If I understand it correctly the father has been found by a psychiatrist to be of sound mind. The mother is trying to pin the blame on the authorities because she warned them two years ago that something like this might happen but they still gave him custody as she was linked to prostitution. The mother is Brasilien, and I think in situations like this where one parent is Swiss and one is not the authorities tend to side with the Swiss parent if they are not married.

I think its the child the father tried to kill 20 years ago who is now in his 30's that is suffering from psychiatric problems.
