COLD CASE FILES: Episode 58

Sometimes police co-operation is a necessary tool in the fight against crime. In this show we see how it takes three police departments in upstate New York to finally home in on a serial murderer and rapist.

It is not until they put their extensive forensic evidence together that the killer can be put to justice.

Forensic evidence can often help solve cases many years after a crime is committed. We see this in the case of a man who is convicted by forensic evidence 22 years after killing a young mother.
