Miguel A. Vazquez, 21, was fatally shot just before midnight on July 31, 2010, while sitting on a porch on West School Street in Chicago’s Wicker Park neighborhood. He and another man were involved in an argument with an unknown suspect, who opened fire and then fled through an alley and into a waiting vehicle. The second victim survived and was hospitalized; Miguel died of his wounds.

The killing occurred amid a broader rise in gun violence across Chicago in 2010, a time when territorial disputes and gang-related conflicts were cited as drivers of deadly confrontations even in neighborhoods known for arts and development like Wicker Park. The case underscores how quickly a dispute escalated to lethal force and adds to the year’s homicide total.

Anyone who witnessed the shooting, saw a vehicle leave the alley that night, or has information about the suspect or the waiting vehicle is asked to come forward.
