33 - 14: My Brother's Bomber (1)

When filmmaker Ken Dornstein was 19 years old, his older brother David was one of 189 Americans killed in the bombing of Pan Am Flight 103 over Lockerbie, Scotland. In this three-part series, Dornstein embarks on a quest for answers -- diving deep into the case files, assembling a list of suspected plotters, and tracking them for almost five years across the Middle East and Europe.
