As many as 20 students were hurt when a classmate went on a stabbing rampage through the classrooms and halls of a high school outside Pittsburgh on Wednesday morning, authorities said.
The student suspect was in custody and being questioned by police, Dan Stevens, a Westmoreland County emergency management spokesman, told WPXI, the NBC affiliate in Pittsburgh. He said that the motive was unclear and that the injuries did not appear life-threatening.
Victims, as young as 15, were taken to four Pittsburgh-area hospitals. Two were in the operating room and a third was on the way, Dr. Chris Kaufmann, a hospital trauma director, told CNN. One hospital reported that it had patients as old as 60.
