A Fairfax County woman was indicted by a federal grand jury last week on charges of embezzling nearly half a million dollars from a Sterling-based landscape and construction company, authorities said Monday.

LeeAnn Dove, 48, of Herndon was indicted in U.S. District Court in Alexandria on 15 felony charges, including wire, mail and bank fraud, prosecutors said.

According to the indictment, Dove allegedly used her position at Great Falls Landscapes to add to the company’s payroll fake employees whose paychecks she then deposited into her personal account.

Dove is also accused of using company credit cards for personal purchases, including electronics, furniture, limousine services, concert tickets and thousands of dollars in gift cards, according to court records. Prosecutors say she embezzled nearly $490,000 during a six-year scheme from 2004 to 2010.

The indictment resulted from an investigation by the U.S. Secret Service and the Loudoun County Sheriff’s Office as part of the Washington Metropolitan Area Fraud Task Force, the Loudoun Sheriff’s Office said.

If convicted, Dove could face up to 20 years in prison for each wire and mail fraud count, and up to 30 years for each bank fraud count, authorities said.
