Amaral and the dogs

[Jean-Pierre]

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) ?

Why is that relevant?  Eddie was trained to alert to dried blood.

"'The dog EVRD also alerts to blood from a live human being or only from a cadaver'
 The dog EVRD is trained using whole and disintegrated material, blood, bone tissue, teeth, etc. and decomposed cross-contaminants. The dog will recognize all or parts of a human cadaver. He is not trained for 'live' human odours; no trained dog will recognize the smell of 'fresh blood'. They find, however, and give the alert for dried blood from a live human being."

Precisely.

Eddie allegedly alerted to the cellular material on the Renault key fob ... Keela's alert to the same item would appear to identify it as blood.
The lab identified the source of the substance to be Dr Gerry McCann ... therefore Eddie alerted to blood from a living person.

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.

Forensic scientists don't know what these dogs are alerting to because they haven't been able to separate the components of 'cadaver scent'. That's why they can't reproduce it in the laboratory. Eddie was trained on decomposing piglets because the scent is very close to that of decomposing humans. As the dogs become experienced they can identify the scent of a decomposing human being and that is what they alert to.

They also alert to dried blood from living humans and (Eddie) coconuts ....

I'm aware of that. And also that there are numerous compounds that vary in presence or strength according to the type of substance decomposing and the PMI.

Is Grime a forensic scientist ?

Xcuse me.  Blood only comes from live humans.  Dead humans don't bleed.  Hope this helps.

Incorrect.

Blood can seep from a dead body from a wound.

Hope that helps.

Seep?  Does it stop clotting then?  I don't think bodies seep  blood if they are killed and then moved.

[pegasus]

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

Several times, but spot the difference.

Agree. For a limited time. 

Question for you - is there a detectable difference between blood that has come from a recently deceased person and blood that has come from a living person who has bled?

Why do they fail to alert on one occasion then alert some minutes later

Blood pressure in anyone dead is zero, therefore blood-loss (from anyone dead is much less likely.

Still, it can happen, and where it does, it congeals in a form very different from blood lost by a living person.

Thank you Ferryman.  Would this difference be detectable by a dog?

Yes........and...............no.
