Question: When Josh is in the further looking for Dalton, what is the deal with the family that looks like mannequins and has the creepy smiles? Why does the one girl shoot the family? Is there any back story on it?

Chosen answer: It's implied that the girl went crazy and killed her family, but it's not really elaborated on. They're just some of the many spirits to be trapped in and haunt the Further, likely due to the violent nature of their deaths.
