It's been a while since I've posted on WS, (Hello from the Heather Elvis threads) but this case has brought me right back in.
Where is Gabby's phone and laptop? Does the FBI have access to her iCloud account? Other accounts? I'm positive LE can clone the IMEI to another iPhone to gain all sorts of information that is available from the applications that were installed.
As far as being able to make the drive in one trip, some of you might be amazed at the capabilities of the human body. About a decade ago, I drove a fully loaded Expedition towing a fully loaded Uhaul trailer from Kansas City, MO to Corpus Christi, TX, unloaded the SUV, unloaded the trailer, set a few things up in the new apartment, drove back to Kansas City, MO, loaded the SUV and the Uhaul again, and made it to Dallas before I was too tired to go further. It was 13 hours to get there, 2 hours of unloading, 12 hours to get back, 4 hours to re-load my belongings, and then 7 hours to Dallas. That's 38 hours straight. I was not in as good of physical shape as BL, didn't have his youth, and did not have the adrenaline boost of, ya know, allegedly murdering someone, and even then, it was possible.
I think the guy on the Trail Cam looks very similar to BL, but HOLY CRAPOLA imagine capturing that on your Trail Cam? Everyone buy Trail Cams. That image is shocking no matter what.
