The Merced Multi-Agency Gang Task Force said it arrested a former federal prison guard for weapons possession, drug sales and possession of stolen property.
Brett Mejia, 34, was arrested late at night June 11 in her Atwater home, the task force said in a news release.
Task force agents and Merced probation officers went to her home for a probation compliance check. During a search, officers found “a substantial amount” of methamphetamine, packaging material, a scale and a loaded .25 caliber handgun, the news release said.
Searchers also discovered “numerous” identity items that had been reported stolen to the Atwater Police Department, including checks and credit cards.
Atwater detectives were contacted and began working a parallel investigation, authorities said.
Before they booked Mejia, agents determined that she’s a validated Surena gang member and once was an employee at the U.S. Penitentiary Atwater, but had been fired.
She was booked into the Main Jail on charges of possession of methamphetamine for sale, possession of a controlled substance in conjunction with a firearm, possession of a firearm by a convicted felon, possession of ammunition by a convicted felon, possession of stolen property and a probation violation.
Mejia is being held without bail.
