Note Grime said cadaver scent contaminant...not a cadaver. sceptics almost all read this as cadaver...they are wrong
We all know that a cadaver wasn't in Apartment 5A at the time the dogs were used. The issue is where did the cadaverine originate. The Police use a second dog (when there is no body) in an attempt to pinpoint areas where it may be possible to find human blood. Keela if you read the report was incredibly accurate in relation to finding the exact spot where swab 3A yielded human cellular material. To the point where they removed an extra tile to find tiny traces of human cellular material in the area where the dog alerted.
To quote Martin Grime "The second dog that we've seen work today is the crime scene dog Keela. She will only indicate to me when she has found human blood, only human blood and it is only blood and there must be something there physically for her to be able to alert to me that's she has actually found something. At this point over here where the victim recovery dog has indicated, as you saw on the video, the crime scene dog had actually given me what we call a passive indication where she freezes in this spot here which would indicate to me that there is some human blood there. She will find blood that's historically very old and she will find anybody's blood, any human blood, which is important to make sure that everybody knows. The fact that there is other scientific methods being used may stop you recovering any DNA but if you try we'll see what happens. But she is very, very good and when she indicates there is always blood there"

"Subsequently it was asked of the undersigned that they watched the films of the searches performed by the dog specialised in detection of human blood so that they obtained an understanding of the area from where the tiles should be collected and how many tiles they should collect.
After seeing the images and in agreement with the officers of DIC of Portimao it was defined that the undersigned should proceed with the recovery of four tiles. It was also defined that this operation of recovery of the tiles would also be filmed.
When looking at the images referred to above it was observed that the floor tiles to be recovered were situated in an area of the living room next to a window where there was a sofa and that the tiles referred to were underneath that sofa.
Detailed shots of the living room area and floor area from which the tiles should be collected.
As requested by investigating officers of the DIC of Portimao it was performed the lifting and respective recovery of the four tiles and of the skirting board next to them (they being identified with numbers 1 to 4) using a tile trimmer, a flat chisel and a hammer.
After the recovery of the four tiles and the skirting board the dog specialised in the detection of traces of human blood was put into the area from where the tiles had been recovered, the English police officer who coordinated the movement of the dog, Martin Grime, having informed the undersigned that they should proceed with the recovery of another piece of tile that was close to the area from where the tile identified as number 1 had been lifted, that terminating the recovery of the tiles signalled by the dog. As requested the undersigned performed the lifting of and the recovery of the piece of tile indicated."
Both dogs did the job they were trained to do. There is nothing they added to the investigation to prove a corpse had been in the apartment but the cadaverine contaminant has come from somewhere and something only the McCann's had contact with. It wasn't from nappies or rotting meat - could it have been the post mortem's Kate reportedly attended? I work in a hospital and have never been aware of a GP or anaesthetist having direct contact with a corpse during a PM - but it's worthy of further investigation. Particularly given there is a missing person whose chances of now being alive are statistically very unlikely in my opinion.
Also given the dogs 90% - 95% accuracy the chances of both of them mistakenly alerting to items belonging to only one family are miniscule. Far from being "irrelevant" it throws up incredibly serious scientific questions.
