Thanks for the clarification Gardner 1850. And thanks for all you do! The timelines are extremely helpful.
I had been trying to figure out how AC got from Rexburg to AZ on his final trip (apparently with a stop in LV to get married). I thought that if I could exclude the Jeep, I could possibly narrow down the remaining vehicles to: Lori's car, AC's soon-to-be wife's car, Melani's car, the white F-150 truck (registered to CV?), and CD's Avalanche. It was obviously a long shot, as we don't even know if the first three were ever in ID.
I was thinking that if AC and his soon-to-be wife did leave in one of the last two vehicles (one which was likely a packed truck?), they could have left at the same time as (or even as part of a two car caravan with) Chad & Lori. But there's no evidence to support this, and I probably should have counted to 10 before I posted.
I was just trying envision a scenario that would perhaps put Chad & Lori in AZ around the time of AC's death, as I find the circumstances of his death suspicious and think it's plausible that Chand & Lori may have had motive kill him. But there could be other explanations for AC's death. Someone recently posted that AC may have even committed suicide, which is something I hadn't even thought of.
