Marquise Chandler, a 20-year-old African American man, was fatally shot on July 8, 2013, while in a vehicle in Chicago’s West Garfield Park neighborhood. The shooting is presented as part of wider gun-violence problems in that area.

Investigators did not identify suspects or make immediate arrests after the killing. Reports say the probe struggled with a lack of witnesses and limited concrete evidence, and the case has seen few developments over the years. Chandler’s family and members of the community continue to seek justice amid ongoing frustration over the unsolved death.

Does anyone who lived in West Garfield Park in July 2013 or who may have information about that night have details to share with investigators?
