After the shooting, authorities engaged in an intensive search for the gunman, who was in critical condition after shooting himself in the head.

A teenage gunman opened fire at a Southern California high school Thursday morning, killing two students and wounding three others, before shooting himself in the head, officials said.

The suspect, whom authorities described as an Asian male who turned 16 on Thursday, was in critical condition at a hospital, the Los Angeles County Sheriff’s Department said Thursday night. Surveillance video showed the shooter pull a gun from his backpack in the quad area of Saugus High School, shoot five people and then shoot himself, it said.

“Within approximately 16 seconds, it was over,” sheriff’s Capt. Kent Wegener said.

Multiple law enforcement sources told NBC News that the suspect was identified as Nathaniel Tennosuke Berhow.

A 16-year-old girl and a 14-year-old boy died, authorities said. Three other students — two girls, 14 and 15, and a 14-year-old boy — were also shot before classes began, officials said. They were listed as stable on Thursday night.

All of the victims and the suspect attended Saugus.

“I hate to have Saugus be added to the names of Columbine, Parkland, Sandy Hook, but it’s a reality that affects us all throughout the nation, something we’re going to have to deal with,” Sheriff Alex Villanueva said at a news conference after finding out that the second student had died.
