London, Mar 21: Dungeon girl Elisabeth Fritzl wants her father Josef to rot in jail, it has emerged.

The 42-year-old told her lawyer that she wanted the fiend, who raped her 3,000 times, locked away for the rest of his life.

Elisabeth said justice chiefs in Austria owed that to her murdered son Michael, who died because Fritzl, 74, would not seek medical help.

Yesterday, lawyer Eva Plaz revealed how Elisabeth bravely attended the four-day trial in St Poelten, reports The Sun.

It was Elisabeth's decision to face her father that forced him to change his pleas to guilty.

He was convicted of murder, rape, slavery, incest, deprivation of liberty and coercion at the House of Horrors in Amstetten.

He was sentenced to life in a secure psychiatric institution. (ANI)
