Keith A. Handson, 33, was stabbed to death the night of July 7, 2011, at the intersection of Independence Avenue and Bales Avenue in northeast Kansas City, Missouri. Officers arriving about 11:36 p.m. found Handson with apparent stab wounds; he died despite emergency efforts and was counted among the city’s homicides for 2011.

Investigators never announced an arrest. In August 2011 the Kansas City Police Department and federal partners — including the DEA, FBI, and ATF — named Handson’s death among several unsolved cases during a large multi-agency operation that sent hundreds of officers and agents door-to-door and urged tips via a hotline.

Handson is survived by family including his brother Aaron J. Ray, who was later noted as having been preceded in death by Keith. What information can readers share that might help shed light on what happened that night?
