A student opened fire in a high school cafeteria on October 24, in a shooting that killed four students, including the gunman.
The shooting at Marysville-Pilchuck High School, outside of Seattle, happened during the lunch period. Witnesses described the shooter walking in with a blank stare before opening fire.
"Just all of a sudden I see him stand up, pull something out of his pocket," Austin Taylor, who had just finished lunch, told NBC affiliate KING.
Taylor said he heard five pops, then saw three kids fall from the table.
The shooting is at least the 11th planned mass shooting at a school since the Sandy Hook massacre in December 2012, when Adam Lanza shot and killed 20 first-grade students and six adult staff members at the elementary school in Newtown, Connecticut, before killing himself. Here's a look at the ten other major incidents.
