This photo in the article was taken as a joke (they used nutella or so), here you have a photo of her from her father's FB profile when she was 16. The very post above the photo speaks for itself "Hot chick for the taking".
Unfortunately, but the only chance for this girl her to be declared insane or incapable of judging her own actions. Otherwise she will end up in prison, where as a child killer she will have no life.
The mentality in small Polish towns/villages is completely different from that in big cities. For the most part, poverty reigns there, the vast majority of people are uneducated, unfamiliar with proper social relations. Her father, who comes from a large city, very easily took advantage over the local community and very quickly set them up for himself, which is why everyone kept quiet. In my opinion, he is the one who should land not in jail but on the hook for what he did to those children, and the children (regardless of age) should get immediate help, but that won't happen.
A terrible case, and the worst thing is that it happened in front of EVERYONE - and no one did anything about it.
