Fritzl II.

A doctor was suspicious of the claim by Josef Fritzl that his daughter was in a cult when Kerstin was hospitalized, and he was going to find out the truth, no matter where it led:

"I did not like his tone and something did not seem right. What made me particularly suspicious was that he did not seem to think it important the answer any of my questions, simply demanding we make Kerstin better so that he could take her away again."

A closer examination of Kerstin, 19, revealed more mysteries.

The teenager had almost no teeth, and a letter apparently left by the mother in the girl’s clothing did not fit with the grandfather’s claims that the mother was not concerned about her child.

"I could not believe that the mother of a seriously ill 19-year-old girl would simply load her off at the hospital and disappear. From the tone of the letter the mum had sent it was clear that she cared very deeply for her child."

As Kerstin’s condition worsened the doctor decided to act outside of the medical sphere - and to start a one man campaign to track down the mother.

Reiter's suspicions paid off, for only then was the ugly truth about Josef Fritzl known.
