Touch of Evil - S14.E8

In the 1990s, a dismembered body is dumped on the side of the New Jersey Turnpike and before police realize it, bodies are turning up between two states. The killer's methods involved dismembering the bodies and wrapping the parts in plastic bags, which were carefully washed to remove all incriminating evidence. The killer eluded capture for almost ten years and then new technology revealed fingerprints no one knew were there.
