Wudge, it takes a hell of a lot of imagination to come up with such a convoluted plot. There is ZERO evidence that this guy did anything wrong. Bodies are almost always found like this - someone fishing, someone hunting, someone hiking, someone taking a leak, someone walking a dog, kids out playing, I know of very few cases where LE is actively searching for a missing person and find the body. They're not little laid out skeletons, they look like rocks and branched and sticks and garbage.
The most likely explanation, and the simplest, is that this guy and his co-worker are sitting in the truck yakking, maybe about this case, Kronk goes in past the treeline to pee, sees something and then thinks (like all of us would, "nah, that can't be what I think it is" goes about his day and then when he has time to think about it, feels that maybe he should call it in.
The way people are trashing this poor guy and ruining his reputation, I bet he rues the day he ever got involved in this case. Imagine you're Kronk and everyone is now suspicious of you for doing nothing more than a citizen's obligation to help LE.
