A teacher fought the teenage shooter and a parent shot him dead, police say on Friday, a day after four people were killed.

The 16-year-old who killed three children and a teacher at an elementary school in the US state of Oregon was a former special-needs student at the school, police and school officials have said.

Bend Police Chief Mike Krantz identified the attacker on Friday, a day after the shooting at Silver Rail Elementary School, as Griffin J. John II.

He said the teenager attacked a classroom of special-needs students, where all the victims were shot.

Steven Cook, superintendent of Bend-La Pine Schools, said John was not enrolled in the local public school system at the time.

“That classroom was a special needs classroom, and the suspect was a special needs student in that school,” Cook told a news conference.

Krantz said John shot his way through locked doors with a 12-gauge shotgun, firing as many as 15 shots, and had about 44 rounds left when he was killed. Police are still trying to determine how he obtained the gun.

Under Oregon law, a minor may possess a shotgun if provided by a parent or with a parent’s consent.

The shooter’s mother, Shauntai Nickerson, separately told reporters outside her apartment: “I’m so sorry, I wish I could have done something.”

A teacher threw her phone at the gunman, then tackled and fought him, likely saving lives, Krantz said, calling her actions “heroic”. She was not injured.

A 36-year-old father, Kaylub Giamanco, who has two children at the school, then followed the gunman inside and shot him dead minutes after the first 911 call.

US President Donald Trump called Giamanco a “great hero”. “It’s a terrible thing, but thank goodness for a man that had a gun and knew how to use it,” Trump said.

The children killed were aged five, eight and 11, and the teacher was Meghan Lambert, 25, police said.

A seven-year-old child and a 54-year-old teacher were taken to hospital in critical condition.

The shooting is the 28th mass killing in the US this year, according to a database by The Associated Press, USA Today and Northeastern University.

The Gun Violence Archive in the US has documented 369 mass shootings in 2026, defined as incidents in which four or more people are shot.

The Everytown for Gun Safety group has counted at least 100 incidents of gunfire on school grounds this year, with 34 deaths.
