Jodi Arias Takes the Stand

"I recall there was some pornography on the computer," Lonnie Dworkin, the computer forensic analyst testifying for the defense, told the court. "I don't recall specifically if there were women's breasts or other content."

Dworkin combed the hard drives and memory cards of computers and cameras owned by Arias and Alexander. He found images including the T-shirt and underwear, pictures of Arias hugging friends and a dog, and pictures of a penis that Alexander sent Arias on the internet, according to his testimony.

The defense has spent the past week presenting evidence that Alexander kept up appearances of being a devout Mormon and a virgin in his social life, but had an erotic sex life with Arias that included sending her a lewd picture of himself, phone sex, anal sex, oral sex, and taking nude photos of one another in sexual positions.

Arias could face the death penalty if convicted of murder, which prosecutors say was premeditated and extremely cruel in that she stabbed him 27 times, slashed his throat, and shot him twice in the head. They have also argued that she lied to investigators and friends about killing Alexander until she was cornered with a mountain of evidence proving that she did. She then said she killed him in self-defense, they argue.
