A Brunswick man has pleaded guilty to defrauding two well-known Maine companies out of nearly half a million dollars. Matthew LaForge pleaded guilty to mail fraud and tax evasion Tuesday in U.S. District Court in Portland. Court records show that while employed at South Portland-based Wright Express from 2006-2008, the 38-year-old LaForge fraudulently billed and collected $231,000 from the company for marketing services supposedly provided by a company that he made up. Prosecutors say LaForge used the same scheme to defraud Freeport-based L.L. Bean out of $220,000 while working there as a financial analyst from 2009-2011. He faces up to 20 years on the two mail fraud charges and up to five years for tax evasion. A sentencing date has not been scheduled.
