He's not dead, it was a mistake from the media.
Unless his wife is still in denial when she claims he's still alive and kicking. If not, we have quite the medical phenomenon, and the first zombie should be studied closer.
edit; nvm, I read that article, and its a new one.
So first she changed her mind stating he's still alive, and then she goes out and say that he really did die? >.> Must be horrible to say to the media that they lie and that he's still alive, only to hours later confirm that he did indeed die.
