Yesterday morning, as students were arriving to Franklin Regional High School, 16-year-old Alex Hribal went on a stabbing spree, wounding 21 students and one adult. According to witnesses, Hribal ran through the hallway on the first floor of the school, stabbing students with two kitchen knives, estimated to be between eight and ten inches long. He was eventually tackled by the assistant principal and handcuffed by a school security officer, who also serves in the Murrysville Police Department. The injured adult is another security guard, who was stabbed in the abdomen. During the incident, a student pulled the fire alarm to alert his peers.
