A bookkeeper has been charged with stealing about $320,000 from her employer through fraudulent credit card purchases, money transfers and salary increases.

Federal prosecutors allege that Marie Greany of Mattapoisett embezzled the money from two unidentified Middleboro companies from about January 2006 until September 2012.

According to court documents, Greany worked for the companies at various times as a bookkeeper. The companies specialize in computer design and consulting.

Greany was charged Monday, March 17 in U.S. District Court under a federal wire fraud statute.

Prosecutors say Greany transferred bank funds from the companies to pay her American Express credit card bill and that, through the company’s payroll, she issued herself expense reimbursements as well as “increased salary payments to which she was not entitled.”

Additionally, Greany allegedly used the company-issued credit card for unauthorized personal expenses. In the court report those purchases are listed as, “travel, tickets to various sporting events and theater productions, restaurant meals, and tuition, as well as the costs for operating her photography business.”

She is also accused of writing two checks from the company's bank account.

Greany’s next U.S. District Court date is scheduled for March 26. Greany’s attorney Anthony Fuller could not be reached for comment.
