SAN BRUNO, Calif. — A woman opened fire with a handgun at YouTube’s headquarters in California on Tuesday afternoon, shooting three people — one of whom was critically injured — before killing herself, the authorities said.
The San Bruno Police Department identified the attacker late Tuesday as Nasim Najafi Aghdam, who was in her late 30s. The motivation for the shootings was under investigation, the police said, although her social media postings included criticisms of YouTube.
Zuckerberg San Francisco General Hospital received three patients: a man, 36, in critical condition; a woman, 32, in serious condition; and a woman, 27, in fair condition, a hospital spokesman, Brent Andrew, said at a news conference. A fourth person had injuries that weren’t from a gunshot, the police said.
“At this time there is no evidence that the shooter knew the victims of this shooting or that individuals were specifically targeted,” the San Bruno Police Department said in a written statement.
Word of the attack in San Bruno at YouTube, which is owned by Google and is one of the world’s largest social media companies, quickly spread online through employees’ social media feeds.
