CarlK was nice enough to PM me the pictures of both Cactus HS LK and Horizon HS LK. So both of those women are not a match to Longview LK which reinforces my belief that it was shortly after high school she stole the ID.
But both the highschool LKs have somewhat similar coloring (the one at Horizon was very close in features to Longview LK). I wonder if she stole LK's identity because she COULD (ie she looked similar enough that she actually stole a driver's license from said person rather than forging all new documents).
As far as the Irish thing that Ambercat suggested: the interesting/difficult thing about LKR is that she could be anyone. I mean, she looks like many of the "portenos" that I saw down in Argentina. She looks like some of my Italian friends. It has also been suggested here that she might be part Native American. We might as well throw in Mexican, too.
ullhair: Because her looks (excepting her height) are in some ways universal it is giving us a lot of people to look at.
Which leads me to my next point. We have been putting a lot of good suggestions out here as to who LKR could be. Maybe it would be a good idea to compile a list of some sort? Possible people? People that we generally agree wouldn't be a match (circumstances, dates not right)? Since I am kinda new at this maybe one of you can tell me how you all try to narrow down suspects in cases like these to move this case forward somehow.
