Shooter Opens Fire at YouTube Headquarters

UPDATE 4/4: San Bruno police identified the shooter as 39-year-old Nasim Najafi Aghdam, a San Diego resident.

"The San Bruno Police Department is investigating a motive for this shooting. At this time, there is no evidence that the shooter knew the victims of this shooting or that individuals were specifically targeted," the department said in a statement.

As The Mercury News reports, Aghdam had a presence on YouTube and was annoyed that her videos were being "filtered." She disappeared recently, prompting her father to call police and warn them that she might be going to YouTube because she "hated" the company, the paper says. Mountain View police located Aghdam in a parking lot, spoke with her, and notified the family early on Tuesday that she'd been found. She was released and attacked YouTube later that day.

UPDATE 8 p.m. ET: Chief Barberini clarified that of the four people transported to the hospital, three were shot and a fourth suffered a non-gunshot-related injury, possibly a sprained ankle sustained while trying to flee. Google CEO also sent the following note to employees:

UPDATE 5:45 p.m. ET: San Bruno Police Chief Ed Barberini says four victims have been transported to local hospitals with gunshot-related injuries.

The suspected shooter, a woman, is dead of what officials believe is a self-inflicted gunshot wound. At this point, police do not know if the woman worked at YouTube.

Law enforcement is currently conducting a "methodical, slow search" of the building, Barberini says. All employees have been evacuated and several hundred were taken to a nearby location so police can question them about what they witnessed.

On Twitter, employees inside YouTube headquarters posted about being locked in rooms and being evacuated. Local news showed footage of fleeing workers being frisked by police as they exited the building.

Vadim Lavrusik, who works in product management at YouTube, tweeted that he "Heard shots and saw people running while at my desk." After being "barricaded inside a room with coworkers," he was able to safely evacuate.

YouTube's San Bruno offices are about 25 miles north of Google's Mountain View headquarters.
