A man has been charged with selling counterfeit opioid pills to Mac Miller two days before the rapper died of an overdose.

The Drug Enforcement Agency says in a statement that 23-year-old Cameron James Pettit of Los Angeles was arrested Wednesday and is expected to appear in court later in the day.

A DEA affidavit alleges that Miller asked Pettit for oxycodone and other drugs, but on Sept. 5 Pettit gave Miller counterfeit oxycodone pills laced with the powerful opioid fentanyl.

An autopsy found that the 26-year-old Miller died in his Los Angeles home on Sept. 7 from a combination of fentanyl, cocaine and alcohol.
