In a jail-house conversation with her mother (Cindy Anthony), Casey said the following about Caylee:
Cindy: And your gut tells you she's close....
Casey: She's not far. I know in my heart she's not far. I can feel it.

As noted in the opening post, the remains of a child's body were found near George and Cindy Anthony's house. If those are Caylee's remains, then Casey was telling the truth: Caylee was not far away.
