Rapper Lil Peep, an emerging voice on the hip hop scene and a YouTube star, has died at the age of 21, police and a business associate confirmed to CNN Thursday.
A spokesman for the Tucson, Arizona, Police Department told CNN that police were called just before 9 p.m. (11 p.m. ET) Wednesday night after Lil Peep was found unresponsive by his manager in his tour bus and said that first responders "rendered medical aid but they were unable to save him."
"After speaking with people on scene and going into the tour bus, (police) said that there was evidence of a possible drug overdose, most likely from Xanax," Sgt. Pete Dugan told CNN in a phone interview Thursday.
"Obviously, we're not medical examiners, so there will be an autopsy to determine the exact cause of death," Dugan said, adding that there was "no sign of any kind of foul play" and police are "treating it as a suspicious death case, most likely from an overdose."
Many fans first discovered him via the streaming service Soundcloud, where he was one of its biggest stars.
In June, the New York Times described the rapper in an article as having "evolved into something like the scene's Kurt Cobain, with several astonishingly gloomy and diabolically melodic releases, and a body that is in constant flux: hair dyed one color after another, an anarchy sign and the word 'crybaby' tattooed on his face."
"His songs find a middle ground between hip-hop bluster and emo's bulked-up anxiety, a blend that feels eminently of the moment, and inevitable," the article stated.
His debut album, "Come Over When You're Sober (Part One)," dropped on September 1 and found Pitchfork dubbing him an "emo rap alchemist.
"Peep's philosophies are no more profound than a great Instagram caption, and he can come off as a bit of an indignant kid, but it's easy to see why a new class of spitfires are using him as a talisman for their anxieties," Sheldon Pearce wrote for Pitchfork.
