Rose West and Myra Hindley

Rose West and Myra Hindley were referred to in prison as the gruesome Tucson. Rumors spread that the pair were romantically involved, though they allegedly had a falling out over who was more infamous. Rose watched on impassively, showing no emotion, except when Heather's name was mentioned. Only then did she dab her dry eyes with a tissue. Their crimes are covered in episode 49 of Case File, The Moors Murders.
