Barnett Adams, 33, was shot and killed outside a convenience store on the 5600 block of West Chicago Avenue at Chicago Avenue and Central Avenue in the Austin neighborhood on the evening of December 19, 2013. Witnesses inside the store saw a heated argument between Adams and another man that moved onto the sidewalk; the pair traded punches, and after Adams knocked the other man to the ground that man drew a handgun and fired multiple times, striking Adams in the neck and shoulder. Bystanders carried Adams back into the store, first responders took him to Mount Sinai Hospital, and he was pronounced dead about an hour later.

Detectives developed leads after canvassing the area and through a narcotics buy-bust operation; Chicago Police arrested James Wilson, 30, of Forest Park, in Urbana and charged him with first-degree murder. At trial eyewitnesses, including the store manager, said Wilson was felled by a single punch, then opened fire; one witness said the shooter left in a light-colored Infiniti and later identified Wilson in an in-person lineup. A jury convicted Wilson of first-degree murder and he received a 50-year sentence; no additional suspects were charged.

Does anyone have information about Adams, the scene that evening, or witnesses who saw the shooting?
