Chester Bennington's autopsy revealed the Linkin Park singer had alcohol in his system when he committed suicide, and perhaps the drug ecstasy, TMZ reported, citing autopsy and toxicology reports.
While one test resulted in a "presumptive positive" for ecstasy in the 41-year-old singer's system, two other tests did not find the drug, according to the reports, per TMZ, leading authorities to rule he was not affected by drugs at the time of his death.
Bennington died July 20 from hanging himself. He suffered from a history of depression and had attempted suicide in the past, TMZ said, and he had told a friend he had been sober for six months.
His wife Talinda Bennington had said her husband was in an outpatient treatment program, TMZ noted.
Ryan Shuck, a longtime friend of Bennington who played with him in the band Dead by Sunrise, told Rolling Stone magazine the singer sent him text messages before his death about his struggles.
"He was describing an hour-by-hour battle with addiction," Shuck told the magazine. "When I look at it now, it's horrifying. He was telling me, down to the detail, what he would do in the first hour he wanted to drink: 'I basically just take it hour-by-hour every day.'"
Bennington talked about his constant battle with addiction back in February on Los Angeles' iHeartRadio's KIIS-FM, noted Blabbermouth.net.
"I don't know if anybody out there can relate, but I have a hard time with life… sometimes," Bennington said in the interview that was posted on YouTube. "Sometimes it's great, but a lot of times for me, it's really hard. And no matter how I'm feeling, I always find myself struggling with certain patterns of behavior… I find myself stuck in the same thing that keeps repeating over and over again, and I'm just, like, 'How did I end up…? How am I in this?'"
TMZ reported that Bennington did not leave a suicide note but authorities did find what seemed to be a handwritten "biography."
