Eighteen Arizona citizens have spent more than two months listening to witnesses, looking at evidence and asking Jodi Arias questions about the slaying of Travis Alexander. And it's not over yet.
But, only 12 of them will ultimately decide on Arias' fate.

After closing arguments, six of the jurors will find out they are alternate jurors. They will listen to jury instructions and then watch the 12 official jurors head to the jury room to begin deliberations.

The alternate jurors will not be released from service at this time. During deliberations, if any one of the 12 jurors are released for any reason, an alternate juror would be called back and deliberations would begin again.
The Arias jury has been closely watched by the gallery and Arias herself. During Arias' testimony, she often answered questions while looking directly at the jury.
