From May to June Omaha Police went to the homes of at least 36 to 40 Black men, between the ages of 20 and 40, and asked for DNA samples via mouth swabs. Police said the DNA tests were needed to aid in the investigation of four rapes over the last two years. The perpetrator was described in over broad terms as "black, 25 to 40 years old, 5-foot-3 to 5-foot-9 inches tall, stocky with a large stomach and weighing 175 to 250 pounds. This "dragnet sweep" of Black men enraged the African American community. Some of the men, such as defense attorney Bill Gallup's client, who asked to remain anonymous, involuntarily provided DNA. Gallup's client said he gave a DNA sample even after he'd been exonerated of the rapes because police handcuffed him and forced him to. Apparently most of the men targeted for the DNA worked at the Omaha Public Power Company.
