This week has been marked by a defense motion for a mistrial and the dismissal of a juror.

Defense lawyers say the juror made comments about the case to a fellow panelist that raised questions about her impartiality. The move leaves five alternate jurors, in addition to the 12 who will decide the case. The judge denied the mistrial motion.

Testimony has been ongoing for three months.

Arias faces a potential death sentence if convicted of first-degree murder in the 2008 killing of her lover in his suburban Phoenix home. She says it was self-defense, but prosecutors say she planned the attack on Travis Alexander in a jealous rage.
