Video: Knife-wielding student wounds 20 at PA high school

Armed with two knives, a 16-year-old student at Franklin Regional High School in Murraysville, Pennsylvania attacked his classmates this morning. Four students are in critical condition, while the suspect is in custody — after having been tackled by an assistant principal to end the attack:

Multiple people were stabbed at a high school in the suburbs east of Pittsburgh, officials said.

Emergency management spokesman Dan Stevens said four students were believed to be seriously injured when a student with a knife stabbed or slashed others, injuring as many as 20.

Stevens said not all of the 20 injured were cut by the knife, though most were. Some suffered scrapes and cuts in the mayhem that ensued at Franklin Regional High School on Wednesday morning. Stevens says it doesn’t appear any students suffered life-threatening injuries.

While Stevens said all the injured are between 14 and 17 years old, hospital officials told CBS Pittsburgh the patients they were taking in from the incident range from 15 to 60 years old.

The FBI also responded to the scene, but are emphasizing that they are in a support role only. This will be a local investigation.

The number of potential victims might have been higher, but a quick-thinking student hit the fire alarm. Another saved one of the severely-wounded victims by staying with her and keeping pressure on the injury to keep her from bleeding out:

Alyssa Finch, who said she is a student at Franklin Regional High School, told ABC News a fellow student pulled the fire alarm during the stabbing “because he knew what was happening … and he wanted the people to get out.”

KTLA in Los Angeles picked up on the story of the assistant principal’s action:

ABC continued its coverage with updates on medical treatment for the victims. All eight of the seriously wounded will need surgery, and three of them needed it immediately:
