The one thing that really keeps me believing it's KC alone who is responsible for Caylee's death is that she is on trial for her life, and yet hasn't offered up a single pertinent bit of information or evidence to LE that points to another person of interest. We see her and her family toss Amy, Jesse, others, under the bus repeatedly, yet absolutely nothing links them to the crime. Amy was in Puerto Rico when Caylee disappeared IIRC, and it's so clearly not Jesse. Initially KC says she's protecting her family, yet no guards were put on them and they stayed in their home, the same home that everyone saw on the news hundreds of times. If she can offer up nothing plausible, then in my mind, the truth itself is so sordid and horrible she has decided to remain mum. If I were in her shoes and had any inkling of proof to offer to LE to divert suspicioun from myself, I would be screaming names from the rooftops, offering fact afer fact that ZFG existed. But everything she has thus far claimed has been 100% bogus. This is a woman on trial for her life. There is no way she would protect her daughter's murderer and be executed in place of that person. KC is a person with no regard for others. How can she expect anyone to believe that she is sitting in jail protecting someone who killed her only child? It requires a suspension of belief no thinking person can achieve.
Except this: Casey was arrested on July 16 and from that point forward had an attorney who has told her NOT to talk to police or anyone about her case. We have seen Casey, on the day she was arrested for murder tell the police that she has wanted to talk with them for so long but with her attorney present. The police called Baez who came down to the station. Baez took Casey into another room and a few minutes later told police they would not be talking to them that day. So clearly, Casey is being restrained from talking to police by her attorney. Why this is, we don't know. But that is not an indication of guilt or innocence.
