Oregon school shooter Griffin John II, 16, deliberately targeted his old special needs classroom massacre that killed four

A teenager mass murderer was so determined to gun down little kids at his old elementary school that even being shot at didn't stop him.

Griffin John II, 16, killed three children aged five, eight, and 11, and their 25-year-old teacher at Silver Rail Elementary School in Bend, Oregon, on Thursday afternoon.

He also critically wounded a 54-year-old teacher and shot a seven-year-old child who uses a wheelchair in the face, both of whom are still in hospital. 

The twisted teen fired as many as 15 shots during his rampage and had 44 left when he was finally shot dead, police said.

John fired on everyone inside a special education class, where he himself was a student when he attended the school as a young child.

He was so hell-bent on targeting his former class that when he was fired upon when he tried to enter the front door, he ran around to the back entrance, police said.

John - who was not enrolled in a Bend public school at the time - traveled to Silver Rail Elementary on foot. 

He first threw the Maverick 88 12-gauge pump-action shotgun over the fence before jumping over - but found himself blocked from entering.

John was fired upon by hero dad Kalub Giamanco - who would later shoot the teen dead - and blocked by another bystander's van that he riddled with bullets.

Instead of giving up, he ran to the back entrance and blasted his way through a 'safety vestibule' system designed to keep children at the school safe from school shooters.

The school resource officer was not at the school at the time of the shooting, authorities said. They said the officer oversees around six other buildings and was at a nearby school.

Police were unsure how John was able to get his ammunition, stating the investigation was still 'very active.' 

Five weeks before he went on his shooting rampage, the teenage mass killer stared at a camera with a murderous gaze.

John was gangly with a patchy mustache and goatee and looked sullen in a haunting photo posted by his mother Shauntai Nickerson last month.

Nickerson told a TV station in 2020 that she was pleased students were going back to the classroom as her son was struggling with distance learning during Covid lockdowns.

'I think it will be great for Griffin, because I am not certified teaching a special needs student,' she told KTVZ 21.

'And I think it will be great for my son to get the help that he needs from the skilled teachers that he needs to get it from.'

The future murderer was in the NEST (Nurturing Empathy Safety and Trust) program, which helped special education students 'experiencing intensive behavioral and social skills challenges'.

The first victim of the shooting was named as five-year-old Rhoam Summer. 

Summer's teacher has been identified as 25-year-old Meghan Lambert of Bend, while the other child victims will not be named at this time out of respect for the victims' families, Bend police said at a press conference on Friday. 

The family of Lambert, in a statement read by officials, said she grew up in Bend, graduated from Boise State University and had a passion for sports, especially volleyball, and was a local coach.

They said she was funny, opinionated, 'fought for the underdog' and 'those with special needs'

'Meg loved those children,' the family said.

John used his mother's shotgun to carry out the massacre, which police said was bought about the time of his 16th birthday.

Nickerson, 43, a medical aide at Touchmark Living Centers, has a long list of traffic violations and was charged with DUI at 1.37am on July 29, 2018, by local police in Bend.

She was also convicted of harassment in 2023 with a second charge of fourth-degree assault from the same incident dismissed.

Nickerson insisted to reporters who confronted her outside her home in Bend that her son was 'a good boy' and she would have stopped him if she could. 

John II's motive is unknown, but he attended the school as a child before moving on to the local high school. 

Police raided John II's family home on Thursday night, seizing computers and other electronic devices. Family was said to be cooperative.

John II was shot dead minutes after he began his rampage by Kalub Giamanco, 36, a dad of two children at the school who heard the gunshots as he drove home for his lunch break.

Giamanco's wife Kelsey and brother Kyle, along with several of his friends, confirmed he was the hero who intervened by running inside the school.

He holds a concealed carry permit and is friends with the family of the seven-year-old in the wheelchair who was wounded. 

Giamanco shot John II dead within moments of the massacre beginning just before 1pm on Thursday.
