Dark Woods (S05E11): In June 1973, a young girl was abducted from a state park on the Missouri River while camping with her family. Several months passed with no leads, then an FBI agent took a particular interest in the case. Using a new technique known as criminal profiling, he predicted that the kidnapper would contact the girl’s family on the one-year anniversary of her abduction. When this prediction came true, the FBI agent noted behavioral clues, hoping that they could lead him to the kidnapper.

Deadly Trail (S03E05): When police in a small Washington State community began looking into the disappearance of a 22-year-old woman, they had no way of knowing it would evolve into a nationwide hunt for a sexual sadist. Police knew the killer’s identity, but he was a master of disguise. The FBI was called on to help. Agents discovered that several unsuspecting women across the northwest had fallen prey to his charms. As the number of abductions escalated, a massive media campaign became the FBI’s best chance of flushing out the serial killer, and putting an end to his violent rampage.

Dead Run (S06E02): A man is found suffocated in his Pennsylvania home, his checkbook, credit cards and vehicle appear to have been stolen. Fingerprints from the victim identify a recent escapee from a minimum-security prison, as well as his girlfriend. Investigators flag the dead man’s credit cards, and are alerted when one is used in North Dakota. The FBI is called in and joins another task force already assembled because of a suspected kidnapping. Authorities track the stolen card users to several locations in western states, and eventually dangerously close to the Mexican border. A chase to stop the felons from getting across the border ensues, ending with the two killers in custody.
