LEWISTON, Maine (AP) -The 13-year-old Lewiston boy charged with starting a massive apartment fire has been ruled not competent to stand trial at this time. The arson case against him has been suspended by a judge who determined prosecutors have not met their burden of proving the boy is competent to stand trial. The boy faces four counts of arson stemming from fires that burned four apartment buildings and a garage on Bartlett and Pierce streets on May 3. No one was hurt. The blaze was one of three arsons at about the same time that terrorized the city. Others have been charged in connection with the other fires. The judge says that while he is not competent now, he may be in the future.
