The guys that say that never have picture evidence of a body and never file a report with the game department either. I'm not saying that it doesn't happen, but I'm local to the general area and I can tell you 95% of the people saying that are full of shit.
I know 2 guys who have and WSP just forwarded to tribal police who did jack shit. The only case that I’m aware of that tribal police actually did anything was the bed full of bald eagles that a Yakima tribal member killed.
