Sister Margaret Ann Pahl was stabbed to death on April 5, 1980, Holy Saturday and the day before her 72nd birthday. There was nothing random about the identity of this victim, or when she was killed.
In 1968, Sister Annunciata became Sister Margaret Ann Pahl. Only two years before the Sisters of Mercy had allowed the nuns to use their baptismal names. She had taken the habit over 50 years before.
