The former bookkeeper at a Claiborne County elementary school is accused of stealing more than $6,600 from the school, according to the state Office of the Comptroller.

A Claiborne County grand jury indicted Teresa Poston on one count of theft of property over $2,500.

Poston kept the books at Powell Valley Elementary School. She is alleged to have stolen "at least" $6,694 from the school over two years.

According to the Comptroller's Office, which investigated, she used several schemes to get the money.

"These included failing to record and deposit cash that was collected by the school’s cheerleading and dance teams, failing to deposit money from a school wide fundraiser, and substituting unrecorded checks for cash collections and keeping the cash for her own benefit," according to the Comptroller's Office.

A review showed she created collection records from athletic events and put teachers’ signatures on them.

"Poston counted, receipted and deposited these funds without anyone else verifying their accuracy," the Comptroller's Office alleges.

She took the money for personal use, according to the comptroller. Poston quit in January, according to the comptroller.

Authorities think more money may have been taken.

Comptroller Justin Wilson said in a statement the case illustrates why it's so important for more than one person to be involved in handling money for a business or organization.
