So if Steven did walk away, why didn't he take an extra pair of pants, a change of underware, something (anything!) besides a file folder? No one going through his belongings would have recognized a pair of pants missing or would have counted his underware to ensure it was all present. No matter where Steven intended to start his new life (If that's what one believes happened), he could have used these and other basic things that wouldn't have been missed by the people left behind to sort through his stuff. Steven didn't walk away with a duffel bag...even though he could have. This to me means he didn't walk away. Did his new life come with a new wardrobe? Was he all of the sudden going to have the funds to replace EVERYTHING he's ever owned, down to his socks? I just don't think so.
And if Steven left his car behind with the knowledge that it would be repossessed, why keep the keys? Why not lock them inside, since he would have no use for them. Steven kept the keys, in my opinion, because he had every intention of returning to his car. If he wanted it towed, repossessed, found, whatever, he should have parked in front of someones house, in their driveway, or on top of a fire hydrant, but he didn't....he parked it in the only area in SCA that it might possibly go unnoticed. And to me, that doesn't add up to someone who walked away.
But I'm just as stumped as ever.....
