UPDATE: Student gunman kills one, commits suicide in Washington
A lone student shooter killed himself Friday after opening fire at the Marysville Pilchuck High School, north of Seatle, killing another student.
Three other students have been hospitalised with gunshot injuries - all to the head.
Students and staff members were seen walking out of Marysville Pilchuck High School after police and ambulance crews surrounded the large campus of more than 2,000 students.
Police were going room by room, searching the school about 30 miles north of Seattle, to make sure it was safe.
"It is an active scene," Marysville Police Commander, Robb Lamoureux said.
"We do ask parents to please stay away."
Adam Holston, 14, a freshman, was just leaving the lunch room when the gunfire broke out.
"Everyone just started running," he told The Seattle Times.
"I could hear the gun shots and my heart was racing and we didn't know what was going on."
Buses pulled up periodically to drop off students evacuated from the school, with some running to hug their mothers or fathers.
Some parents were sent back to their cars to get their identifications before they could leave with their children.
The previous school shooting in the region happened at Seattle Pacific University, where a gunman killed one student and wounded two others on June 5.
