PHOENIX (AP) - A defense expert who diagnosed Jodi Arias with post-traumatic stress disorder and amnesia returns to the witness stand for a sixth day of testimony.
Arias faces a possible death sentence if convicted of first-degree murder in the 2008 killing of Travis Alexander in his suburban Phoenix home. Authorities say she planned the attack on her lover. Arias initially told authorities she had nothing to do with it then blamed it on masked intruders. She later said it was self-defense.
Psychologist Richard Samuels answered more than 100 jurors questions last week, most focused on Arias' lies and how Samuels could be sure she is telling the truth now.
Arizona is 1 of a few states where jurors can query witnesses through written questions read by the judge.
