I always thought that KC came clean to her mother during the second home stay in mid September. This interview is from Sept. 2nd so if this was another slip then they knew much earlier.
This is also from the transcript;
MARK WILLIAMS, WNDB NEWSTALK 1150: Well, the big story today, of course, Nancy, was the deal for limited immunity that expired at 9:00 o`clock this morning, basically, the opening of business at the county attorney`s office, and she did not take it, nor did her attorney, Jose Baez, take advantage of that.
And of course, as you know, Nancy, that the deal would have been if she would have talked about where she may have placed Casey`s (SIC) body or given the whereabouts of Caylee`s body, she would not have been prosecuted but they could have used any evidence gathered to use that against her in the investigation, and of course, any subsequent trial. That is the big thing that happened today. No movement there whatsoever. So she still remains in the Orange County jail.
I'm thinking at this point they saw no reason to take the limited immunity because they may have believed that they would be able to find the body and move it after the water subsided.
Just out of curiosity how much would have taking the deal helped her? Are we talking a sentence less than life or the DP?
They could use whatever they found in the investigation so maybe it didn't make sense for her to cooperate due to their being so much home stuff with her. :waitasec:
