Santiago Delgado, 46, was shot and killed in Chicago on June 20, 2012. The shooting happened just after midnight and appears to have been a targeted attack. Reports say Delgado and another man were struck in the chest; a woman in her mid-50s was also injured. Delgado died at the scene.

His death came during a year of sharply rising homicides in Chicago, when the city saw a large increase in killings and law enforcement efforts such as increased patrols and community policing were in place. Witness noncooperation was reported as an obstacle in many cases that year. Delgado’s killing is one of several incidents that reflected the broader pattern of violence affecting Chicago neighborhoods in 2012.
