Tina Louise Leone’s body was dumped near Interstate 95 like a sack of trash. Laura Burgess was strangled and stabbed with a shard of glass in a D.C. hotel. Dusty Shuck was found with her throat slashed outside a Frederick, Md., truck stop.

The women are among hundreds who federal law enforcement officials believe have been slain by truck driver serial killers, motorized predators who can pick up their victim in one state, kill her in another and be across country before the body is ever found.
