A 16-year-old sophomore suspect has been taken into custody after a stabbing rampage at Franklin Regional High School, right outside of Pittsburgh. At least 19 students and one security guard have been reported with injuries, some life threatening. The suspect made his way through hallways and classrooms flashing two knives. As of now, his motive has not been identified. Thomas Seefeld, the Murrysville police chief, said that the suspect was tackled by a principal. The suspects name has not been released due to his age and lack of charge.
