(Murrysville, PA) -- The suspect in that terrifying mass stabbing at a Pittsburgh-area high school is being charged as an adult with four counts of attempted murder and more than 20 counts of aggravated assault. The attorney for 16-year-old Alex Hribal is trying to move the case to juvenile court.
Patrick Thomassey talked to ABC's "Good Morning America." Authorities say Hribal stabbed at least 20 fellow students and a security guard in yesterday's bloody attack. The rampage at Franklin Regional Senior High School was finally ended by the school's assistant principal who managed to tackle the teen and hold him until a school resource officer could handcuff him. Classes are cancelled for the next few days as the investigation unfolds and students and staff try to come to grips with the shocking violence many witnessed firsthand.
