CAMP LEJEUNE, N.C. (WNCT/WNCN/AP) – One Marine is dead after another Marine is suspected of killing the Marine, officials said.

At around 10:15 p.m. on Wednesday, base law enforcement authorities apprehended a Marine suspected of involvement in the death of another Marine.

The incident occurred in an on-base barracks room earlier Wednesday evening.

The statement called the death a homicide and described the other Marine as a suspect but didn’t provide any other details, including how the Marine died.

Thursday evening on its Twitter account, Camp Lejeune announced NCIS has taken over the investigation.

The sprawling Camp Lejeune covers about 240 square miles (621 square kilometers) and is home to the II Marine Expeditionary Force. Its beaches and ranges provide training in amphibious assaults and urban warfare and it is used both for U.S. Marine training and for exercises involving other military forces from around the world.

The death came two days before the base was scheduled to conduct annual training known as Exercise Urgent Response that “provides an opportunity for tenant commands to develop and exercise emergency security procedures,” according to a press release.

In 2021, a Marine was shot and wounded in a barracks at the base. Authorities later determined that the shooting was accidental.
