The shooter who police said opened fire at YouTube’s headquarters in San Bruno, California, Tuesday — wounding three people before killing herself — has been identified as 39-year-old San Diego woman Nasim Najafi Aghdam.
San Bruno police said Aghdam died from a gunshot wound believed to be self-inflicted on the scene. She is believed to be the sole perpetrator of the shooting.
Authorities said there is no evidence that Aghdam knew or specifically targeted the victims.
San Bruno Police Chief Ed Barberini said during a Wednesday appearance on Good Morning America that Aghdam “had a problem with the policies or practices that YouTube had employed. That was her opinion.”
He added, “We do understand that point. We don’t understand exactly or specifically what those concerns were and we have investigators who are now taking numerous steps to finalize that and pinpoint exactly what her concerns were to clearly identify the motive. We have a pretty good idea, but we’d like to get some more information before we can definitively say exactly what that motive was.”

Barberini confirmed on GMA that Aghdam was reported missing by her family on March 31 and located Tuesday morning about 30 miles from the site of the shooting.
Of the weapon, which the police chief described as a semi-automatic handgun to GMA, Barberini said there “was nothing to suggest that it was not legally obtained.”
Barberini told reporters on Tuesday that police first responded to the corporate campus, which Time reported has more than 1,100 employees, after “numerous” 911 calls around 12:45 p.m. local time.
He initially told reporters four people were injured, but later said three people were wounded by gunfire, according to the Associated Press. A 32-year-old woman was in serious condition, while a 27-year-old woman was in fair condition, as of Tuesday. The third victim, a 36-year-old man was in critical condition on Tuesday, according to USA Today.
One other person was taken to the hospital for an ankle injury.
Fed Krysko, 21, was on his way to the mall when he came across the shooting where “tons of people” were stampeding to get out.
He told PEOPLE the scene was pure “craziness.”
“I got there right after it was happening. I was driving down Cherry Avenue, the street YouTube is on, and it is swarming with police officers, so I pulled over and I get there just as people are being evacuated with their hands up,” he said.
Krysko said “at least 100 people” ran out of the building. “They were scared and in shock. They were just running with their hands up. It was a state of panic where you don’t know what is going on yet.”
A woman who was near YouTube’s offices during the shooting described a tumultuous aftermath as authorities swarmed the area.
“There were a lot of people in the streets watching everything going on, but they cleared the streets,” the woman, a 40-year-old who lives in San Bruno and who asked not to be identified by name, told PEOPLE.
“We were scared,” the woman said. “We thought somebody was coming into the store where we were.”
The woman said that in a supermarket, around the corner from YouTube, they quickly encountered people leaving the scene. “At the beginning a man came in with scratches on his face,” she said. “We thought he was the shooter but he wasn’t — he said he fell when he was running away.”
