Johnnell Johnson, 37, was shot and killed on August 23, 2016, in Chicago. His death occurred during a month that later recorded over 90 homicides, a peak described as the deadliest month in the city in two decades and part of an especially lethal year that ended with 764 murders in 2016.

Analysts have linked the spike that summer to reduced proactive policing measures after increased scrutiny of police practices, alongside longstanding socioeconomic problems in many neighborhoods.

Community groups and law enforcement have since pursued interventions aimed at reducing shootings, and researchers such as the University of Chicago Crime Lab have studied the surge to inform prevention strategies. Does anyone have information about Johnnell Johnson, the circumstances of August 23, 2016, or contacts who might remember him?
