*Source Data & Editor’s Note
Posted on January 27, 2013
We compile our own dataset using the following sources: Chicago Tribune, Chicago Sun-Times, DNAInfo Chicago, Chicago Redeye Homicide Tracker, NBC5 Chicago, City of Chicago Data Portal and CPD CLEARMAP.
Editor’s note: A homicide, regardless of type, within the city limits of Chicago counts towards our total metric. CPD-involved, ISP-involved and justifiable homicides all count. Reckless homicides may count if the Medical Examiner rules that the cause of death was a homicide. Suicides do not count. Additional definitions can be found on the Glossary page.
