3 Killed, Scores Injured in 50-Car Pileup in Penn.

Police say three people were killed in a weather-related pileup involving more than 50 vehicles on Interstate 78 in central Pennsylvania, the AP reports. Trooper Justin Summa says an unknown number of critically injured patients were flown to six or seven hospitals and 70 more were transported by ambulance to other facilities. He says several buses of stranded passengers were taken to a warming shelter at a firehouse in the area. The crash happened about 9:45am Saturday.

The pileup left tractor-trailers, box trucks, and cars tangled together across three lanes of traffic and into the snow-covered median. Trooper Adam Reed says investigators believe that "passing snow squalls played a role in causing the crash." Drivers are being urged to use caution due to the drifting snow and extremely cold temperatures. (More car accident stories.)
