A sailor from the USS Columbia submarine killed two civilian workers at the Pearl Harbor Naval Shipyard and injured another Wednesday before taking his own life, authorities say. No motive has been identified for the shooting and it's not clear whether the sailor targeted the workers or was firing indiscriminately, the New York Times reports. US Navy Rear Admiral Robert Chadwick says all three victims are male Department of Defense employees, reports the Honolulu Star-Advertiser. Authorities say the injured man is in stable condition. The Columbia is in dry dock for maintenance at the shipyard, which is across the harbor from the Pearl Harbor National Memorial. Authorities have not released the name of the shooter or disclosed what kind of weapon he used.
The shipyard is part of Joint Base Pearl Harbor-Hickam, which went into lockdown for hours after the shooting started at around 2:30pm. "Our thoughts are with the families of the victims and everyone involved. I can say that we are mobilizing support services for naval shipyard personnel as well as everyone else who may be affected by this tragic event," Chadwick said in a statement. Hawaii Gov. David Ige said state and federal authorities have offered assistance. "I join in solidarity with the people of Hawaii as we express our heartbreak over this tragedy and concern for those affected by the shooting," he said. The shooting happened just three days before the 78th anniversary of the Japanese attack on Pearl Harbor, reports the AP. (Read more Pearl Harbor stories.)
