A woman shot three people and then turned the gun on herself Tuesday at YouTube headquarters in San Bruno, CA, setting off a chaotic scramble as workers dived for cover, hid in closets and ran from the building, reports the San Francisco Chronicle .
San Bruno police and San Mateo County sheriff’s deputies rushed to the normally quiet office park shortly after the first reports of gunfire came in at 12:48 p.m. and saw dozens of workers running out of the exits.
