Just thinking about the parallels in this case, and the Gannon Stauch case.
In that one, the early narrative was that “Gannon ran away.” Most of us didn’t believe that, as the account was both strange, and law enforcement was not behaving as if they actually believed that.
They never corrected the narrative, while maintaining all along that it was a “missing persons investigation.”
CSI activity at the home, told us what that case likely was (foul play).
Here, we have an alleged bike ride, but law enforcement behavior that does not jibe with there actually being one. If there was a bike ride, then we’d be seeing corresponding behavior from law enforcement (standard abduction playbook).
Likewise, we have seen CSI at the home, and that search of a property that BM apparently worked on.
What is telling law enforcement that this isn’t an abduction is anyone’s guess, but I have no doubt that they don’t believe there was one.
