It's all about psychology and percentages isn't it?
If you had just killed your neighbour/friend/lover, how would you think? It would be something along the lines of
O.M.G !!!***!!! what am i gonna do now? anic:
The body of a person you know is far too close for comfort. The Police are sure to come knocking at my door. But if the body is found 3 miles away, their psychologically placing a distance barrier between them and the body. Their way of thinking is, a body found three miles away could be the work of a wider area of people. It Lowers the percentages of it being someone close to home.
It's all panic reaction, they have to do something to try cover thier tracks. The truth is their pretty much stuck, damned if they do, and damned if they don't. But they don't have much time to think straight.
And the sexual thing.
The Police 'think' there may have been a sexual motif. Once again their assuming that's why pretty young girls are killed, but they have no proof to back it up.
Just my thoughts on it.
And interesting thoughts they are... But, IMO someone who has just murdered a neighbor, and who panics would be more likely to display that panic by removing * themselves * from the area of the murder,rather than the dead body ? And, I have to confess : I do not know what a "sexual motif " would be in the context of this crime ?
