The town of Barre’s former tax collector has pleaded not guilty to charges that she stole more than $300,000 of the town’s money. Marcia Langelier, 61, was arraigned Thursday in Worcester Superior Court on charges of larceny over $250 by a common scheme; embezzlement by a city, town, or county officer; and making false entries in corporate books. The Worcester Telegram & Gazette reported that prosecutor John O’Leary said in court that Langelier had more than $350,000 in gambling debts. Prosecutors allege that the thefts occurred from 2005 to 2011. A judge released her on $2,500 bail and ordered her not to leave the state or gamble.
