Twenty people were injured during a stabbing rampage at a Pennsylvania high school early Wednesday, authorities said.
A male student brandishing a knife spread terror before the school day began in several classrooms and a hallway of Franklin Regional High School in Murrysville — a typically peaceful community.
Some students suffered life-threatening injuries, though all are expected to survive.
Most of the injuries were "stab wounds to extremities," according to Dan Stevens, deputy emergency management coordinator for Westmoreland County Department of Public Safety. Others were scrapes and bruises.
Police and paramedics rushed to the scene in Murrysville, which is about 18 miles east of Pittsburgh, after the first call came into 911 about 7:13 a.m.
A male suspect, who has not been identified yet, is in custody and being interrogated by police.
High school students were evacuated to the middle school after the news broke. Parents were then told to report to the town's elementary school to reunite with their kids.
Others were told their children were taken to one of several nearby medical centers. Four victims had to be airlifted from the scene.
"We have 8 patients being taken into Forbes. Their ages range from 15 to 60," Jesse Miller, communication officer for Forbes Hospital, told the Daily News. "I can also confirm that we have another patient being taken to our parent hospital, Allegheny General Hospital."
Others were brought to UPMC Presbyterian.
Morris Hundley, the father of a high school student, moved to Murrysville so he could raise his daughter in a safe environment. He told CBS Pittsburgh his daughter he spoke to her daughter over the phone. Her best friend was among the victims.
“She was just frantic. I never heard her talk like that,” he said to the station. “That’s why I got off the phone right away and came here as soon as I could.”
Hundley added that the first thing on his agenda is to give his daughter a big hug. The scene is reportedly secure and currently on lockdown.
The school district posted the following statement on its website:
"A critical incident has occurred at the high school. All elementary schools are cancelled, the middle school and high school students are secure. Additional information will be released as soon as possible. Please keep our campus clear of traffic."
