The following is MOO.
I think it's a bit misleading to compare Beverly England's case to Suzanne's. Other than both being women who went missing in CO, there aren't a whole lot of similarities. Also, the original pathologist categorizing BE's remains to be a pioneer woman, pretty sure something like that would just not happen these days. Forensic technology has become much more precise.
I have always been on board the K.I.S.S. boat. BM is an outdoors man. I don't see him as being a big detail type guy. He had the vast, unforgiving terrain of CO to work with, along with his knowledge as a landscaper. I do not see him as being a very creative type, taking into consideration the absolutely generic landscaping he did for the Puma Path house. I just don't see BM doing anything real complicated, thinking far outside the box. He's also not a professional criminal, he's a guy who likely murdered his wife. So, the simple solution to the problem of what to do with Suzanne is probably the most likely. He had a lot of tools at his disposal to make it happen, including all that wilderness.
At this point, I think if Suzanne's remains are found, it will be an accident. Someone out hiking, or hunting, or stops to pee on an ATV. But I don't think she is going to be found. I posted about this a while back, but I think it bears reiterating: Some of Ted Bundy's CO victims have still not been found to this day, even with Bundy highlighting areas where he disposed of them and extensive searches. And Bundy was not an outdoorsy type of guy, nor had he spent a lot of time in CO.
I agree that BM likely thought that through his position as a FF would make him above suspicion. I think he was shocked and angry when it didn't play out that way, and it makes me very curious as to how his three thirty hours of interviews went. I think there was something that indicated immediately this was not someone who had an accident on a bike ride. His position with the FFs may have even worked against him; what if one of his buds heard him talk about SM in a disparaging way or make light of DV or something along those lines?
I also wonder about the quasi- militia group in the area; while I don't think it had any bearing on Suzanne's disappearance, I do wonder if loyalties come into play somewhere. I am not implying BM was involved in any of that, but it's something that makes me think and consider that this is a very small area, population-wise. Lots going on in the background, perhaps?
I'm very hopeful the incoming DA determines there is enough evidence to prosecute the case. I have these dark thoughts that while many of us are eagerly awaiting an arrest announcement soon after she takes office, we hear nothing other than a statement that says she's working with LE on the case.
