A former postal worker pleaded guilty in federal court in Boston Tuesday to stealing more than 200 video games from mail he handled, US Attorney Carmen M. Ortiz’s office said. James L. White, 68, of Dorchester stole the games between July and November 2012 from parcels at the US Postal Service’s General Mail Facility in Boston. He resold the items to a software and video game retailer, Ortiz’s office said in a statement. White’s sentencing for mail theft is slated for May 8. He faces up to five years in prison and a maximum fine of $250,000, Ortiz’s office said.
