Military officials are investigating a shooting at Camp Lejeune, N.C., on Tuesday, where a Marine gate guard killed a colleague with his service rifle.
The incident appears to be accidental and is not being considered an act of terrorism or an active-shooter scenario such as last week's deadly rampage at Fort Hood, Texas, the base said.
Officials referred to the shooting as a negligent discharge — and not intentional.
In the Fort Hood shooting, Spc. Ivan Lopez, killed three fellow soldiers and wounded 16 others at the Army post in Texas before taking his own life. The Army has said the shooting may have stemmed from a dispute over a request for leave. He was being treated for depression and anxiety, but there is no evidence linking those conditions to his military experience.
Authorities say the victim died of a single wound to the chest. Nat Fahy, a Camp Lejeune spokesman said the victim died despite attempts to revive him by base Provost Marshal officials who were first on the scene.
According to an official news release, the incident took place around 5:30 p.m. at the Camp Lejeune main gate. A Marine standing guard at the gate discharged an M4 rifle.
Officials said the slain Marine's identity is being withheld pending notification of next of kin.
Marine officials did not immediately have information about the Marine suspected in the shooting or whether charges had been filed.
The incident is under investigation by Naval Criminal Investigative Service, officials said.
Fahy said base residents were notified about the shooting on Facebook, but the base was not placed in lockdown.
