"At this time, the Sheriff’s Office Coroner Division suspects the death to be a suicide due to asphyxia, but a comprehensive investigation must be completed before a final determination is made," the Marin County Sheriff’s Office-Coroner Division said in a press release. "A forensic examination is currently scheduled for August 12, 2014 with subsequent toxicology testing to be conducted."
Williams won a Best Supporting Actor Academy Award for his role in "Good Will Hunting," and was planning to film a sequel to his hit comedy "Mrs. Doubtfire."
According to NBC Bay Area, Williams' wife Susan Schneider said in a statement, "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."
Williams, who openly admitted to drinking and drug problems, mentioned last month that he might enter a 12-step treatment program in Minnesota.
