Amaral and the dogs

The dogs are trained to find evidence

The dogs are trained to respond to a group of compounds which form as a result of decomposition.

Now again.

Where does it say, the dogs could not have alerted to a body ?

Grime and Harrison have both said the alerts have no evidential or intelligence reliability...we can only look at what the experts have said ...not what they have not said. We are all aware that there may have been a body in 5a.....and the dogs may have alerted to it...or they may not have...not much use...

I'm withdrawing my check calculations for now - because of the complication of the watermark.
However IMO it is likely that all 3 listed clothing items were in that pile for the entire meal.
Any assumption that they were being worn during that relevant time would be illogical IMO.

Live people bleed, especially in a Disaster situation.  They could well live for sometime after, possibly soaked in dried blood.

including dried blood.  Which can, as Eleanor says, be from people who are definitely  still alive.

So, with this information, how does a dog alert definitely mean that there was a dead human there at some time?

When the cadaver dog is teamed up with a second dog trained, only, to react to blood and (itself!) desensitised to blood.

That is why, in the Bianca Jones case, the (uncorroborated) cadaver dog alert of Morse was accepted as stand-alone evidence of death.

The weak link in the Eddie-and-Keela combination was always that both dogs react(ed!) to blood.

If you were not worried by the dogs, you would not continue to post on the topic.

Likewise, you will not convince me that the dogs alerts were false.

At the wardrobe, Eddie alerted, Keela did not, what does this mean?

Seeing as Eddie alerted (second time of asking, but not first!) to cuddle cat, and Keela didn't, who knows?

Can you cite evidence that dried blood from a living person will produce compounds after decarboxylation such as Cadaverine and Putrescine (from Lysine and Arginine respectively) ?

from what we have learnt...nothing ....how many times did eddie walk past the wardrobe without alerting

Why is that relevant? Grime has stated that Eddie would react to dried blood from a living human being. He's less clear about which other decomposing "body fluids" he'd also have reacted to.

dried blood does not produce cadaver scent

Precisely.

Is Grime a forensic scientist ?
