CHARLOTTE. (AP) — Federal prosecutors say a Gastonia woman has been sentenced to more than three years in prison for stealing nearly $600,000 from a Charlotte company that builds and repairs tennis courts and running tracks.

The U.S. Department of Justice announced Monday that 40-year-old Jennifer Ann Champagne was also ordered by a judge to serve a year of supervised released and to pay restitution of $594,208.01. Champagne pleaded guilty in July to making and possessing forged and counterfeit securities, wire fraud and access device fraud.

Champagne was an office manager and bookkeeper who prosecutors say signed the company president’s name on forged checks, then altered the books and records to hide the theft.

Court records also show Champagne used the company’s credit card to make more than 400 unauthorized charges exceeding $40,000.
