Griffin John II, the 16-year-old who opened fire in a special‑needs classroom at Silver Rail Elementary School in Bend, Oregon, had been the victim of assaults in recent years and told family members he was being bullied at school, according to police records released as investigators continue to probe the Oct. 15 attack that left three children and a teacher dead and two others wounded.

Police records detail prior violence and family turmoil

Records obtained by news outlets and summarized by law enforcement show that John was assaulted at least twice in recent years, including an incident at age 11 when a friend of his sister allegedly struck him at home, chipping a tooth. In a 2022 report, his mother, Shauntai Nickerson, told police the friend "slapped John across the face, causing him to chip a tooth," and that the friend also "punched John in the back of the head," according to the report.

"had special needs," and the officer wrote that it appeared he had a cognitive disability, given his "non verbal speech communication and speech patterns."

Police noted the teenager told his sister he had been bullied at school. The responding officer observed a small chip on one of John’s lower front teeth and recorded the boy’s account that the friend had asked if he wanted to fight before striking him and then punching him "4 to 6 times" in the back of the head. The report also described John’s speech and communication patterns as nonverbal and said the officer believed he "likely had a cognitive disability."

Attack and immediate aftermath

On Oct. 15, John opened fire in a classroom serving students with special needs. The attack killed three children and a teacher and wounded two other people before John was shot and killed by a man who has two daughters at the school. Authorities continue to investigate the shooter’s background and any possible motive, and many details remain under review.

Court and police documents previously obtained by media outlets portray a troubled home environment, including encounters between his parents and law enforcement as well as financial instability. Those records, along with the assault reports, give a partial picture of a youth who experienced violence at a young age and, according to family accounts recorded by police, struggled with bullying and communication challenges.

Questions about school safety and supports for vulnerable students

The attack has intensified scrutiny of security at schools, mental health and special‑education supports, and how incidents at home and at school are tracked and addressed. Officials and community leaders in Bend and beyond face pressure to explain what protections were in place at the campus and how warnings about the shooter’s prior experiences of victimization were, or were not, acted upon.

  • Victimization history: Records show assaults against John, including the alleged 2022 incident that left a chipped tooth.
  • Bullying reports: John told his sister he was being bullied at school, according to police records.
  • Possible disability: An officer documented nonverbal speech patterns and noted the boy likely had a cognitive disability.

Law enforcement has not released a full chronology of all contacts with the teenage suspect, and investigators caution that much remains unknown about his motives and whether other warning signs were missed. The presence of a shooter in a classroom for students with special needs has underscored concerns among advocates about the safety of vulnerable children and the adequacy of staffing and security measures in such settings.

Community response and next steps

Community members in Bend are grieving and seeking answers. Officials have said they are continuing their investigation, which includes reviewing court and police records and interviewing family members and witnesses. Any potential link between the prior assaults, reports of bullying and the deadly attack remains a central focus of the inquiry.

As officials continue to gather evidence, policymakers and educators will be watching whether the investigation leads to changes in how threats and past victimization among youths are assessed and addressed in schools, particularly in programs serving students with special needs.

Reporting note: Details in this report are drawn from police and court records previously obtained by news organizations and summarized by law enforcement; officials have said the probe is ongoing and many aspects of the case remain under investigation.
