🚨 SCHOOL SHOOTER IDENTIFIED: 16-year-old John J. Griffin has been identified as the gunman who killed three children, ages 5, 8, and 11, and a teacher at an Oregon elementary school. Now, the first reported photos of the teenager have emerged. BEND, OREGON — Griffin reportedly used a shotgun purchased by his mother to shoot through locked doors at Silver Rail Elementary School before opening fire. A 7-year-old child and a 54-year-old teacher were also critically injured. The massacre ended when Kaylub Giamanco, a father of two students at the school, followed the gunman inside and fatally shot him. Investigators are still working to establish a motive and determine how Griffin obtained access to the weapon. Three children went to elementary school Thursday and never came home. The youngest was just 5 years old. A father stepped in to stop the killing. Now investigators need to establish how a 16-year-old obtained the shotgun used to carry it out.
