There was a massive search for a missing pregnant woman in the town next to me 12 years ago. Of course the story was the only thing being talked about. I remember having chills go down my spine when I learned that she was a jw. The reason being is that I wondered if she was really missing or if she took off. As it turned out, she was lured into being murdered by a crazy woman who wanted her baby. The story made national news.

Whether Whitney was abducted or just took off, I hope she's found safe and sound. No matter what the situation, the poor kid is in trouble.
