When Gail Bell was 17, she was shot in the back. Coming home from evening class later than usual one night, she took a short cut through the dark streets of a new estate, unaware she was being watched. When a car began following her, she felt a jolt of fear. Then the car stopped and out of the eerie silence came a cracking sound as a bullet struck her from behind. The car sped away and the shooter was never found.
