Jodi Arias trial: Domestic violence expert testifies for defense

      PHOENIX (AP) - A domestic violence expert is testifying in the trial of a woman accused of murdering her former boyfriend in his suburban Phoenix home.

      The expert resumes testimony Tuesday after detailing her expertise to jurors on Monday.

      A psychologist who diagnosed Jodi Arias with post-traumatic stress disorder and amnesia concluded nearly six days of testimony on Monday. The prosecutor questioned his credibility and accused him of forming a relationship with Arias that biased his diagnosis.

      Psychologist Richard Samuels denied the accusations. He says he based his diagnosis on 35 years of experience and multiple tests.

      Arias faces a possible death sentence if convicted of first-degree murder in the 2008 killing of Travis Alexander.

      Authorities say she planned the attack on her lover. Arias first denied any involvement, then said it was self-defense.
