On Oct 30 and Nov 3, 2014, the media was mysteriously kicked out of the Jodi Arias courtroom so that a secret witness could testify. It was later discovered that the secret witness turned out to be Jodi Arias herself. Attorneys for the media fought hard to get the transcripts from those dates released and they finally succeeded.
Of the 249 pages, only 10 pages have Jodi expressing “remorse.” The rest of the transcripts talk about her childhood, past relationships, and the beginnings of her relationship with Travis Alexander. Perhaps unfortunately for the prosecution, the testimony ended at the exact moment where Jodi describes Travis sending her two pictures of his penis & those pictures being shown to the jury. If the defense does not put her back on the stand and the prosecution does not get a chance to cross-examine her, then this could be the last thing the jury hears coming directly from Jodi about Travis and add to that the images of those pictures in their minds. The entire testimony would have given her an opportunity to express “remorse” and to humanize herself, getting the jury to know her & her story without ever being questioned by the prosecutor. She even has another opportunity to do this in her final allocution statement (if she chooses to do it) again without being questioned by the prosecutor. Prosecutor Martinez has asked that the testimony be stricken from the record if the defense does not put her back on the stand. However, even if the records are stricken it’s debatable whether a jury can consciously “forget” two days of testimony, especially when the person testifying is the person who this case revolves around and whose life is in their hands.
An interesting note in Jodi's secret testimony is that she never addresses whether she still claims it was self-defense or not (which was her main defense throughout the original trial). Showing true remorse involves coming clean and telling exactly what she did. Her refusing to do so shows that she probably doesn't want to commit to a story that would hurt a future appeal or possibly a re-trial. Interestingly enough, on the same day the mistrial was declared, the Jodi Arias Updates Twitter account tweeted, "She admitted to defending her life, not a brutal murder." So it looks like we're back to self-defense now...
