Alejandro Brown, 26, was fatally shot in Chicago on May 21, 2012. His death occurred during a year of sharply elevated gun violence in the city, when recorded homicides topped 500 and neighborhoods across Chicago were coping with a sustained rise in deadly shootings.

Reports note investigations into cases that year often encountered limited witness cooperation, which hindered efforts to identify and prosecute perpetrators. Brown’s killing added to a painful pattern that left families and communities grieving as the city struggled to reduce its homicide rate.

Did anyone in Chicago remember Alejandro or have information about the shooting?
