Thanks!
I have mixed feelings about the moved bodies theory. It is, to me, the most fascinating "unknown" about that night. The supporting evidence is the very sizable pool of blood outside the front door. How did that get there?
The only other person whose blood that could be would be Voytek, since he went out the front door, but that much blood would indicate that he sat there in the front doorway for a while before eventually making it out to the lawn.
