PHILADELPHIA (CBS) – A Franklin Township concrete business is out $2.2 million, embezzled, prosecutors say, by a longtime employee.

Gloucester County prosecutors say the thefts came to light last May. That’s when officials at GMAC Construction discovered tens of thousands of dollars in unauthorized credit card charges as well as checks written to a recycling company owned by husband of the now former office manager, 46-year-old Joanne Bittner-Lieze.

“The initial credit card charges were used apparently for a lot of household expenses not related to the employer. The rest of the money, that’s what is still under investigation.”, according to prosecutor’s office spokesman Bernard Weisenfeld

Bittner-Lieze, who surrendered to authorities on Friday, is charged with second degree theft.

“That can carry a state prison sentence of five to ten years,” added Weisenfeld.

The Deptford Township woman is out on $75,000 bail.
