I just feel that they never made it home. Which leaves a huge area to cover for searching. Which is an impossible feat.The only corroboration I can think of, is supposedly, DM's mom said she thinks she heard the kids playing in the yard that morning? Do I have that right?
Not that it would be ironclad evidence anyway. It's worded in a way that gives her wiggle room if she needs it.
But we didn't hear her say that she engaged with them, face to face, for example.
