In the vinyards along the Rhein near here a 13 year old girl was abducted on her way home from school and murdered. No clues. And yesterday in Heilbronn, a city known for its ties with the Romantic literary tradition, a 22 year old policewoman was shot in the head and died. No clues. She had just finished her training for the profession she had always dreamed of, had just found boyfriend with whom she had fallen in love.
