TROUTDALE, Ore. (USA TODAY) -- Tragedy struck an Oregon high school Tuesday when a teen with a rifle killed a student and wounded a teacher at the start of the second-to-last day of the year.
The gunman was found dead a short time later in a bathroom stall, apparently from a self-inflicted wound, police said.
SWAT teams descended on Reynolds High School after receiving a report of a shooting, Troutdale Police Chief Scott Anderson said. The school, the state's second-largest high school with 2,800 students, was locked down and a room-by-room search was conducted.
Anderson said the identities of the gunman and his victim would be released after their families were notified.
"There will be several days of healing and ongoing attention given to the students and the staff," the police chief said.
Anderson confirmed a KGW-TV report that more than one person had a gun at the school. Anderson said the second person was taken into custody, but that the person was not believed to have been involved in the shooting.
School Superintendent Linda Florence said counseling was being made available to the school community.
"This is a very tragic day, one that I had hoped would never ever be part of my experience," Florence said. "We feel very sorry for our parents."
She said the students were "absolutely wonderful" at evacuating the building. The students exited the building, hands over their heads, and gathered in a nearby parking lot for teary reunions with parents.
Freshman Morgan Rose, 15, said she hunkered down in a locker room with another student and two teachers.
"It was scary in the moment. Now knowing everything's OK I'm better," she said.
Reynolds track coach Todd Rispler told KGW-TV he was grazed on the hip but was not seriously hurt. He was treated at the scene and released.
Freshman Daniel DeLong, 15, said he saw a physical education teacher at the school with a bloodied shirt.
"I'm a little shaken up," DeLong said. "I'm just worried."
He said he was texting friends to make sure they were all OK.
"It just, like, happened so fast, you know?" he said.
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. She said multiple police departments responded, including several SWAT teams.
Troutdale Mayor Doug Daoud lauded police for their quick response.
"This has been a very unsettling day for our precious city," Daoust said. "My heart goes out to all the families."
Oregon Gov. John Kitzhaber issued a statement of condolence for the school community.
"My heart is heavy after learning of this morning's tragic events at Reynolds High School," the statement said. "Today Oregon hurts as we try to make sense of a senseless act of violence. Please keep students, staff, the extended Reynolds community and first responders in your thoughts and prayers."
Agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives are heading to Reynolds High School to assist in the investigation, the ATF said on its Twitter feed.
The school, which includes grades 9 to 12, has more than 2,800 students. Troutdale, an eastern suburb of Portland, is home to about 16,000 people.
