SAN RAFAEL, Calif. -- Sheriff's officials near San Francisco say Robin Williams committed suicide by hanging himself with a belt at his home.
A sheriff's lieutenant says Williams' personal assistant found the actor yesterday in a bedroom at Williams' home. Williams also had superficial cuts on his wrist, and a pocketknife was found nearby.
According to Sheriff's Lt. Keith Boyd, Williams had been seeking treatment for depression. Boyd isn't saying whether Williams left a suicide note.
The actor's wife had last seen him the night before, and had left the home that morning thinking he was still asleep. Williams' personal assistant later came to the home and became concerned when he knocked on the door and got no response.
It will take weeks to get the results of toxicology tests on whether Williams had any drugs or alcohol in his system.
Fans and friends have been leaving bouquets, candles and personal notes in front of the locked gates of the home. Neighbors say he had lived in the quiet, waterfront neighborhood for eight years, and that he was friendly and approachable.
Coroner's officials say he was last seen alive at home around 10 p.m. Sunday.
Oscar-winner Robin Williams, whose free-form comedy and adept impressions dazzled audiences for decades, has died in an apparent suicide. He was 63.
The Marin County Sheriff's Office says Williams was pronounced dead at his home in California on Monday. The sheriff's office says a preliminary investigation shows the cause of death to be a suicide due to asphyxia.
Williams shot to fame in the late `70s as the alien in TV's "Mork and Mindy." He conquered the big screen in comic films such as "Good Morning, Vietnam" and "Mrs. Doubtfire." But he won his Academy Award in a serious role -- as the therapist in "Good Will Hunting."
His performing style was at its purest in his standup act, as he impersonated a Russian immigrant or parodied anyone from John Wayne to Keith Richards.
