I think it is very possible that he can be with a couple outside of Texas, Arizona or Florida, and no one would have any idea that he is a missing child. Most people don't read internet blogs on missing persons, etc. And when is the last time this case saw intense national media coverage? Many working people, for example, don't watch Today because it's on in the morning. So I think it's possible that someone could have Gabriel and figure that every day means that his appearance changes a little more, and after a year, he might not be recognizable. He would also be a fixture in his neighborhood.
