Beloved actor Robin Williams died at the age of 63 on Monday, authorities and his wife have confirmed.

Police were the first to announce the death of Williams, who was discovered “unconscious and not breathing inside his residence” in Tiburon, California. A police report was the original source of the announcement.

“The Sheriff’s Office Coroner Divison suspects the death to be a suicide due to asphyxia,” the report stated.

Williams wife Susan Schneider issued a statement shortly after police released theirs. “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 the focus will not be on Robin’s death, but on the countless moments of joy and laughter he gave to millions.”

Said his publicist in a separate statement today, “He has been battling severe depression of late. This is a tragic and sudden loss.”

An investigation into his death is now underway.

Update: Hollywood is reacting to the death of Williams. Read tweets from the stars about the passing of their friend and fellow actor.

Update 2: President Obama has issued a statement. “Robin Williams was an airman, a doctor, a genie a nanny, a president, a professor, a bangarang Peter Pan, and everything in between,” he said. “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.”

In July the actor had checked himself into rehab after troubles with alcohol. A statement from his rep to TMZ at the time said, “After working back-to-back projects, Robin is simply taking the opportunity to fine-tune and focus on his continued commitment, of which he remains extremely proud.”

Williams is best known for roles in Good Will Hunting, Dead Poets Society, Aladdin, Mrs. Doubtfire, and Jumanji.

More recently, the actor starred on CBS’ The Crazy Ones.
