Patrick Bradford was once a proud police officer. "There's no question I was exceptionally good at it," he says. "And it came naturally for me. And it was just like being right where you're supposed to be." But today, Bradford is in prison serving ... (more)80 years for murdering his girlfriend, Tammy Lohr. In August 1992, she was stabbed repeatedly in her back and neck, before her body was set afire. The crime rocked Evansville, Ind. Tammy, a 24-year-old civilian jailer, was attractive, energetic and popular. Bradford insists he had nothing to do with Tammy's murder. Susan Spencer reports on this tangled, tragic case.
