Hi Scarlett!
I’m not familiar with the names of the counties and towns in Indiana and their proximity to Delphi in the article you linked, but my thoughts on the posts by you and BoP have taken me here...
IF DN turns out to be involved in the Abby/Libby case...
IF DN could be identified as being in or around Delphi ON February 13, it would show he had the opportunity.
IF DN could be identified as being in or around Delphi PRIOR to February 13, it would show he had some familiarity with the area and may have known about the MHB/trail system.
Since it has been published in MSM and mentioned multiple times in these threads that DN liked being in the woods, hiking, outdoors activities, it would be a logical train of thought to connect the dots that if he could be shown to have been in the area previously, and possibly had knowledge of the MHB and the trail system, even if he wasn’t working in the area in mid-February 2017, he could have traveled to Delphi to do some hiking, by driving a borrowed vehicle, by bus or by hitchhiking.
I’m still not convinced DN is BG, but I’m not ready to rule him out either. Finding information on how close he has been to Delphi and when he was there (near Delphi) would be helpful. AFAIK, DN is still unaccounted for on February 13,2017.
