Thank you, that is my right, but the suspects left. I think of the reflectors on the backpack. Those are very bright. So my first thought was a reflective something on the wall or near the wall. You can see at one point what might look like movement is just seeing the bright through a piece of foliage. But then on several viewings, I suspect that is the backpack reflector and the suspect changed their position. I will get on my computer later and see if what I thought I saw can be captured.
Note to self. At .07 looks like a shoulder drop.
