David A. Haynes, 36, was killed in Chicago on April 27, 2017. The homicide occurred on the city’s South Side during a year when Chicago was experiencing a sharp rise in gun violence that affected many neighborhoods and claimed hundreds of lives.

The context provided notes that many 2017 homicides involved firearms, disproportionately impacted young men from economically disadvantaged areas, and were complicated by issues such as illegal guns, gang activity, poverty, and limited access to services. The Chicago Police Department’s data indicate investigations are often hindered by a lack of witness cooperation, which has slowed resolution of many cases from that period.

Does anyone who lived on the South Side in April 2017 or who knew David Haynes have information that could help clarify what happened?
