That marked the most homicides in a single day in Chicago in more than a decade, according to a Tribune analysis of department data. The worst day previously was July 5, 2003, when Chicago saw 10 homicides, the analysis found.

The spate of violence comes in the waning days of summer as hot and humid weather sent city residents outdoors before Chicago Public Schools classes begin next week. The latest violence has added to a year that already has seen homicides and shootings rise in Chicago and in many big cities across the country.
