Dion Miller, 26, was fatally shot in Chicago on January 23, 2012, one of many victims during an early-2012 surge in violence. His death came amid a year when the city’s homicide count rose sharply to 506, a dramatic increase that drew intense attention to crime patterns and policing.

Commentators at the time linked the spike in killings to several factors, including unusually warm weather and changes to police gang units, and Miller’s death was cited as part of that broader trend.
