Pennsylvania teen charged after wounding 22 in stabbing spree at high school

the identity of the suspect as Alex Hribal

A 16-year-old boy was charged Wednesday after he allegedly stabbed 21 students and an adult -- leaving four seriously injured -- during an early-morning attack at a high school near Pittsburgh, authorities said.

Fox News has confirmed the identity of the suspect as Alex Hribal, a student at Franklin Regional Senior High School, the scene of the stabbing spree. The sophomore was being charged with four counts of attempted homicide, 21 counts of aggravated assault and one count of possessing a prohibited weapon on school property, according to a criminal complaint released by Westmoreland County District Attorney John Peck.

Westmoreland County Sheriff Jonathan Held described Hribal as quiet, adding that the teenager had not been talking to authorities since he was taken to be arraigned before a district judge Wednesday. He was jailed without bail.

Police said Assistant Principal Sam King tackled the boy and disarmed him, and a Murrysville police officer who is regularly assigned to the school handcuffed him.

King's son told The Associated Press that his father was treated at a hospital, though authorities said he was not knifed.

"He says he's OK. He's a tough cookie and sometimes hides things, but I believe he's OK," Zack King said. He added: "I'm proud of him."

As word of the incident spread and children streamed out of the school, parents told FoxNews.com they were shocked by the attack — and one district official expressed relief that it was carried out with a knife rather than a gun.

At a late afternoon press conference, Murrysville Police Chief Thomas Seefeld said "one or two" of the victims remained in critical condition.

He also said the suspect had been armed with two eight-to-ten inch straight knives.

“Nobody’s ever prepared for something like that as a parent,” Matt Provenzo, who had dropped his son, Mark, off at the high school moments after the stabbings, told FoxNews.com. "As he got out of the car, you could see students exiting the building and that the fire alarm was pulled … There were a few students who were visibly upset."

And I will set the Egyptians against the Egyptians: and they shall fight every one against his brother, and every one against his neighbour; city against city, and kingdom against kingdom.

John 8:44

Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
