The rumor is that it wasn't suicide. It was auto-erotic asphyxiation gone wrong. He had been drinking and drugging heavily the entire night with friends. They left and then he decide to 'get off'. He was hanging from the door knob when the maid found him. I think he passed out while masturbating.
There's also this story:
Other contributed dirt:
Michael Hutchence didn't commit suicide. Paula's claims that he died of 'sexual misadventure' were accurate. The police found him with a belt around his neck and a broom handle up his ass. The whole auto-erotic asphyxiation thing. He had slipped and it was either impale himself or strangle. Out of respect for his family (because it was such a embarrassing way to die), the police called it a suicide and the press simply didn't want to touch the story with a ten-foot cattleprod. I got the story from an Australian policeman who was at the scene and it was confirmed by my ex, an Australian journalist that it was, indeed, tragic (and a bit gross) but true.
