Officials say a lone gunman armed with a rifle killed one student and injured a teacher at an Oregon school before the shooter was found dead.
Troutdale Police Chief Scott Anderson said Tuesday authorities have tentatively identified the gunman, but aren't ready at this point to release the name.
They are in the process of notifying the family of the gunman and student who was killed.
Anderson said the teacher suffered non-life threatening injures and was treated at the scene.
During the evacuation, another unrelated gun was found and one person was taken into custody.
The Multnomah County sheriff's office said there were reports of shots fired about 8 a.m. Tuesday at Reynolds High School in Troutdale.
Students were evacuated from the school, hands on their heads, to be reunited with their parents in a supermarket parking lot.
Dozens of law enforcement agencies and emergency responders remain on the scene.
About 2,800 students attend the school.
Troutdale is about 15 miles east of Portland.
