The San Bruno Police Department has confirmed that the woman whopeople at YouTube's headquarters before turning the gun on herself was Nasim Najafi Aghdam, a 39-year-old resident of San Diego.
Aghdam was found dead Tuesday on YouTube's campus in San Bruno from what was reportedly a self-inflicted gunshot wound.
Aghdam reportedly had a number of YouTube accounts and a website where she had voiced concerns about YouTube and its monetization policies. She reportedly had no relationship with anyone at YouTube's headquarters. Her YouTube accounts have since been shut down.
Aghdam's family told CBS Los Angeles that she had become increasingly upset with YouTube when the site stopped paying for the content she posted online. Prior to the shooting, Aghdam's father said she had been missing for a few days.
In a separate interview with Fox 5 Las Vegas, Aghdam's brother said he'd warned police that she'd driven from San Diego to the Bay Area, and that he was worried she might do something.
YouTube employees began posting to Twitter about a shooting around 1 p.m. PT and described a chaotic situation.
Aghdam allegedly shot three people: a 32-year-old woman, a 27-year-old woman and a 36-year-old man, all of whom were transported to the Zuckerberg San Francisco General Hospital with gunshot wounds. San Bruno Police Chief Ed Barberini said the wounds were treatable.
The San Bruno Police Department is continuing to investigate the motive for the shootings.
"At this time," read a statement, "there is no evidence that the shooter knew the victims of this shooting or that individuals were specifically targeted."
Google did not offer comment and referred back to comments made earlier by Google CEO Sundar Pichai.
YouTube CEO Susan Wojcicki tweeted on Tuesday, "There are no words to describe how horrible it was to have an active shooter @YouTube today. Our deepest gratitude to law enforcement & first responders for their rapid response. Our hearts go out to all those injured & impacted today. We will come together to heal as a family."
