It has been said, prior to finding remains, that if they charged CA or GA prior to KC's trial that CA and GA could plead the Fifth. IMHO. I do not see that it matters one way or the other at this point. The state can enter GA and CA sworn statements into evidence. No need to have them testify. The state could call them to testify, call them to the witness stand, ask a question and then have CA refuse to answer on the grounds it might incriminate her. Yes, that would look good. So at this point, if LE and the State thinks they have enough to charge anyone with anything of any kind I think they will go for it. JMO.
