Prosecutors claim Fritzl was responsible for the baby boy’s death because he neglected to seek help. They say he disposed of the body in a furnace.Below his home in the town of Amstetten, Fritzl kept his daughter Elisabeth and three of their children in a windowless cellar. She claimed that during the early months of her imprisonment, she was kept on a leash. While they were incarcerated in their 60 square metre dungeon – in parts only 1.70 metres high – Fritzl had no qualms about sunning himself on holiday – he was filmed enjoying a trip to Thailand. And despite his actions which shocked the world, Fritzl underwent a psychiatric assessment last year which concluded he knew what he was doing, and is fit to stand trial. When one of the three captive children fell seriously ill last year, hospital doctors appealed for her mother to come forward with details of her medical history. The secret was out. Elisabeth and her six children are now living under new identities at an undisclosed location.
