Sometimes you get the croc, and sometimes the croc gets you. We'll never know what actually happened, but I'd suspect foul play. An experienced pro hunter would already be well aware of his place in the food chain & not to turn his back on danger-infested waters, or go wading in it alone.
I'll put my money on someone "helping" to turn him into lizard food. Maybe it was one of those anti-hunter a$$hats such as those posting their stupid comments.
