LeRoy Drier, 45, was one of three men killed during an armed robbery at the Shamrock Tavern in Davenport, Iowa, on the night of January 20, 1972. The robbery was carried out by a group of six young men from Rock Island, Illinois; inside the tavern the situation turned violent and the bartender and two patrons, including Drier, were shot and killed. Among the victims were Clifford H. Mutum, 63, and bartender Harold E. George, 54.

Five of the six men were arrested. Sherman White, then 17 and serving as a lookout, was convicted on multiple counts including murder and sentenced to life without parole; his conviction was later overturned by the 8th U.S. Circuit Court of Appeals for withholding of exculpatory evidence, and he subsequently pleaded guilty to second-degree murder. The shooter and another accomplice received life sentences, while two other members pleaded guilty to second-degree murder and served about a decade each.
