I already commented on that. perhaps you missed it. I dont think a) he was talking about blood and b) does not suggest the scent travels throughout several rooms of a house, it is clear to me the scent originated in that room and not the bathroom.
And I find your theory quite implausible at best, but you are free to have your opinions.
Ok what was done was we deployed the victim recovery dog into the apartment and by experience and the training of the dog what I first noticed is that as soon as I came in that the dog was very excited and as a handler I can pick up his body language etc and it would appear to me that as soon as he has come into the house he's picked up a scent that he recognises and he has then gone through the apartment trying to source where that scent source has come from and as he has worked through the house the only two places where he picks up enough scent to give me the bark alert are in this bedroom, in this corner where he was barking.
What we have to be able to understand in a situation such as this is in a hot climate with the apartment being closed down, the scent will build up in a particular area. If there isn't a scent source in here, i.e. a physical article where the scent is emitting from, any scent residue will collect in a particular place due to the air movement of the flat, the apartment and what I would say in this case is that there is enough scent in that area there for him to give me a bark indication but the source may not be in that cupboard, the source may well be in this room somewhere else but the air is actually pushing into that corner. But strong indication and I would say its positive for things that he is trained to find, which will be part of a separate debrief.
