Chazelle Maurice Hayes, 25, was fatally shot in the Homan Square neighborhood on Chicago’s West Side on July 18, 2015. The shooting happened about 1 a.m. after a block-party barbecue where Hayes had celebrated his birthday days earlier. A light-colored van pulled up and someone inside opened fire; Hayes was struck in the chest and arm and later pronounced dead at Mount Sinai Hospital. An 18-year-old man was also wounded.

Police said multiple shootings occurred in the area that night and were being investigated as separate incidents; officers were nearby but no one was in custody immediately after the shootings. In March 2016, 26-year-old Timothy Ward of Carpentersville was charged with first-degree murder in connection with Hayes’ killing. Hayes was a father of four, known for athleticism, a sense of humor and rapping under the name The Mayor; his family described their grief and called the violence senseless.

If anyone has information about what happened that night or knew Hayes, please share what you know.
