Ricardo Carlin, 22, was fatally shot in Chicago on April 22, 2013. His death was recorded among the city’s 2013 homicides, a year that saw 415 killings as Chicago wrestled with persistent gun violence and outbreaks of conflict between rival groups in several neighborhoods.

The case is presented against a backdrop of systemic problems cited in city crime data—limited economic opportunity, scarce resources for young people, and conditions that can feed gang recruitment and recurring violence. Carlin’s death is described as one of many tragic losses of young men caught up in those tensions, and as part of the official statistics that local law enforcement and community groups were working to address through initiatives such as community policing and outreach.

If anyone knew Ricardo, his routine, or what happened on April 22, 2013, please share information that could shed light on the case.
