Inspector Thomas Cray:
Most people, when they see something like this, their immediate reaction is to ask how could somebody do this and why. Even when we catch the killer, they want to know the how and why. In movies or television, the killer always explains the how or why. He always has some reason, however crazy, with a mad gleam in his eye. But I've interrogated murderers like this one before, and let me tell you, they are well beyond the need to justify what they do. They just do it. Explanations are just a fiction to make us feel safe. Because if it can't be explained, then it's just meaningless chaos. It could touch any one of us at any moment. Which is exactly what it is
