An elderly Belle Vernon woman was killed Wednesday morning when her car collided with a tri-axle truck on Route 51 north in Rostraver Township. Authorities say 86-year-old Anna Mae Selembo was killed when the two vehicles collided at Gallitin Road and Route 51 just before eleven o’clock. Police say the driver of the truck, 61-year-old Roy Waggoner of Monongahela, was not hurt. Authorities say their investigation indicates that Selembo’s car drove directly into the path of the truck. That section of the roadway was closed for about three hours.
