A former PTA treasurer stole over $20,000 from the South Fayette PTA from 2014 through 2016, a detective with the Allegheny County District Attorney’s Office alleged in a criminal complaint filed Thursday.

Ktistin Mandrick, 47, of Oakdale, is charged with one count each of forgery and theft by unlawful taking. She surrendered Thursday morning to DA detectives at District Magistrate Maureen McGraw-Desmet’s office in Bridgeville, and was released on a $20,000 unsecured bond, a DA spokesman said.

The complaint alleges Mandrick made thousands of dollars in cash withdrawals and forged a PTA officer’s name on several checks. She also used PTA funds to pay some of her personal expenses.

Detectives started their investigation in September 2016 after the newly elected PTA president and a school district employee noticed questionable withdrawals from the PTA’s bank account.

Mandrick was PTA President until July 1, 2016, when Maureen Hiser assumed the post.  Ms. Hiser told detectives that Mandrick became treasurer because she “insisted” on doing so.

Mandrick was asked by new PTA officers to hand over financial records. Ms. Hiser said Mandrick, “would not provide statements requested,” and “was not forthcoming with information requested.” Ms Hiser also said, “that [Mandrick] would become defensive when questioned about the PTA accounts,” the complaint said.

Bank records show that from August 2015 to July 2016 Mandrick withdrew $7,200 in cash from the organization’s bank account. She also allegedly wrote herself more than $11,000 worth of checks from the checking account and forged another officer’s name on some of those checks

The complaint said Mandrick used the money to pay her utility bills, purchase food and pet supplies, as well as clothes.

According to the complaint, of the $20,133.24 that Mandrick allegedly stole from the organization only $414.20 was supported with receipts.

She faces an Oct. 15 preliminary hearing in Bridgeville.
