Donald Dockery, 51, was fatally shot in Chicago on November 1, 2016. His death occurred during a year of sharply increased violence in the city, when Chicago recorded over 750 homicides and more than 1,100 additional shooting incidents compared with the previous year. Much of the surge was concentrated on the South and West sides and was linked in reports to high availability of illegal firearms and heightened tensions over social injustices. Police efforts that year included seizing thousands of illegal guns, but widespread gun violence nonetheless continued to afflict many communities, including the one where Dockery was killed.
