Yenno that guy who's face split while diving? well that's gross!?

What was his name btw? This was long time ago but i felt like sharing now :p Ok, so anywho how does that even happen? How can you split your face that much? I mean, did the guy's face hit the stone ledge? Well it must've been pretty hard because it caused A LOT of damage. That's pretty disgusting how his face was like cut in half. DId the bones break or something? Like what actually happened to the skeleton of the face? And does anyone have any idea on how your actually supposed to fix that? ...how else can your face split?
