MURRYSVILLE, Pa. (AP) — A school police officer has been treated and released from a hospital, after being injured while ending a stabbing attack at a high school near Pittsburgh on Wednesday.
Police said a 16-year-old boy, who was armed with two knives, began stabbing and slashing other teens at the school on Wednesday morning, leaving as many as 19 students injured.
Four of them suffered serious wounds, but hospital officials said all are expected to survive.
The teen suspect is in custody, and investigators are trying to determine a motive.
