Okay so, the idea that this is him in the "brain damage" video was bugging me. Technically, there are 4 people in this room. The kid punching the punching bag with his head (typical teen boy stuff), the kid sitting in the corner, the kid who walks in later (and for the record, after I cleaned it up, that kid is YOUNG, maybe 10-12 years old, tops) and the person taking the video.
So, here's a still from that video, with contrast adjusted and a few other magic tricks to remove shadows

I realize this video was uploaded about 16 months ago, but if you compare what he's wearing in this pic to what he was wearing at the images of him at the vigil, this pretty much settles it for me.
