a 'deputy' sheriff
(..) Tom Robinson's dead. They were taking him to Abbottsville... for safekeeping. Tom broke loose and ran. The deputy... called out to him to stop... and Tom didn't stop. He shot at him to wound him... and missed his aim. Killed him. The deputy says... Tom just ran like a crazy man. The last thing I told him was not to lose heart... that we'd ask for an appeal. We had such a good chance. (..)1962 To Kill a Mockingbird
