Students and parents weep and hold each other as they reunite after a 16-year-old student dressed in black opened fire on his classmates at a northern Los Angeles school Thursday, Nov. 14, 2019.
The student, dressed in all black and armed with a weapon, opened fire at Saugus High School as the day as classes began.
One female student and a 14-year-old boy among several injured had died, officials said. Others remained in critical condition.
"It's one of my worst nightmares as a sheriff," Los Angeles County Sheriff Alex Villanueva said.
