On June 2, 1953, a court-martial hearing began at Taegu Air Base, South Korea. The defendant, Air Force Staff Sgt. Giuseppe Cascio, pictured in a 1952 mug shot, was accused of attempting to conspire and sell military secrets to the enemy. This was the first known case of an American to be accused of committing espionage during the Korean War. (U.S. Air Force photo)
