Charges and the proposed adult trial
The teenager, whose name has not been released because of his age, is charged in connection with the Sept. 8 incident at Benson Polytechnic High School. The counts include 10 allegations of attempted aggravated murder, one count each of attempted first-degree murder and attempted second-degree murder, and first- and second-degree domestic terrorism charges.
Additional allegations include unlawfully manufacturing and possessing a destructive device, possessing a weapon in a public building, unlawfully using a weapon and recklessly endangering another person. Multnomah County District Attorney Nathan Vasquez said on Oct. 2 that his office would seek to transfer the case from juvenile court to adult court, citing the safety of students and staff.
“Safety in our schools is not something that can be negotiated.”
What happened inside the cafeteria
The incident unfolded shortly before 8:30 a.m., while numerous students and employees were near the teenager in the school cafeteria. Authorities said he had brought chemicals from home and mixed them inside the Portland school, creating a dangerous release that affected people in the building.
Teachers and administrators moved students away while the school nurse treated the teenager. First responders then transported him to a hospital in critical condition, although he survived. More than 100 students and staff members were assessed after the evacuation, and at least seven people required medical care.
Chemical evidence and the ongoing investigation
Investigators said initial testing indicated the presence of hydrogen sulfide, a toxic gas. Jim DeFrain, who supervises the investigation and the Metropolitan Explosive Disposal Unit, said an Oregon National Guard team reached the same preliminary assessment.
Samples were sent to an FBI laboratory for additional testing, and results were still pending during the Oct. 2 briefing. Investigators were also examining electronic equipment seized during searches. Authorities have not said that the laboratory review has produced a final conclusion.
The investigation remains active. Vasquez said prosecutors would consider charges against anyone else found to have criminally participated in the incident.
Earlier concerns and school safety issues
Portland police said investigators found what they described as concerning behavior and statements before the chemical release. Mike Benner, a police public information manager, said the reported interests included hazardous chemicals, explosives and violence.
Authorities have not publicly detailed how those earlier observations relate to the charged conduct or whether they led to action before Sept. 8. The immediate response involved moving students away from the area, providing medical treatment and evacuating the school population. Franz Schoening, assistant chief of investigations, said the first moments were critical in limiting additional harm.
“Those first few moments were critical in preventing further harm and lives being lost.”
Defense response and next legal steps
The teenager’s attorneys denied the allegations and said he was receiving treatment at an inpatient mental health facility. Because the defendant is 15, prosecutors must seek a court decision before the case can proceed in adult court.
Vasquez also criticized Oregon’s juvenile system, saying its oversight ends at age 25 even when a person may continue to pose a public safety risk. He argued that the legal system should consider the nature of the alleged conduct and the community’s future safety. The court will determine how the case proceeds, while investigators continue reviewing physical, laboratory and electronic evidence.
