John Duprey’s house at 6066 Buckingham Avenue was bombed on April 7, 1972. Duprey worked for the Nebraska State Liquor Commission as a liquor inspector, and his home was supposedly bombed because of that. According to the ATF, the bomber used dynamite with a 4″ fuse. The bomb also caused significant damage to the home of David Burrell at 6070 Buckingham Avenue. August 1972, federal agents with a search warrant raided the home of Hells Angels member Roger Levell in East Omaha, ostensibly on suspicion of his connection to the explosion. While weapons and drugs were found, no related explosives were reported.
