Hmm. I'm one of the three people so far who voted 'no'.
His comment about making sure she'd never be found makes me think he's given this alot of thought and so far she's nowhere to be found... I really hope I'm wrong but I have a bad feeling about this case. He's probably telling the kids mom has run off with another man and after a while they'll start to believe him.
I can't belive LE can't force the kids to talk to them, with someone great with kids in this type of situation of course. They really do hold the keys to the truth.
