UPDATE: Police says shooter at high school near Seattle was student, is dead
(CNN) - The gunman who opened fire Friday morning at Marysville-Pilchuck High School, just north of Seattle, is dead, a police spokesman said.
Authorities "are confident that there is only one single shooter," Marysville police spokesman Robert Lamoureux told reporters.
He did not offer any details about possible injuries, but said there was only one fatality.
Police and witnesses said that up to six people were injured.
Authorities first learned about the shooting after getting a 911 phone call around 10:30 a.m. (1:30 p.m. ET) from someone inside the school, Lamoureux said.
"The Marysville-Pilchuck High School is currently in lockdown due to an emergency situation," the school district said in a statement.
"Police and emergency services have responded. The Marysville School District lock down procedures will remain in effect at Pilchuck until further notice from law enforcement."
A student locked down inside a classroom told CNN by phone that the shooting began in the cafeteria.
The student, whose name is being withheld, said when the shooting began students initially thought it was a fire drill until teachers told everyone to run into classrooms because there was was a shooting.
At least one person has been airlifted, according to the student. She believes multiple people have been shot.
The student said she was hiding in a classroom with other students, all of whom are unharmed.
Medeana Johnson, mother of a boy who is a junior at the school, told KIRO that her son said a boy opened fire near the cafeteria. She said her son told her he was supposed to be in the cafeteria but stopped to chat with someone and so didn't go in.
CNN affiliate KIRO-TV in Seattle showed police cars and ambulances outside the school. Aerial shots showed students running out of the buildings, many with their arms up.
