In a shocking turn of events, beloved actor Robin Williams has committed suicide. He was 63 years old.

The Marin County Sheriff's department has released a statement saying the actor killed himself by asphyxia at his home in Tiburon, Northern California.

According to the Marin County Sheriff's Office, authorities were called to his home but found Williams unresponsive, unconscious and not breathing. The statement said that the office received a 9-1-1 call at 11:55 a.m. saying that a man had been found unconscious and not breathing inside his residence. Emergency personnel sent to the scene identified him as Mr. Williams and pronounced him dead at 12:02 p.m.

Although his publicist wouldnt confirm that it was indeed a suicide, his rep issued a statement, Robin Williams passed away this morning. He has been battling severe depression of late. This is a tragic and sudden loss. The family respectfully asks for their privacy as they grieve during this very difficult time.

Williams was starring in a third installment of FOX's Night at the Museum film. The studio issued the following statement: There really are no words to describe the loss of Robin Williams. He was immensely talented, a cherished member of our community, and part of the Fox family. Our hearts go out to his family, friends and fans. He will be deeply missed.

The Oscar winner, who has publicly struggled with addiction for decades, checked himself into a rehab last month to focus on his sobriety.

Williams was a beloved comedic actor who also garnered critical acclaim (and the Academy Award) for his dramatic work. Some of his most loved movies include Mrs. Doubtfire, The Birdcage, Dead Poets Society, Good Morning, Vietnam and Good Will Hunting, the film that won him the Oscar.
