According to NBC News, one student said a number of her friends had been wounded in the attack, which occurred right after school officials opened the doors for the day. She said upon entering the school, a stampede of students were rushing at her and screaming that someone was stabbing people.

The president and CEO of one of the hospitals where some victims were being treated said one of the victims could have saved one of the others’ lives. She reportedly applied pressure to the wound, which enabled the person to hold on long enough for emergency workers to take the victim to the hospital.
