I am the one that speculated maybe he just wanted to dispose of her over state lines. I think it is a stupid move because I would think that could bring some federal charges but he is not the brightest apparently and I thought maybe figured over state lines would make it harder to investigate and even fit with his false story? Also no one was looking in Arkansas they were looking in mainly the Houston area of Texas.
I think Lillymac's point about the route and him being familiar with it from having traveled it to see relatives previously, is that it is not the closest or shortest route to St. Louis or most logical one from Houston, so why that route and why possibly familiar with it?
The Louisiana remark was about it being closer if his purpose was over state lines.
So kind of three different points going on and none of it has to do with her having family in Louisiana, just him looking for a disposal site, maybe over state lines, and I was wondering why he chose the route he did and AR, and whether any state was closer if he simply wanted it to be across a state line.
Not sure if that clarifies either but I tried
