This just occurred to me today. I've been wondering, how if Zanny never existed, that Casey had been talking about her for years and even Caylee apparently knew her - talked about her dog.. I have long felt like Casey's real job was "escorting" or to put it more basely, hooking. What if Zenaida was the Madam who arranged her gigs and watched Caylee while Casey was entertaining? What if Z was looking at the sawgrass apts. for another "shop"? Maybe sometime in the spring, Z decides to hit the road for a better more opportunistic town. No doubt she never would have told Casey her real name. Still - no way she kidnapped Caylee, but this might explain something. At least it gives Casey someone to pin it on. just a way out theory.
