A woman opened fire at the YouTube headquarters in San Bruno, Calif., wounding four people before taking her own life, authorities said.
San Bruno Police Chief Ed Barberini told reporters Tuesday afternoon that one person, believed to be the shooter, was found dead of a self-inflicted gunshot wound. Four other people were taken to area hospitals for medical treatment, according to Barberini.
Lisa Kim, a spokeswoman for Standford Medical Center, said at least four patients from the shooting were expected to be admitted at the medical center.
“We do not know their conditions,” she said.
Brent Andrew, a spokesman for Zuckerberg San Francisco General Hospital and Trauma Center, said the hospital had “received several patients” and was expecting more.
Several YouTube employees sent tweets Tuesday afternoon, saying people were racing out of the company’s Cherry Avenue offices shortly after 1 p.m.
So far authorities do not believe this was an act of terrorism and appears instead to have been a case of domestic or workplace violence — although the investigation has just begun.
Witnesses in the area said they saw dozens of firefighters and police officers descending on the area. Other witnesses said they saw police holding rifles and other weapons
