The stabbing rampage began just after school started, when the alleged assailant started stabbing and slashing students with two kitchen knives.
He had injured one security guard and 21 fellow students by the time he was confronted by Assistant Principal Sam King, who tackled him to the ground.
Though four people suffered serious injuries, all the wounded are expected to survive the incident.
Hribal's is currently in a Westmoreland County juvenile detention center. His preliminary hearing is set for April 30.
