A St. Joseph man has been found guilty of reckless conduct, after a weapon was accidentally discharged at a Bloomington gun show last year. Robert Rigdon is a pawn shop dealer in Urbana. He reportedly failed to make sure guns he took to the show were unloaded. The gun went off while a man was holding it and struck three others. Rigdon could receive up to a year behind bars, probation or fines of over two thousand dollars.
