CHICAGO (AP) — A Chicago police officer fatally shot a 24-year-old man who authorities said pulled a gun while running away, prompting questions from the man's family about why the encounter turned deadly. Sgt. Rocco Ailoto said the "armed confrontation" occurred around 8:10 p.m. Wednesday in the Bronzeville neighborhood on the city's South Side as officers conducted a narcotics investigation. He said the suspect fled on foot when officers approached.
