"...this guy is responsible for twenty or thirty more deaths at least, and there's a certain aspect of possessiveness in that. I think that's one way of describing it in rather bland terms, a possessiveness where the corpse could easily be as important as the live victim, in some respects. I mean, it's that physical possession and ownership, a taking, if you will, that is just part of the syndrome. I think that sense of power and ownership is one of the reasons why I think in some cases—not all, certainly—is why I think he might be individually intending to return to the scene to either view his victim, or in fact, interact with the body in some way."
