Her mother unwittingly has already poked a hole in the Corfman lies.
Maybe. I remember when I was a child we didn't have phones in our bedrooms but we did have a hall phone with a long cord. I could bring the phone into my bedroom and close the door.
Someone would need to ask the mother if it was possible for her daughter to have done something like that or not. If not then the daughter's whole story falls apart.

Right.... like that girl had a phone in her bedroom back in those days. I doubt it.
You also might want to ask just WHY the mother came forward with that info about the phone.
