Robin Williams, a beloved movie and television star who made his return to the small screen just last year in The Crazy Ones, has been found dead.

He was 63 years old.

According to The Marin County Sheriff's Office, authorities responded to a 911 call just before noon and arrived at the scene to find Williams' body. The actor was unresponsive and not breathing.

A coroner suspects suicide due to asphyxia, while forensic tests are scheduled for tomorrow, with subsequent toxicology testing to be conducted as well.

Williams starred in countless hit movies and won an Academy Award for his work in Good Will Hunting.

But he got his big break on TV via the sitcom Mork & Mindy and starred opposite Sarah Michelle Gellar for one season in The Crazy Ones until CBS canceled the series this spring.

Our thoughts go out to his loved ones.

UPDATE: The star's rep has released a statement that reads:
