A preliminary investigation has concluded that beloved comedian Robin Williams died of suicide by asphyxiation, authorities in Marin County, California have confirmed. The Mrs. Doubtfire actor was found in his home on Monday morning by his personal assistant who called 911.
Lt. Keith Boyd, assistant deputy chief coroner of the Marin County Sheriff's Office revealed that Robin was confirmed dead by paramedics at 12.02pm, and added that toxicology results and a full forensic examination will be available in two to six weeks.
He also confirmed that Robin's wife Susan Schneider was the last person to see the 63-year-old Oscar winner on Sunday evening.
Robin's representative said in an official statement on Monday that the star had been battling severe depression, before adding: "This is a tragic and sudden loss. The family respectfully asks for their privacy as they grieve during this very difficult time."

His wife of nearly three years, Susan, released the following statement to the New York Times: "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 that the focus will not be on Robin's death but on the countless moments of joy and laughter he gave to millions."
Robin had been candid about his battle with alcohol and substance abuse in the past and checked into a treatment facility to "focus on his commitment" to overcome his addictions in July.
He began his career as a stand-up comedian, but went on to become a celebrated film actor who excelled in both comedic and dramatic roles. Some of his most memorable films include Mrs. Doubtfire, Dead Poet's Society, Aladdin, and Hook, and in 1998, Robin won an Academy Award for Best Supporting Actor for his role in Good Will Hunting.
