The 73-year-old is accused of rape, incest, coercion and the death of one of the seven children he fathered with his daughter. Fritzl lured his daughter Elisabeth into the cellar of their home in 1984 and drugged and handcuffed her before imprisoning her. Three of Elisabeth's surviving children, a daughter aged 19 and two sons aged 18 and 5, were also locked up in the cellar with her and had never seen daylight.
