I just had one of those things where the light bulb goes off and I had to type it out before it left again.
FDF had her in 4 different high schools, and moved constantly before inexplicably seetling down and letting her attend Forest Park High for almost 2 years. He was also almost constantly on the move before that too, but there were short periods where he would stay put for what seemed to be no reason right? I don't believe that he was running from LE, he would have thought himself too smart to get caught anyway. We should all remember that comment about him taking Sharon from Chicago from down by the warehouse where they made the snuff films and taking her so that "he" wouldn't strangle her. On the off chance that is true, wouldn't the mysterious "he" have been awfully pissed off?
What I'm getting at is maybe he was running from the person he stole her from and the periods of staying put were when he knew that other person could not follow them. Like when that person was in jail.
THis is goinf to take a lot of cross referencing of names and prison records, so if someone wants to help that would be great. Otherwise I'll do it tonight.
