<modsnip> here is a podcast by Elder Jensen of the Mormon church. A lot of posters have said that JA became a Mormon so she could get close to TA..but if Elder Jensen is to be believed, it was TA who gave her a Book of Mormon and sent the Mormon missionaries her way. Who knows if JA would have known of Mormonism/Joseph Smith if TA had not sent the Mormon missionaries her way??

I will not put down Mormonism. I think each and every religion has something of value that can be viewed in human character.
I do not, however, think it has anything to do with the case other than JA started to read about it and go to the Church so she could get TA. That's it. She set her sites and went for it gangbusters. She was bored with Daryl and son and wanted to be with TA.
