Zannie the Nanny theory

We were watching the Dr. Phil interview with the parents. GA had mentioned something about Zanex. It clicked "She's with Zannie the Nanny" & "Zanny took her". So possibly Casey used Zanex to sedate Caylee when she needed a "babysitter" so she could go out & party or whatever. "Zanny the Nanny". So at some point too much Zanex could of been used and Caylee became unresponsive or passed. "Zanny took her". What do you think?

Hmmm that's an interesting theory. It certainly sounds like Casey.
