Robin Williams‘ death was determined to be a suicide, according to a statement from the coroner’s office in Marin County, Calif.
The cause of death was asphyxia due to hanging. No illegal drugs or alcohol were found in his system. Prescription medications were detected in therapeutic concentrations.
Williams was found dead at age 63 at his home in Tiburon, Calif. on August 11.
The actor’s body was discovered in a bedroom of his home with one end of a belt secured around his neck and the other wedged between the closed closet door and the door frame.
Williams was celebrated by friends and family for bringing “so much happiness and light” in a private tribute held in September. Among the hundreds who attended the Curran Theatre event, hosted by Billy Crystal, were his widow Susan Schneider Williams and his children Zak, 31, Zelda, 25 and Cody, 22. George Lucas, Bette Midler, Jeff Bridges, Ben Stiller, Penny Marshall, Sarah Michelle Gellar and his “Mork and Mindy” co-star Pam Dawber were among the industry figures in attendance.
The “Good Will Hunting” Oscar winner broke through in show business with the sitcom “Mork & Mindy,” and won the hearts of audiences in memorable roles such as “Dead Poets Society,” “Good Morning Vietnam” and “Mrs. Doubtfire.”
