News of a reported shooting at the YouTube offices in California unfolded in real time on social media Tuesday as employees live-tweeted what was happening.
Vadim Lavrusik, a product manager at YouTube, was one of the first people to report the shooting at the company’s headquarters in San Bruno, tweeting at about 1 p.m. local time:
Active shooter at YouTube HQ. Heard shots and saw people running while at my desk. Now barricaded inside a room with coworkers.— Vadim Lavrusik (@Lavrusik) April 3, 2018
San Bruno police responded to the shooting and advised people to stay away from the area. The Associated Press and others, citing law-enforcement officials, report the shooter was a woman and has died of a self-inflicted gunshot wound.
A spokesman for Zuckerberg San Francisco General Hospital told reporters Tuesday that three people were taken to the hospital with injuries, according to the AP. They include 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. All three patients are conscious and have not undergone surgery, according to Andre Campbell, a trauma surgeon at the hospital.
