We showed the pics to a wildlife officer and he pointed out how the cuts on the hind quarters and belly are very clean, not ragged and torn. The missing head is another concern - most predators won't bother with the head, it's too hard, doesn't contain much meat, and therefore consuming it uses more energy than it provides. And the gut pile was left more or less neatly in the grass, entact. Predators eat that first, it's soft, easy, and full of calories. Some indicators this might be a poaching. We've had a couple 4 pt'ers hanging around. I don't think the rib cage looks big enough to be one of those bucks but could be. On the other hand, we can't find a blood stain anywhere. If it was poached, where did they hang it and clean it? And if it was poached, it must have been by bow or crossbow because someone would have heard a gunshot. And it's about 400 yards from the nearest road so they would have had to haul the head and meat that far to a vehicle (unless they walked between our houses) and we couldn't find any footprints. Maybe a .22 at 2am would go unnoticed? I don't know.
