I agree with your post FromGermany.
BG is like a daylight phantom, and strikes in secluded places. Able to
slip in and out without raising much suspicion. He may have attempted similar crimes or even been successful before, but this time all the variables that had to work in his favor, did, and he murdered two juveniles.
I'm of the opinion he'll be caught, eventually. Serial killer IK murdered in secluded and even remote areas, we don't even know the names of most of his victims. He was able to murder and slip away in most of his crimes, without the notoriety and sensationalism which has happened in the Delphi case. He didn't want it, early on. Then IK changed his tactics, and got caught. He went against his own "rules", but I think too something in his mind might have been telling him to get caught, while at the same time he had to ratchet up the thrill in his killings.
BG went all-out in this case, what we know about it is frightening, and that has to be what BG is after. Scare the families. Scare the town. Scare people in Indiana and surrounding states. Scare people who like walks in the woods. Scare people all over the world paying attention to this case.
I know I was scared, and I'm about BG's size, maybe bigger. I look over my shoulder while out walking trails here in Indiana. BG has affected millions of people all over the world, and I believe that was the aftermath he desired, and he gets off on the notoriety. Yet when he strikes again, he may change his tactics some, and may even try to surpass the brazen attack he did that day.
