This one in the small town of Bend, Oregon. Police say a 16-year-old boy from Bend got into an elementary school by shooting through locked doors using a long gun. Once inside, he shot and killed one teacher and three children, ages 5, 8, and 11. Two others were critically injured, including a 7-year-old and another teacher. I literally saw it as it happened. I saw him cross over the fence, jump over the fence with his gun. A witness says the shooter first opened fire on the driver of this truck, riddled with bullets in this photo. Police arrived three minutes after the first 911 call, where they found the suspect shot dead by a bystander. The governor of Oregon calling that person a hero.
