I'm not convinced DC is remaining quiet out of loyalty to CP. She, obviously, knew Madalina was missing and did not report it until forced to do so (and that's a crime she should absolutely have been charged with). CP did/didn't do the same and should also have been charged (and he was).
So the question is, obviously, why did neither call police and/or school and/or ask a neighbor to call, etc.? And the more important question is where is Madalina?
There have been many theories proposed and discussed here, but aside from Madalina still being missing (AFAWK), we have ZERO LE-verified evidence to assert any opinion/theory is more correct than another. We have ZERO LE-verified evidence to assert one parent is more to blame than the other. Both are hindering the investigation by remaining silent (AFAWK). We have ZERO LE-verified evidence of abuse (neglect is abuse) from either parent or from one spouse towards the other.
IMO, speculating is different than having drawn a final conclusion regarding anyone or anything (except LE stating that Madalina is still missing and one or both parents are not being helpful in locating her) with ZERO concrete evidence to backup flat out accusations towards one (or even both) having harmed/killed/hidden her. Is it likely that at least one of the parents knows exactly what happened and exactly where she is? Absolutely. Do we have hard LE-verified evidence about which parent did what and/or which parent has knowledge regarding Madalina's location (or if both know what happened and both know where she is)? No.
In fact, LE is still asking for fliers to be posted, etc. At the time of this post, LE hasn't announced their belief that Madalina is deceased, nor have they charged anyone with abuse or kidnapping or murder. Of course LE knows much more than we do...which is why it perplexes me that ANY of us can point a finger and accuse either parent of having abused and/or killed Madalina. Right now, we just simply do not know.

Could DC have been abusive and controlling towards CP? Towards Madalina? Yes.
Could both CP and DC have been abusive and controlling towards one another? Yes.
Could both CP and DC have been abusive and controlling towards Madalina? Yes.
Could CP be guilty of harming and disposing of Madalina on his own? Yes.
Could DC be guilty of harming and disposing of Madalina on her own? Yes.
Could CP's trip have been undertaken to carry out harming and/or disposing of Madalina? Yes.
Could CP's trip have been completely innocent and coincidental? Yes.
Could DC be remaining quiet, because she truly doesn't know what happened and/or where Madalina is? Yes.
Could CP be remaining quiet, because he truly doesn't know what happened and/or where Madalina is? Yes.
Could CP be remaining quiet because he's been advised to do so by legal counsel? Yes.
Could DC be remaining quiet because she's been advised to do so by legal counsel? Yes.
Could DC be remaining quiet because she knows Madalina is safe and feels her silence continues to keep Madalina safe? Yes.
Could CP be remaining quiet because he knows Madalina is safe and feels his silence continues to keep Madalina safe? Yes.
Could either be remaining silent because they are hiding Madalina from the other out of spite? Yes.
Could either be remaining silent because they truly loved Madalina and the idea of something having happened to her (regardless who may have caused her harm and/or to disappear) leaves him/her/both feeling they have nothing left to lose and are despondent and/or stuck in a traumatic 'frozen' response? Yes.
Could a cultish group/beliefs/organization be involved in some way(s)? Yes.
We ALL want Madalina to be alive and safe. We know something has happened to her. We are all free to speculate and form opinions. I, personally, do NOT believe there is enough LE-verified information (as of this post) to draw a conclusion about what happened to Madalina and/or whom is responsible and/or has knowledge of it...and definitely not to make accusations of abuse and/or murder. JMOO.
