The theory was soon debunked, however. An expert who defused one of the unexploded bombs approached the Bureau of Alcohol, Tobacco, Firearms and Explosives, claiming that he recognized the bomb’s unique design. Specifically, it featured four rods with welded ends that enhanced the bomb’s explosive potential. The expert had seen this once before, 17 years earlier.
In 1972 a softly-spoken man from Georgia, Walter Leroy Moody Jr., had injured his first wife, Hazel, with a very similar homemade device that had detonated inside his house. But Hazel had not been the target of the bomb. Instead, Moody had intended to send it to a car dealer responsible for repossessing his vehicle.
