No info at all for this but daaaaamn.. look at his skull. It opened up just like a delicate little flower and shit. Okay, maybe not so delicate but it did open up. No info on who he was or why he was shot, but most of these kinds of videos have the same backstory. Dude was in a gang. Rival gang captured him because he did something stupid. Rival gang kills him and films it as a warning to others. The end.
