Robin Williams passed away Monday morning at age 63. The Oscar-winner and comedic actor had 40 years in the industry, and a long history with depression and demons. His rep released a statement on his behalf, though will not confirm if the death was a suicide.

"Robin Williams passed away this morning. 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," it read.

The Marin County Coroner's Office suspects the death stems from "suicide due to asphyxia."

Fox released their own statement regarding Williams' passing.

"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," they said.

The "Mrs. Doubtfire" actor opened up in the past about his struggles with cocaine. He felt the drug "was a place to hide. Most people get hyper on coke. It slowed me down."

He announced his sobriety in 1986 during his one-man show at the Metropolitan Opera, and he managed to stay clean for 20 years. Williams relapsed in 2006 and entered rehab in 2010.

"It's trying to fill the hole. It's fear," the "Aladdin" star told Mark Maron.  "You're kind of going, 'What am I doing in my career? ... Where do you go next?'"

Williams reiterated these thoughts in a 2008 interview with The Guardian.

"You know, I was shameful," the star confessed. "You do stuff that causes disgust, and that's hard to recover from. You can say, 'I forgive you' and all that stuff, but it's not the same as recovering from it."
