In 2009 in Austria, a man named Josef Fritzl was sentenced to life for the imprisonment, torture and rape of his daughter Elisabeth for over 24 years.
While holding her captive in a dungeon, Fritzl fathered seven of Elisabeth's children while subjecting her to unimaginable cruelty and horror - the details of which reverberated around the world.
In 2024, his crimes are again making headlines because 15 years later, he is now eligible for parole.
Watch: Inside the horrific secret chamber where Josef Fritzl kept his daughter.
Although it's almost completely unknown, Australia actually has its own Fritzl-esque horror story. Crimes just as depraved and shocking that occurred in country Victoria, almost in parallel to the cruelty unfolding in Europe.
In 2009, Australian police quietly arrested a Victorian man in his late sixties for the systematic rape, abuse and imprisonment of his daughter *Katherine.
She was held captive for 30 years and gave birth to four of his children, one of whom died at just 12 weeks old.
Katherine was sexually abused so many times over the decades, detectives investigating the case found it impossible to count. All up, her dad was charged with 83 separate offences and at trial those charges were condensed into 13 counts of indecent assault, incest and assault.
