Exhibit A: Secrets of Forensic Science

When a young man goes missing and his wallet is found near Algonquin Park, his sister and mother call it murder, but without evidence, the police must deem him a "missing person". From interviews with relatives, it looks like the young man wanted to get away - he was on parole, his marriage had broken up, and his father's suicide still haunted him. For three years, his sister searches for her brother in vain. Finally she gives up. But on the eve of his memorial service, police get a tip about his murder. It takes forensic anthropology, bloodstain analysis, tool mark analysis and tenacious police work to unearth the story about the murder and nail the killer.
