A female suspect is dead and at least three people were wounded in a mass shooting incident Tuesday at YouTube headquarters in California. Hundreds of company employees fled the chaotic scene. San Bruno police swarmed the YouTube offices after receiving numerous emergency calls reporting shots fired. Police Chief Ed Barberini said that officers encountered one victim with an apparent gunshot wound in front of the business, and soon thereafter encountered a female who was dead of what appeared to be a self-inflicted gunshot wound.
