Gregory Sims, 25, was shot and killed on September 6, 2016, in Chicago’s Uptown neighborhood near Wilson and Kenmore avenues. He was pronounced dead at Advocate Illinois Masonic Medical Center at 4:35 p.m. after suffering multiple gunshot wounds. Sims had been released from prison less than two weeks before his death.

Gregory’s younger brothers have been involved in criminal activity; one brother, Jabri Sims, has been arrested multiple times on charges including possession of a firearm with a defaced serial number, possession of controlled substances, and manufacturing and delivering cannabis. No arrests have been announced in Gregory Sims’ murder, and witnesses have been reluctant to come forward.

Does anyone who lived in Uptown at the time or who knew the Sims family have information about what happened that day?
