Los Angeles (CNN) A male student opened fire on classmates Thursday morning at a Southern California high school, killing a 16-year-old girl and a 14-year-old boy, Los Angeles County Sheriff Alex Villanueva told reporters.
Three other students were wounded and hospitalized, he said.
The suspected shooter, who turned 16 on Thursday, was hospitalized with a gunshot wound. Officials said he is in grave condition.
The shooting at Saugus High School in Santa Clarita began before classes started, officials said, sending some students streaming out of the building as others hid.
Video obtained at the scene clearly shows the suspect taking a .45-caliber pistol from a backpack before shooting five people and then himself, Capt. Kent Wegener of the Los Angeles County Sheriff’s Department told reporters.
Authorities are working to obtain any other video from campus and cell phone video from students.
Emergency workers took several people out of the school on gurneys, and large groups of people walked out single-file with armed escorts, aerial footage from CNN affiliates shows.
Officials shepherded students to nearby Central Park, where parents were told to meet them.
The shooting happened about 20 minutes before the start of school, according to Hannah de Caussin, whose daughter attends Saugus.
