It takes all kinds. I look at things from the psychological aspect of a predator, so I suppose I'd consider myself more of an armchair profiler. I'm interested in the ways in which people become victims, how they wind up on the radar of a predator, and what a predator then does when once he makes the decision to strike. I'll bet if you and I sat down and looked at a map and then compared it to a list of known offenders within the geographical parameters, we could probably solve this damn thing together.
Off-topic, have you read the novel 'The Pledge?' It's an old German one that's been translated into English and it's kind of a meta exploration of detective novels and their tropes, confronting the reader, ultimately, with the ugly truth that sometimes, the bad guys get away and even if you're right, that doesn't necessarily mean anyone's gonna listen to you. The full title, in fact, is actually 'The Pledge: Requiem For The Detective Novel,' which is quite fitting. Worth a read if you're into it!
