What took my hen and all eggs in nest

This evening when my husband got home he noticed some feathers near our turkey hens nest. We live in SW washington and we free ranger out birds. Normally at night they are locked up but out turkey hen hide her nest and went broody before we discovered the nest. She had 10 eggs and had been sitting for almost 2 weeks with no problems. When my husband went to investigate the feathers he discovered she was gone as well as all the eggs. There were not any shells and no blood. There was a feather trail leading down into our woods. He followed the trail and found a large piles of feathers but still no blood and no body. Anyone have an idea what kind of animal could have done this. Or does this sound human thief like? We thought of humans because non of our other chickens or turkeys were bothered and there were no animal signs or tracks. Help!!!

 

Just an update: bought a large live catch trap and bated it with eggs and marshmallows. Nothing. No animal signs. Nothing. Non of our other hens have been bothered. I'm beginning to think it was a human that took the hen with a fight that left done feathers and all the eggs. Still not sure. But the good news is I have 5 chicks that I hatched in my incubator to keep her line going. Miss my henny tho
