An active duty U.S. sailor whose submarine was docked at Pearl Harbor opened fire on three civilian employees Wednesday, killing two and then taking his own life just days before dignitaries and veterans descend on the base for the 78th anniversary of the Japanese attack. The commander of Navy Region Hawaii, Rear Adm. Robert Chadwick, said he didn’t know the motive behind the shooting at the Hawaii base’s naval shipyard that left the third civilian Department of Defense employee hospitalized. The sailor was assigned to the fast attack submarine USS Columbia, which is at Joint Base Pearl Harbor-Hickam for maintenance.
