Perhaps at this point the Anthony's do know the truth-maybe even the whole truth. And they are unwilling to set Casey up for a death penalty case. They have lost one loved one-I suspect they will not be willing to lose another one for whatever reason.
But I wouldn't be inside those walls for all the money in the world.
I happen to agree with you entirely. I believe that the family knows that Caylee is dead. This business about kidnappers and Mexico is a total act on the family's part. They themselves don't really believe what they say.
