The Killing of Village Women in Negrive

Negrive in Hungary has been dubbed the murder district. Women start poisoning parents who have grown too old and are hard to care for. They also poison children that they can't feed any more. When some of the women discover they can inherit land and money from relatives, they start killing their relatives too. It goes on for ten years with nobody saying anything, and and no one getting caught. Authorities step in after noticing a huge gap between births and deaths.
