I'm trying to identify a true crime case that I watched on a daytime talk show years ago (I originally thought it was Dr. Phil, but it could have been Montel Williams, Maury, or a similar show with a male host).
Here's what I remember:
It was probably a case from the 1990s.
The missing children were a teenage daughter and her younger brother.
They disappeared at the same time, I believe, while they were with their father.
Pretty sure this was in Missouri but might have been Arkansas/Oklahoma area.
Their parents were divorced or divorcing.
The mother was convinced from the beginning that the father had killed the children and spent years trying to prove it.
The father denied any involvement for many years.
Several years later, I think the father confessed (or admitted what happened), the children's bodies were found, and he went to prison.
I also have a vague memory that there was some connection to a bookstore, but I can't remember if it involved the family, the investigation, or something else...maybe the mom worked at a bookstore?
I realize I may be mixing one or two details from different cases, but I'm hoping someone recognizes the story. Does this sound familiar to anyone?
