Dr. O.C. Smith, a popular medical examiner in Memphis, Tenn., was apparently attacked on June 1, 2002, as he was leaving work. He was found wrapped head-to-toe in barbed wire with a bomb strapped to his neck. Dr. Smith survived, but he lives in fear that his assailant is waiting to attack again. Who wants to harm the city's medical examiner? Correspondent Troy Roberts reports.
