A 44-year-old nurse who worked in the Putnam County jail for a private company is behind bars on multiple charges after antibiotics and other medication were taken out of the jail, according to the Sheriff’s Office.

Tina Sue Anderson of County Road 21 in Hawthorne is in custody on 10 counts of possession of a medication without a prescription, five more of theft and one each of practicing medicine without a license and distributing amphetamines, according to the Sheriff’s Office. Her bail is $137,500.

Anderson was employed by MTC Medical, contracted to provide medical care for Putnam inmates. When an inmate’s treatment is done, MTC Medical’s doctors and nurses are supposed to return unused medication to the pharmacy, the Sheriff’s Office said.

When deputies discovered unusual activity surrounding disposal of medication left over when inmates were released about three weeks ago, detectives began an investigation. They learned antibiotics and other medication were being stolen from the jail and MTC Medical after inmate releases, the Sheriff’s Office said. The investigation also revealed that Anderson had a legal prescription for her own narcotic medication, but some had been sold at least once to a family member.

Anderson was arrested Wednesday and is now in the St. Johns County jail since she worked with inmates in Putnam’s facility, according to the Sheriff’s Office.
