Robert L. Bob Hanna, 51, was working the night shift at a Kwik Shop in Lincoln, Nebraska, on July 7, 2016, when a robbery turned fatal. Surveillance footage shows a man enter the store at 14th Street and Adams Street, loiter briefly, then approach the counter with a handgun and demand money. A single shot struck Hanna in the chest; he was taken to a hospital and later died of his injuries.

Police released stills and video from the store cameras and described the suspect as a male of unknown race, wearing a dark hooded sweatshirt with a distinctive emblem on the front, light-colored pants and dark shoes. No arrests have been announced and the case is now listed as a cold case while the homicide investigation remains open.

If anyone remembers seeing someone in that sweatshirt near 14th and Adams around that time or has information about the robbery, please share what is known with Lincoln police.
