Police in Washington state say one person was killed in a high school shooting in addition to the lone student gunman, who reportedly died of a self-inflicted gunshot at Marysville-Pilchuck High School in Marysville, which is located some 35 miles north of Seattle and attended by at least 2,500 students.
Three other victims remain in critical condition after the shooting, according to Providence Everett medical center spokeswoman Heidi Amrine. One victim considered in stable condition was taken to Harborview Medical Center.
Meanwhile, Marysville Police Commander Robb Lamoureux said Friday that police are continuing to search Marysville-Pilchuck High School.
Students and staff members walked out of the school after police and ambulance crews surrounded the large campus. Police went room by room, searching the school to make sure it was safe on Friday afternoon.
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."
The school district released a statement earlier saying the school was "in lock down due to an emergency situation." Later, a crowd of parents waited in the parking lot outside a nearby church where they were being reunited with their children.
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.
Ayn Dietrich, an FBI spokeswoman in Seattle, told The Associated Press the agency had personnel on their way to the scene to help authorities with the investigation.
The latest school shooting in the region happened at Seattle Pacific University, where a gunman killed one student and wounded two others on June 5.
According to the group Everytown for Gun Safety, this is the 87th school shooting since Adam Lanza killed 26 at Sandy Hook Elementary School at the end of 2012.
