HONOLULU, Hawaii (KGTV) -- A U.S. Navy sailor killed two U.S. Department of Defense civilian employees and wounded another before turning the gun on himself at Pearl Harbor Naval Shipyard, according to Hawaii News Now .
The two victims who died were men, but their identities haven't been released at this time. The third victim, a 36-year-old man, is currently in the hospital.
Around 5:30 p.m. PST, a spokesman said the situation had been "contained." A witness reported seeing the gunman, a sailor assigned to the USS Columbia, fatally shoot himself.
It's unclear whether or not the gunman knew the victims, Rear Admiral Robert Chadwick told Hawaii News Now.
