Lil Peep’s brother has revealed that his death was an accident.

The 21-year-old rapper - real name Gustav Ahr - passed away this week on November 15 after he was found dead on his tour bus following a suspected drug overdose. 

The Pima County Office of the Medical Examiner has now confirmed the suspected cause of death to be a drug overdose. It will be six to eight weeks for toxicology results to determine a definitive cause of death.

The rapper’s brother Karl Åhr says that the drugs he took may have been laced with another substance.

“We [the family] have heard there was some sort of substance he did not expect to be involved in the substance he was taking."

He denied the possibility of an intentional overdose, saying: “It was an accident, it really was an accident. He was super happy with where he was in life.

“He was so proud when he heard that there were people in the world who wanted to kill themselves, and then they didn’t because they listened to his music.

“He was helping people, he was not somebody who needed help. He was not as sad as people think he was. It’s frustrating as someone who remembers a happy brother.”
