PLANO, Texas (AP) A North Texas pharmacist has been indicted on charges of conspiracy to distribute large amounts of the painkiller oxycodone.

U.S. Attorney John Bales said in a statement Friday that 29-year-old John Christopher Esparza of Granbury, Texas was indicted by a federal grand jury earlier this month.

Esparza allegedly sold large quantities of oxycodone to an informant. An investigation showed that about $2.9 million of oxycodone was unaccounted for in the pharmacy's inventory records.

If convicted, Esparza faces up to 20 years in federal prison. A trial date has not been set.
