I suspect he fainted and fell over when he found out that a autopsy was required for anyone to be cremated. In his effort to destroy the evidence, he stupidly stumbled into his own undoing. Psychopaths are by nature stupid.
I don't think so. If he didn't think he'd get a favorable autopsy, he could simply have removed the body from the state for a Pennsylvania burial, and then once the body was out of Florida cremated it there (or in some 'friendly' state).
I just hope you are right. Unfortunately, as stupid as MS is, he has a very smart lawyer who has connections in his death club and knows how to "fix" things.
