There was also the point about the black garbage bag and baby blanket Casey told Robyn about - and that is information the chaplain who told Casey about finding Caylee's body, did not know and DID NOT tell her.
JB was at the site on the day Caylee's remains were found. We all know how easy it is to over hear someone say we also found black plastic bags, and a blanket. Not saying that happened, but it is possible. JB did see KC that day, and he might have said something to her about the findings. JMO
