A shooting at Silver Rail Elementary in Bend, Oregon, killed three special-needs pupils aged 5, 8 and 11 plus their 25-year-old teacher and wounded another child and staff member. The 16-year-old former student who carried out the attack used a pump shotgun his mother had purchased legally; state and federal rules already forbid minors from possessing firearms and designate the campus a gun-free zone.

Kaylub Giamanco, 36, a licensed concealed-carry holder and father of two children at the school, heard the first shots while driving past at lunch, ran inside and fatally shot the attacker within three minutes, before officers arrived. Governor Tina Kotek later said his intervention likely prevented more deaths. Several Democratic senators, including Ron Wyden, Chris Murphy and Mark Kelly, nevertheless called within hours or days for tighter national gun laws.
