Looks like a wig. On top of a skinhead?
Color me crazy, but he looks more like he has an Indonesian or Phillipino coloring.
Doesn’t look like he’s carrying a lot of weaponry. One, maybe two handguns.
It took so long for the first responders to get there, that his victims probably bled out. One 9mm with 10 to 15 hp rounds could do that, if the shooter made every round hit a vital organ. Shooter would have to be an expert for that.
Hair definitely looks like a wig.
Skin color is not lily white.
Looks more olive skinned to me...
