A private investigator hired by the family of Amy Bradley, who vanished during a family trip aboard a Royal Caribbean cruise ship back in March 1998, said that he has identified two people of interest in connection with her disappearance. The FBI is offering up to a $100,000 reward for any information leading to Bradley's location, as well as information "that leads to the identification, arrest, and conviction of the person(s) responsible for her disappearance," according to an agency alert.
