You have to understand what the tape recordings were – we know serial killers sometimes take trophies - they take parts of their victims and sometimes they take souvenirs. They take something to remember them by. The recordings actually combine both of these things together it means you don’t have to relive it in memory in fantasy where things are not always as clear as they might be – all you’ve got to do is press the button and you are back there you can hear it what really happened. Remember we are not just looking at sexual perversion we are looking at sadism and the heart of sadism is the pleasure that comes from the control and domination of another person and the pleasure gained through their pain through their terror and every time you play the tape you go back there.
