Looks like it will be a few weeks before we know the cause. They just said that he was found dead in his hotel room after he did not respond to a wake up call.
I heard on the news that his autopsy was scheduled for Monday 11/14/05. I is very sad, especially when he and his nephew were talking about his 4 year anniversary of sobriety on the flight to minneapolis. Whatever happened I hope that it was quick and painless.
