District Attorney John Peck says he previously offered Hribal 30 to 60 years in prison for slashing his way through the hallways of Franklin Regional High School in Murrysville on April 9, 2014.

But Peck said if Hribal pleads guilty next week, he’ll enter a general plea. That means a judge will decide Hribal’s sentence for 21 counts each of attempted homicide and aggravated assault, plus a weapon’s charge.
