Amstetten, Lower Austria. A locked, windowless cellar. An 18-year-old disappears and is declared a runaway.
For 24 years, the truth sits beneath the family home. She is imprisoned by her father, coerced into letters to keep police away, and forced to bear seven children, three grow up entirely underground.
In 2009, the façade collapses in court. He pleads guilty to all counts. He is sentenced to life. In 2024, a court approves his move to a regular prison. The sentence stands.
The Case in One Line
Josef Fritzl imprisoned his daughter Elisabeth in a concealed cellar beneath the family home in Amstetten for nearly 24 years (1984–2008). During that captivity he repeatedly raped her and fathered seven children. In March 2009, he pleaded guilty to all charges, including murder by neglect of a newborn, was convicted, and received life imprisonment with placement in a secure psychiatric institution.
How It Started
Elisabeth Fritzl as a teenager.
Late August 1984, Elisabeth (18) vanished. Her father told relatives and authorities she had run away. Letters followed, written under duress, reinforcing the lie. Behind the door and a concealed entrance, a custom-built cellar trapped her out of sight. According to contemporaneous timelines and court reporting, the captivity began with drugs and restraints, then locked confinement.
The Hidden Family
Between 1988 and 2002, seven children were born. Three were taken upstairs and presented as "found" infants. Four remained below, the oldest two and, later, a boy born in 2002. In 1996, twins were born in the cellar; one, Michael, died shortly after birth. Prosecutors later argued he could have survived had medical care been sought. That decision, choosing concealment over treatment, became the core of a murder-by-neglect count.
The Break in the Cover Story
On April 19, 2008, 19-year-old Kerstin became critically ill. Fritzl brought her to a hospital in Amstetten. Doctors appealed publicly for the mother to come forward with medical history. Police attention shifted. Within days, Elisabeth emerged during questioning and disclosed the cellar. On April 26, police arrested Fritzl near the hospital. Two days later, he confessed to the imprisonment and the paternity of the children.
Charges and Trial
Prosecutors filed an indictment on November 13, 2008. The counts included murder by neglect (for Michael), enslavement, rape, incest, coercion, and deprivation of liberty. The trial opened March 16, 2009, in St. Pölten. At first, Fritzl pleaded not guilty to murder and enslavement, but after jurors viewed Elisabeth’s recorded testimony (11 hours) he changed his plea to guilty on all charges.

Sentence
On March 19, 2009, the court convicted him on every count and imposed life imprisonment. The presiding judge ordered placement in a secure psychiatric institution for mentally abnormal offenders. Security measures remained strict; media noted suicide watch protocols immediately after sentencing. The conviction and psychiatric placement were affirmed by reporting across multiple outlets and languages.
Where It Stands Now
Legal movement continued years later. In October 2012, media reported a divorce from his wife. In May 2024, amid reports of dementia, a higher court in Austria approved his transfer from the psychiatric unit to a regular prison. This did not shorten the sentence. Parole remains denied. The life term continues.
Why This Case Broke Through
It combined calculated concealment with institutional blind spots. The letters, the staged “foundlings,” and a basement designed to be missed, each step insulated the crime until a medical emergency forced daylight. Investigators credited the hospital appeal and the rapid focus on the family narrative for breaking the case.
Outcome
Life imprisonment. Ordered placement in a secure psychiatric institution (2009). Transfer to a regular prison approved (2024). Parole still denied.
