if you trace her path, everything has been remodelled except the alley she was filmed in. The corner she turned, and the houses near the corner, all gone or remodelled. Kilroys, remodelled. 5N and buildings next to it, the back of all remodelled. Across from 5N which was fields, all have new apts and townhomes all the way up to the corner. The alley leading to House Bar, another place very near JRs that is one of my theories she ended up or was heading to, all remodelled. Both Kilroys and House Bar closed during the heat of her disappearance to open quietly back up months later.
For all general purposes, anywhere she might have gone IF she did leave JRs has been changed or torn down.
If her body had been hidden by construction somehow, covered in cement, IDK, it could have been moved long ago and removed during all of this construction. Not saying it's a conspiracy, because on the other hand, if the POIs did leave her hidden nearby, surely they would have found her during this extensive construction. Really, I can only see a local doing this, or the out of town guest. The other POIs may be smart, canny, whatever, but they
don't have the know how of this land, the search effort was extensive and covered miles and miles. The reward was enough to bring all these locals who knew the land out to look for her. The tweet from Runcible Spoon was/could have been a code. A three way code. Someone took her out of town, hours later tweeted DB, who then tweeted about corned beef to establish he was in town. But was his car in town?
