A homeless woman facing 20 years in jail for illegally sending her son to a Norwalk, Conn., elementary school pleaded not guilty to larceny charges. Tanya McDowell, 33, was arraigned Wednesday in state Superior Court on charges of first-degree larceny and conspiracy, accused of costing Norwalk taxpayers more than $15,000 by allegedly using a fake address to enroll her son, A.J., in Brookside Elementary School while she and the boy were homeless, stamfordadvocate.com reported Wednesday. McDowell said she and her son, who was 5 years old at the time, were homeless and staying with a friend in Norwalk when she enrolled him in the school system, WTIC-TV, Hartford, Conn., reported. A prosecutor in the case, Suzanne Vieux, is the stepdaughter of Norwalk Mayor Richard Moccia, who has publicly condemned McDowell -- who has a criminal past. She was convicted 10 years ago of robbing a bank in Trumbull, Conn., and was arrested in November for possession of marijuana and crack cocaine with intent to sell. She has pleaded not guilty to those charges in a case that is still pending, stamfordadvocate.com said. Defense attorneys Darnell Crosland and Michael Thomas told Judge Bruce Hudock they sought to transfer the high-profile case out of Norwalk in hopes of finding a more impartial jury. Her next court date is May 11.
