At least four others were injured in the incident in San Bruno, located near the San Francisco airport in northern California's Bay Area. The suspected shooter was found dead on the YouTube campus with an apparently self-inflicted gunshot wound, CNN reports. The shooting happened around 12:46pm in an outdoor cafe on the grounds of the headquarters, CBS San Francisco reports.
