Berhow's motive for the attack remains unclear, sheriff's spokesman Edmo Luna said Friday night, one day after the evacuation of Saugus High students in the first fatal shoot-out on the US campus. County sheriff Alex Villanueva said the shooter seemed to have fired arbitrarily but was "very familiar with firing the weapon" and had not committed any "spontaneous act".
It was at least the seventh shootout that, according to a Washington Post analysis ̵
1; a well-known tragedy, as data shows that since the 1999 Columbine High massacre, more than 230,000 children have suffered gun violence at their schools.
Two minutes after an emergency call, local representatives were on the ground. On Thursday at 7:38, the authorities reported the shooting on the Saugus High. They found the shooter in black clothes among six students with gunshot wounds in the quad area of the school. A seventh person was treated for uncritical injuries, according to officials.
The sheriff's office identified one of Berhow's classmates killed on Thursday as 15-year-old Gracie Muehlberger: one student admitted to a hospital was released, and two others are not expected to leave until this weekend.
The authorities said they had found a 45 caliber semi-automatic pistol on-site and were still working to prosecute the gun on Friday with the help of the Federal Office for Alcohol, Tobacco, Firearms and Explosives.
Officers On Friday, they said they had interviewed more than 40 people, but had not yet found a letter from Berhow that could provide insight into his pre-attack considerations.
During further investigations, the sites at the William S. Hart Union High School District were closed Friday as a mark of respect for the victims.
The Saugus High students did everything they learned in an active shooting practice just a few weeks before Thursday's "pointless violence," Villanueva told reporters. They barricaded doors, covered windows, and held themselves in their place, he said, in a "well-done job" that he hopes never to repeat.
"It's a tough day here in Santa Clarita," the sheriff said, urging people to "keep their kids a little bit tighter."
Mayor Marsha McLean reiterated Villanueva, saying the shooting had shaken a close community.
"While I talk to our residents, we all feel what happened," she said.
