A shooter on Tuesday wounded at least three people at YouTube’s headquarters in San Bruno, California, according to police.

“Active shooter at YouTube HQ,” Vadim Lavrusik, a YouTube employee, tweeted. “Heard shots and saw people running while at my desk. Now barricaded inside a room with coworkers.”

San Bruno police confirmed at least one person — a woman whom they believe to be the shooter — was dead of a possible self-inflicted gunshot wound. At least four people were injured, three of whom were shot, according to San Bruno Police Chief Ed Barberini.

• Some employees were safely evacuated between 15 and 20 minutes later.

• There were multiple 911 calls related to the incident, the city manager of San Bruno told the Associated Press.
• According to Recode: “The YouTube building is in a busy area of San Bruno, which is near the San Francisco airport. It is run in a separate location from the campus of Google in Mountain View, which is further south. The huge video platform is a unit of the search giant, which, in turn, is part of Alphabet.” The building’s main lobby is relatively accessible from the street, although it has security.
• Google CEO Sundar Pichai released a statement to employees about the shooting, saying the company was “very actively monitoring and working with local authorities and hospitals.”

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple of big issues with relying on ads and subscriptions to keep the lights on:

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. And we can’t do that if we have a paywall.

So even though advertising is still our biggest source of revenue, we also seek grants and reader support. (And no matter how our work is funded, we have strict guidelines on editorial independence.)

If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today? Any amount helps.
