F2: Forensic Factor - Season 1 (2003)

How do bugs, pigs and even the weather help investigators solve crimes? From tropical Hawaii to the frigid waters of Lake Ontario, forensic experts reveal, in gory detail, the clues nature leaves behind on a human corpse.

Serial killers are often twisted geniuses; so cunning that catching them seems almost impossible. But from Jack The Ripper to those who terrify us today, their bizarre behavior is as specific as a signature. Sophisticated crime fighters map the psychological and physical terrain of multiple murderers.

From the tips of their ears to the soles of their feet - criminals are betrayed by the clues their own bodies leave behind. A killer's ear against a wall, his hand on a door, the path that he walks - even the slightest impressions left at the scene help crime fighters find their man.
