One day when Adam was at the still alone, he was approached by Mitchell, who asked to buy a gallon of liquor. Mitchell was in fact a revenue officer. After Adam had sold him the liquor, Mitchell revealed his identity. Adam grabbed one of the rifles that the brothers kept handy in case of trouble with the law, and shot and wounded Mitchell.
