Robin Williams, the Oscar-winning actor and stand-up comedian who's lived for many years in the San Francisco Bay Area, was found dead in his Tiburon, California home on Monday, as the Marin Sheriff's Department is reporting.

The Sheriff's Department issued a release Monday, August 11, saying that they are currently investigating Williams' death, but that the county coroner "suspects the death to be a suicide due to asphyxia." Williams was reportedly last seen by his wife around 10 p.m. on Sunday, and could not be found in the home this morning. He was then found and reported unconscious and not breathing at 11:55 a.m.

The Marin Independent Journal notes that Williams, a recovering alcoholic and cocaine addict, had recently gone back for treatment in a rehab facility. As of July 1, he was checked into the Hazelden Addiction Treatment Center near Lindstrom, Minnesota, and it was at a nearby Dairy Queen that an employee posted the photo below to Facebook. It may be one of the last known photos of the actor. It's not clear how long Williams had been back home in Tiburon.

Williams' death comes six months after the drug-related passing of actor Philip Seymour Hoffman, who had also fallen off the wagon in his struggle with heroin addiction. People on social media have been quick to post the video clip below, from 1998's Patch Adams, of a scene with Hoffman and Williams.

Williams' wife Susan Schneider issued a statement as well, saying: "This morning, I lost my husband and my best friend, while the world lost one of its most beloved artists and beautiful human beings. I am utterly heartbroken. On behalf of Robin's family, we are asking for privacy during our time of profound grief. As he is remembered, it is our hope the focus will not be on Robin's death, but on the countless moments of joy and laughter he gave to millions." [Hollywood Reporter]
