Kaitlin Holt saved the life of a student during a school shooting thanks to a gunshot wound kit she had in her office. While she hasn’t taught for long, Holt reacted quickly and decisively, which saved the lives of many students. She was able to save this girl’s life, but two were taken during the senseless shooting.

Last Thursday, a young man opened fire at 7:30 a.m. in the Saugus High School in Santa Clarita, California. The entire incident left two students dead, three critically wounded, and many students and staff traumatized. After doing immense damage, the shooter turned the gun on himself and took his own life. Parents who were reunited with their children after authorities dealt with the situation were in tears, as they were relieved their children are alive.

Holt was teaching a music class when the shooting began. At first, they didn’t hear the gunshots because they were all listening to a recording of their singing. Suddenly, other students burst into the classroom for shelter, and everyone soon became aware of the situation. Holt rushed all the students in and wheeled the grand piano in front of the door. She guided dozens of students into the office with a locked door, and they all quietly sat on the floor—with muffled crying, silent texting, and quiet trembling. One student was able to quietly call the police while the rest tried to stay calm.

One of the students in the room, however, had been shot before she reached safety. There was a gunshot wound in her torso, and she had another on her shoulder. Holt only had one gunshot wound kit in her office, so she chose to deal with the more life-threatening wound in the torso. A brave student helped her out and applied pressure to the shoulder wound while she tended to the girl’s torso.

Thankfully, authorities arrived and handled the situation. Unfortunately, a 15-year-old girl and a 14-year-old boy were lost during the shooting. The school will hold a vigil for the lovely souls that were taken away from the world at that moment. Holt’s quick thinking and ability to remain calm saved a student’s life. While it’s depressing that schools now even need it, she highlights how important it is to have gunshot wound kids readily available at all times.
