If she doesn't exist, then the theory is that they don't intend to have her testify at the trial. Couldn't the defense subpoena her, if the prosecution doesn't I assume, even in Florida, if a prosecutor has a witness that doesn't exist, they are basically history.
Yes, it is quite possible that witness 8 was a figment of Benjamin Crump’s imagination, with her part played by at least two actresses. The entire story that she tells seems made up to fit the “facts” that were publicly available (some of which were wrong) at the time she told it. However, they don’t necessarily line up with reality. Add to that the fact that the girl who testified to the prosecutors was clearly heavily coached, saying things like “oh, you want that?” She also said something very strange about her cell phone when asked if it was in her name. She said, “Now, it should be now in my name.” At the time of the shooting, the cell phone number in question was tied to a prepaid phone and had no name associated with it.
Can you begin to understand why the defense has so many questions about witness 8?
Incidentally, Mary Cucher is another witness whose recollection of that night’s events matches up with the false information that was in the media, rather than the reality of what happened that night. Several days after the shooting, when Trayvon’s picture was all over the news, she came out and said that she remembered that it was a little boy screaming that night. The problem for her is that Trayvon was no little boy, but anyone who was following the news at that point thought that he was because of the pictures that were on television and the front page of the newspapers. She clearly lied to both make herself more important to the case and to make sure that justice (as she saw it) was carried out.
