I don't know if Greta's interview has anything to do with the arrest. Greta thinks so, therefore I tend to believe Greta at this point.
Maggie, what was the exact quote of the message Joran sent that night on Yahoo Messengr (again!)?
Could there be something he said when Beth and Greta were there and the camera was off, when they surprised him by showing up unannounced? Are we certain that she is only talking about the exclusive on-camera she did with wife and hubby? Just wondering...
There could have been something about that/those phone calls Paulus was taken while Greta was there in the home. Something about the phone calls and the presence of Greta possibly could have put Paulus in the very uncomfortable, sweaty, handwringing mood.
