The school board voted to suspend four teachers, three administrators and three students after a student shot himself and two other students.
The school’s policy is that guns are banned, and that only students who are “mentally stable” can bring guns into the building.
A spokesperson for the Texas Board of Education says the board “has been in touch with all concerned parents, students and staff about this situation.”
The students who died were taken to the hospital and are expected to survive, the school says.
