In the last month there have been eight robberies of gas stations and all-night markets. The police have been unable to get a positive id from a line up. The only thing to do is stake out as many all-night markets and gas stations as they can. During a stake out a grocery store is held up and the manager's son, Jack Bishop, is shot. His girlfriend Miss Wilson was scared but she got a good view of them and is able to give a good description to the police.
