The investigation into Robin Williams’ death has been concluded. In a statement on Friday, the Marin County Coroner’s Office ruled his death a suicide by hanging, adding that no alcohol or illegal drugs were involved.
Prescription medications were detected in “therapeutic concentrations,” the statement read.
The Oscar winner was found dead on Aug. 11 at the age of 63. In a statement at the time, Williams’ rep said the actor had been suffering “severe depression” before his death. His wife, Susan Schneider, later released a statement saying that while her husband was sober, “he struggled with his own battles of depression, anxiety, as well as early stages of Parkinson’s Disease, which he was not yet ready to share publicly.”
“It is our hope in the wake of Robin’s tragic passing, that others will find the strength to seek the care and support they need to treat whatever battles they are facing so they may feel less afraid,” she wrote.
