I saw the show too. What made my eyebrows raise up was when they said that when the wife was missing for a few days, her family was very concerned because she hadn't shown up to celebrate her mother's birthday---something she was very diligent about and always did every year.
The marriage thing was odd too, seeing as how she yoked up wit an unbeliever, as much as they insisted that her religion was her life.
They said that the husband had taken her WTS literature, which she always carried with her wherever she went----and put it in the garage to make room for her body in the trunk.
A lot of things didn't add up for those of us who know how a JW thinks.
