Robin Williams’ autopsy reveals he was not under influence of alcohol or drugs at time of suicide

Robin Williams’ autopsy report has revealed that the actor was not under the influence of drugs or alcohol at the time of his suicide.

Robin Williams was found dead in his California home on August 11 in what authorities soon ruled a suicide. He was 63.

A Marin County coroner’s report released on Friday found Williams died from asphyxia due to hanging.

Robin Williams had been treated for depression.

He was last seen alive by his wife, Susan Schneider, on August 10, and was found dead the following day.

On the morning Robin Williams was found, the actor’s personal assistant became concerned when he did not respond to knocks on the door, authorities say. The assistant entered the room and found Robin Williams dead.

Robin Williams won an Academy Award for his role in Good Will Hunting and starred in films including Good Morning Vietnam and Jumanji.

In the past the actor had talked, and even joked, about his struggles with alcohol and drugs. After his death, his representative said he had also been “battling severe depression”.

Robin Williams had earlier returned to a rehabilitation centre to “fine-tune” his sobriety, the Los Angeles Times reported in July.
