On Tuesday afternoon, a woman allegedly shot and wounded three people before taking her own life at the YouTube headquarters in San Bruno, California. According to The New York Times, she died from a self-inflicted gunshot wound.
The three victims were transported to Zuckerberg San Francisco General Hospital, where one of them — a 36-year-old man — was in critical condition. The other two were women, ages 27 and 32.
San Bruno Police Chief Ed Barberini said the investigation is ongoing, and the shooter's motive is unclear. "We know very, very little right now, and we probably won't know more until tomorrow morning," Barberini said.
However, law enforcement officials told CNN the shooter is believed to have known at least one of the victims.
More than 1,100 people work at the YouTube office where the shooting occurred. Numerous employees took to Twitter during and after the incident.
We were sitting in a meeting and then we heard people running because it was rumbling the floor. First thought was earthquake. https://t.co/gmolQmRXm1

President Trump also used Twitter, posting a message expressing his thoughts and prayers to those involved.
Was just briefed on the shooting at YouTube’s HQ in San Bruno, California. Our thoughts and prayers are with everybody involved. Thank you to our phenomenal Law Enforcement Officers and First Responders that are currently on the scene.

Additional people, such as politicians and celebrities, sent their condolences to the victims, with some calling for stricter gun control laws. This included a trauma surgeon who treated the victims from Tuesday's shooting.
"To think that after we've seen Las Vegas, Parkland, the Pulse nightclub shooting, that we would see an end to this, but we have not," said Dr. Andre Campbell, an attending trauma surgeon at Zuckerberg San Francisco General Hospital and Trauma Center.
"Gun violence happens every day throughout the United States. It happens here in San Francisco. It happens in the Bay Area. It happens all over the country," Dr. Campbell said, adding that he thinks the media doesn't pay attention to other gun violence.
"I don't have all the answers ... at least we're having a discussion about it nationally," he said. "This is a real problem."
Google, which owns YouTube, released a statement about the shooting on Tuesday evening.
