My two cents regarding GP’s Instagram account & the final Instagram post:
I believe they took the photos while in Ogden and GP planned to use them for a Halloween post at the appropriate time, because of the colors and it would make a cute Instagram holiday moment. But IMO, BL posted them to GP’s Instagram prematurely in an attempt to make it appear GP was posting.
Also, I believe that BL disabled GP’s Instagram account briefly, but put it back online on the advice of those around him, because removing it would be “suspicious,” might prove he had access to her account, and leaving it active might suggest she was still “with us.” As always, MOO
