Paul and Billy look into two separate cases nearly four decades apart, each haunted with a voice of the offender. The first case, from Canada, is searching for a murderer. A man picked up Amber Tuccaro as she hitchhiked her way into town. He didn’t know his voice was being recorded as she protested. The other is a kidnapping—the apparent abductor of Margaret Ellen Fox calling her parents. Billy and Paul are hoping that the Murder Squad may recognize these evil voices, and help deliver justice.
