On February 3, 1990, a 14-year-old girl ran away from her mother's home and disappeared without a trace. Her mother hoped Pasadena, Texas police could find her before it was too late. Six months later, their worst fear was realized when a farmer discovered the young girl's remains in an Illinois barn. The FBI was called in to help. Agents tracked down a trucker who they believed was responsible for 50 more deaths. Investigators knew they had to stop this menace of the highways.
