Aaron Perez, an 18-year-old from Chicago, was shot and killed on November 15, 2016. His death occurred during a year when Chicago recorded 764 homicides, the city’s highest total in almost two decades, and when gun violence disproportionately affected young men in many neighborhoods.

The Crime Lab at the University of Chicago analyzed these patterns and highlighted the need for sustained interventions to prevent similar tragedies.

If anyone knew Aaron, his neighborhood, or has information about the shooting on November 15, 2016, please come forward.
