When you listen to the video of this conversation, you can tell that KC is basically admitting that she has lied about other things but not the fact that she doesn't know where Caylee is BUT that could also mean that she knows that she was put in a river and could have relocated so, no, she wouldn't know where she is or if she put her in the dumpster, then no, she wouldn't know where she is or if someone else buried her for her, then no, she may not know where she is. I have wondered about how she spoke of Caylee's whereabouts to her brother . . . cryptically at that . . . a normal person would say something like this:
"Okay, I know one thing, Zanny would never hurt Caylee. I can't understand why Zanny would do this to me. We were such good friends for such a long time and she never showed any signs that would make me worry that she would take Caylee. I'm sure Caylee is fine, I just can't put my finger on where Zanny would take her . . . this just doesn't make any sense. I kept hoping and hoping that she would just call one day and say she was sorry and that she was bringing Caylee back, that she just wigged out for some reason. I wouldn't press charges against her because I know she loves Caylee and Caylee loves her."
Something like that, you know . . . not, she's safe, she's close, bottom left, lies, lies, lies.
