Lead vocalist of rock band Linkin Park, Chester Bennington's autopsy report has been revealed by the Los Angeles County Coroner's Office on Tuesday, Dec. 5. It was found out that Bennington was not under the influence of drugs, but had a small amount of alcohol in his body when he died.

The autopsy report reveals that the authorities found a bottle of the prescription medicine Zolpidem, a generic brand of Ambien -- a sedative used to cure sleeping problems. They also saw a pint glass of Corona and an empty bottle of Stella Artois.

Thus, Bennington had alcohol in his system when he committed suicide. He was also "presumptive positive" for the use of ecstasy. However, his two urine tests tested negative and did not detect the drug. This means that he did not take drugs prior his death.

Additionally, fingernail fragments were seen beneath the singer-songwriter's iPhone and on his bedside table. According to his widow, Talinda Bennington, this was his late husband's "anxious habit."

To recall, Bennington died by hanging himself inside his California mansion on July 20. This happened two weeks after his performance in Birmingham's Barclaycard Arena, which was also his last live performance.

He was discovered lifeless when his maid was about to tell him that his Uber driver had arrived. The hitmaker was seen shirtless, with unbuttoned blue jeans and black underwear underneath. His boarding pass from his flight earlier that day was still in his pocket.

Talinda revealed that Bennington really had suicidal tendencies when under the influence of alcohol. In fact, he tried to commit suicide in 2006 when he held a gun in a drunken rage. She also reported that her spouse was in an outpatient treatment program and had been sober for six months.

Although there was no suicide note found at the time of his death, an "apparent biography" was seen in his room. This is believed to be written by Bennington himself.
