What motivated Wednesday morning's stabbing rampage at a Murrysville, Pennsylvania high school remains a mystery, with the teenage suspect's attorney calling him a good student who got along with others.
Sixteen-year-old Alex Hribal is being charged as an adult with four counts of attempted homicide, aggravated assault and a weapons charge in the stabbing attack that injured 21 students and a security guard at Franklin Regional High School outside of Pittsburgh. He's being held without bail. His attorney wants to move the criminal charges to juvenile court.
Police say Hribal used two ordinary kitchen knives to attack students up and down a hallway. At least five students were critically wounded, including a 17-year-old boy on a ventilator after a knife pierced his liver, missing his heart and aorta by millimeters.
Students say Hribal was quiet and shy and largely kept to himself. Defense attorney Patrick Thomassey has asked for a psychiatric examination. He said Hribal is remorseful, but didn't appear to understand the seriousness of his actions. Thomassey said Hribal's parents were "horrified" by the attack.
The school will likely reopen Monday.
