I am only looking at the two houses whereby the remains were found behind. I think Gonzalez is a pretty common name in Florida, but Zanaida not so much. The fact that those two houses have one listing a Gonzalez and the other listing a Zanaida in reverse lookup is the most unique coincidence. It either means they live there or once lived there. Casey would likely know. I think she put that name together on the fly. I don't think she researched it. The first name of the Gonzalez is perhaps an additional clue she tossed in as a variation of the middle name she gave later on. I think she was giving "real" clues all along, as people like Padilla said there is a bit of truth in every lie. If you go back to the clues being given to Lee and the family, about closeness, a T, familiar places, hangouts, etc. you will find that perhaps she was telling them all along.
