I found myself studying different images of BG last night. With things seemingly at a stand still I was drawn back to the most important piece of evidence in the case, the images. Thinking, he's right there to be identified. As I looked over the images, and adjusted the size and brightness, I started viewing it as one would an optical illusion picture. I studied the images of BG for hours, and I made a few realizations I felt compelled to share as I don't believe I've seen this information previously. The first thing I eventually came to realize is that he is not wearing a hat or hoodie of any kind. His head is uncovered. He has hair, a fairly decent amount, that appears to be brown of some shade. He isn't wearing glasses of any kind.
The image that seems to contort the view of his head/face that people have long viewed as a hat of some sort is a shadow. If that shadow wasn't there I believe we would have a very clear view of his face, clear enough to be able to identify him with comparison photos. I can make out his left eye fairly clearly, his right eye is in the shadow. His face doesn't have a beard, possibly a bit of stubble on the chin.
Another thing I noticed was his legs. They look very skinny to me. His legs/walk resonate that of a driver to me. Someone whose legs get very little use and have atrophied a bit.
I am positive, beyond a shadow of a doubt, he isn't wearing a hat or hoodie, or glasses. He has a head of hair. It's difficulty to identify what color his hair is for certain. I was convinced it was light brown at first, bordering on hint of blonde almost, but in other brightnesses it looks closer to a greyish brown.
It's not earth shattering but something important nonetheless. I've seen so much discussion and debate on the hat. Hopefully people will get a better look at him when they know more of what they're seeing and not seeing.
