Seventeen-year-old Vonzell Banks was shot and killed on July 3, 2015, at Hadiya Pendleton Park in the Bronzeville neighborhood of Chicago. Banks was playing basketball with his cousin and friends when a gunman in white approached the court, fired multiple shots, and fled in a white SUV. Vonzell was struck in the back and died after being taken to Stroger Hospital; his 19-year-old cousin suffered a gunshot wound to the foot.

Vonzell was remembered by family and community members as cheerful, devout, and musically gifted — he played drums and sang at local churches and was about to start a summer job and his senior year at Dunbar Vocational Career Academy. The family held a vigil at the park, releasing balloons and calling for an end to the violence.

Witnesses described the shooter and the escape vehicle, but no arrests were made immediately and the investigation remained unresolved for some time. Does anyone have information that could help bring clarity to what happened that afternoon?
