For most of us, that's just one small piece of why BM leaps to mind as a top suspect.
I'm sure you know all the other pieces, but I don't think I know a single WSer who goes by just one fact alone.
We all use fairly complex thinking about these things, and many variables. For me, the 10+ searches and that one road closure up past Puma Path are quite intriguing. Note that these searches were under the auspices of CCSO. In the Gannon Stauch case, we later learned that the FBI was active outside the state (not necessarily searching, but certainly looking into evidence). We also learned that LE, in the Stauch case, was in touch with LE in at least two other states not counting Florida. They didn't announce all this publicly.
We know evidence was taken out of the Morphew home. We don't know what it is.
In the absence of any other locale/person being the focus of the investigation, I'm going to say that BM is definitely under scrutiny - here, and in Salida.
No one should be "convinced" of guilt or innocence of any party at this time. But we can have our opinions and that guides us in what we try to discover (even if it's not admissible in the Court of Websleuths - none of us wants to have rumors governing the discussion).
Several have posted their entire list of suppositions (none of it rumor) as to why BM has their attention as a suspect in this case. No one has used just one fact. However, in this forum format, it's easier to discuss one or two things at a time.
