Los Angeles County authorities announced at an afternoon press conference that the shooter, a 16-year-old student at Saugus High School in Santa Clarita, removed a .45 caliber semi-automatic pistol from his backpack and opened fire on the quad, shooting five students before shooting himself in the head.

The deceased victims are a 16-year-old girl and a 14-year-old boy.

The shooter — whose birthday is today — is in grave condition after his self-inflicted gunshot wound. His gun was recovered at the scene and had no more bullets in it, authorities said.

Deputy Grace Medrano described the suspect to PEOPLE as an Asian male who was wearing a black hat and blue jeans.

“It’s a sad day in Saugus,” L.A. County Sheriff Alex Villanueva said at the press conference.
