Police say a man dressed in all black opened fire in a crowded bar in Thousand Oaks, California, last night, killing 12 people — including a sheriff’s deputy. The shooter is also dead, though it remains unclear how he died. Ventura County Sheriff Geoff Dean described a “horrific scene” at the Borderline Bar & Grill. “There’s blood everywhere,” he told reporters early Thursday. Officials from the FBI’s Joint Terrorism Task Force, as well as members of the U.S. Bureau of Alcohol, Tobacco, Firearms & Explosives, were dispatched to the area.
