State Police say a 30-year-old Pittsburgh man was struck and killed by a tractor trailer while he was walking along the westbound lanes of the Pennsylvania Turnpike in Beaver County early Wednesday morning. They say Devin Glace was first struck by a tractor-trailer before being hit by two more vehicles just before 3 o’clock. The drivers of the tractor-trailer and one of the other two vehicles stopped. However, police said the third driver kept going. Authorities said the vehicle of the driver who did not stop was described as a “green Peterbilt long wood trailer with grain on top.” Anyone with information about that vehicle is asked to call Pennsylvania State Police in Gibsonia at 724-443-5907. All westbound lanes of the turnpike were closed between Cranberry and New Castle until about 8 a.m. (Photo: WPXI)
