Yes and following on from day 1 like yourself I don't think we are any further in knowing what happened. Of course we can speculate and hypothesis until the cows come home but our guesses are as good as what's on the other side of a black hole
I do think they were harmed though despite the terrain being so unforgiving. It's just observation over the years on other cases and seeing the same patterns emerge like revelations of cps involvement , drug use , DV with false imprisonment as a stand out . It wasn't a safe home by any stretch especially if teachers and family were concerned
But was the target mbm alone , it still remains to be seen and I hope this case does have closure for the family
