Wow, there's a whole boatload of speculation going on here.
For me, I'm a bit more cautious moving forward. I see danger in attempting to deduce too much from what I see, and read.
From what I know, there is no POI in this case. It is a missing/endangered persons case.
I can easily speculate too, like, the items removed from that home were for SAR canines to get scent from, to aid in searching.
I can also wonder, if such atrocities occurred in that home as I am reading some speculate on here, how is it that there are folks living there again? This alone makes no sense to me.
I say go easy folks, yeah, we all know what we know, and think what we think, but what good does it do to play judge, jury, and executioner, when indeed, at this point, we do not have the facts?
