The Forensic Killer

San Francisco wakes to the news of another brutal killing. The Criminal Investigation Team are baffled by the lack of evidence at this latest crime scene. Just like any other it's the same - no DNA, no evidence, no trace, nothing to implicate a potential suspect.

Victor Corelli heads up the team and has just signed up Tom Johnson as the newest recruit. Young and enthusiastic, Tom has always wanted to be a real hero.

As the lack of evidence brings them no suspects and the bodies begin to pile up, the team are under pressure to find their guy and begin to look a little closer to home. What does it take to catch a killer? As they say it takes one to know one.
