At least 20 people were injured this morning during a stabbing at Franklin Regional High School in Murrysville, Pa. Four of the victims were airlifted to local hospitals. One person—a student from the school—is in police custody.
There are conflicting reports about the ages of the victims. Westmoreland County emergency management spokesman Dan Stevens told CBS Pittsburgh that all 20 were students at the school, though local hospitals have reported receiving victims between the ages of 14 and 60.
Murrysville police Chief Thomas Seefeld identified the adult victim as a security guard at the school.
Jeff Dahlke with the security company who provides security for Franklin Regional High School says the suspect was armed with two knives.
"The alarm went off, and students started rushing outside, the security guard outside rushed in, and came upon his supervisor, and a vice principal who had the suspect in custody on the ground and was trying to control him, and try to get the weapons away from him," Dahlke said.
Police say that security guard was stabbed in the abdomen
UPDATE 10:56 am: Nineteen of the 20 victims were students; the other vicim was a faculty member. The suspect, a 16-year-old sophomore, was carrying two knives and was tackled by the school's principal. Police still don't know the motive for the attack.
