A gunman opened fire late Wednesday night inside the Borderline nightclub in Thousand Oaks. Now identified as Ian Long, 29, a Marine Corp veteran from Southern California. Twelve people, including veteran Sheriff Deputy Ron Helus, were shot dead late Wednesday night. The gunman was found dead inside the nightclub after the second wave of police arrived after Helus’ death. It appears that the gunman’s wound was self-inflicted. Witnesses said the gunman was dressed all in black and deployed smoke bombs before opening fire on the dance floor.
