Armed bystander kills teen gunman after Oregon school shooting kills four

A 16-year-old shot a vehicle outside Silver Rail Elementary School in Bend, Oregon, on Thursday, then forced entry by shooting at locked doors. Three children, ages 5, 8 and 11, and an adult teacher were killed, and two others critically wounded. An armed bystander, reportedly a student's father according to dispatch audio, pursued the suspect inside and killed him. Police say they do not yet know if he had any connection to the school.
