Twenty people were injured — four seriously — in multiple stabbings this morning inside a high school in Western Pennsylvania, reports the Pittsburgh Post-Gazette. Most of the injured were students. Westmoreland County public safety spokesman Dan Stevens said a male suspect, also a student, is in custody and was being questioned by police. None of the injuries at Franklin Regional High School in Murrysville was life-threatening, he said.
Those seriously injured were flown to hospitals by medical helicopter. Just before 7:15 a.m., a school resource officer asked for medical assistance at the school for a stabbing. The students were injured in several first-floor classrooms and in the hallways before the classes started.
