Three men have been charged with providing the drugs that led to Mac Miller's overdose on September 7, 2018, the BBC reports.

Cameron Pettit, Stephen Walter and Ryan Reavis were indicted by a Los Angeles Grand Jury on federal drug distribution charges. They are accused of conspiring and distributing cocaine and oxycodone pills laced with fentanyl that led to Miller's overdose.

According to court documents as reported by Reuters, Miller asked Pettit for Xanax, cocaine and 10 “blues” (oxycodone) on September 4, 2018. But prosecutors say that Pettit provided Miller counterfeit pills containing fentanyl, an opioid 50 times more potent than heroin.

“It has become increasingly common for us to see drug dealers peddling counterfeit pharmaceuticals made with fentanyl. As a consequence, fentanyl is now the No. 1 cause of overdose deaths in the United States,” U.S. Attorney Nick Hanna said when announcing the indictment. "These defendants allegedly continued to sell narcotics after Mr. McCormick’s death with full knowledge of the risks their products posed to human life."

Pettit, Walter, and Reavis were previously arrested in connection with the rapper's death. If convicted, they face up to life in jail.
