Sheriff’s officials declined to publicly identify the suspect because he is a minor. But two law enforcements sources identified him to CNN as Nathaniel Berhow.
Investigators had not discovered a motive for the attack as of Thursday afternoon, Los Angeles County Sheriff’s Capt. Kent Wegener said at a press conference. Detectives served a search warrant on a residence believed to be the suspect’s home, Wegener said. He said there was no history at that address indicative of problems prior to the shooting.
Another sheriff’s official, Tim Murakami, tweeted that rumors that the suspect may have posted threats on social media would be investigated.
“I literally thought he was a normal kid,” said Brizio DelRosario, 16, who ran with Berhow on the Junior Varsity Cross Country team. “We would run together sometimes. The last time I saw him was at a race about 2 weeks ago, he was totally normal. I started next to him and he wished me luck.”
“He wasn’t a quiet or a weird kid,” DelRosario said.
Another teammate, who asked that his name not be used, said the student, whom they called Nathan, was in a group of about 7 or 8 friends who all ran track at Saugus High and went to parties together. He said he knew Nathan “very well” and that he is “the sweetest kid you’ll ever meet.”
He said he first met Nathan when Nathan was a freshman and he was a sophomore. They became close friends shortly after Nathan’s father passed away in 2017.
“Nathan is shy,” the friend said. “I saw Nathan yesterday, we went on a hill run with maybe four guys. He was totally normal, cracking jokes as usual.”
The friend explained that the cross-country team is on off season right now but that they’re required to run a mile a day regardless, Nathan had actually suggested the hill run which meant running up a hill behind the Saugus campus and back down through a neighborhood.
On Thursday, the friend went to school for his first period economics class on the upper campus.
“During class we could see kids running and dropping their backpacks. At first I thought they were running because they were late for second period but then I realized we were still in the middle of first period,” he said. “Someone came in and was clearly distressed and said there was a shooter.”
“We turned off the lights and barricaded the door,” the student said. “I grabbed scissors just in case I had to fight…” Two of the suspect’s five victims were fatally wounded.
The student in the economics class said he had once gone to a shooting range with Nathan. He said he knew Nathan had access to guns and that he grew up around them but it was never a concern because he knew how to handle them and was responsible.
He also said Nathan’s mom is “the sweetest woman I’ve ever met” saying that whenever she would drop off or pick up Nathan from practice, she would make it a point to say something kind to the guys.
Kelly Axen said she has lived next to Berhow and his family for the past 6 and a half years. She said in years past she would pick Nathan up from school, help him with homework and even help to cook his meals.
She said Berhow appeared to be struggling since the death of his father in 2017 and leaned heavily on his mother and sister for support. His parents divorced in 2016.
Axen said neither she nor her husband, who has known the family even longer, saw any warning signs for Thursday’s shooting.
