It's obvious that he was murdered. Too bad we will never find out who the murderer was.

Really liked him.

Michael was the cause of his own death. They just sped up the process. Sooner or later he was going to die being on that stuff, and they knew it. So they cashed in on it. Manslaughter is more like it.

They didn't pull the plug, they just help enable him. They knew by enabling him instead of helping him he'd die and they'd control all of the estate. Nothing to do with Illuminati, just all to do with cash.
