▶ Watch Video: Fiery pileup kills at least 3 in Pennsylvania The death toll in the massive Monday pileup on a snowy Pennsylvania highway has risen to six people, the Pennsylvania State Police said Wednesday. An additional 24 people were injured in the devastating crash, which officials said involved 80 vehicles and sparked a “large fire.” There was an active snow squall — an intense burst of snow that often drastically reduces visibility — at the time of the pileup on the northbound side of I-81, a spokesperson for the state police said Wednesday. A video taken by a witness at the scene showed multiple vehicles crashing into each other amid heavy snowfall, with some drivers attempting to pull off the highway for safety.
