Federal prosecutors have filed charges in Los Angeles in connection with the death of rapper and hip-hop artist Mac Miller, who died of a drug overdose almost a year ago. NBC News reports that a federal criminal complaint against a Hollywood Hills man was unsealed Wednesday.

“The 42-page criminal complaint filed in the Central District of California alleges that Cameron James Pettit, 28, supplied Miller with counterfeit oxycodone pills containing fentanyl,” NBC News reports. “Miller had asked to be furnished with ‘percs,’ an abbreviation for percocet, a prescribed painkiller containing oxycodone.”

Miller was found at his Studio City home on Sept. 7, 2018. His death was determined to be accidental, but it was found that he died from an overdose of alcohol, cocaine and fentanyl.

“Investigators, who served search warrants at multiple locations, recovered a plastic bag containing pills allegedly supplied by a prostitute and a madam,” NBC News reports. “Two days earlier, Pettit delivered to Miller counterfeit oxycodone pills that contained fentanyl, cocaine and Xanax.”

The report cites a DEA statement saying authorities believe Miller died after snorting the bogus painkillers.

United States Attorney Nick Hanna is quoted saying: “We are aggressively targeting drug dealers responsible for trafficking illicit fentanyl, which has become the most deadly facet of the opioid epidemic. We are committed to slowing the number of overdose deaths and prosecuting those responsible for spreading this most dangerous opioid.”
