A high school outside of Seattle, Washington was locked-down Friday after a student opened fire.

Emergency calls were made late Friday morning local time at around 10:45 a.m. by individuals reporting a suspected shooting at Marysville-Pilchuck High School. Around 75 minutes later, Marysville Police Commander Robert Lamoureux told reporters: "We are confirming that there is one deceased, and that is the shooter."

According to preliminary, unconfirmed reports, as many as six people were shot at the school, with CBS News claiming first that at least three people have been administered to a local hospital with gunshot wounds, then reporting later that two victims had died, citing law enforcement sources. KIRO, a local network, reported that at least three victims had been administered to a local hospital in critical condition around two hours after the shooting occurred.

"The Marysville-Pilchuck High School is currently in lock down due to an emergency situation, the school said. Police and emergency services have responded. The Marysville School District lock down procedures will remain in effect at Marysville Pilchuck until further notice from law enforcement. We will continue to forward communication in cooperation with law enforcement."

Marysville-Pilchuck is a large school with roughly 2,500 students. The shooter was reportedly in the cafeteria, according from tweets sent by individuals purported to have been at the school at the time. The gunman in the lunchroom opened fire on several students, one mother reported her child saying to local station KOMO News.
