This is one of the weirdest true crime stories of all time. For years the town of Circleville Ohio was the traget of insane anonymous letters. As the years went by the letter writer uped his/her game to include arsenic and booby trapped signs. One man was sent to prison over this but it didn't stop the letters. The entire time Paul Freshour was in prison the letters continued and to this day no on knows for sure who was behind the Circleville Letters.
