Before she goes home she needs to make a quick stop at her office in the Physical Education Building. She weighs her options. She could walk outdoors through the dimly lit patio area between the women's locker room and men's locker room, or she could walk through the massive and virtually empty women's locker room. Each choice makes her mildly apprehensive, but she chooses the latter route. As she walks down the corridor of the 21, square foot facility she feels a presence, turns and is startled to see a young man on roller blades gliding close behind her. He stops periodically to look between the aisles of lockers.
