Of course, you are absolutely right, Cubby. But you have to admit, those publicly posted statements have given us insight (such as it is) into the dynamics of this family that we rarely, if ever, see on missing persons cases. They have also made it possible to see questionable details with regard to the timeline and most certainly, a possible motive.
IIRC, the comments on IS were not at all negative in the very beginning. I've already mentioned my pathetic memory, so hope someone else who was following there can back me up on this. But I recall the daughters initially pleading for help finding their father. It was a bit before it took a darker turn. In retrospect, I would guess that had a lot to do with F deciding to stay in the home and stake her claim. Seems it went downhill from there. Fast.
