Absolutely if this goes to trial BFF would testify as to what exactly KK told her. Whatever KK said directly to BFF is not hearsay....RSBM for focus...
I think BFF may be feeling some real remorse for knowing much more than the R’s are revealing.
And maybe she’s afraid of KK...
Wouldnt BFF be a hugely important material witness against KK and PF?
The R's do not have an attorney-client privilege to any party in the case. They do have an employer-employee issue. They are mature professional people and they determined that to call the FBI was the best course of action. All the R's could really offer was to point the FBI at their employee/BFF.
If the R's, professionals who don't follow every true crime story in the news, just happened to notice a blip in the headlines about some out-of-state missing woman, a mention of a "Patrick", and a phone ping in Gooding, ID - that led them to call the FBI... why didn't BFF call them immediately herself? She knew more than the R's and could have called police Dec 10 or whenever she saw the news - but it does not appear that she did. Why not? Maybe you are right, she fears KK somehow.
