I think she admits that - that is a lie but then she begins to spin elaborate tales (just like KC) about what could be the real story- the REASON KC had to tell those lies. She just CANNOT admit what the evidence is telling everyone.
Probably to see what type of stories were told as to abduction scenarios. She probably thought she could just become famous- as the young mother who desperately needs America's help to find her beautiful daughter!
This makes me lean more towards premeditation which I've been trying desperately to avoid!
