SOUTH HUNTINGDON TOWNSHIP (KDKA) — Students at Yough Sr. High School in Westmoreland County are mourning the death of another classmate.

Erika Stefan, 15, was killed by a train Sunday morning as she walked along the tracks in Smithton.

The coroner says she was wearing headphones and probably didn’t see or hear the CSX train.

Another Yough student, 16-year-old Taylor Fronhofer, was killed in a car crash on Nov. 27.
