The man federal authorities believe sold Mac Miller lethal counterfeit drugs could be facing a lengthy prison sentence.

On Wednesday afternoon (Sept. 4), a press release from the U.S. Drug Enforcement Administration reported that 23-year-old Cameron James Pettit could face a maximum of 20 years in federal prison if he's convicted for one count of distribution of a controlled substance, which is a charge he was hit with after he was arrested yesterday.

Authorities allege that Pettit sold Miller 30-milligram oxycodone pills, cocaine and Xanax, but ended up selling the rapper counterfeit oxycodone pills mixed with fentanyl. The pills were allegedly sold to Miller on Sept. 5, 2018, which was just two days before his death on Sept. 7, 2018. A November 2018 toxicology report indicated that Miller's cause of death was an accidental overdose of fentanyl, cocaine and alcohol.

After the rapper overdosed, Pettit's friends sent him direct messages on Instagram about Miller's death. According to court documents, Pettit quickly voiced his concern about the situation.

The court docs allege that when asked how he was doing, Pettit said, "I am not great ... Most likely I will die in jail." He also reportedly told friends that he thought it was best for him to avoid social media after news of Miller's death spread.

Feds say another narcotics dealer had also supplied Miller with drugs before the rapper died, but their drugs did not contain any fentanyl, which the DEA says is up to 50 times stronger than heroin.

“While the death of any victim of the opioid epidemic is tragic, today’s arrest is another success for the DEA’s HIDTA Fusion Task Force,” said DEA Los Angeles Deputy Special Agent in Charge Daniel C. Comeaux. “Let our message be clear, if you peddle illegal drugs and kill someone, the DEA will be the voice of the victim. We will not rest until you face the justice system.”

The one-year anniversary of Mac Miller's tragic death is this Saturday.
