Mack Harris was 19 when he was found unresponsive with a gunshot wound to the chest on December 24, 2020, in the 3400 block of West Ohio Street in Humboldt Park, Chicago. Officers located him about 3:10 p.m.; he was taken to Stroger Hospital and pronounced dead. The Cook County medical examiner ruled his death a homicide and Area Four detectives opened an investigation.

Known as Man-Man, Mack grew up on Chicago’s west side and attended Tilton Elementary and Michelle Clark High School. Friends and family remember him as smart, caring, funny and a fan of video games. An arrest was reported on May 12, 2021, when 27-year-old Deandre Watson was charged with one felony count of first-degree murder in connection with Mack’s killing.

Anyone who knew Mack, was in the Humboldt Park area that afternoon, or has information about the shooting is asked to come forward.
