Monday night, the nation was rocked by news of the death of Robin Williams, beloved comic and actor. On Tuesday, officials at the Marin County sheriff's department confirmed that the actor committed suicide by asphyxiation in his home in Tiburon, California. He was 63 years old.

According to his press agent Mara Buxbaum, Williams privately struggled with depression. The actor publicly struggled with addiction, often drawing on his experiences with cocaine in candid and frenetic standup routines, but had been sober 20 years before seeking treatment for alcohol abuse in 2006. Williams entered rehab in early July 2014 to "fine-tune and focus on his continued commitment" to sobriety, Huffington Post reported at the time.

You remember Williams from classic movies like Good Will Hunting, Jumanji, Dead Poets Society, Mrs. Doubtfire, Aladdin, and more. Details of his death, from the Los Angeles Times:
