I'm finding it hard to get past the fact the Jen was an active Catholic and Sunday School teacher, and neither GR nor CC thought to mention that in any infos or profiles that were released.
I mean, if I were trying to get info on a missing person, that's among the most pertinent questions I would ask: did she attend church? was she active in the community? Was she working or had she had a job recently??
But the church thing seems to me most crucial. For instance, if one was seriously considering the proposed theory that she had decided to "get away" for a little while to think, she might have gone to a monastery (I'm thinking of one over between Binghamton and the Catskills -- they make good wine there, but not sure if laypeople can "retreat" there).
Also, as a Sunday School teacher, I think she'd have been going to confession and mass regularly. She may have perhaps gone to counseling with her priest. Anything said in confession or counseling could not be shared, of course, but an interview with her priest could have allowed him to give a general impression of her state of mind in the weeks prior to her going missing, if she was depressed, or afraid, or perhaps anticipating a big change in her life.
But nothing was said at all about her being religous. We heard about her likes and dislikes with regard to condiments and coffee, but nothing about one of the most important areas of her life that could be crucial to locating her.
In my mind, that's paramount to being an accessory after the fact.
