PHOENIX (AP) — The prosecutor in Jodi Arias' murder trial is working to portray the defendant as a manipulative liar who "liked to play the victim."
Prosecutor Juan Martinez is questioning a defense witness who says Arias suffered domestic abuse at the hands of her lover.
Psychotherapist Alyce LaViolette has been testifying for more than a week.
Martinez on Tuesday hammered LaViolette over how she could know Arias didn't lie to her. The witness says she believed Arias, but she has no way of knowing whether she was truthful.
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. Arias says it was self-defense.
LaViolette resumes testimony Wednesday.
