The trial went late due to defense expert witness Dr. Robert Geffner needing to return to California, so the court was scrambling to get all of his testimony in.
The day started with a fierce cross-examination. Prosecutor Juan Martinez accused Geffner of making errors on psychological tests he gave to Arias -- tests that purported to show she suffered from post-traumatic stress disorder.
The psychologist tried to battle back by claiming he didn't understand the questions or he couldn't answer with a yes or no, or he simply couldn't remember.
At times, the clearly frustrated prosecutor started yelling, sparking a string of objections by Arias' defense attorney Jennifer Willmott; then Martinez noted Geffner isn't licensed in Arizona.
Afterwards, Martinez sat down and under friendly questioning by Arias' lawyer, Geffner chatted easily about his credentials, his psychological training and experience and he confidently repeated his testimony that Arias walked in on Travis Alexander masturbating to child pornography. Geffner referenced testimony about porn on a Mormon bishop's computer that popped up during a retreat; Travis telling an unnamed witness he got into pornography after being molested as a 12-year-old boy by an older adolescent.
The trial continued with questions for Geffner from jurors.
The question hovering over the trial: Will Arias get back on the witness stand?
