Aquoness Cathery Jr., 24, was fatally shot by a Chicago police officer on November 29, 2017, in the Washington Park neighborhood. Officers responding to a shots-fired call encountered Cathery in the 6100 block of South King Drive around 2:15 p.m.; police say he was carrying a handgun and a foot chase followed. Officer Julio Garcia fired his service weapon on a back porch; Cathery was taken to Stroger Hospital and died the next day.

Cathery’s mother, Lashundia Key, filed a Cook County lawsuit against Officer Garcia and the City of Chicago, alleging Garcia recklessly killed her son and intentionally disabled or turned off body-camera audio to hide commands, warnings, and gunshots. Civilian Office of Police Accountability footage released shows Garcia pursuing Cathery through an apartment onto a shared porch and Cathery appearing to hold a gun, but the footage lacks audio in the crucial moments. The lawsuit also alleges discrepancies in the police account, saying Cathery was running away when shot and that Garcia continued firing as Cathery ran down stairs, with one bullet reportedly passing through a neighbor’s living room window.

Are there witnesses or additional footage from that block who can clarify what happened on the porch and why the camera audio is missing?
