I am wondering if EG took the pic of the mystery couple smoking to try and set up a fall guy so she could report Lucas missing the next day - then she chickened out of it or decided it would be better to wait until later so as to hopefully let evidence be diminished.
If I was disposing of a body and also reporting said person missing, I would go into that thinking they could find the body at any time, even if I thought I did a good job hiding or waited long enough to report. It just bugs me because once he was reported missing, they would be looking for him and could find him at any time - whether by animal activity, smell, searches etc. If they found him right away the difference of whether he died on the 11th or 17th would be very obvious. UGHHH I get why we don't have more facts but I wish we had them! Or at least LE could say x, y and z things being reported are incorrect. I'm guessing she thought certain things out and had a story just in case of anything, but who knows. So frustrating.
