Gunman kills four at Oregon elementary school before bystander intervenes

A 16-year-old shot and killed three children and a teacher at Silver Rail Elementary School in Bend, Oregon on Thursday. The suspect, a former student, forced his way in by shooting at locked doors. The victims were aged 5, 8, and 11. At least one student and one teacher were critically injured.

A 36-year-old father was driving past the school when he saw the suspect shooting at a car in the parking lot. He took a legally owned handgun from his vehicle and followed the suspect inside. He shot and killed the attacker inside a special needs classroom.

Armed bystanders rarely stop active shooters in the United States. This case has drawn wide attention because a community member ended the attack.
