(CNN) -- The teenage gunman who opened fire in a high school cafeteria in Washington state last week may have had more victims had it not been for the bold actions of a young teacher. Witnesses say Jaylen Fryberg, a popular freshman, shot and killed a female student and wounded four others in the crowded lunchroom at Marysville-Pilchuck High School on Friday, about 34 miles north of Seattle. Megan Silberberger, a teacher, was in a nearby office when she heard the shots, said Randy Davis, president of the Marysville Education Association. "She ran into the cafeteria and saw students down," said Davis. Silberberger also saw a gunman.
