Coroner: No Booze, Drugs in Suicide of Robin Williams

The coroner in Marin County, Calif., today confirmed that Robin Williams' death was indeed caused by suicide, reports CNN. The 63-year-old had no alcohol in his system when he hanged himself at his home, and the only drugs found were from prescribed medication in "therapeutic concentrations." The coroner lists caffeine, antidepressants, and the Parkinson's drug levodopa.

That meshes with reports that Williams had been struggling with anxiety and a recent diagnosis of Parkinson's before his death. The coroner's report also reveals this odd anecdote, as relayed by the Hollywood Reporter: The night before he died, Williams put several wristwatches in a sock and gave them to somebody because he was worried about their safekeeping. TMZ sees that as a sign of paranoia. (More Robin Williams stories.)
