That's interesting, let's talk about that. First, if someone exited that truck on the passenger side, it may, or may not have been Gannon. Could it have been an accomplice? A murderer yet named? A relative? Who knows, right?
But assume it was Gannon. Then what is the next theory from there? I imagine it would be that Gannon did in fact leave the home at the stated time on Monday, never to be seen again? Problem here is this, there is no video depicting such.
So, he went out a side gate, and sneaked out unseen? Or scaled the backyard fence, and escaped into the outback?
If these scenario's have plausibility, then why is the LE search going on where it is? Did Gannon run that far? Did some unknown person kidnap him and the investigative trail led to where the searchers are?
What say you?
