In a shocking development, Oscar-winning actor/comic Robin Williams was found dead in his California home Monday, a possible suicide, according to investigators. He was 63.
The Marin County Sheriff's Office said Williams was found unconscious and not breathing inside his home in Tiburon, Calif., around noon local time, and was pronounced dead shortly after. Tiburon is across the Golden Gate Bridge north of San Francisco.
The county coroner suspects the death was "a suicide due to asphyxia," which could mean death by hanging. But a comprehensive investigation must be completed before a final determination is made; an autopsy is scheduled for Tuesday, the press release said.
Williams' rep confirmed the death to USA TODAY.
"Robin Williams passed away this morning," said Mara Buxbaum, president of his PR firm. "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."
His wife, Susan Schneider, issued a brief statement: "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," she said.
The news of his death sent shock waves through Hollywood and the nation, and prompted an outpouring of grieving tweets and statements from everyone from the President of the United States to the Sesame Street gang.
"Robin Williams was an airman, a doctor, a genie, a nanny, a president, a professor, a bangarang Peter Pan, and everything in between," President Obama said in a statement. "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."
CNN reported a statement from Pam Dawber, Williams' co-star in the wacky Mork & Mindy of the late 1970s. "I am completely and totally devastated. What more can be said?!"
"We mourn the loss of our friend Robin Williams, who always made us laugh and smile," the Sesame Street tweet read.
Williams' last tweet and Instagram was on July 31, when he wished his daughter, Zelda Rae, a happy 25th birthday and posted a picture of himself with her. "Quarter of a century old today but always my baby girl," he captioned the photo.
Williams will reprise his role as Theodore Roosevelt in the third Night at the Museum film. Fox issued a statement, according to Entertainment Weekly.
"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."
Williams, who won an Oscar for his supporting role in Good Will Hunting, also recently signed on to reprise his beloved role as Mrs. Doubtfire in a sequel to be directed by Chris Columbus, according to EW.
