Attorney: Boy was in daze knifing 22

PITTSBURGH — The 16-year-old boy accused of stabbing 22 people at his high school was dazed “like a deer in the headlights” hours later and doesn’t fully grasp what he did, his attorney said Thursday as he sketched out the beginnings of a possible mental-health defense.

Deepening the mystery of what set off the violence, attorney Patrick Thomassey said Alex Hribal had no history of mental illness or troublemaking, didn’t abuse drugs and was no outcast at school, where the lawyer described him as a B or B-plus student.

“In a case like this, it’s pretty obvious to me that there must be something inside this young man that nobody knew about,” Thomassey said.

The local prosecutor, meanwhile, said Hribal remained an enigma.

“We have very little information about him,” Westmoreland County District Attorney John Peck said, “except for the fact that he was a student, his age, and how he was as a student.”

Authorities seized the family’s computer as they searched for clues to Wednesday’s rampage at Franklin Regional High in Murrysville, about 15 miles from Pittsburgh.

Authorities said Hribal, using two kitchen knives, stabbed 21 students and a security guard before an assistant principal tackled him.

The slender, dark-haired boy who looks younger than his years was jailed without bail on four counts of attempted homicide and 21 counts of aggravated assault. Authorities are prosecuting him as an adult, but Thomassey said he will try to have the case moved to juvenile court.
