Robin Williams was last seen by his wife about 10:30 p.m. Sunday when she went to bed, and his body was found by his personal assistant about 11:45 a.m. Monday, according to the Marin County Sheriff's Office.
The Sheriff's Office said in a news conference Tuesday afternoon that Williams was found hanging from a belt that he had secured between a door and a door frame and that rigor mortis had set in, possibly indicating he'd been dead for some time.
The Sheriff's Office said Williams also had cuts on the inside of his wrist but the preliminary cause of death is considered asphyxia by hanging.
Lt. Keith Boyd refused to comment on whether Williams left a suicide note or whether there was evidence of alcohol or drug use in the home.
Statement from the Marin County Sheriff's Office:
On August 11, 2014, at approximately 11:55 am, Marin County Communications received a 9-1-1 telephone call reporting a male adult had been located unconscious and not breathing inside his residence located at 95 St. Thomas Way in unincorporated Tiburon, CA. The caller was distraught and indicated an apparent suicide due to a hanging had taken place and rigor mortis had set in.
The Sheriff's Office, as well as the Tiburon Fire Department and Southern Marin Fire Protection District were dispatched to the incident with emergency personnel arriving on scene at 12:00 pm. The male subject, pronounced deceased by firefighters from the Tiburon Fire Department at 12:02 pm has been identified as Robin McLaurin Williams, a 63-year-old resident of unincorporated Tiburon, CA.
Preliminary information developed during the investigation by Coroner Division personnel has revealed Mr. Williams had been seeking treatment for depression. Mr. Williams was last seen alive by his wife at approximately 10:30 p.m. on August 10, 2014, when she retired for the evening in a room in the house. It is unknown at this time when Mr. Williams retired for the evening in a bedroom in his home.
At approximately 10:30 a.m. on August 11, 2014, Mr. Williams' wife left the home believing Mr. Williams to still be asleep. Mr. Williams' personal assistant became concerned at approximately 11:45 a.m. when he failed to respond to knocks on his bedroom door. At that time the personal assistant was able to gain access to Mr. Williams' bedroom and entered the bedroom to find Mr. Williams clothed in a seated position, unresponsive, and with a belt secured around his neck with the other end of the belt wedged between the closed closet door and door frame.
His right shoulder area was touching the door with his body was perpendicular to the door and slightly suspended.
Mr. Williams was cool to the touch with rigor mortis present in all of his extremities and livor mortis positioned appropriately for the position he was located in. The inside of Mr. Williams' left wrist had several acute superficial transverse cuts. A pocket knife with a closed blade was located in close proximity to Mr. Williams. The pocket knife was examined and dry red material was located on the blade which appeared consistent to dried blood. It is unknown at this time if the dried red material is in fact blood or if it is Mr. Williams' blood, but scientific testing will be conducted to evaluate its investigative value.
Mr. Williams was transported from the scene to the Napa County Sheriff's Office Morgue by the Coroner Division pending a forensic examination which was conducted this morning prior to this press conference. The forensic examination, conducted by Dr. Joseph Cohen who is the Sheriff's Office Chief Forensic Pathologist, did not reveal any injuries indicating Mr. Williams had been in a struggle or physical altercation prior to him being located deceased. The preliminary results of the forensic examination revealed supporting physical signs that Mr. Williams life ended from asphyxia due to hanging.
Toxicology testing will be conducted to determine if Mr. Williams had any chemical substances in his system at his time of death. Toxicology results will not be available for approximately two to six weeks while the testing is being performed.
Please note this is an active investigation into the cause, manner and circumstances of Mr. Williams' death. The final cause and manner of death will not be certified until the conclusion of the investigation which is several weeks away.
When the investigation is concluded and our final results are ready for dissemination a press conference will be scheduled.
