I didnt see that in any news accounts. Seems highly unlikely that our tin-foil amateur sleuths would have any such first hand knowledge so I would be very suspicious. Most likely something that some one thought might sound good but is not true.
What I read was the autopsy was iniated when the official who initially ruled it a suicide found out from all the press inquiries that this was somebody that there was goign to be a lot questions about. The Medical Examiner has now, following a complete autopsy, ruled the death a suicide.
