Cold Case Files

Unholy Secret

In Toledo, Ohio in 1980, a woman's body was found in a chapel, covered only by an altar cloth. She had been stabbed 31 times. The woman's name? Sister Margaret Ann Pahl. Somebody had murdered a nun.

Based on the iconic, Emmy-nominated series on A&amp;E, this show explores some of the most difficult-to-solve murders, which stymied investigators and went cold, sometimes for decades. In fact, one-third of all murders in America remain open. But thanks to dogged investigators and breakthroughs in forensic technology, these cases become part of the rare 1% of cold cases that are ever solved. Cold Case Files is hosted by Paula Barros.
