Jerry Heller, the longtime music manager who helped launch the career of groups like N.W.A., has passed away.

Heller died after suffering from injuries due to a car accident he was involved in on Friday morning (Sept. 2, 2016). He was 75. The website reports that it’s unclear whether he died from a medical emergency which resulted in him slamming into a mini-van, or it it’s the crash that killed him.

His cousin, Gary Ballen, is the person who confirmed his passing to Billboard.

Heller is best known for co-founding Ruthless Records with Eazy-E. He was the manager of N.W.A for four years, but later had a falling out with the hip-hop group after both Dr. Dre and Ice Cube felt he was stealing from them. His partnership with Eazy-E, however, continued until the rapper’s death from AIDS in 1995.

Heller also made headlines late last year after he filed $110 million defamation lawsuit against the producers of Straight Outta Compton, including Dre and Ice Cube, because he was upset that they portrayed him so negatively in the film.
