Grammy Award-winning rapper Coolio has died of a fentanyl overdose, the artist’s manager said on Thursday, six months after the 59-year-old singer was found dead at a friend’s home in Los Angeles, Reuters and Agerpres reported.

Coolio, real name Artis Leon Ivy Jr., is best known for his 1995 hit “Gangsta’s Paradise,” which appeared on the album of the same name.

The song, which was part of the soundtrack to the film Dangerous Minds, was awarded the Grammy Award for Best Rap Solo Performance the following year.

Coolio’s manager, Jarez Posey, said the Los Angeles County Medical Examiner’s Office notified the rapper’s family Thursday that the musician died of a fentanyl overdose.

The medical examiner’s office did not immediately respond to a Reuters request for details.

The highly addictive substance is 50 times stronger than heroin, making it the most dangerous drug threat facing the United States. Only two milligrams are required for a fatal dose.

Federal agents in the United States say they have seized enough fentanyl to kill every American in 2022.

Most fentanyl enters the US from Mexico, where the substance is manufactured in secret factories run by the Sinaloa and Jalisco cartels, which are also responsible for Mexico’s horrific crime.

Documentary about Coolio

The rapper’s children intend to pay tribute to their father with an upcoming documentary, as well as other film projects, Jarez Posey said.

Born in Pennsylvania in 1963, Coolio began establishing himself in the West Coast hip-hop scene after moving to Compton, California.

He made his debut in 1994 with the album “It Takes a Thief”, and shortly after that the single “Lakeside” entered the top ten.
