Lil Peep's cause of death has been revealed.
The up-and-coming rapper (real name Gustav Åhr) died at the age of 21 last month from the combined toxic effects of fentanyl and alprazolam (Xanax), ET can confirm.
According to his toxicology report, obtained by ET from The Pima County Office of the Medical Examiner, the manner of death is certified as accidental. The report also reveals there were a number of other drugs in his system, including marijuana, cocaine, Hydrocodone, Hydromorphone (Dilaudid), Oxycodone and Oxymorphone.
As ET previously reported, Lil Peep was found unresponsive in his tour bus prior to a scheduled concert in Tucson, Arizona, on Nov. 15. His death came three months after he released his debut album, Come Over When You’re Sober, Pt. 1.
"I am shocked and heartbroken. I do not believe Peep wanted to die, this is so tragic," Sarah Stennett, CEO of First Access Entertainment, the company who partnered with Peep in early 2016 told ET in a statement at the time. "He had big goals and dreams for the future which he had shared with me, his team, his family and his friends. He was highly intelligent, hugely creative, massively charismatic, gentle and charming. He had huge ambition and his career was flourishing."
"I have spoken to his mother and she asked me to convey that she is very, very proud of him and everything he was able to achieve in his short life," Stennett added. "She is truly grateful to the fans and the people who have supported and loved him."
