A former Carlsbad pharmacy technician allegedly stole 20,000 opioid tablets from where she worked.
The DOJ says 30-year-old Amber Otero appears before a federal judge tomorrow in Roswell.
The department, however, has not released the name of the pharmacy where she worked.
A federal attorney says the investigation into Otero began last month after the pharmacy reported losing oxycodone tablets.
That pharmacy identified Otero as a possible suspect.
Authorities arrested her on Friday.
A conviction could mean 20 years in federal prison.
