MARIETTA — A woman who works in the adult drug court within Cobb Superior Court was arrested Friday afternoon on charges of skimming an unknown amount of cash from the office.

Tomasita Reavis, 55, of Marietta, had been a full-time employee in the drug court office for four years, after transferring there from the Cobb Sheriff’s Office, where she had worked since 2002.

She earned $17.03 per hour in drug court before she was fired Friday afternoon.

Cobb Police Sgt. Dana Pierce said Reavis is charged with felony theft by taking. Because she is a government employee with a fiduciary responsibility, the theft is automatically a felony, regardless of amount, he said.

It’s not yet known how long the alleged thefts have been occurring.

Court Administrator Tom Charron said other drug-court employees alerted him that something wasn’t right, and he asked the Cobb-Marietta-Smyrna task force to investigate.

Offenders come to the drug-court office, which is in the basement of the old Superior Court building on Waddell Street, to have drug and alcohol tests done on-site. The urine tests vary in cost, but the average is $25, and receipts are written.

The thefts were done purely by taking cash, Charron said, and the court will also now conduct an audit.

“I can’t even tell you the amounts, it’s so preliminary right now,” Charron said Friday afternoon. “I want to emphasize that no member of the public was denied a service. They paid, they got the service. All samples were accounted for.”

The cash collected is supposed to be turned over to Superior Court Clerk Jay C. Stephenson’s office daily.

Although Charron said there is no indication any other employee was involved in the thefts, he acknowledged that proper accounting oversight was not done. Reavis was one of five employees in the drug court, reporting to director Christy Garrett.

“The procedures are there, they just have not been adhered to,” Charron said. “We’ll be reviewing procedures to tighten up where we need to. … I feel good that our people came to me, and we were able to go to the police.”

Recently retired Superior Court Judge George Kreeger oversees the adult drug court, and now as a senior judge will continue to do so, Charron said.

Kreeger was unaware of the thefts, and the situation had “nothing at all” to do with his Sept. 28 retirement, Charron said.
