RAYBURN TOWNSHIP, Armstrong County — State police are investigating a vehicle crash Thursday morning that killed a woman in a wheelchair in central Armstrong County.

The fatality occurred around 5:22 a.m. at Route 28/66 and Troy Hill Road in Rayburn Township. The victim was struck by a northbound vehicle while crossing Route 28/66.

The Armstrong County coroner’s office identified the woman as 53-year-old New Kensington resident Sylvia Jean Denslow.

Denslow, who was in a wheelchair, was struck by a Ford F-150 pickup truck driven by Roger Crissman of Cowansville. Denslow was crossing the road after leaving the Bench Racers Store.

Driving conditions were poor, according to a coroner’s office news release, with heavy fog limiting visibility.

Coroner Brian Myers pronounced Denslow dead on the scene. Toxicology results will not be available for several weeks, according to Myers’ office.

The road was closed in both directions for a little more than three hours after the crash for an accident reconstruction investigation. The road reopened around 8:45 a.m.

Along with state police and the coroner’s office, Rayburn Township Volunteer Fire Department, Kittanning Township Volunteer Fire Department, Kittanning Ambulance Service and the Pennsylvania Department of Transportation also responded to the scene.
