The liquidator of Josef Fritzl's estate says the basement of the house where Fritzl imprisoned and repeatedly raped his daughter for 24 years will be filled up with concrete.
Walter Anzboeck says the move is to ensure the space can never be entered again. He said in a statement Friday that concrete will be pumped into the basement early next year, once town authorities in Amstetten, about 120 kilometers (70 miles) west of Vienna, issue a permit.
The 76-year-old Fritzl was sentenced to life in prison two years ago after being convicted of holding his daughter captive in a windowless cellar, fathering her seven children and for responsibility in the death of one of them.
No decision has yet been made about whether the house should be torn down.
