From the photos I saw that show her with



, wven though the face was blurred out you can tell she is white and brown haired, and I am guessing that they thought it would be easier for him to make it down to Mexico and then when all the Brouhaha blew over and everyone forgot about the case, Xtina could join him. They never thought it would become such a big deal, with the whole nation focused on this case.
Mygirl, I totally agree about Xtina sticking out like a sore thumb, especially since many Mexicans are very dark -skinned. If they had decided to relocate to a different latinamerican country where most people are of Spanish or European descent, then it would be easier to blend in. I also imagine they would plan to hide out in a little village somewhere that doesnt have cable tv access so that they wouldnt be recognized.
It is still my opinion that he planned for Xtina to join him at a later date with their daughter, thinking that the note he left would prove that Xtina was innocent, but things went differently, thank goodness.
Just my opinions, so dont flame me !
