Incident Overview
On September 8, 2026, a 15-year-old student at Benson Polytechnic High School mixed hazardous chemicals in the school cafeteria, creating a cloud of toxic gas that caused the teen to lose consciousness and be taken to a hospital in critical condition. Staff and first responders evacuated the building and treated those exposed. More than 100 students and staff were evaluated; at least seven required medical care. Police identified hydrogen sulfide and hydrogen cyanide as the most dangerous components, and samples were sent to an FBI laboratory for further analysis.
Legal Charges
Multnomah County District Attorney Nathan Vasquez filed 19 criminal counts, including:
- Twelve counts of attempted murder (aggravated and first-degree)
- First- and second-degree domestic terrorism

Vasquez announced that the office will seek to move the case from juvenile to adult court, arguing that the alleged conduct poses a continuing threat to community safety.
