Mary Duffy
Mary Duffy was a 23-year-old woman who became a victim of serial killers Geoffrey Evans and John Shaw in 1976, after Elizabeth Plunkett's murder. Duffy's tragic death led to the conviction of both men, although the lack of accountability in Plunkett's case continues to spark legal and public interest decades later.
