72 Hours: True Crime

Three bodies are found in a house, arms tied behind their backs. Stab wounds to the neck. Bloody footprints in the upstairs hall. These are the clues to a killing spree that leaves a young woman, her boyfriend and an elderly church deacon dead. When evidence and fellow church congregants suggest a mentally disturbed youth from their bible class could be the culprit, police believe they have their man. But the police are wrong. And a frenzied killer is still on the loose.
