SAN BRUNO (CBS News/CBSLA) -- Terrified employees fled as gunfire rang out at YouTube's sprawling headquarters in San Bruno on Tuesday, prompting a massive police response and evacuation as victims were transported to nearby hospitals.
San Bruno Police Chief Ed Barberini said a woman was found dead from a self-inflicted gunshot wound. Three people were taken to hospitals with gunshot wounds.
The woman suspected in the shootings has been identified as Nasim Aghdam, 39, of Southern California, CBS News has confirmed. She lived in the Riverside County community of Menifee, authorities believe. Her father told CBS2 News late Tuesday that he had warned YouTube of his daughter's anger toward the video-sharing company.
A law-enforcement source had earlier told CBS News the wounded male was believed to be the suspected shooter's boyfriend. Armed with a 9 mm handgun, Aghdam asked for him by name, authorities told CBS News. Later Tuesday, authorities said they had no evidence she knew anyone who worked at the company's headquarters.
Barberini said police arrived on scene at 12:48 p.m. local time as encountered frantic employees fled the building after several shots were reportedly fired at the outdoor cafe on YouTube's campus. "It was very chaotic as you can imagine," he said.
Responding officers encountered one victim with a gunshot wound toward the front of the building before finding the deceased suspect, Barberini said. Several minutes later, police located two additional victims at an adjacent building.
Employees at the YouTube offices in Playa Vista were given the option to go home after the shooting at the company's headquarters, according to CBS2's Joy Benedict.
Hospital update on victims
A spokesman for San Francisco General Hospital told CBS News it has received three patients: a 36-year-old man in critical condition, a 32-year-old woman in serious condition and a 27-year-old woman in fair condition.
Heavily armed police surrounded the facility, with armed SWAT vehicles stationed outside. Police officers could be seen patting down employees evacuating the campus to a nearby parking lot, where they were surrounded by police cars.
White House press secretary Sarah Sanders said President Trump has been briefed on the shooting and they are "monitoring the ongoing situation."
On Twitter, Mr. Trump as well as Apple CEO Tim Cook offered thoughts and prayers to those affected in the shooting.
From everyone at Apple, we send our sympathy and support to the team at YouTube and Google, especially the victims and their families.

Several employees tweeted they heard gunfire Tuesday afternoon. Vadim Lavrusik said he barricaded himself and others inside a room before they were able to escape safely.
