerted to cadaverine, the blood dog didn't alert, that implies a body or contamination. For some reason it was decided to go with "no evidential reliability" rather than identify any contamination.

Think about it.  If Prout was himself contaminated with death odour (which I accept he was) then he would have transferred that odour to many places around his bungalow.  So why did the dog ONLY alert to a spot between the sofa and the patio doors?

so you say the alert implies cadaverine..that is NOT what Grime says....

Grime says that the dog MAY have alerted to cadaverine...so the alert actually proves nothing
