Robin Commits Suicide

Robin Williams has committed suicide.

The Oscar-winning actor/comedian killed himself in Tiburon, in Northern California.  

According to the Marin County Sheriff's Office ... authorities found Williams' body inside his home.  They say he was found unresponsive.

He was unconscious and not breathing and the coroner suspects suicide due to asphyxia.


Williams was last seen alive at his house at 10 PM Sunday night.

Robin went back to rehab last month to focus on his sobriety.  We're told alcohol was an issue.

Williams struggled with cocaine and alcohol abuse in the early '80s but was sober for 20 years ... with the exception of a stint in rehab in 2006.

One of Robin's last public appearances was at the San Francisco Zoo in June ... when the zoo named one of their howler monkeys "Robin" in his honor.

Robin's wife, Susan Schneider, says, "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."

RIP Robin.
