The defense proffered their expert witness

in the trial who read the messages while the jury was out.

Since the defense didn't get the evidence from the prosecution until days before the trial start, there was no time for them to authenticate they were Trayvons texts so the judge ruled the 100MB of cellphone pics, texts, and calls evidence as inadmissible.
