Authorities say a crash involving a school bus and a tractor-trailer on a western Pennsylvania interstate claimed the lives of the bus driver and a 14-year-old girl.
State police in Butler County said the crash occurred shortly after 4:30 p.m. Tuesday in the northbound lanes of I-79 in Muddy Creek Township.
Police said the 31-year-old man driving the bus and the 14-year-old girl who was riding on the bus were flown from the scene to hospitals and later pronounced dead.
Police reported other passengers taken to Children’s Hospital and UPMC Presbyterian.
A UPMC official told reporters that five students were treated for non-life-threatening injuries.
