LOS ANGELES — Even by today’s get-famous-quick standards, Pop Smoke became hot at microwave speed.

He released his first album, “Meet the Woo,” last July, and in the months to follow, he collaborated with Nicki Minaj, Travis Scott and others. His second album opened this month at No. 7 on the Billboard 200 chart.

He had moved on from his family’s duplex in a middle-class section of Brooklyn, and, at 20 years old, was living in a rented four-bedroom home owned by one of the “Real Housewives of Beverly Hills,” with a backyard pool featuring expansive views of the Hollywood Hills.

Before dawn on Wednesday, several people broke into that home, at least one holding a gun and at least one masked, according to the Los Angeles police. Someone staying there contacted a friend on the East Coast, who then called 911. Within minutes, the call was relayed to Los Angeles and the police were at the home, but it was too late; the intruders had fled and a person inside had been fatally shot. Pop Smoke’s record label, Republic, confirmed that he was the victim.

There were no arrests Wednesday, and the police said they were still investigating a motive.

A number of celebrities in Los Angeles have been victims of home invasions in recent years, and fans of Pop Smoke, whose real name was Bashar Jackson, wondered whether he had unwittingly provided bait to thieves by posting photos of cash, and his address, on social media.
