Air date: Oct 21, 1997

During a robbery at a community centre, two men are killed in the boiler room when they confront the thieves. During the collection of evidence, an investigator finds a piece of wood which is later identified as part of a rifle butt. The rifle is traced to the two thieves, but it will take a forensic biologist to determine which of the two was the gunman.
