Asaan Williams was 18 when he was fatally shot at Seven Oaks Park near 38th Street and Kensington Avenue in Kansas City, Missouri, on Friday, March 13, 2015. The shooting occurred in daylight and prompted an immediate police investigation.

Authorities released a photo of a 2003 Chevrolet Impala seen leaving the park around the time of the killing and asked for help identifying the car and its occupants. Witnesses were reportedly reluctant to come forward, and no arrests or public suspect identifications have been made.

Asaan’s family has pushed for changes in the wake of his death; their advocacy helped bring surveillance cameras to Seven Oaks Park, and they maintain a memorial there. Does anyone who was in the area that day or who recognizes the vehicle have information that could help close this case?
