Mountain Top Murders

Your Nana was always a bit estranged from the family, but you tried your best to stay connected to her. I mean after all, she’s quite old, and she shouldn’t have to spend her days in solitude. You do really worry about her, but she insists that she's fine in her mountain cabin by herself. It was always an hourly phone call that was your little bonding time, but nearly a month has passed since your last contact with her. You decide it's time to take a visit up to check on dear old Nana Hannah. It takes you all day to get directions and now that night has fallen, you only make out the cabin by the cracks that shine through her fencing from your headlights. You peak through a broken window pane to see red marks down at the end of the hall. Calling out, there is no answer. Did someone break into the cabin? Is that slashes of blood on the wall? What happened to Nana Hannah?
