HONOLULU (AP) — The Navy Sailor who fatally shot two people at Pearl Harbor before killing himself was unhappy with his commanders and had been undergoing counseling, a U.S. military official said Friday The sailor, G. Romero, also faced non-judicial punishment, which is a lower-level administrative process for minor misconduct, said the official, who spoke on condition of anonymity to discuss personnel matters not made public. Romero also wounded another person in Wednesday's attack at a naval shipyard before turning the gun on himself at the storied military base, officials said.

The National Park Service, which hosts the event with the Navy, declined to provide specifics on the heightened security measures, many of which aren’t readily apparent, Pearl Harbor National Memorial spokesman Jay Blount said.Read more on NewsOK.com
