Antonio D Calhoun was 19 when he was fatally shot in Chicago on September 11, 2013. His death occurred during a year in which the city recorded a very high number of homicides, exceeding 400 for 2013, and came amid widespread gun violence that disproportionately affected young residents in many neighborhoods.

City efforts at the time included increased law enforcement and violence prevention programs, but the loss of young people such as Calhoun was described as highlighting the need for more comprehensive investment in services and opportunities for at-risk youth.

If anyone knew Antonio, his circle, or has information about the shooting on September 11, 2013, please come forward.
