30-Year Hunt: Killer Holds Secret to Girl's Grave

For three decades, investigators have pursued a single, grim goal: to find 12-year-old Sara Anne Wood. They are locked in a unique and prolonged negotiation with her convicted killer. He is a known serial predator in prison for Sara's 1993 abduction. Authorities believe he alone knows where he hid her body. Their strategy is a relentless psychological game. They aim to extract the location from him, offering small incentives while withholding the possibility of parole. Every interaction is calculated to leverage his desires against the family's need for closure. As reported by "48 Hours" correspondent Erin Moriarty, this standoff continues. It is a decades-long effort to bring Sara home and finally answer her family's enduring question.
