I doubt if Nifong or Wilson had anything to do with making this one up. It's so pathetic and obvious that it's a lie and does not fit with any other objective evidence that only Mangum is stupid enough to make it up. Nifong and the investigators, including Wilson, have taken such a beating from the defense that I think they're afraid to tell anymore lies, especially the investigators. This new story, I believe, came directly from Mangum and is the beginning of her death rattle in this case. She has cornered herself in lie after lie, story after story, and this was an act of desperation, plain and simple. It is so absurd as to be comical because it completely denounces her entire previous timeline and all known objective facts. Mangum's latest story cannot be shoe-horned into the objective facts known in this case. Her new story, she thinks, will explain the identifications she made, which is the next task before her. When push comes to shove, I don't think she will be able to get on the stand and repeat this. Surely not even she can expect the world to suspend reality and common sense to the degree needed to believe her latest fairytale.
Unless she shows up for court drunk on her ass.
