Mac Miller Dead of Suspected Overdose at 26

Mac Miller died on Friday of a suspected drug overdose, PEOPLE confirms. He was 26.

The rap star was found unresponsive at his home in San Fernando Valley, California, around noon on Friday after a call was made for an “immediate dispatch” for a patient in cardiac arrest, according to a 911 call obtained by The Blast. A source tells PEOPLE Miller was pronounced dead at the scene upon arrival of authorities.

TMZ was first to report the news.

The Los Angeles Coroner’s Office, as well as a rep for Miller, did not immediately respond to PEOPLE’s request for comment.

The “My Favorite Part” rapper, was born in Pittsburgh and first launched into the public eye in 2010, when he released his fourth mixtape K.I.D.S when he was 18, which contained hits “Nikes on My Feet” and “Best Day Ever.” The following year, his first studio album Blue Side Park debuted at No. 1 on the Billboard Hot 200.

Miller, who had struggled with drugs throughout his life, and his girlfriend of two years, Ariana Grande, broke up earlier this year.

Hours before his death, Miller posted a series of videos on his Instagram that were taken at a recording studio.

The rapper’s latest album, Swimming, was released on Aug. 3 and he was scheduled to begin touring in October.

Less than a week after news broke that Miller and Grande had split, on May 14, Miller was arrested for drunk driving.

Early that morning, the rapper was arrested for DUI and hit and run after he struck a power pole in the San Fernando Valley with his Mercedes-Benz G-Wagon and fled the scene; after law enforcement officers matched the vehicle’s license plates to Miller’s address, they arrested him at his home, a Los Angeles Police Department public information officer previously told PEOPLE.

The rapper went on to open up about his arrest during a conversation with Zane Lowe on Beats 1 on Apple Music in July.

I made a stupid mistake. I’m a human being,” Miller explained. “But it was the best thing that could have happened. Best thing that could have happened. I needed that. I needed to run into that light pole and literally have the whole thing stop.”

However, Miller went on to let all of his fans know that they shouldn’t worry about him, because he’s doing fine.

“I have people that care about me and fans that love my music and it’s a beautiful relationship with them — people who have been with me through being a 19-year-old wide-eyed kid to being a self-destructive depressed drug user to making love music to all these different stages. Then they see something like that and they worry,” he explained. “So your first reaction is, ‘Let me tell them I’m cool.’ ”

During the interview, Miller also explained that both he and Grande had moved on since their split — and that he wished her well.

“I was in love with somebody. We were together for two years. We worked through good times, bad times, stress and everything else. And then it came to an end and we both moved on. And it’s that simple,” he said.

“It’s all positive energy,” he added. “I am happy for her and [the fact that she’s] moving forward with her life, just as I’m sure she is with me.”

Grande, 25, and Miller first went public with their relationship in September 2016 — three years after they collaborated on her hit single “The Way.”

Shortly after their breakup in May, Grande began dating Pete Davidson, to whom she became engaged to in June.

Following Miller’s DUI arrest, Grande also responded to a tweet blaming her for what happened.

“I am not a babysitter or a mother and no woman should feel that they need to be,” she wrote. “I have cared for him and tried to support his sobriety & prayed for his balance for years (and always will of course) but shaming / blaming women for a man’s inability to keep his s— together is a very major problem.”

While opening up about his drug use in 2013, Miller told Complex that “things got out of hand” during his Macadelic Tour in 2012.

“I was not happy and I was on lean very heavy,” he remarked. “I was so f—ed up all the time it was bad. My friends couldn’t even look at me the same. I was lost.”

Two years after getting sober in 2015, Miller told W Magazine that after having “spent a good time very sober…now I’m just, like, living regularly.”

“I don’t believe in absolute anything, but I think not sharing that type of information, because it becomes like, ‘Oh he’s sober, oh he’s not, oh he has a beer, oh my God.’ I just realized some things are important to just keep for yourself,” he added.
