I'm still not entirely clear about what the status was of the investigation of the shooting of CV when Lori departed Arizona for Rexburg. The press in Arizona seemed to indicate a quick conclusion that it was a shooting in self-defense, and many posters here have made comments that police bungled on scene (cleaning up blood, failing to reconstruct the shooting and where various parties must have been standing, etc), but some of the comments of Arizona investigators indicate preliminary statements from Lori, Alex, and Tylee were not believed and the investigation was ongoing.
So, WERE investigators there reconstructing events in an effort to build evidence to refute those statements, and it was just taking a lot of time, and then they lost track of Lori's whereabouts until Kaye Woodcock managed to come up with Lori's new address in Rexburg?
IIRC, toward the end of August, the owner of the rental home in Chandler had asked Lori to vacate by the end of August. Was that what motivated the early September move? Or, had Lori somehow gained knowledge about the course the investigation of CV's shooting was taking? (I'm dismissing anything Lori told MG because it came out of Lori's mouth and I don't grant any credence to anything from there.)
ETA: After I posted this, I see others posting Justin Lum's tweet that Chandler PD is close to submitting charges to Maricopa County. So, there you go. Hallelujah!
