Jeffery Demetrius ’King Lou’ was 34 when he was shot and killed on January 27, 2017, in Avalon Park on Chicago’s South Side. Police say the killing followed an argument on Stony Island Avenue during which two men struck him to the ground and then opened fire. He was taken to the University of Chicago Medical Center and pronounced dead; the autopsy the next day ruled his death a homicide.

Investigators recovered surveillance video frames showing the two suspects entering a Citgo station on Stony Island Avenue. Despite those images and an appeal for help, no arrests have been announced. The shooting is noted amid a rise in violence in the 4th police district, where shootings and murders increased compared with the previous year.

Anyone with information that could identify the two men or assist the investigation is asked to contact the Chicago police with tips.
