MELBOURNE, Fla. (AP) - A 72-year-old Florida woman was accidentally shot by her husband during a "robbery drill" the couple staged to practice how they'd respond to an intruder.

The Brevard County Sheriff's Office says Arnold and Patricia Morris had little experience with guns, and the shooting Sunday was an clearly accidental.

Arnold Morris called 911 after the .380-caliber pistol fired, and his wife was airlifted to the hospital for surgery.

The two were fortunate to escape serious injury. Patricia Morris is expected to make a full recovery.
