But the alerts we do have could gives us a clue where to look for this "real evidence".
No they dont Rob
Because both keela and Eddie had to be shown the same suspected places
... and for the alerts to mean anything (then only possibly, subject to forensic analysis) it was imperative that Keela DID NOT alert where Eddie did.
Only then it might have been cadavar odour, because Eddie was reacting to cadervesce and Keela NEVER reacted to same.
If both dogs reacted then it was dessicated blood from a living person.
Eddies great flaw was that he had previously been trained as a blood dog, then later as a Cadavar dog ... so he reacted to both. Keelas input was necessary so that they could tell if Eddies reaction was to blood from a living person or to Cadavar odour.
Once a dog (Eddie) had been trained to react to something, he could never be re-trained
.... so Eddie would always react to
both cadavar odour and to the dessicated blood from a living person.
The clever bit was using Keela to rule out that it was dried living blood that he was reacting to, meaning that when she didn't react, the likelyhood was that it was cadavar odour that Eddie had reacted to. Subject to Forensic analysis.
Rob,
The main experts on this forum re the alerts seem to be Ferryman, Davel and Carana, altho several others are very knowledgeable too. Hope this helps.
