On the night of August 18, 2017, 59-year-old Kenneth Gantz was shot in the bar area of Skyway Park Bowl in the Skyway area of Seattle. Multiple gunshots struck two men shortly before 1 a.m.; 24-year-old Dennis Robinson was found dead in a back alley often used by smokers, and Gantz was taken to Harborview Medical Center after emergency surgery but later died of his injuries. The King County Medical Examiner’s Office ruled both deaths homicides.

King County Sheriff’s detectives reviewed surveillance from inside the bowling alley and concluded the shooting was not random. Footage showed a third individual described by investigators as a person of interest, though no public description or positive identification was released. It was not clear whether a third party committed the killings or whether the violence stemmed from a dispute between Gantz and Robinson. No arrests had been announced and the investigation remained open.

Anyone who knew Kenneth or has information about that night is asked to contact investigators.
