New details have emerged in the death of Lil Peep. Peep, whose captivating debut studio album Come Over When You're Sober Pt. 1 was released back in August, died Nov. 15 in Tucson on one of the final dates of his 2017 North American tour. No official cause of death has been announced. The local Medical Examiner's Office, however, told the Associated Press last week that the suspected cause of death is a drug overdose. He was 21.

A new report from TMZ Monday, citing the police report, claims that someone on Peep's management team interacted with him on his tour bus earlier that Wednesday and he "appeared to be fine." This management member added that Peep took a nap around 5:45 p.m., and when she checked on him shortly after he was "snoring and breathing without issue." Another member of Peep's management team checked on him later that evening and found him unresponsive, at which point CPR was administered and the authorities were called.

Peep's brother, Karl Åhr, who goes by Oskar, pushed back against many of the rumors surrounding the death in an interview with People Friday. As many have speculated, Oskar said the family has been told that Peep had been given laced pills. "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 said. "He thought he could take what he did, but he had been given something and he didn't realize what it was."

Oskar added that the death "really was an accident," and—despite Peep's public persona—he was happy. "My brother didn't take five Xanax pills every day, but he would take them and then post on Instagram about it," Oskar said. "I wish it would have paid for him to be a little safer, but the world needed him to have superlative problems that he dealt with in superlative ways. [Gustav Åhr] dealt with these problems much better than Lil Peep did, but people didn't know Gus, and there's a reason Gus doesn't sell."

Though several of the publications now ravenously reporting on his death ignored it, Peep's music struck a chord with thousands of listeners walking the line between rap's new wave and the raw melodies of early '00s pop punk and emo. In addition to his debut album Come Over When You're Sober Pt. 1, Peep will be remembered for the genre-hopping immediacy of his breakthrough mixtapes Hellboy and Crybaby.
