Thanks, so it's not a direct statement from LE.
Since they have clearly said they are not releasing any information whatsoever, it is obvious they would not come up with that quote, it makes no sense whatsoever to think they did.
Probably the FOX reporter asked these questions, and got the answer "We cannot tell you that sir", as in, we told you previously we are not sharing any information whatsoever about this case nor the search. IMO
This then gets interpretated as they are unaware instead of they are not willing to share, and that is how a another story is born. IMO
It makes no sense, that LE on the spot explicitly says: "We are not sharing anything whatsoever about this missing persons investigation", and then call him back saying hey wait a minute, maybe it is interesting for you to know that we have no idea how long RT and BT were separated before she went missing or how far she was from the RV, we really want to share that with you.
Makes no sense, just wrong interpretation maybe even on purpose because LE did not give them anything. IMO
