There was no immediate word on the students' conditions, but both were sent to local hospitals.
Police report that the shooting didn't happen on the school grounds but that the victims ran onto the school campus after being shot.
Troyer said they believe the two victims were students of the high school, but the shooters were not.
Police are responding to reports that two students were shot at Graham-Kapowsin High School in Washington.
