"During the initial check it was discovered that a neighbor residing at 11995 Mountain View Drive, identified as David Westerfield, was not home. Most all immediate neighbors were at home and contacted."
Most means not all.
I forget where the transcripts are but my memory says that this was asked of one of the officers that questioned Westerfield during the preliminary hearing. It was established that an officer was assigned to search all the houses within a certain area and that two of them went unsearched as of Monday. One empty and one Westerfields.
I believe that was brought up to show why they questioned him to begin with.
