I'm not one to jump to conclusions one way or another about things like this, but there is enough skepticism being brought up to make you wonder. The only hard evidence we have to go on is the pictures. The nighttime picture seems to be from a cell phone, so the quality isn't great. The first thing that stands out to me is that in the nighttime picture, the deer's body is angled towards the camera and his head is twisted around to face the camera. If the deer was shot at night and found the next morning and the nighttime picture was taken the night after that, then the deer had been dead for over 24 hours. Seems to me that with rigor mortis all set in, you wouldn't be able to twist a deer's head back around like that because he would be too stiff, especially a buck with as big of a neck as that. Comparing the pictures, the deer does seem to have been dead longer in the day time picture, but who knows. I wish the quality of the night picture was better and showed more of the deer.
