SAN RAFAEL, Calif. (AP) — Robin Williams committed suicide by hanging himself with a belt at his San Francisco Bay Area home, sheriff's officials said Tuesday.
Marin County Sheriff's Lt. Keith Boyd said Williams' personal assistant found the actor Monday in a bedroom at his Tiburon home. The actor also had superficial cuts on his wrist, and a pocketknife was found nearby.
Boyd said Williams, star of "Good Will Hunting," ''Mrs. Doubtfire," ''Good Morning, Vietnam" and dozens of other films, was seeking treatment for depression. He would not say whether the actor and comedian left a suicide note.
The 63-year-old comedian's wife had last seen him the night before and had left the home that morning thinking he was still asleep. His personal assistant later came to the home and became concerned when he knocked on the door and got no response.
Toxicology test results on whether Williams had any drugs or alcohol in his system are weeks away. Boyd said authorities will continue to investigate his death.
The actor had periodic bouts of substance abuse and depression for years. Just last month, Williams announced he was returning to a 12-step treatment program.
