The leader of the so-called “Oxy Bandits” crew has been convicted of organizing armed robberies of oxycodone at 15 independently owned pharmacies across Southern California, federal prosecutors said Wednesday.

A judge found Tyrome Lewis, 26, guilty of eight felony charges including robbery, conspiracy and possession with intent to distribute oxycodone, the U.S. Attorney’s Office said in a statement.

Lewis, who’s been in custody since his arrest in July 2019, conspired with others to target “mom and pop” pharmacies in Los Angeles, Orange and Riverside counties, prosecutors said.

“He also assigned the roles from the crew members, and then he served as a lookout while co-conspirators committed the robberies. Following the pharmacy robberies, Lewis and others would sell the stolen prescription medication on the black market,” the statement said.

Lewis faces life in prison when he’s sentenced September 23.

The case is part of a broader investigation of armed pharmacy robberies begun in 2019 by the FBI and the Los Angeles County Sheriff’s Department. The U.S. Attorney’s Office said it has so far charged 21 individuals, with 19 convictions. Two defendants are awaiting trial.
