The cause of A$AP Yams’ untimely passing has been revealed.

Back in January, 26-year-old A$AP Yams passed away in tragic and mysterious circumstances. At the time, the cause of his death was unknown but many close to the A$AP Mob co-founder denied that drugs were involved.

New York City’s Chief Medical Examiner has now determined that Yams’ death was “an accident caused by acute mixed drug intoxication (inc. opiates & benzodiazepine), as the New York Times reports.

Yams, born Steven Rodriguez, co-founded New York’sA$AP Mob collective in 2007 with A$AP Bari and A$AP Illz. The crew would link up with A$AP Rocky and A$AP Ferg soon after; Rocky’s 2011 breakouts ‘Peso’ and ‘Purple Swag’ made the group a household name for rap fans.

Rodriguez remained a key behind-the-scene figure, a budding rap mogul often compared to Diddy, Damon Dash and Irv Gotti. In 2013, he told the New York Times, “We wanted to become big, but we didn’t want to do it by hopping on somebody else’s wave. We wanted to come in the game with our own wave.”
