London, Aug 4 : Austrian prosecutors are mulling over whether to charge Dungeon dad Josef Fritzl, 73, with slavery to maximise the time he serves in jail.
Fritzl has admitted to having imprisoned his daughter Elisabeth for 24 years in a secret cellar beneath his home in Amstetten, where he fathered six children with her. While he kept three of the incest children with him and his wife Rosemarie, 68, in their upstairs apartment, the other three lived with Elisabeth in the concrete bunker until police rescued them on April 26.
One of the kids, a baby boy called Michael, died soon after he was born, and Fritzl burnt his body in an incinerator.
However, it was revealed last month that Fritzl could only be facing 10 years in jail because of multiple convictions are prohibited in Austrian law, and the only charge that can be proved in court was that of incarceration.
The prosecutors' case weakened further when it was revealed that the kids who lived in the cellar might refuse to testify against their father.
