SANTA CLARITA, Calif. -- Two people were killed and several others were wounded in a shooting at Saugus High School in Santa Clarita Thursday morning, authorities said.
The shooting was reported at the campus, north of Los Angeles, around 7:30 a.m. Officials said the suspected shooter, a 16-year-old boy who attended the school, was in custody and being treated at the hospital as of 11:30 a.m.
Authorities said surveillance video "clearly shows" the young man pull a handgun out of his backpack in a busy school quad, shoot five people, then shoot himself in the head. All of the victims were students on campus, officials said.
Two gunshot victims died at the hospital, a 16-year-old girl and a 14-year-old boy. Three other victims were still being treated at the hospital as of noon: a 14-year-old girl, a 15-year-old girl and a 14-year-old boy.
The victim was also taken to the hospital from campus, but that wasn't immediately clear to authorities, who were still searching for a gunman for several hours.
Investigators found a .45-caliber, semi-automatic handgun in the quad.
Officers could be seen canvassing the surrounding neighborhood, including a brushy area, drainage ditch and empty backyard pool. Santa Clarita County and Los Angeles County sheriff's officials warned residents to lock their doors and stay inside.
Authorities surrounded the suspect's home with a SWAT team around 9:15 a.m. Investigators said they searched the house for any other victims, but found none. The boy's girlfriend and mother were cooperating with police.
A short time later, Los Angeles County Sheriff's Department announced the gunman was in custody at the hospital.
There were several elementary schools near the high school campus, and officials said all schools in the William S. Hart School District were locked down as a precaution. Parents were told to head to Central Park, not far from the school on Bouquet Canyon Road, to reunite with their kids.
Saugus High is a public school for grades nine through 12, with about 2,400 kids in attendance.
Students were allowed to leave campus shortly before 9:30 a.m. and could be seen streaming out of school in lines, but they weren't immediately allowed to reunite with parents.
LASD said investigators had to interview each student before they could be released. "We need to conduct a thorough investigation," Undersheriff Tim Murakami explained. "We apologize for the wait."
San Diego Police Department said they were aware of the shooting, and though it was considered "isolated," they had increased patrols at local schools as a precaution:
