I get what you're saying. I guess I could have been more clear about my thoughts when I wrote that he uses his "hobby" as an out. Again, it's anecdotal so may be a useless train of thought. In my life, I knew someone who seemed fairly normal in the beginning. Certain red flags about his behavior appeared as time went on. Though married with children, he was always sort of a loner but suddenly developed an obsession with fishing. He bought a boat, would spend hours alone fishing, etc. Later we found that the fishing was an excuse to be away from his family, to be "alone," to get up to the things that he was really interested in. Does that make some sort of sense as to where I was going with the railroad idea? I was thinking BG might often make excuses if he lives with someone for why he's gone on his "outings." If anyone were to say to him, "Hey, weren't you at the Monon High Bridge the last time we went to Delphi?" He might say, "Sure, I went but only to check out the old trestle." He might use his so-called hobby to normalize his behavior, which in fact includes stalking, rape, or more. This is all speculation, of course! Just another way of thinking about why a person who wanted to kill two girls would be in that place at that particular point in time.
