A woman opened fire at YouTube's California headquarters before turning the gun on herself, authorities said. Three other people were shot, one of whom was in critical condition.
San Bruno police identified the woman Tuesday night as Nasim Najafi Aghdam, 38.
Aghdam claimed on her social media accounts that YouTube was discriminating against her videos, many of which focused on animal rights and veganism.
Law enforcement officials said the woman approached an outdoor patio and dining area near lunchtime and opened fire.
Prominent technology company executives, including Tim Cook, chief executive of Apple Inc., and Jeff Bezos, chief executive of Amazon.com Inc., quickly expressed their sympathies.
