Camera captured the face and outfit of the shooter, looks to be clad in black, with some type of patch/badge on the right shoulder of the shooter. Color is sketchy on YouTube, but shooter appeared to be somewhat darker in complexion that those he shot, but could be that the shadows and motion of the camera as it fell distorted this a bit. I'm sure someone with better equipment than trying to freeze-frame from YouTube can get a clear picture of the perp.
That being said, prayers for all those who were shot.
