Happy to be here. Seems like a well informed group. We should be able to sort some of this out.
I agree that running into that path may not have been the best choice, but as I said a few posts back when I was being stung by a whole bunch of bees I ran in a panic, I was not in control of my direction, I was just trying to get away. Similarly, I had a friend who was killed in a motorcycle accident. A car turned in front of him and he slammed the brakes. He went straight into the side of an SUV. If he had chosen instead to swerve, he would have crashed into an empty grassy median. The point being that when under extreme duress, and having to make critical decisions in fractions of seconds, intellect and reason gonout the window. I still see it as a possibility. He attacks, she breaks free and just runs. Ends up down the path. If you asked her she'd tell you she didn't know why she did it, because she wouldn't know- she was panicked. Just a hypothetical of course.
I think it's quite plausible that she is the one who went down the path first. She would have been familiar enough with the area to know that the path didn't lead into a vast stretch of woods, but is rather close to houses, escape, etc. And in a panic, I can envision that she would go down that path to avoid a scary person or situation. I don't know if that happened, but I'm adding it to my list of possibilities. I appreciate the new idea to our collective brainstorming.
As for the perp, I very much agree this wasn't a crime that was planned in advance.
He could be local as in he lives in the area, or he could be someone "local" just in the sense that he has driven that road before. I'm also leaning toward someone who spends time outdoors, either in profession or as pastime. AND/OR, he spends time driving.
Both my dad and my husband had very good skills about finding little paths like these off roads - for hiking, picnicking, etc. And, I recall high school boyfriends who could quickly find paths like this for make-out sessions in cars.

I don't think the perp had to be super familiar with the area to know about the path....or to simply be able to spot it. Paths off highways are not that uncommon, after all, even if they aren't obvious to a person not paying attention.
And, I do agree with the profiler that the perp simply blended back into his daily life. That doesn't seem too peculiar, though. I mean, what else is he supposed to do? I guess that means the perp does have a social life, not a socially-awkward person. I also get that vibe from the case, though not based on evidence - just a vibe that the perp was someone who passed as "normal."
I'm still leaning toward random crime of opportunity by someone who has been in the area before, but not necessarily a resident of that particular town.
I hope the perp is caught before striking again.
