If Chad and Lori were meeting in the temple, their attendance could be verified. A couple of years ago I had a family member in Arizona (long story...also a websleuths thread, ironically) who ran away and hid with her infant son and her family tried to frame her ex's family to say that he had murdered her and was hiding her son somewhere. We honestly believed the story initially until the threads and lies started to unravel. I was surprised in reading the police case file documents later to see that she had tried to use temple attendance at the Gilbert temple as an alibi. The police reports showed that LE went to church authorities and was able to verify that she used her temple recommend, but video files from the parking lot did not back up the length of time she said she spent there. Sooooo.....if Chad and Lori were attending the temple together, assuming they were using their own recommends in their own names (and not stolen ones which someone referred to earlier which is, in theory, possible), the dates they attended could be verified by barcode scan. This would back up Melanie's story so that it wouldn't be just hearsay.
