Oscar-winning actor and comedian Robin Williams was found dead on Monday from an apparent suicide.
The Marin County Sheriff's Office said that the actor, who was 63, was found dead at his home in Northern California.
The sheriff's coroner's division said it suspected the death was a suicide due to asphyxia, but the cause of death is still under investigation. An autopsy will be conducted on Tuesday.
Williams, who starred in "Mrs. Doubtfire," "Good Will Hunting" and many other hits had struggled with addiction in the past. Last month, he entered a Minnesota rehabilitation center to help him maintain sobriety.
His representatives at the time said Williams was not using drugs or alcohol but had gone to the center to "fine-tune and focus" his sobriety after working a longer-than-usual schedule.
Williams had been battling severe depression recently, his publicist, Mara Buxbaum, said in a statement.
“This is a tragic and sudden loss,” the statement said. “The family respectfully asks for their privacy as they grieve during this very difficult time.”
Reacting to WIlliams' death, United States President Barack Obama said: "Robin Williams was an airman, a doctor, a genie, a nanny, a president, a professor, a bangarang Peter Pan, and everything in between. But he was one of a kind. He arrived in our lives as an alien – but he ended up touching every element of the human spirit. He made us laugh. He made us cry. He gave his immeasurable talent freely and generously to those who needed it most – from our troops stationed abroad to the marginalized on our own streets. The Obama family offers our condolences to Robin’s family, his friends, and everyone who found their voice and their verse thanks to Robin Williams."
Williams' appeal stretched across generations and genres, from family fare as the voice of Disney's blue Genie in "Aladdin" to his portrayal of a fatherly therapist in the 1997 drama "Good Will Hunting," for which he earned his sole Oscar.
But many remembered the master of impressions on Monday for his portrayal in "Mrs. Doubtfire", when he played the part of a British nanny whose identity he assumed as a divorced father to be with his children.
"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' wife Susan Schneider said in a statement.
