Questions Surround FBI Agent's Disappearance

The case of a former FBI agent who disappeared from an Iranian resort island nearly five years ago has come back into the headlines. His family has decided to tell the media, for the first time, about some developments in the case that occurred last year — including a video of the former agent, Robert Levinson, who is shown asking the government to work for his release. NPR's Dina Temple-Raston talks to Lynn Neary about the questions surrounding the case and the family's efforts to bring Levinson home.
