Robin Williams Documentary Explains Actor's 'Very Paranoid" Behavior in His Final Hours

When news broke that award-winning actor Robin Williams hanged himself at his own home in Tiburon, California last year, the world put forward numerous questions regarding his battle with substance abuse.

At 63 years old, the movie star was thought to have been overcoming his struggle against alcohol and drugs. It was eventually reported that, aside from his depression, the actor was recently diagnosed with Lewy body dementia (LBD), a cross between dementia and Parkinson's disease.

Now, a documentary titled "Autopsy: The Last Hours of Robin Williams' helmed by pathologist Richard Shepherd seeks to explore Williams' autopsy results along with his final hours in order to determine the underlying reasons for his suicide.

Following the initial claims that the actor's suicide can be attributed to his psychological state, the documentary looks into the rare brain disease that may have caused the actor to take his own life.

Aired on UK TV's Channel 5, the documentary also showed interviews that were carried out with some of Williams' closest pals and biographers.

After the autopsy ascertained that the actor died from asphyxia due to hanging, it was noted that superficial cuts had been made to his wrists and that a pocket knife was found near his death scene.

According to the documentary, Williams took some time to clean up his own blood in his bathroom after cutting his wrists following several hours of strange behavior. It also claims that the Oscar-winning actor had been having a peculiar episode before he killed himself.

As pointed out by Susan Schneider, her husband was acting in a "very paranoid" manner when he placed all of his watches into a sock and enlisted the help of a friend to keep watch over his collection.

After leaving his watches, Williams reportedly spent his final hours searching for drugs online as he was convinced that he was suffering from more than just insomnia and anxiety.

Williams is survived by his wife Susan and his three children- 31-year-old Zak, 25-year-old Zelda and 23-year-old Cody. While Zak is the actor's son from his first wife Valeria Velardi, Cody is his son from his second wife Marsha Garces.

 Aside from the "Mrs. Doubtfire' star, deaths of other celebrities have also been investigated by Dr. Shepherd. These include the King of Rock and Roll, Elvis Presley, as well as '70s singer Karen Carpenter.
