Homicide occurs before annual training

The incident comes two days before the base was scheduled to conduct its annual emergency response exercise.

The exercise "provides an opportunity for tenant commands to develop and exercise emergency security procedures," according to a news release from the base.

The release says the exercise also provides "realistic training opportunities meant to increase the installation's emergency response efforts, command and control, and security capabilities."

The base, located in Onslow County in southeastern North Carolina, occupies over 150,000 acres and has 14 miles of beach on the Atlantic Ocean.
