Christian Pichardo, 28, was shot and killed on a South Chicago sidewalk on May 23, 2011. Authorities described the killing as a targeted attack, but few specifics about motive or suspects were released.

The investigation was hampered by a lack of witness cooperation, a problem the report links to fear of retaliation in neighborhoods affected by persistent gun violence. Pichardo’s death was one of many that contributed to Chicago’s elevated homicide total in 2011 and is presented as part of broader issues of gang activity, community instability, and long-term underinvestment in the area.

Does anyone who lived in South Chicago in 2011 remember seeing or hearing anything about this shooting, or know Christian Pichardo?
