My theory: Beth rented car and used Jen not wanting to drive alone as an excuse to go on short holiday. JW and Beth met their boyfriends at said city. Four people were at Frosty Mug.
Forget the whole "train" idea. Never part of plan. Cover lie.
Now either JW dropped off Beth at restaurant where Beth was going to meet someone and then she disappeared with/caused by that person
or
That's a lie and JW, RR, and possibly mysterious "other person" are involved in foul play.
Plausible?
I have read that other person is RR's brother. I do not know if that is fact.
Time for JW and RR to tell the damn truth!
The more lies that come from these two the further they dig themselves into a hole.
I hope LE finds some info to investigate this as foul play soon, if they have not already and just haven't made a public announcement they are now investigating Beths disappearance as foul play.
I HATE saying that, but I see the other options as extremely slim.
I agree Cubby. Doesn't look good.
