Robin Williams hanged himself with a belt after his wife had gone to sleep Sunday night.
Those are among the graphic new details to emerge about the death of the 63-year-old entertainer at a press conference Tuesday.
Speaking from prepared notes, Marin Sheriff's Lt. Keith Boyd said that Williams's wife, Susan Schneider, went to bed at 10:30 p.m. on Sunday. Williams later retired in a different bedroom of their home in Tiburon, California, a small town in the San Francisco Bay area.
In the morning, Schneider left the home, thinking Williams was still sleeping. His assistant later came to the house and, concerned about the actor, went into the bedroom and discovered his lifeless body at about 11:45 a.m.
Williams died as a result of death by asphyxia, said Boyd. The actor was partially clothed and suspended from a belt that was wedged between a closet door and the door frame. The assistant told officials he was cold to the touch and rigor mortis had begun to set in. The iconic comedian was pronounced dead at 12:02 p.m. Monday.
Williams's wrist also had several acute superficial wounds on his left wrist thought to be from a pocket knife that was found nearby. His body was transported to Napa County Sheriff's Morgue for the autopsy, which took place Tuesday morning.
Boyd would not confirm whether a note was left behind nor would he reveal whether it was Williams's first suicide attempt. He did state that Williams was being treated for depression. And authorities had not been called to the home for previous incidents.
