You never know what's going on behind closed doors. There could be years of abuse and controlling behavior by the husband. Or for all we know, the mother could have been the one that harmed the girl (although that's doubtful). Whatever the situation, I don't know how they thought this was going to play out. I'm surprised that they even admitted it had been over 3 weeks since they saw the daughter and I guess Thanksgiving was just the two of them because how would they explain to family or friends where Madalina was.At this point I feel like not enough is publicly known to have any real bearing on mom’s mental fitness, but seeing as though she chose not to report her child missing and that she’s been arrested without being able to produce evidence of where her child might be, she’s definitely not acting like a mother of sound mind IMO
The mother moved here around 2016 and they bought that house in 2017. My guess would be that she doesn't have many, if any, friends. None of the neighbors that I saw interviewed seemed to really know them. Between local LE and the FBI, they'll get that woman talking soon. She has nothing to lose at this point.
