SAN BRUNO, Calif. (AP) -- A woman opened fire with a handgun Tuesday in a courtyard at YouTube headquarters, wounding three people before fatally shooting herself in what is being investigated as a domestic dispute, authorities said.
Terrified employees huddled inside, calling 911, as officers and federal agents swarmed the company's suburban campus sandwiched between two interstate freeways in the San Francisco Bay Area city of San Bruno.
YouTube employee Dianna Arnspiger said she was on the building's second floor when she heard gunshots, ran to a window and saw the shooter on a patio outside.
She said the woman wore glasses and a scarf and was using a "big huge pistol."
"It was a woman and she was firing her gun. And I just said, `Shooter,' and everybody started running," Arnspiger said.
She and others hid in a conference room for an hour while another employee repeatedly called 911 for updates.
"It was terrifying," she said.
Two law enforcement officials identified the suspect later Tuesday as Nasim Aghdam of Southern California and said the shooting was being investigated as a domestic dispute. The officials spoke on the condition of anonymity because they were not authorized to discuss the case.
It appears the woman may have harbored ill wil toward YouTube itself. That's based on videos that she posted, accusing YouTube of shortchanging her on revenue from the site. In other videos, including one she posted on Instagram four days ago, she described herself as an artist, a musician, and a comedian.
Her videos on various social media platforms, including on YouTube often featured colorful costumes and backdrops. But in one video she accused YouTube of restricting her web traffic.
"If you go and check my videos, you see my new videos hardly get views.. My old videos that used to get many views, stop getting views. This is because I'm being filtered," Aghdam said.
She said she complained to YouTube's support team and says they told her that her workout videos were inappropriate.
Aghdam's father says she was angry at the company because it stopped paying her for videos she posted on the platform.
Ismail Aghdam told the Bay Area News Group that he warned police his daughter, Nasim Aghdam, might be going to YouTube because she "hated" the company.
Ismail Aghdam said he reported his daughter missing on Monday after she did not answer her phone for two days.
He said the family received a call from Mountain View police around 2 a.m. Tuesday telling they found Nasim sleeping in a car and he warned them she might go to YouTube.
Mountain View Police spokeswoman Katie Nelson confirmed officers located a woman by the same name asleep in a vehicle asleep in a Mountain View parking lot Tuesday morning.
She says the woman declined to answer further questions. Nelson did not respond to a question about whether police were warned Aghdam might go to YouTube.
They gave little information about the victims.
A 36-year-old man was in critical condition, a 32-year-old woman was in serious condition and a 27-year-old woman was in fair condition, a spokesman for San Francisco General Hospital said.
Witnesses described terror before officers arrived and discovered a victim near a front door and then found the shooter several minutes later with what appeared to be a self-inflicted gunshot wound, San Bruno Police Chief Ed Barberini said.
He said two additional gunshot victims were found at an adjacent business minutes later. Barberini initially said there were four people who had been shot but later clarified that a fourth person had suffered an ankle injury.
Zach Vorhies, 37, a senior software engineer at YouTube, said he was at his desk working on the second floor of one of the buildings when the fire alarm went off. He got on his skateboard and approached a courtyard, where he saw the shooter yelling, "`Come at me, or come get me."'
He saw somebody lying nearby on his back with a red stain on his stomach that appeared to be from a bullet wound. Vorhies said he realized there was an active shooter when a police officer with an assault rifle came through a security door.
He said the public can access the courtyard where he saw the shooter during work hours.
Michael Finney, a 21-year-old supervisor at Carl's Jr. across from the campus, said he came out of the bathroom to see a woman in a booth bleeding from the calf. Two friends were trying to stop the bleeding, using the victim's sweatshirt as a tourniquet, but it wasn't helping, he told the San Jose Mercury News.
"Everyone was figuring out what to do," Finney said. "I was trying to stay calm and see what I could do. Everybody is shocked."
Google, which owns the world's biggest online video website, said the company's security team worked with authorities to evacuate buildings and was doing whatever it could support the victims and their families.
YouTube's headquarters has more than a thousand engineers and other employees in several buildings. Originally built in the late 1990s for the clothing retailer Gap, the campus south of San Francisco is known for its sloped green roof of native grasses.
Inside, Google famously outfitted the office several years ago with a three-lane red slide for workers to zoom from one story to another.
"Today it feels like the entire community of YouTube, all of the employees, were victims of this crime," said Chris Dale, a YouTube spokesman. "Our hearts go out to all those who suffered."
The White House said President Donald Trump was briefed on the shooting and that officials were monitoring developments.
In a statement, San Bruno Mayor Rico Medina and city staff extended their support to YouTube and offered their best wishes for recovery from the horrible trauma.
Rep. Jackie Speier, D-San Mateo, said in a statement that she was shocked and saddened to hear about the shooting. She wished the victims a swift recovery and sent her support to everyone at YouTube who went through the traumatic experience.
"Unfortunately, gun violence incidents at workplaces, schools, places of worship or entertainment have become all too common. We cannot accept this as normal. We must take action to end gun violence," Speier said.
San Mateo County Supervisor David Canepa also issued a statement following the shooting.
"I commend the YouTube employees who maintained their composure during this tragic event and the incredible response by law enforcement officers who quickly secured the campus," Canepa said. "This is a resilient community that will recover with each other's support."
Sky Fox showed people walking out of the building being patted down by police.
One YouTube employee, Vadim Lavrusik, reported on Twitter being barricaded in a room with coworkers. He then tweeted he was out of the building safe.
Another employee, Todd Sherman, Tweeted saying he looked down and saw blood drips on the floor and stairs. He said he got out of the building safe and was in an Uber headed home. He Tweeted, "Police cruisers pull up, hopped out with rifles ready and I told them where the situation was as I headed down the street to meet up with a couple team members."

A neighbor tells KTVU she heard multiple gunshots, one after another before the gunshots started to get quieter. She heard a series of shots before a brief pause and more gunfire. Video shows a shattered window at the scene.
Seventeen-hundred people work at the YouTube campus.
Google Communications issued a message on Twitter saying they are coordinating with authorities and will provide official information from Google and YouTube as it becomes available.
