Two people were killed and four others, including children, were injured in a head-on crash on the Pennsylvania Turnpike late Saturday night. State police say 76-year-old William Paxton, of Pittsburgh, was driving eastbound on the Pennsylvania Turnpike in the westbound lanes when he slammed head-on into a car driven by 36-year-old Andrew Sworan, of Chagrin Falls, Ohio. The accident happened at the 8 mile marker just across the state line. Paxton and Sworan both died at the scene. Paxton’s wife was taken to a Pittsburgh hospital with suspected serious injuries. A 40-year-old woman in Sworan’s vehicle was hospitalized with possible injuries, along with a 4-year-old boy. A 5-year-old girl was not injured. Authorities say Paxton had traveled on the wrong side of the highway for eight miles before the accident happened. State police are trying to determine why. The highway remained closed in the westbound direction for approximately four hours before reopening early Sunday morning.
