prima, you watched the video .... did you notice the victim was not placed directly on top of those pink sheets, there was some kind of blanket/bedspread underneath the body....I am sure LE took as evidence everything they 'know' is needed. JMHO
In one video they said the other hand and foot were also found inside the apartment. (In the "video" we see one arm with hand inside the fridge). All body parts apparently belong to the same victim. They have all the other videos of the 'kitten killer', and plenty of LRM's DNA inside that apartment, and on the victim's body. ITA with otto, that the pink sheets are not needed as evidence, jmo.
That's what I'm thinking. We know what was filmed by media as left behind, but we have no idea what was collected as evidence. I think it's a mistake to assume that police failed to collect evidence simply because things were left in the apartment. After seeing what Aruba, the Netherlands and Italy have been through in terms of criticism for having a different judicial system, I get a bit scared when I read criticisms of the Canadian system. It's different from the US system in almost every way, but it's not inferior.
