We don't even know IF it changed or if it seemed to have, to what degree and to what significance. A statement was made fairly recently, by Deputy Penner, that they were working on some leads that came about from information that had been previously withheld. I tend to think that information was previously withheld by LE. Just Saturday, they interviewed IR for the first time since he retained counsel. DK and JM also went in that day for yet another interview. When DK and JM were asked questions for which they didn't know the answer, something ensued, and DK and JM stopped cooperating. So, SB didn't get any "new" information from DK and JM that he didn't previously have (IMO). Two days later SB announces that he has decided to name them suspects because (in his mind) they absolutely know where their son is. Klein, otoh, was seemingly pointing his finger at IR, yet IR through his attorney, refused to be interviewed by Klein and company. Now, for some reason, SB puts out there that IR has been pretty consistent. Why make that statement? To me it seems like the previously withheld information is contained in the polygraphs. That info might have come from the behavioral analysis of the interviews and polygraphs done by the FBI and just recently provided to SB. While it certainly might appear that DK and JM are true suspects, that might not be the case at all. Of further interest is Klein's comment regarding today's announcement.
