Another thing about that older picture of Vicky: to be honest, and this is just my personal opinion, she really doesn't look like someone who would give up her known life as it was for a life on the lam, which could only have one sad ending. Which makes this whole scenario even more bizarre.
It's such a striking difference, that it almost makes me switch my feeling about this to an alternate scenario: one in which Casey somehow got hold of Vicky's service weapon, ordered her at risk of bodily harm to undo shackles and chains, hand over money and somehow did some harm to Vicky...then fled. Or, ordered her to do the driving, realizing he would need her early on. But now, I do have some doubts about whether Vicky intended this to be an "escape" and somehow was a victim of a kidnapping.
I still favor the escape theory but I'm beginning to have some doubts.
I do agree very strongly with you...those running this investigation need to start circulating that older picture of Vicky White.
