Importantly, LE does not have the physical bodies to search each & every area and that is why it is essential for Chad+ to do the leg work for them.
I believe LE has sufficient evidence at this point, however any additional found would be icing on the cake. :twocents:
If TS inserts himself into searches that is a good thing because searchers talk to one another and if he is involved, it is possible he may slip up and say something. Importantly, he must not be allowed to search ANY areas alone ... LE is depending on receiving any tips of anything found during searches and knowing each area that is searched and whether or not any evidence is uncovered.
What we seriously have to remind ourselves is,"Who would have motive for this to be committed and for her body NOT to be found?" :waitasec:
