CAMP LEJEUNE, N.C. (AP) — A Marine killed in a shooting at Camp Lejeune was identified by officials Friday as a 19-year-old lance corporal from North Carolina.

Austin B. Schwenk, of Onslow County, died Wednesday in an incident in a barracks room, the base said in a statement. Schwenk enlisted in 2022 and belonged to the 2nd Battalion, 6th Marine Regiment, the base said.

A second Marine was being held Friday on suspicion of being involved in the death, the base said. Officials called the death a homicide and described the other Marine as a suspect.

The Naval Criminal Investigative Service will investigate the death, the base said.

The sprawling Camp Lejeune covers about 240 square miles 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 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.
