In my experience, when a case goes cold and info is scarce, the theories get wilder and more far-fetched.
I cannot help but think of the Closs case. LE was hampered by the fact that JP had no prior association with JC. He was a loner, living "off the grid," outside Barron County. I wonder if something similar is true of BG. No prior association with the girls. No cell phone or social media trail. Maybe BG's a loner and, though he has a past connection with Delphi, now lives outside the general area. If so, LE may not even be close to IDing him.
@sumzero, after listening and re-listening to the Apr. 22nd PC, it is difficult -- no,
impossible -- for me to believe that the suspect is anything
but a local. Local to the town of Delphi. Local to know the Monon High Bridge trail. Local to know who was home and who was "snow-birding" (in the nearby houses). Local to know the sneakiest-peekiest way to be on the bridge and to get the best view. Local to... (
should I write this?)...
lie to LE. Local, local, local. But! I "get" why you mentioned the JC case in WI, and JP (who admitted that he saw her and planned to "take" her [his exact word;
creepy]). Oh -- did I say "local to have family/friends in Delphi"? And I also meant to say "local", as in having a "local workplace/place to volunteer
in Delphi".

Now, having said all of that, of course, LE will oust him from the middle of some underground cavern 5 states away...
Well... up until at least Feb. 13, 2017, IMO he
was local. And -- this, based on the PC of April 22nd (scarcely a month ago) -- I would say that the suspect still
is local (though he may commute from time to time; just
think of the "heat" he's feeling... or...
is he? Maybe he's just hit "delete" on his conscience? But that's a whole
other topic!).
All just MOO and pure speculation.
