Two students have been shot at Graham-Kapowsin High School in Graham, Wash., the Pierce County Sheriff's Department confirms.

The shooting happened about 2:30 p.m. just off school grounds. Pierce County deputies say the victims ran back onto the Graham-Kapowsin campus after being shot. The shooting may be gang related.

Officials say one student was found in the parking lot by the school football field; the other student was found in a locker room. The two students were transported to Tacoma General Hospital; the victims' conditions are unknown.

The suspects are described as multiple black males, who fled the scene in a green vehicle, possibly a Chevy Impala.

Deputies are actively sweeping the school grounds. At this point, officials say it appears the shooters are not on campus. All remaining students on campus are secured and considered safe as deputies conduct their security sweep.

Graham-Kapowsin High School is located at 108th Ave E & Eustis Hunt Road E. The shots were reportedly fired on the Eustis Hunt Road side of the campus.
