Albert Abu, a 57-year-old Black man, was shot dead just after midnight on December 25, 2017, in Chicago’s Chatham neighborhood. At about 12:14 a.m. he was standing on the sidewalk in the 8100 block of South Wabash Avenue, steps from his home, when two males walked up and opened fire. Abu was struck in the head and chest, taken to St. Bernard Hospital, and pronounced dead at 12:28 a.m.

Police and the Cook County medical examiner documented the location, timeline, and manner of the attack. The killing came during a stretch of holiday violence that weekend; local reports counted multiple fatal shootings and numerous wounded, with Abu’s slaying the most recent reported fatality in that sequence. Area South detectives opened a homicide investigation, and authorities reported no one in custody; the two shooters who approached on foot have not been publicly identified.

If anyone has information about the shooting or remembers activity near the 8100 block of South Wabash Avenue that night, please share what you know with investigators.
