Darius Knowles was 27 when he was shot and killed on October 15, 2011, on Chicago’s South Side. The shooting occurred amid a wider spike in fatal shootings across the city that year; 2011 is described as having a significant number of gun homicides and was marked by ongoing violence in neighborhoods affected by poverty and gang activity.

The case is presented as part of a pattern that police say is difficult to solve because of factors such as retaliatory violence and limited witness cooperation.

Did anyone in the community have information about Darius Knowles or the circumstances of his death?
