How did he die? Heart attack? AIDS? Suicide?
If I were a betting man, I would put my money on drug overdose of some kind. But it makes sense that it would be from a heart condition. I haven't seen any recent pictures of him but I would guess he was still using gear, too. At 60 ? Whatever years old, years of juicing, years of recreational drug use... the ticker can only take so much before it gives out.
