Spear rebounds into diver's head

Glad to hear he's OK. I saw this on Yahoo news this morning also.
I'm trying to get a mental picture of how this happened. He must have been using a shorter gun and pulled the gun stock back behind him while looking into a hole, placing the tip of the spear near his ear or somewhere? This way the spear could have deflected off a rock. I can't see how a shaft could bounce back, turn 180 degrees and hit him.

There was a follow-up interview with him in this morning's local paper. He said it was a complete rebound. Maybe it didn't turn 180 degrees. Looking at the image you can see the corrugations - it's just a length of construction steel and not a commercial spear. It could be that what lodged in his head was the tail end after it bent and flicked back.

Wow. I'm not a spaer-fisher. Does a spear actually generate enforce force to penetrate a skull?

Definitely.
