An Oregon teacher bravely fought a teenage gunman, attempting to wrestle a shotgun away from him before an armed bystander intervened and fatally shot the suspect multiple times. The attack occurred Thursday at Silver Rail Elementary School in Bend.

Police confirmed the details of the tragic event on Friday, identifying the 16-year-old suspect as Griffin J. John II, a former student at the school who had attended special education classes there. The teacher's courageous actions and the bystander's quick thinking are credited with preventing a potentially much higher casualty count.

The teacher, identified as 25-year-old Meghan Lambert, threw her mobile phone and then tackled the suspect as he opened fire on a special educational needs class. During the struggle, a bystander, identified by his family as 36-year-old carpenter Kaylub Giamanco, ran into the school. Giamanco, a father of two girls attending the school, had been driving past when he witnessed the suspect firing in the car park and then shooting through a window.

Giamanco, who legally carried a concealed .40-caliber pistol in his vehicle, entered the school and confronted the suspect. Police stated that Giamanco then opened fire, killing the 16-year-old.

Four people were killed in the attack: five-year-old Rhoam Summer, teacher Meghan Lambert, and two other students aged eight and 11 whose families requested their names not be released. Two others were injured: a 54-year-old teacher and a seven-year-old student, who remains in serious but stable condition.

Bend Police Chief Mike Krantz praised the individuals who showed courage and intervened, stating, "To the people who showed courage in the face of such violence, and intervened to prevent this tragedy from being any worse, we owe you a debt of gratitude." He noted that the teacher, who was unharmed, likely prevented further bloodshed.

Authorities executed a search warrant at the suspect's home and are investigating how he acquired the firearm and his precise movements leading up to the attack. A motive for the shooting remains unclear.

The suspect was armed with approximately 44 additional rounds of shotgun ammunition when stopped. He fired an estimated 15 rounds inside the classroom.
