A farmer's wife from Ohio took her three children on a vacation to Florida and wound up in the wrong place at the wrong time.

A brutal and sadistic murderer lured them onto his boat with the pretense of a sunset cruise of Tampa Bay.

But when they got far away from the shore, he raped and murdered them and threw their weighted-down bodies overboard.

The three-year search for their killer would involve multiple law enforcement agencies, the media, the FBI, and a computer named HOLMES.

If not for a brochure found in the women's car, a dedicated team of investigators, and a suspicious neighbour, this depraved killer might never have been caught.
