My thoughts on the timing of the search:
Apart from any other material evidence or interviews with LE of which we may not all know (including neighbor's recollection of bonfires), we have the State of Idaho. Before March, knowledge of the search location is possible considering the presence of the FBI Mobile Unit that remained behind RPD for what seemed an eternity. However, Idaho ground was frozen and would have been difficult to search and sift through with chunks of ice and frozen dirt on scene. Second, we have COVID-19. We've seen the LEOs and Idaho justice system follow protocol set by the State in all aspects of the other aspects of this case. According to
Stages of Reopening, Idaho Governor allowed Stage Three on May 30 which included the allowance of gatherings of people 10-50. There were around 50 people on site these last two days. The State could not conduct a search before May 30 according to its own legal statement. I'm sure if life were in danger exceptions could be argued, but it appears to me that knowledge of the location was known for months. Bravo to LE/FBI for keeping that tight-lipped for so long waiting this out, especially with the public outcry and repeated delays in the ongoing criminal case.
