SAN BRUNO: A woman opened fire at YouTube`s headquarters near San Francisco on Tuesday, wounding four people before taking her own life as employees of the Silicon Valley technology company fled into the surrounding streets, authorities said.
Police initially did not release any further information on the suspect or her motives for the shooting rampage at YouTube, a video sharing service owned by Alphabet Inc`s Google.
However, the law enforcement authorities later identified the suspect as Nasim Aghdam of Southern California, news agency AP reported.
MSNBC earlier said that police believe a woman in her 30s approached an outdoor patio and dining area on the campus around lunchtime and began to fire, before turning the gun on herself.
Senior law enforcement officials believe the motive behind the shooting stemmed from a domestic dispute. They had no known connection to terrorism, a US government security official told Reuters.
A YouTube product manager, Todd Sherman, described on Twitter hearing people running, first thinking it was an earthquake before he was told that a person had a gun.
"At that point, every new person I saw was a potential shooter. Someone else said that the person shot out the back doors and then shot themselves," Sherman said on Twitter.
"I looked down and saw blood drips on the floor and stairs. Peaked around for threats and then we headed downstairs and out the front," Sherman said.
The shooting was the latest in an epidemic of mass killings that have plagued the United States in recent years. Most recently, the massacre of 17 people at a Florida high school has led to calls for tighter restrictions on gun ownership.
In a recording of a 911 call posted online by the Los Angeles Times, a dispatcher can be heard saying: “Shooter. Another party said they spotted someone with a gun. The suspect came from the back patio ... Again we have a report of a subject with a gun. They heard seven or eight shots being fired."
Dozens of emergency vehicles quickly converged on the YouTube campus, and police could be seen on televised aerial video systematically frisking several employees leaving the area with their hands raised.
One of the victims, a 36-year-old man, was listed in critical condition at San Francisco General Hospital. A 32-year-old woman was listed in serious condition and a 27-year-old woman in fair condition. Authorities did not release names of the victims.
The three patients taken to San Francisco General Hospital were all awake, Dr. Andre Campbell, a trauma surgeon at the hospital, said at a news conference. All three people were victims of gunshot wounds, Campbell said, but none of them had undergone surgery. A fourth person was taken to a local hospital with an ankle injury from fleeing the scene.
Google said on Twitter that it was coordinating with local authorities. YouTube Chief Executive Susan Wojcicki declined to comment to reporters as she left the building.
President Donald Trump said on Twitter that he had been briefed on the shooting.
"Our thoughts and prayers are with everybody involved,” Trump tweeted. “Thank you to our phenomenal Law Enforcement Officers and First Responders that are currently on the scene.”

In response, Twitter Chief Executive Jack Dorsey tweeted: "We can’t keep being reactive to this, thinking and praying it won’t happen again at our schools, jobs, or our community spots. It’s beyond time to evolve our policies."
Last month, YouTube announced it would ban content promoting the sale of guns and gun accessories as well as videos that teach how to make guns.
Female mass shooters are rare. A recent Washington Post analysis shows only three out of 150 U.S. shootings with more than four victims since 1966 were done by women. In 2015, a husband and wife killed 14 people in San Bernardino, California.
