Abstract
This study investigates the prevalence of homicide as an urban phenomenon. It analyzes data available for the City of Chicago, Illinois. In the year 2003, Chicago led the nation in homicides. Police there attribute it to a deadly combination of street gangs, guns, and drugs. Such an approach is far too simplistic. An effort is made with this study to identify determinants of patterns of murders that persisted for more than a decade in Chicago, despite the decrease in violent crime across the nation and eventually Chicago. African American males were an exceedingly disproportional number of the victims and the offenders. This study finds two distinct types of homicide patterns, one involving recidivism in the criminal justice system and the other no prior exposure.
