I felt that way forever, but now I just don’t know. What if it was someone they did know in passing (janitor, softball coach from a different school district, something along those lines) but they did not know his name? The other possibility (someone mentioned BG could have had nylon stalking over his face) is that BG was disguised well enough the girls would not recognize him.
I believe that Libby’s cell phone stopped recording (it was also mentioned that DG had tried calling Libby & that may have forced the recording to stop), before they realized who BG was. Therefore, no name would be on that recording.
