SAN BRUNO, Calif. — At least three people were wounded and the suspected shooter, a woman, was found dead on the campus of the YouTube headquarters, San Bruno, California, Police Chief Ed Barberini told reporters Tuesday.
The woman was identified Tuesday night as Nasim Aghdam, two law enforcement sources tell CNN.
The chief said Aghdam had an apparent self-inflicted gunshot wound.
Aghdam is believed to have known at least one of the victims, two law enforcement officials told CNN.
A spokesman for Zuckerberg San Francisco General Hospital, a level 1 trauma center, said the facility received three patients. One 36-year-old man was in critical condition, one 32-year-old woman was in serious condition and one 27-year-old woman was in fair condition.
One witness inside a cafe near the shooting said the gunfire didn’t immediately register with him.
“It was a surprise, because you don’t really expect something like that,” the man told CNN affilaite KPIX. “I heard some pops, I obviously thought it was balloons, but then I thought that doesn’t make sense, not today. Then I heard more shots and that’s when everyone started scrambling for the door.”
Vadim Lavrusik, a YouTube product employee, said he and others hid.
“Heard shots and saw people running while at my desk. Now barricaded inside a room with coworkers,” he tweeted.
Not long after the first tweet he wrote: “Safe. Got evacuated it. Outside now.”
Another YouTube employee said during the shooting people were trying to get out of the building “as fast as they could.”
She said she was on a conference call and a colleague, who heard shots, told her at least one person was shot on the patio where people eat.
“We were all suddenly aware of a lot of noises, of sounds, people running outside of the room where she was. And people screaming,” said the employee, who was in a building down the street.
” ‘I have to get out of here,’ ” the woman said her colleague said.
A witness told CNN affiliate KRON he heard two or three shots and later about 10 shots. He was at a Carl’s Jr. fast-food restaurant across the street from an end of the YouTube building where there are tables with umbrellas on a patio.
A woman ran over to the Carl’s Jr. with a leg wound, he said. People at the fast-food restaurant tried to use napkins to stop the bleeding.
Overhead video from KGO showed a heavy police presence outside the YouTube building. A crowd of people gathered outside the building and, one by one, were frisked and patted down by officers. Several roadways near the building were closed to traffic.
YouTube, which was founded in February 2005, quickly became the most well-known of several online video sites. In 2006 Google said it was purchasing YouTube for $1.65 billion in stock.
