I had a look at the house floor plan (yet again), and 2 things struck me that I had never really noticed before:
1) I hadn’t fully realized how much of the basement is essentially under the back and side lawns vs. Under the house. This can be seen by comparing the location of the spiral staircase of in the master bedroom and main floor (it’s at the very back left of the house) vs. The basement, where it appears in the middle of the house. So the whole pool and sauna area is essentially under the back lawn. The floor plan illustrates how isolated the pool area is from the rest of the house, and that the only access to the pool area is down the long hallway. Someone committing murder and/or hanging the bodies in that area would certainly expose themselves to not hearing if someone entered the house on the main floor. This points me to wondering about multiple assailants, perhaps with walkie talkie communications between them to warn the one(s) in the pool about someone approaching the house on the main floor.
2) Based on my previous examination of the floor plan I had concluded that the only exit points from the basement were through the garage; or up the internal stairways to the main floor. However, if you look closely at the floor plan there appears to be another entrance- an entrance/exit door beside the spiral staircase in the basement. I had previously missed that, and this would obviously be a relatively secluded place to access and exit the house - from the side yard and probably via an outdoor stairway dug to the basement. Often side yards are not well lit and are sheltered by vegetation, etc.
Does anyone else think that doorway is an external doorway? It looks that way to me, and I don’t recall anyone ever posting about it before.
