Cox Health teamed up with Springfield Police and Fire Department, Greene County Sheriff’s Office, and the Missouri State Highway Patrol as part of a training exercise.
The series of armed intruder drills began around 5:30 Monday and lasted until 9:30 at Cox South.
During the evening, people may have noticed a number of emergency response vehicles on campus.
This the second armed intruder exercises at a Cox Health facility.
Cox Branson held an exercise last year.
