This is simply my opinion based on videos, photos and news reports.
Been studying the area where Gabby's body was located across the creek. Her mother stated it was about a 5 minute walk to where Gabby's van was located in the Red, White and Bethune video. It's in an area where folks may hike but are not likely to camp there. However, her stepfather said there was a possible circle of stones for a firepit and a flat area where a tent may have been set up.
IMHOO I feel BL chose this isolated location with a specific intention in mind. He made sure it had a view of the mountains so Gabby wouldn't be suspcious of his intentions. Further, I think when he flew home to FL, he returned knowing he would kill her. Yes, I do believe he set their camp in that particular spot so he could murder Gabby. It's just a working theory I have; nothing more.
Also, in full length photos of BL, I notice a distinct black line that oddly appears to outline his silhouette. It is not due to filters or enhancements. It is because his body hair is thick and black. His legs are quite hairy. It's very distinctive.
Some photos of him show an unkept black mustache as it begins to cover his lips. If he intends to hide in plain sight, he needs to shave those legs and possibly his arms as well. I'm not fond of him or I'd post a screen shot but not on Gabby's threads. I will not put his picture here.
