I am still stuck on the motorhome thing. IIRC the permits were requested in March. Just before shutdowns for Covid, not sure if that played a role in delaying things but maybe CD was thinking he could put a motor home up on the property for one of his kids and cover the burial site. Inspectors go out with an undercover FBI agent for permits. Sunken terrain, odor of decomp, etc that could have tipped them off. Aerial photography also supports their suspicions - warrant requested to bring in ground penetrating radar & cadaver dogs to look for remains (as they had always planned).
This whole motorhome idea appears to have come up after LVD was arrested & returned from Hawaii. Because from what I can figure, CD & LVD planned to not return to Idaho and live in Paradise sans children & responsibilities forever and the afterlife. Strange to want to have the motor home because he didn't appear to want to move LV into that home initially - couldn't because they were still hiding the fact they got married. When the kids realized for whatever reason, that there would not be 2 residences (ie: home & motorhome) they planned to move out by mid june?
speculations . . .
