I still think it's a bunch of BS that the cuffs were arround her neck. Think about that for a moment. What possible situation could you put your arms in that would get them to neck height and that's it? I'm sitting here imagining myself with cuffs on both behind me and infront of me. There is no position I can put myself in where the cuffs would be able to strangle me. They always hold your wrist together, if anything maybe and inch or two apart, and I still can't come up with anything.
I'm guess is the media is completely wrong. Heart attack, seziure, stoke, aneurysm, etc. If she was screaming then all the sudden stopped I doubt she was sitting there twisted like a pretzel trying to get cuffs off. Be hard to scream like that.
