Elizabeth has been held captive since

Police investigating the incestuous kidnapping case in Austria say Josef Fritzl had been planning a dungeon as early as 1978, six years before he locked his daughter Elizabeth up for 24 years as a sex slave. Doctors said her first child born in the dungeon was still in a serious condition. But the rest of the family was improving. Therapists have bought toys and an aquarium for the children and given Elizabeth and her younger sons special sunglasses because their eyes are still sensitive to daylight.
