GREENSBURG, Pa., June 2 (UPI) -- The teenager charged with injuring 21 people during a knife rampage at his Pittsburgh-area high school waived a preliminary hearing Monday.
Alex Hribal's preliminary hearing had been set for Wednesday. It was originally scheduled for early May, but his lawyer, Patrick Thomassey, asked for a postponement.
Thomassey filed a notice with the judge waiving the hearing. Hribal is scheduled to be arraigned in July.
Hribal, 16, was arrested after he allegedly attacked 20 students and a security guard at Franklin Regional High School in Murrysville on April 9. He has been charged as an adult with 21 counts of attempted murder and aggravated assault and one of possession of a knife on school property.
Hribal is being held in the Westmoreland County Juvenile Detention Center.
