If one of my kids was missing I would be a complete basket case. The mom's behavior just doesn't seem normal given the circumstances.
I agree with you on all counts.
From my understanding, the most dangerous person in a child’s life can often be the unwed mother’s boyfriend.
He has two older children. He didn’t marry their mother.
He’s not married to Deborah, yet. And being “engaged” doesn’t count. For all practical purposes anyone can get married within a few weeks time, if they feel compelled to do so. A wedding is not necessary, when there are three children that need the stability of a marriage as a foundation, especially because they were all born out of wedlock.
I’d look at the father of the child, who is also the boyfriend, in this case.
