Was David influenced by the Aramoana massacre,or even the Jeremy Bamber case(he had coincidentally visited New Zealand in the 1980s)? For how long had David been planning the killings does anyone know? From the videos on youtube and the pictures they look such a happy family,yet the atmosphere of that house must have been oppressive. How did David possibly hope to get away with the crimes using a simple paper round as subterfuge? I read on Wikipedia he was planning a holiday in Europe. Please:the man is sick,we don't want him..
