That because both dogs react to the same place must mean the alert was to blood, it's possible and probable if you like, (stretching it because why use Keela at all if Eddie alerts to blood in an area which would only require use of luminol to confirm) but not certain...the reason I added that a strong DNA match was required as corroboration, was not because it would prove just the presence of blood but that a victims DNA was found, which is the nearest corroboration you can have for the cadaver dog alerts to cadaver scent, iyswim....
your two premises are correct IE Eddie alerts to blood, keela alerts to blood, but your conclusion is not,because Eddie also alerts to dead body scent which is different, if it was not different there would be no need in the first place to make a differentiation between the two and use two types of dogs..anyway bored with labouring points....you have your beliefs,(right or wrong) I have my understandings(right or wrong) bit pointless to keep argueing the toss forever more...life's too short lol
No.
In fairness, you've set your position very clearly and I (now) understand what you are getting at. In the Attracta Harron case, Eddie alerted to the car of the man eventually convicted of her murder and human traces were found (blood, I think) which matched the DNA profile of the victim, and that was instrumental in the subsequent conviction of her murderer.
So yes, in the
abstract, it is possible that Keela and Eddie could alert in the same spot, and evidence could be uncovered with cracks a crime.
You make a good point well.
In the specific, however, (as I'm sure you realise) finding traces of Madeleine's blood in the apartment would be no big deal. And, of course, both dogs indicating in the same place would indicate blood rather than cadaver odour.
In fairness, Amaral understood that, and said so in his book.
