Murrysville, Pa. -- (NBC News) Three of the 21 people stabbed Wednesday in a brutal rampage inside Pennsylvania's Franklin Regional High School remain in intensive care.
All are expected to survive, and many are crediting their friends and classmates with saving their lives.
16-year-old Alex Hribul, a sophomore, is charged with attempted homicide and aggravated assault.
From his hospital bed, Brett Hurt recounted five terror filled minutes when Hribul, armed with two kitchen knives, slashed his way through everyone in his path.
"When people saw blood, they started screaming, and when they saw I got hit, they started running," Hurt says.
Hurt isn't sure when he'll be able to return to that hallway where he was stabbed, but has a wish for his attacker.
"I just hope that everyone, that I can forgive him and everyone else who got hurt can forgive him," he says.
What set the suspect off remained an open question Thursday. Hribal’s lawyer said that the teenager was not considered “a loner or a weirdo,” did not use drugs and had no history of mental health problems.
“People don’t just snap. There’s a buildup that takes place,” said Clint Van Zandt, a former FBI profiler. “There was some final catalyst, one last psychological straw that got pulled from under this guy.”
One day after the rampage at Franklin Regional High School outside Pittsburgh, little was known about the suspect. His lawyer, Patrick Thomassey, said that he stands 5 feet 3 inches and weighs 110 pounds. He did not keep a cellphone.
Thomassey, who spoke with Hribal on Wednesday and spent hours with his family, described the teenager as a soft-spoken, shy, “nice young man.”
