Growing up and living in the Rockies, it seems there hunters all along the entire Rocky Mountain Range, from the north border to the south of the range. Except IME both colleges I have experience with students that were hunters are a minority. That said my husband is a hunter, previously avidly, and has a special knife he takes with him, but it's only for field dressing when necessary (along with a bone hack saw) and is A LOT smaller than the pictures of knives I see might have been used in this crime. Pictures I've seen are like the knife Sylvester Stallone used in Rambo, in my real life the very sharp knife my hunter uses here south of Idaho is 1/2 or 1/3 that size. And hunters don't kill with knives, just use them prepare the kill to transport home. I have a feeling the killer is deranged and not a hunter as hunters are much more compassionate to their kills. Imo of course.
