To be honest, no. If the hiding theory was true, i think he'd have slipped up and been found bởi now- Let's face it- bạn couldn't really miss him if bạn saw him out & about. but it would been nice were it true.
They showed him on TV in his coffin. He was pale(not that that's a difference, anyways, but I'm trying to prove a point). Why would they make something up like that? That's morbid. This is just like saying Elvis is still alive. -.- They're dead, get over it.
