A western Pennsylvania man was sentenced on Monday to up to 60 years in prison for stabbing 20 fellow students and a security guard with two kitchen knives in a high school rampage in 2014.
Alex Hribal, now 20, was 16 years old at the time of the attack at Franklin Regional High School in Murrysville, Pennsylvania, 18 miles east of Pittsburgh. He suffered from pre-schizophrenia symptoms, according to court documents.
