4x17 - The Dead Files

Amy and Steve revisit a home that is haunted by an axeman and an entity he controls called "The Doll", as well as numerous other entities believed to have previously lived on the land when it was a Poor Farm. The mother of the current family initially called The Dead Files team because her disabled son was being harassed by paranormal activity. Next, Amy and Steve return to what is apparently Seattle's oldest restaurant. A former saloon and brothel, one of the entities believed to be residing there is bar manager and former wrestler Otto Hink. The original building was a hotel that burned down during the Great Seattle Fire.
