Forensic Files

Watchful Eye (13x45)

Air date: Apr 30, 2010

A state park employee is murdered in the park office in the middle of the afternoon. There’s a wealth of evidence at the scene, but it doesn’t implicate the prime suspect, it clears him. Six years -- and 600 leads -- later, advances in DNA technology enable investigators to identify and convict the killer. Originally aired as Season 13, Episode 44.
