Robin Williams' untimely death on Aug. 11 has been ruled a suicide due to depression, Parkinson's disease and paranoia, the Marin County, Calif. coroner announced in a statement this afternoon.
The discovery that the iconic comedian was suffering from paranoia has not been previously reported.
According to the newly released report, the night before Robin passed away, he placed several wristwatches in a sock and gave them to someone because he was worried about their safe keeping.
Alcohol and illegal drugs were not involved in his death, however, prescription drugs were found in "therapeutic concentrations" in the actor's body, the statement said.
A closed bottle of Seroquel — a drug used to treat Schizophrenia, bipolar disorders and depression — was reportedly found near the actor's body. It was later determined the he obtained a prescription for the medication a week before he died from asphyxia due to hanging.
The report also noted Robin's last outgoing call from his phone was to his wife, Susan Schneider, at 7:08 p.m. the night before he died. She told authorities he called because he was picking up magazines for her at a local bookstore.
The night before his passing, Robin's wife revealed he seemed his usual self. He had even grabbed his iPad from their closet, which she deemed to be a good sign because he hadn't watched TV or read a book in approximately six months, the report stated.
The iPad's web browser allegedly proved to have several pages open to websites with information about medications that treat blood pressure and tremors.
Susan reportedly last saw her husband at about 10:30 p.m. on Aug. 10 and described his demeanor as "excited."
Following his death, she revealed the 'Mrs. Doubtfire' star had been dealing with the early stages of Parkinson's disease.
