Wow. This case is on my mind all the time. Every now and then when I travel I have to pass the original Ohio search area and I just have to say a prayer.
There very well may be no connection but it is good the police are checking. How could they not?
On the plus side for this theory it would make a little sense of something that always stumped me. Police were able to track JS's movements during the time period they were most closely focused on. He drove from Morenci area down to Ohio and at some point briefly got on the turnpike. But I am pretty sure from the timeline they narrowed down they didn't think he stopped very long. They were searching near the Delta, Swanton, and Holland areas, and because his stop was so brief I think they were looking for bodies that were not well concealed. Yet they came up empty. Some of us wondered if somehow he had actually removed them from his home earlier and was just doing a nervous drive-by to see if he had been spotted or if there was any police activity in his 'spot.'
Now I have to think about the possibility of a handoff of a box near a turnpike stop or something. Incidentally, Missoula is right on I-90 as well. He was a trucker, could he have asked a trucker friend to make a box disappear somewhere, no questons asked?
I'm going to have to read the old threads again, and find timelines and stuff.
