Do you think Josef Fritzl's wife was unaware that he had a dungeon under the house where he kept his children?

24 years of not hearing from the daughter but she keeps leaving babies on the doorsteps. She had to of known because a normal mother not knowing where her daughter was for that long would be asking questions and asking the police or organizations to help her find her daughter. And could you live that long in a house and not know about a secret basement, doubtful.
