YouTube employees came running out of buildings on a sprawling tech campus with their hands in the air and on their heads amid reports of an active shooter Tue., April 3, 2018.
A female shooter entered the headquarters and shot three people before killing herself, officials said. Police and federal agents quickly surrounded the building. Investigators later said the attacker harbored a grudge against YouTube and, contrary to early reports, did not know any of the victims personally.
