I am thinking at this point LE is missing two things a crime scene and a body. They might have copious technological data tying BM to routes/ places he traveled to before and after SM’s disappearance and a motive but it’s not enough for a DA to bring forward charges.
What the passing of time will bring is people putting their guards down and letting something slip. By people I mean BM or any accomplices that may be directly or indirectly involved in SM’s disappearance.
Time also unveils new evidence in many cold cases.
If I were LE I would take the case files and pass them over to someone that can rebuild the case from the ground up taking a look at it through fresh eyes and perspective. Many cold cases get solved this way.
PS I don’t know why but I feel a woman is strongly tied to SM’s disappearance. MOO
Given the two separate warrant-based searches of the Morphew home and the fact that BM and SM were alone there with each other after the daughters left to go camping, I'm inclined to agree with Chris McDonough in that "I haven't left the home" as far as the original crime scene goes.
I think many look to the early morning Sunday (Mother's Day, 5/10/2020) trip out of town as BM's alibi and I think it was only his alibi in the sense that it provided an explanation for why he wasn't the person to discover that Suzanne was missing. The plan was likely for SM's absence to be discovered by his daughters who were expected to return on Mother's Day. Since they were delayed in returning and were alarmed when they could not reach her, SM's absence was instead discovered by the neighbor called to check on her.
But just because SM's absence wasn't to be discovered until May 10 doesn't mean her disappearance happened on that date or the day preceding.
IIRC, the daughters left town on Wed, May 6. On Thurs, May 7, BM called the Indiana contractor to whom he was subcontracted on the Broomfield job to inform them he'd have a crew working on that wall-repair job the coming week. Isn't it odd that BM notified that contractor on May 7 about the plan to begin that repair job the following week, but then failed to mention it to MG until the last minute? (Am I remembering correctly that she didn't know about it until he called her at around 4 am Sunday and asked her to get a crew - to include JP - pulled together and drive to Broomfield that same day?). What would be the purpose of neglecting to mention it to MG? Did BM want to ensure he had JP engaged to work out of town on that job before he told MG about it? Why?
There is a lack of clarity about exactly when SM was last
physically seen by anyone OTHER than her daughters or BM. Some have said SM visited a bike shop in Salida on Thurs, May 7 and others that SM was spotted at a sandwich shop on Friday, May 8, but to my knowledge those persons with whom she would have interacted at either of those encounters have not been quoted in MSM; instead those interactions have been described second- or thirdhand. I agree with others here who've expressed that LE must have some evidence about at least the May 7 interaction because they asked residents to retain any video surveillance beginning with that recorded Friday, May 8 (and through May 12).
So, if he were involved, BM might had Thursday night, the entirety of Friday, and all afternoon Saturday into early morning Sunday (and perhaps more on Sunday) to make SM disappear, dispose of her remains, and clean up any evidence anywhere it might be that might possibly implicate him. I wonder if he was careful to be at home manning SM's phone and social media during hours when others might interact with her and chose the rest of the time for any disposal and evidence clean-up occurring off-site.
Since social media interactions can be faked when they are not conducted on live face-to-face applications, I consider those "written post only" interactions less reliable indicators that SM was alive and was the person involved when they occurred. It's probably true that they couldn't be faked for long with close friends, but I think they could be faked intermittently and for at least awhile, say until the close friend urges SM to call or FaceTime or otherwise appear in person. Maybe it was just such a request that made BM act so strangely with MG on Saturday morning because that request raised the risk that someone might raise an alarm about SM earlier than he wanted that to happen and thus endanger his plan that his daughters would be the ones to discover her missing, and in his absence.
