Good theory. A thought crossed my mind when reading your thoughts. Maybe someone did pose as Judith. Her rings were missing.
They found hair on her clothes that resembled horse hair. Judith loved horses so LE thought she had visited a lodge where they had horses. It was written about in the article about the "Boys from Bumcombe" (I might have the title wrong.) LE had the lodge checking the register but It doesn't look like they found her name or I think it would have mentioned.
I don't know if they did DNA or not. I don't believe they did or they would know for certain whether it was horse hair or not. Assuming they kept it. I read one article that said her clothes had slice marks which could have been from a knife. No knife was found at the scene.
Judith was a big woman so she almost had to walk to the camp on her own (or forced). It was a very steep area and carrying her would have been almost impossible. Her husband could not have gotten there at all. He had trouble breathing with normal walking.
I wonder if the hair was tested or could it have been hair from a bear. Maybe she wasn't murdered but attacked by a bear. Maybe it wasn't a shallow grave but an area Judith had dug out just enough to lay down in to protect from the wind and to not be seen by a preditator. For safety. She was an experienced camper. The blanket was in the shallow grave too. Why bury the blanket and not the rest of her things?
Black bears rarely attack adult humans but if she ran into a mother with cubs it might have attacked. A male would attack too. If she fell asleep and woke up to a bear standing over her she didn't have a chance.
If she had food with her (she purchased a bunch of sandwiches) a bear would come to her camp. Maybe she lost the rings during the attack or when other animals chewed on her corpse. Sickening but possible. The bear could have taken her head off in the attack.
My question to LE.......could it have been a bear?
Here is an article about the bears in Piscah that leads me to wonder:

The next thing is the car. Suppose she rented the car and it was towed as abandoned or picked up by the rental company. They didn't use computers as much in 1997 so it would have been harder to know who towed it or who rented it to her. There were places at used dealerships that used to rent cars for cash off their lots. If it was towed the towing company might have called the dealership and the dealership could have picked it up not even knowing the circumstances. The tow company could have kept it on their lot for a certain amount of time, applied for the title, and sold it.
Remember NC wasn't looking for her..............
my bold
I hope they had the animal hair tested or looked at by a professional to be sure of what kind of animal it came from. She could have got that animal hair on her clothes in NC or back home, but you make an excellent point about the bears. It could have been a transfer of animal hair from someone else's clothes as well.
