Teenager kills four at Oregon elementary school before being shot dead

A teenage boy shot and killed four people at an elementary school in Bend, Oregon on Thursday. The victims were three children, aged 5, 8, and 11, and one teacher. Police received the first emergency call just before 1 pm. The suspect, a 16-year-old local boy, first fired at a vehicle outside the school. He then shot at locked doors to force his way inside. Officers arrived quickly and the suspect was killed shortly after. It is not clear whether police or a bystander fired the fatal shot. The boy's name has not been released. School shootings remain a serious problem in the United States, and this attack has renewed debate about gun violence and school safety.
