Antonio J. Buck, 32, was fatally shot on June 16, 2012, on a sidewalk in the New City neighborhood of Chicago. His killing occurred during a year that saw an exceptionally high number of homicides in the city, when Chicago recorded more than 500 homicides by year’s end amid rising gang violence and other community pressures.

The shooting on a public sidewalk underscores how gun violence affected everyday spaces in neighborhoods like New City, which were experiencing increased crime and gang activity at the time. Buck’s death formed part of the grim totals that made 2012 one of the deadliest years for Chicago and intensified efforts by community groups and law enforcement to respond to rampant gun-related crime.

If anyone knew Antonio Buck, witnessed the shooting, or has information that could help shed light on what happened that day, please come forward to authorities.
