Anthony Josue Collazo, 21, was shot and killed in Chicago on July 10, 2012. His death occurred during a year when the city recorded an unusually high number of homicides, surpassing 500 by year’s end.

Reports place Collazo’s killing in the broader context of neighborhood violence that year, tied to conflicts among rival groups and long-standing social problems such as economic deprivation and limited community resources. His death is presented as one of many that underlined how gun violence affected young people and entire Chicago neighborhoods in 2012.
