Christopher Williams was 23 when he was shot and killed on May 13, 2019, while walking in the Roseland neighborhood of Chicago.

Family members say Christopher had no known gang ties. He worked at the University of Chicago Medical Center and was a devoted father, and his mother Vickie Armstrong-Williams has been publicly urging progress in the investigation. A Ring doorbell video captured the moments before the shooting, and the murder weapon was later turned in to police, but investigators have not been able to link it to a suspect and no arrests have been announced.

Anyone who knew Christopher, saw that gray Ford Fusion in Roseland on May 13, 2019, or has information about the people involved is asked to come forward.
