David William Cooper, 58, of Omaha, Nebraska, was found dead on September 10, 2015. A Council Bluffs, Iowa native, Cooper was described as well regarded in his community and is survived by a large family including his daughter Shamanesha Edwards and several grandchildren.

His death remains unsolved. Investigators and local crime stoppers have pursued leads over the years but say they have not developed enough evidence to make an arrest. The killing occurred during a period of elevated violent crime in Omaha, and Cooper’s case is listed among several cold cases the city continues to review; rewards have been offered for information that could help.

Anyone who knew Cooper or who has information about his death is asked to contact the Omaha Police Department or local tip lines.
