It's a MURDER cover up!!!
I could be wrong, but I would think it would take several people to subdue someone of his size/strength in order to hang him. Clearly if they fed him something first it'll show in an autopsy, but barring that, getting "several" people to keep quiet forever I'd have a hard time buying. I honestly think that visit by his daughter (bad move, really bad move) pushed him over the edge.
