Michael was an addict for years so dying of some overdose isn't surprising. I was reading that he had been telling his close friends that he wanted to die, he didn't feel he could cope after the accusations of child molestation came out.
The only ones I can feel sorry for here are those poor kids - God help them if they fall into the hands of Joe Jackson. He's the real devil's advocate here and if not for him MJ might still be alive.
