A 13-year-old student told the Reno Gazette-Journal that he saw a student fire a shot at a teacher.
"The student was pointing a gun at the teacher after the teacher told him to put it down, and the student fired a shot at the teacher, and the teacher fell, and everybody ran away," the student said.
