Hi!
First time poster on this thread. I have been reading this closely, but I stopped because my mind is racing with possible information.. I hope that I am not bringing up stuff that was already discussed but if I do sorry. I plan on finishing reading tonight.
1) I honestly do not believe Jon and Jane were sibling. As much as I love my little brother I wouldn't want to go travel with him. I am 26 and he is 25, it just doesnt sound fun. It is more appealing to be traveling with a bf or gf than a family member.
2) I find it amazing that in a small town no one really remembers these individuals. They were not average "joes," they were good looking and good looking people get noticed.
3) I wonder if Jon was a pool hustler. I know it could be a far fetch, but its a fast and easy way to get money - if you needed it. He played pool with the KOA manager. Could it be possible that they entered a local bar (stuck out like a sore thumb) decided to make some quick cash and pissed-off the wrong people? To me this murder is not a robbery it was I want you dead, I will make sure you are dead, very aggressive killing. To rob someone I would think that you would shoot to kill and take all valuables. Honestly, how hard would it be to slip off the ring and watch? Not very. The fact they had multiple gun shot wounds, the murderer was mad, maybe embarresed. The murderer wanted the last say and he got it.
I just know being 26 and going out and having fun, you get liquid courage involved, possibly embarresment.. Its not a pretty site.
4) Do we know if the potential suspect (the one they pulled over for DUI) did he have any family in LE. Was his wife related to anyone in LE? Possibly his family name has been in that community for generations. Trust me I am from a small town and its amazing what can be covered-up.
5) I honestly think that they were traveling via some sort of vechicle, it does not sound like hitchhikers.
