I`ve had same experience with deer being curious and showing up shortly after I had downed a coyote.
The coyote / deer has happened to me too. Shooting seems to make them nervous but curious. Also last time in Alaska, I dropped a bull moose. Just as I got my hands into the mooses guts, I looked up and about 200 yds away stood a very nice caribou watching me. I rinsed my hands picked up my rifle and then had two big animals to clean and debone. I won't make that mistake again. I know the caribou had to have heard my two shots at the moose
