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."
