Oregon mass shooter targeted special needs students

Authorities are investigating what prompted a 16-year-old to enter his former elementary school in Bend, Oregon, and open fire inside a special education classroom Thursday. Three children and a young teacher were killed in the shooting, and investigators are working to determine what led to the attack. The suspect, identified as Griffin J. John II, was a former student at Silver Rail Elementary and had previously been in special education, police said. Authorities say he fired through locked glass doors to enter the school before opening fire. A teacher tried to stop him by throwing a cellphone and tackling him, while a father of two students pursued the gunman and fatally shot him. A 7-year-old student and another teacher were also injured. The motive remains unclear.
