I believe Eddie alerted to blood, which had been there and taken away. Eddie wouldn't have bothered with the McCann's bedroom if Grime hadn't kept calling him back, they he barked probably because there was a faint scent coming from the wardrobe where dirty washing had been stored. The clothes, I wouldn't call that an alert, Eddie sniffed them passed by them then suddenly barked picking them up in his mouth as if playing with them. Cuddle cat, well Eddie would have had plenty of time to alert to CC he picked it up and tossed it away. The car? come on do you honestly think the McCann's stored Madeline's body in a fridge? and then put her in the car to transport her somewhere with all the journalists following them? IMO
Firstly no I don’t think the parents moved the body after May 3rd.
Secondly don’t you think that all the other apartments at some point had items with blood on them that had been taken away or dirty washing stored in their cupboards? When Eddie barks that is an alert, that he picked the items up is irrelevant.
As to the bedroom are you accusing Grime of consciously cuing the dog ?
