Fritzl case
In 2008, Elisabeth Fritzl told Austrian investigators that her father, Josef Fritzl, had held her captive in a concealed cellar in Amstetten for 24 years, during which he repeatedly raped her, resulting in the birth of seven children. Fritzl pleaded guilty to all charges in March 2009 and was sentenced to life imprisonment.

Overview
The Fritzl case came to light in April 2008 in Amstetten, Lower Austria, when Elisabeth Fritzl (born 6 April 1966) was able to inform authorities that she had been held captive by her father, Josef Fritzl (born 9 April 1935), in a concealed basement chamber beneath the family home for 24 years. During her captivity, Fritzl repeatedly raped her, resulting in the birth of seven children. One infant died shortly after birth and was cremated by Fritzl. Three children were raised in the family home upstairs, with Fritzl and his wife Rosemarie presenting them to authorities and neighbours as foundlings. Three other children remained with Elisabeth in the cellar throughout their lives until the case's discovery.
Captivity and Discovery
Fritzl lured Elisabeth into the cellar on 28 August 1984 under the pretext of needing help with a door, then drugged and imprisoned her in a chamber he had secretly built. Over the following decades he entered the chamber almost daily, bringing supplies while continuing to sexually abuse her. The case was uncovered in April 2008 after Kerstin, the eldest daughter held in the cellar, fell seriously ill and was taken to hospital. Hospital staff grew suspicious of Fritzl's account, and following police investigation and Elisabeth's eventual disclosure on 26–27 April 2008, Fritzl was arrested. DNA testing on 29 April 2008 confirmed he was the biological father of Elisabeth's children.
Criminal History and Suspected Murders
Fritzl had a prior conviction for a 1967 rape in Linz, for which he served twelve months of an 18-month sentence; under Austrian law this record was expunged after fifteen years, which meant social services did not uncover it when he later sought approval to foster his grandchildren. Following his arrest, investigators examined Fritzl as a possible suspect in several unsolved killings, including the 1986 murder of 17-year-old Martina Posch near a campsite he ran, the 1966 death of 17-year-old Anna Neumayer, and the 2007 murder of Gabriela Supeková. He was not charged in connection with any of these deaths due to insufficient evidence.
Trial and Sentencing
Fritzl's trial began on 16 March 2009 in St. Pölten before Judge Andrea Humer. He initially pleaded guilty to most charges but contested murder and grievous assault allegations relating to threats to gas his captives. After Elisabeth's recorded testimony was played in court, and after learning she was present in the courtroom, Fritzl changed his pleas to guilty on all counts. On 19 March 2009, he was sentenced to life imprisonment, with a minimum of fifteen years before parole eligibility. He did not appeal.
Aftermath
Elisabeth, her six surviving children, and Rosemarie received medical and psychological care following their rescue. In later years, developments concerning Fritzl's detention status were subject to court review, including a psychiatric-facility-to-prison transfer that was contested and litigated through 2024.
