Marvin Keyes, a 33-year-old African American man from Chicago, died of gunshot wounds on September 22, 2016, after having been hospitalized since he was shot on August 26, 2016, in the city’s West Town neighborhood. Before this shooting, Keyes had been acquitted in the murder of a postal worker.

The circumstances of the August shooting and the September death remain unclear. No arrests have been announced and the Chicago Police Department has not identified suspects or released a motive. Keyes’ death was one of many homicides during Chicago’s violent spike in 2016, a year that saw 762 homicides.
