What's the point of asking them any hard questions, in the form of being sent to their home, if all that will happen is their attorneys will field the questions and counsel them on how to answer. It's preposterous and no doubt LE knows it.
LE has hard questions for them, for DB, it's not LE has hard questions about other people.
I don't understand what's so hard to understand about LE investigations. Can anyone name when another potential suspect demanded that they be questioned together with their boyfriend?
And I would bet even if they were innocent, most parents would be willing to go down to the police station whenever they were needed to, however many times it took, especially if they have two powerful attorneys by their side. That is if they really were innocent and really did want to find their baby. I would also bet for most parents, the sheer anguish of not knowing what horrific things their baby could possibly be going through, knowing that every minute wasted is another minute their baby could be going through unspeakable things, would override their own needs and concerns about themselves.
