A student flashing two knives went on a stabbing rampage through the classrooms and halls of a high school outside Pittsburgh on Wednesday morning, authorities said. At least 19 students and a security guard were hurt, some with life-threatening injuries.
The suspect, a 16-year-old sophomore, was in custody and being questioned by police, authorities said. His motive was unclear, said Dan Stevens, a Westmoreland County emergency management spokesman.
The first photo of the suspect emerged several hours after the mayhem. NBC News is blurring the face of the teen in the photo, from the Pittsburgh Tribune-Review, because of his age. He had not been charged or identified.
The student was “flashing two knives around” as he moved through the classrooms and a first-floor hallway, said Thomas Seefeld, the Murrysville police chief. A principal tackled the stabber, he said. The security guard suffered a stomach wound.
The attack happened at Franklin Regional High School, in the suburb of Murrysville, just after doors opened for the day. A student described panic in the halls.
“I was walking into the school and a stampede of people were running after me,” said the student, Kari Lee, who said several of her friends had been knifed. “They were screaming, ‘Go to your cars! Go to your cars! Someone is stabbing people!’”
