We also know that on Oct. 16th, T. Black let it slip that Caylee was dead.
Black said during the live phone interview that the case is not just about the loss of the girl's life but about her mother's fate.
"It's very difficult," Black said in the TV interview. "This is a serious case involving not just the
loss of the life of this little girl, but the loss of whatever is going to happen with Casey Anthony."
