What you say would seem to indicate that she has other knowledge that is not public. I've suspected this for some time: that she knows things that happened since before her first trip home. That's the kind of person I think she is.
I know she is irritating to some, with that nasally accent. Nevertheless, she's a lioness about her child and for that I will ALWAYS respect her. That's what 'mother' is and does.
I just don't get the whole 'in love with a blond, blue-eyed boy' thing. I don't know what to make of that.
And I still maintain: they all know each other on that pathetic tourist-eating mantrap of an island. That makes them all complicit, in my book.
I take what Beth says with a grain of salt. I think she wouldn't have a problem exagerrating something or denying something else if she thought it would help implicate those she wants to see convicted--sort of like an over-zealous prosecutor. It is good in some ways, but it also blinds her to other possibilities.
I've heard that she refuses to hand over Natalee's cell phone and she refuses to hand over her camera to investigators. That is very odd in my opinion.
