I have a friend that shot a wolf probably a little over 20 years ago about 10 miles past Rustic, CO, which is on the road outside Ft. Collins on the way to Walden. He was lion hunting and came across two wolves taking down a deer and managed to shoot one of them. He called DOW and asked if there were any wolves in CO., of course they said no, so he asked them to come by and see if what he shot wasn't a wolf. They took one look and said "yep, thats a wolf". We had been seeing wolf tracks for a couple of years in that country. We figured what was happening was there was this guy that had a "hospice" or shelter that took in 7/8 wolf hybrids from people that decided they didn't want them. You'd drive by his place and sometimes he'd have 4 or 5 and the next time you drove by his pen would be empty. No proof but we figured he was just turning them loose up there.
