In 1999, nine-year-old Valiree Jackson vanished on her way to school near Spokane, WA. Her father Brad Jackson reported the disappearance and the entire community started searching for her abductor. As police began the investigation, they wondered if her long-lost mother Rosanne Pleasant might be connected to the disappearance. Police used GPS tracking to follow the perpetrator's movements, which not only led them to Valiree's body, but also showed the twisted motive in the perpetrator's mind. The Secret Service finds a hidden fingerprint to help detectives seal the case.
