Robert E. Barr, 29, was killed in Chicago on May 4, 2011. His death is recorded as part of the city’s elevated homicide total for 2011, a year marked by multiple gun-related fatalities across Chicago neighborhoods.

Public homicide data from the Chicago Police Department’s CLEAR system records incidents at the block level to protect victim privacy, so the case entry for Barr contains limited location and incident detail.

Anyone who knew Robert Barr or has information about the May 4, 2011 incident is urged to come forward.
