A gunman killed a student at an Oregon high school and later was "confirmed deceased," authorities said.
SWAT teams descended on Reynolds High School after receiving a report of a shooting, Troutdale Police Chief Scott Anderson said. He said a room-by-room search was underway at the school outside Portland.
"This is a very tragic day, one that I had hoped would never ever be part of my experience," Schools Superintendent Linda Florence said. "We feel very sorry for our parents."
She said the students were "absolutely wonderful" at evacuating the building. Teary reunions were underway as parents were reunited with their kids at a parking lot near the school.
Sue Strickland, police records specialist for the Troutdale police, told USA TODAY the shooter was a male teen. She could not confirm whether he was a student at the school.
"We are still checking the building," Strickland said. "We have about 40-50 units out there. We have several SWAT teams in the building right now and they are checking to make sure that they've got things under control. A semi-automatic weapon was used."
