I wonder, how many folks have the phone number of their friend's spouse or their friend's kids?
Maybe I'm outing myself as a weirdo but I don't have the cell phone number of anyone's husband or kids.
I'm thinking the friend did not contact BM, but once she heard SM was missing, she did contact LE and that was the catalyst for the investigation to go the way it did.
IF it was BM that disappeared SM, would he feel confident enough to stage the bike & head out to "Denver", knowing SM's best friend was in "panic mode", frantically trying to reach her because the conversation ended so strangely the night before?
I don't think he would, but that's just MOO.
