The position of the entry wound was unusual enough to raise the question. (

The timeline I believe fits
best (now even more so, after this new information):
-
Aug 27 - After being seen together at Merry Piglets, they park the van at Spread Creek (where the YouTubers saw it at 6pm) and set up camp
-
Aug 28 - They camp at Spread Creek
-
Aug 29 - According to hunters, the van was still at Spread Creek. Gabby had wanted to see her friend Rose for Rose's birthday (on the 29th), and after the recent events in Moab and Jackson, I suspect Brian was not on board with that. Perhaps they were still arguing. Perhaps she had bruises he didn't want anyone else to see. Perhaps he just wanted to isolate Gabby as long as he could. So he did what he'd initially done in Moab and took off without her. I suspect that he left her the van (having learned that lesson from Moab) but took the keys with him so she was stuck there, alone, with no cell phone signal. He spent the day hiking and eventually hitchhiked his way back toward the campground -BUT- knowing that Gabby was likely to be upset and not wanting any strangers to ask questions about why, he didn't let the woman who gave him a ride take him all the way to Spread Creek. When he got back, Gabby would have been (justifiably) upset about his desertion and about missing Rose's birthday, and THAT's when a fight ensued. It would line up perfectly with a frantic call back home and if Brian left the Tetons that evening, it'd place him getting back to Florida on the morning of the 1st, which aligns with the traffic cams there.
I do
not believe BL would have stuck around Tetons for
days after GP died, especially at the same campsite, with her body still lying
right there, exposed to the elements. I believe he immediately went into "flight" mode and would want to get as far away as possible, which would place her TOD on the 29th.
