On the evening of Sept. 28, 2000, former Indiana state trooper David Camm came home to find his 35-year-old wife Kim and his five-year-old daughter Jill murdered, both shot execution-style in the head; his seven-year old-son Brad died after being shot in the chest. Just three days later, Camm, 36, was arrested and charged with the murders. Camm has adamantly denied any involvement in the murders. Correspondent Richard Schlesinger has spent years investigating the case, one with bizarre evidence and many unusual twists that would lead to an ending that no one expected.
