A woman is found murdered at a truck stop in Nashville Tennessee. She is nude, displayed grotesquely, and a chunk of her flesh is missing. Was it to hide her identity, or did the killer take a trophy? In episode 86 of The First Degree, Jac, Alexis and Billy not only speak with the sister of the victim, but also with Detective Pat Postiglione, who was tasked with finding the killer-who soon learns that this wasn’t his first kill.
