Kiyon R Evans was 15 when he was shot and killed on October 9, 2015, while standing outside in Chicago’s Austin neighborhood. He was struck by gunfire during an episode of street violence that has affected many of the city’s under-resourced neighborhoods.

Family and friends remembered Kiyon as kind, funny and often the class clown — a high school student with his whole life ahead of him. Memorial posts show relatives lighting virtual candles and leaving messages about the emotional toll his loss has taken. Despite community efforts and calls for justice, the case remains unsolved, leaving his family without closure.

If anyone knew Kiyon, saw activity in Austin on October 9, 2015, or has information that could help, please come forward.
