Elisabeth’s father, 73-year-old Josef Fritzi, started sexually abusing her when she was 11 and, seven years later, handcuffed and locked her in their cellar. A letter later arrived at the Fritzi’s doorstep, supposedly from Elisabeth, stating that her parents should not look for her. Elisabeth’s mother figured that she had disappeared at her own will, completely unaware that her daughter was being held prisoner in the cellar. She was also unaware that Josef fathered seven children with his daughter during these 24 years.
