If I may interject re: the awkwardness of the movements? I am fairly convinced that this is a person wearing different layers of clothing to somehow hide their gender, shape, etc.
There is something about the hands and legs that looks as if there are other layers there. And the person doesn't look comfortable...they look as if their movements are limited by something; whether this is the weight and bulk of the backpack, the weapon tucked into the waistband, or (as I have done in the past when we lived in NM) wearing leggings under jeans because it was going to be cold while I was out at night...I don't know.
The movements are odd, the attitude towards the camera being there, and the very odd way of trying to cover it (after appearing to look for a key? among the pebbles)...not professional, but thinks he/she has checked off all the boxes of "knowing what I'm doing."
In my opinion, there was planning involved, but it got convoluted, the situation probably got out of hand, and we are now where we are still trying to figure this out.
Opinions galore.
