They were looking for live persons the previous night with no expectation of coming across a crime scene so I expect that there wasn't much said other than assigning areas to search.One thing that bothers me about the entire larger potential crime scene as well as where Abby and Libby were found is the previous night's search and up until discovery. It seems logical that some evidence would have been accidentally destroyed because of the volunteers searching and walking through and over it. I'm unclear how many participated in both days' searches or what LE instructions to them were. MOO
The next day was handled differently.
