The Pennsylvania teenager who is accused of stabbing and slashing schoolmates in an early morning rampage at his high school will be charged as an adult, authorities confirmed.
Alex Hribal, 16, will face four counts of attempted homicide and 21 counts of aggravated assault.
The Murrysville, Pa., teen allegedly stabbed or slashed 20 fellow students and a security guard at Franklin Regional Senior High School on Wednesday morning minutes before the school's opening bell.
At least five students were critically wounded, including a boy who was on a ventilator after a knife pierced his liver, missing his heart and aorta by only millimeters, doctors said.
The motive is under investigation.
