Unexpected guest

This story happened a long time ago. Parents and their three children were living in a quiet village near the forest. They were happy and lead a merry life until one dreadful day.
One Friday evening they gathered together for a supper. By the way, it was their family tradition to spend time in the family circle every day.
As it always has been, parents and children sat down to eat after a hard day. Mother had cooked many tasty dishes, so they just enjoyed the meals and communicated with one another.
Suddenly someone knocked on their door.  It was very unexpected as it was deep night outside and no one had come so late before. It turned out that their guest was a stocky man with a big bushy beard and very arch look. He explained that he got lost and all he needed was a place to stay for a night.
Family kindly agreed to help him and invited to join the dinner.
Nobody thought he was strange or suspicious exept the smallest daughter who was terrified of his shifty eyes. Her hands were shaking so much that she dropped her fork under the table. When she leaned down to lift the fork, she saw that the man had hooves instead of feet. She quickly became straight and all she saw were her dead relatives and blood writting on the wall: "Your fork saved you"

You can thought that it is myth but how to deal with hoof prints which were found near the house?
