The neck wound could be a bullet fragment exit wound. I knew a Marine that was shot in the face when landing on Tarawa in WWII. Many years later he suddenly went partially deaf and it was a bullet fragment that had moved through the tissue to press against an ear nerve.

So apparently Vince decided to taze himself before eating a bullet. Or maybe the other way around - about as logical.
