It is every parent's worst nightmare.

Eric and Marilyn Behrman's 19-year-old daughter, Jill Behrman, goes out for a bike ride at 9:30 in the morning and vanishes into thin air. Her disappearance would have been strange enough had it happened in New York City or Los Angeles, but Jill was riding her bike in Bloomington, Indiana, in an area favored by local bicycle clubs.

Her strange disappearance prompts one of the largest missing persons investigations in Indiana history.

The Bloomington Police Department, State Police and the FBI interviewed hundreds of suspects, examined thousands of pages of testimony and drained 15 million gallons of water from a local creek in their relentless search for the popular coed.

Three area residents with long rap sheets emerged as prime suspects. One of them broke down and offers a videotaped confession. She passed a lie detector test and eyewitnesses corroborated crucial parts of her testimony. Yet none of the three are ever indicted for the crime. Then, a shocking discovery reveals why.

This weekend, join FOX News as Greta Van Susteren travels to Bloomington, Indiana to examine the road where Jill's bike was found and the creek where her body was allegedly dumped.

You'll hear exclusive interviews with the three primary suspects and we are now able to reveal information previously not available to the public.
