I took the still-shot, the one where the perp is looking directly into the camera, and enlarged it/zoomed-in to it.
That is all I did to it, and I used Irfanview.
I cannot get it any clearer than this, and of course, 'enlarging' it, messes up the pixels. But here it is.
(This looks like a "male", to me.)
I meant to also show this one.
It is the same still-shot, but it is not 'enlarged', as much.
(You will notice that, in the one that is 'enlarged' the most, the eyes then 'look like', they are closer together.)
In the one that is 'enlarged' the most, you can certainly get a better look at the "silver" strip across the helmet, though.
(At first, I thought that might just be how the light was shining on it.
However, it looks like it might be something more uniformed than that. That it might actually be something on the helmet.)
Some have mentioned that it looked like there might be something attached to the side of the helmet. Looking at this, it seems that it 'might' have something attached. Although I don't know what the thing is, exactly, if there is something attached to it.

This is what comes to my mind (and always has), in regard to the person who this gear belongs to:
1. They have an interest in these things.
(and more than likely already had this gear, before, they did this case.)
(and they like hi-tech stuff)
2. They have possibly been in the "military".
3. They possibly have an interest in, "sports".
(weight-lifting, martial arts, other)
Their body form is possibly, in good/very good shape. (defined muscles, etc.)
