I have a gut feeling they may have to go back prior to the day Codi was reported missing to get to the bottom of it all.
They will likely do that as a matter of course. Whenever I led an investigation, officers were always briefed to ask potential witnesses questions that pertained not just to the time given but also the 48 hours previously, especially when asking POI’s because it relaxes them into the narrative and they will happily talk freely as they have nothing to hide but one of two things generally happen as you get to the pertinent timeline where events became challenging:
1. They start to relay events in a different way and their speech itself changes and they become obviously uncomfortable and display NVC’s ( non verbal communications) which show forms of deceit in the answers that they give.
OR
2. They are uncomfortable from the start and find it difficult when questions are asked, ( often one question can be posed in half a dozen different ways) to maintain the same answer for the question (irrespective of how many times and different ways a question is asked, if telling the truth, your answer will be consistent but when lying, it is difficult to give the same answer to a question posed in a few different ways because they are trying to remember the lie and often are so consumed with that , they overlook that it’s the same question but worded differently and they slip up).
So by starting your interview with a POI, it’s important to go back, sometimes as far as a week or more depending upon the circumstances, so that they relax whilst talking about mundane but true daily occurrences but once they have to start to lie when answering questions, their whole demeanour changes .
An absolute classic portrayal of this change in behaviour in a POI when talking about truths and then having to switch to lies and the NVC’s becoming very apparent is the interview of Colonel Russell Williams, a high ranking officer , Commander of CFB TRENTON, Canadian Armed Forces, sentenced to life imprisonment for numerous first degree Rapes and two murders - all female. Take a look on YT. It’s a fascinating and very skilful interview by the Investigator.
That leaves one thing.... someone he trusted, and either lived in the house (dad), or visited, and was very familiar to him (mom), walked out with him. Keep in mind his parents are both POIs which makes my 2 points above extremely plausible. At least I think they are still both POIs. I haven't kept up and just sat back down to my puter.
