A Bend, Oregon, parent who fatally shot a gunman at Silver Rail Elementary School last week described the attack in an interview with Oregon Public Broadcasting that aired Friday, CBS News and the BBC reported^2,18.

Kaylub Giamanco, 36, said he was driving home for lunch when he saw a person with a long gun, retrieved a handgun from his truck and called 911¹⁸. He said he told the dispatcher he had to go in^2,18.

He said he followed the attacker, crawled through a broken window and found a teacher struggling with the gunman, then fired, including additional shots when the attacker reached for a weapon^2,18. Police identified the gunman as 16-year-old Griffin J. John II, a former student; a motive was not established in the reports reviewed².

Police said the attack killed three children, ages 5, 8 and 11, and teacher Megan Lambert, 25, and wounded a 7-year-old and teacher Becky Drury, 54^2,18. Bend Police Chief Mike Krantz said the teacher who fought the gunman almost certainly prevented more bloodshed^2,18. Gov. Tina Kotek praised Giamanco's intervention¹⁸.

Giamanco said he wants to apologize to families of children who died and that he replays the day at night^2,18. He is not charged in the reporting reviewed; investigators have described his actions as stopping the attack¹⁸.
