The key fob (to which Eddie alerted) was taken out of the car, placed inside a sandbox and buried for Eddie to alert to a second time.
Eddie did so.
The key fob was sent to the FSS and found to contain Gerry's DNA.
(Surprise, surprise, Gerry drove the car).
So there you have it. If Eddie alerted to a scent from
the inside of the car then the seal must have been damaged
Anyway, Gerrys blood was on the key, so *IF* Eddie was alerting to that then it was blood = Gerrys.
With Keela having alerted in the boot, all she was saying was blood. Eddie also alerts to blood, so *if* they BOTH alerted it does NOT mean cadavar.
In other words, *If* the door seal was damaged and scent escaped it does NOT mean Cadavar ... it just means BLOOD.
TBH, I did not like the way that Eddies nose seemed to be going ... not around the very edge of the seal, but an inch or so from the seal. I hope that I am remembering this correctly. mercury please correct me if I am wrong *&*%£
There are many causes for blood, from cuts and scrazes, to mozzy bites, to menstration, etc
