Knife stabbing rampage at Pennsylvania high school injures 22
Twenty-two people were injured when a 16-year-old boy went on a stabbing rampage at a Pennsylvania high school early Wednesday, leaving five students in critical condition, authorities said. Sophomore Alex Hribal allegedly brandished two large knives in the bloody attack as he darted between several classrooms and down a hallway at Franklin Regional High School in Murrysville - a typically peaceful community about 18 miles east of Pittsburgh.
