“On Jan. 29, 2013, a volatile man with a grudge against the government kidnapped a 5-year-old boy from a school bus in Midland City, Ala., and held him by force in an underground bunker. It was one of the most difficult and dangerous hostage cases ever handled by the Federal Bureau of Investigation.” The always interesting Michael M. Phillips takes you inside the case by way of stories, documents and audio recordings: A Stolen Boy, an Angry Loner, an Underground Bunker.
