My faith in LE is strong (local, state and federal). I have professional experience with LE in this region (not Sullivan County) and can attest to their desire to find truth. Of course, this is a generalized statement based on personal experience but I feel comfortable speaking to the abilities of LE in the region.
IMO, the residence(s) on Sandy Pointe are part of their investigation. After all, MB was staying there after leaving TBjr's trailer so, logic dictates EB would have been with her at that time (mid-late December seems to be the confirmed time frame for last sighting of EB).
I realize HW and his family are managing this situation while safely positioned behind lawyers. Smart move, by the way, since a substantial amount of assets are on the line. LE is, most likely, battling road blocks from their lawyers every step of the way. Of course, this is an assumption on my part. Time will tell if it turns out to be truth.
Either way, it's only a matter of time before LE gains access to properties owned by HW and/or his family. Personally, I hope the W family freely offers that access and invites LE to search. If they do that and nothing is found, the focus will return to AB and WM as MB's cohorts. But, for now, HW (and family) will obviously remain on the radar simply because there is no reason to exclude them from the investigation.
IMO
