Franklin Regional High School near Pittsburgh

*Emergency crews in Pennsylvania responded Wednesday morning to reports of multiple stabbings at a Westmoreland County high school.

Authorities said that one suspect, a 16-year-old male student, is in custody following the 7:20 a.m. incident at Franklin Regional High School in Murrysville, according to WPXI. Police said the suspect entered the school wielding a knife before the first class of the day was scheduled to begin.

As many as 20 students were hurt in the attack. Dr. Chris Kauffman, the trauma director at Forbes Regional Hospital, characterized some of the teenage victims’ wounds to the chest, back, and abdomen as life-threatening, according to NBC News.

Authorities said that not all of those injured were stabbed by the suspect. Some suffered wounds amid the rush to flee the halls of the building.

One victim was an adult, authorities said, a security guard who was being treated for a medical condition, not a wound suffered during the attack.

After being taken into custody, the suspect was transported to an area hospital for treatment of injuries to his hands, Murrysville Chief of Police Thomas Seefeld said in a press conference.

Murrysville is approximately 15 miles from Pittsburgh.

Parents are instructed to pick up their children at Heritage Elementary school, Murrysville police announced.
