I'm going to speculate here (inspired by
@MassGuy's post). It's mostly about what I imagine LE is doing and finding.
BM's alibi completely fell apart and did so in phases, which ended up including digital footprint from his truck as well as from his phone. BM's phone shows lots of phone calls to all kinds of people, but some of them have pricked up LE's ears and both those people and their neighbors have received a visit from LE, just to chat. BM's phone records over the past year also show some changes in behavior toward Suzanne. Suzanne's private SM also shows some messages and concerns. Some of these may be quite specific.
BM's friends in Salida are no longer standing by so staunchly. Some have said concerning things to LE.
BM never had a successful landscaping business in Colorado and isn't rich. LE now knows this.
BM visited several places near Monarch Pass in the days leading up to May 10. He did go to Denver, but to no place in particular and not to a job site.
No one has seen or talked to Suzanne - first they believed from May 8 onward, now it's May 9. So they're closing in on a date of homicide.
BM's social media is still being mined. Some of his friends and acquaintances have voluntarily given LE access to some of it. Google analytics shows interesting patterns in BM's movements, including some times when he left his phone at home.
Nephew and spouse have talked to LE more than once, and are now grieving and off SM altogether (at least insofar as this case is concerned).
I do also wonder if LE hit the jackpot in the form of Suzanne's private online conversations. Suzanne may have been part of support groups or even had an online counselor. Suzanne's medical records may show some pertinent facts.
None of this is quite enough for an arrest warrant.
But there's someone whose testimony could make an arrest possible and that someone may already be talking, or may talk soon.
--------
Anyway, that's my "BM" speculation. It's really hard to get very far with "stranger abduction" speculation, given the known facts. Suzanne-as-suicide is easier to imagine than stranger abduction, but for some reason, LE is convinced that didn't happen. I know when we finally learn what LE has right now, we'll all be surprised - as it's usually something rather small and unexpected that is the first clue as to foul play.
Surely we all agree this is a case involving foul play.
Well, SM posted it, so obviously, she did not see anything wrong there. You can interpret his posture in many different ways.
But the expression of his eyes is peculiar.
Or perhaps she was glad of the picture - you should see some of the pictures I actually put into photo albums when I was in my first marriage - they do tell a story. Could I see the whole story at the time? No, but I think deep inside I was thinking maybe someone else would see it and rescue me (which is, kind of, what happened).
SM stopped posting to social media broadly not too long after that photo, which interests me. I know that if I had posted something like it, my ex would have been furious - but also would have demanded I leave it up, because taking it down would make it even more suspicious (that's how he thought, we lived in a world of secrets and contradictory edicts).
If you look on SM's LinkedIn profile, it's interesting what she was reading/thinking of reading.
