Brett Hurt jumped in front of his best friend Gracie Evans Wednesday when a student rushed down the hall slashing people with knives in a Pennsylvania High School. "I heard her screaming and crying and I didn't know what was going on and then the pain in my back, I realized something happened," Hurt explained. Evans, put pressure on his wounds so he wouldn't bleed, an act, which he claims, saved his life. More than 20 students were injured during the mass stabbing.
