A Marin County sheriff's official on Tuesday offered the most detailed description of the death of Robin Williams, whose body was "cool to the touch" when it was discovered by a personal assistant.
Rigor mortis had already set in by the time Williams' assistant discovered the body in a slightly elevated position with a belt around the neck, said Lt. Keith Boyd, assistant deputy chief coroner in the Sheriff's Office.
The distraught assistant, whose name was not released, called 911 at 11:55 a.m. Monday to report the discovery.
Williams, 63, also had recent but superficial cut marks on his left wrist. A pocket knife was found near his body, with a dried substance resembling blood.
In front of a bank of media cameras, Boyd offered the most detailed statement yet on the death of the Oscar-winning actor and comedian at his home in unincorporated Tiburon.
Boyd declined to say whether Williams had left a note, but he said Williams had been receiving "treatment for depression" and confirmed that suicide was suspected. Boyd wouldn't answer questions about any prior suicide attempts or the treatment Williams was receiving for depression.
Toxicology tests, which are expected to take two to six weeks, will reveal whether Williams had any alcohol or drugs in his system, Boyd said.
Williams and his wife, Susan Schneider, were alone Sunday night in their home, which fronts San Francisco Bay, Boyd said. Sheriff's officials had previously said Williams was last seen at 10 p.m., but Boyd said Schneider retired to a bedroom at 10:30 p.m.
It was not known when Williams went to bed in a separate bedroom.
Schneider left home at 10:30 a.m. the next day, believing her husband was OK, Boyd said. At 11:45 a.m., the personal assistant became concerned when Williams failed to respond to knocks at his door, Boyd said.
When the assistant entered, Williams was unresponsive, "clothed" and "cool to the touch," Boyd said. The belt was wedged between the closet door and the door frame, Williams' right shoulder was touching the door and his body was "slightly suspended," as though in a seated position.
Tiburon Fire Department personnel pronounced Williams dead at 12:02 p.m., Boyd said. Due to concerns about photos being taken or released, his body was taken to Napa County for an autopsy, Boyd added.
Preliminary results of the forensic exam indicate the cause of death was "asphyxia due to hanging," Boyd said. A time of death has yet to be established.
The department will hold another news conference when the autopsy results are finalized.
