Legendary comedian and actor Robin Williams killed himself using a belt, and appears to have slit his left wrist sometime between Sunday night and Monday morning, authorities announced Tuesday afternoon.
Police Lt. Keith Boyd said Williams, 63, was slightly suspended in a seated position with a belt wrapped around his neck. The other end of the belt was attached to a door, Boyd said.
A distraught 911 call was received shortly before noon Monday, Boyd said. Upon arrival officer discovered Williams, who was clothed, cool to the touch and in a state of rigamortis.
Williams had "several cuts" to his left wrist, and a pocket knife with a closed blade was located nearby, Boyd said. The blade had a red substance on it that may be blood, Boyd said, though tests are being done to determine if the substance is in fact blood, and if it belonged to Williams.
"He was suspended… from the belt which was wedged between a door and the door frame in a seated position," Boyd told reporters in San Rafael around 2 p.m. Tuesday.
There did not appear to be any signs of a physical altercation, Boyd said, and the evidence is consistent with a suicide.
An autopsy was conducted following the death, Boyd said, and the officials cause of death was "asphyxiation due to strangulation."
Boyd would not comment on whether a note was found at the scene, and he declined to specify which room in the house Williams was located.
Williams was last seen by his wife around 10:30 p.m. Sunday night. She left the home Monday morning assuming Williams was sleeping. Williams' assistant became concerned when he did not respond to knocks on the door. The assistant was able to gain entry into the room, Boyd said, and found Williams. He was pronounced dead shortly after noon Monday.
A toxicology test will be conducted to determine whether Williams had any chemical substances in his system. Boyd said those results could take weeks.
