Jodi Arias faces the death penalty if convicted of first-degree murder in the killing of Travis Alexander in June 2008. She resumes testimony Tuesday.
Arias sobbed as she described for jurors how Alexander abused her both mentally and physically, once kicking her in the ribs and breaking her finger. His friends say she is lying.
She has testified in Phoenix about their volatile relationship and claims she killed Alexander in self-defense. Prosecutors say Arias killed him in a rage, stabbing and slashing him 27 times, slitting his throat and shooting him in the head.
Arias initially denied involvement in the killing before settling on self-defense.
Jodi Arias' crooked finger, she says, is evidence her ex-boyfriend Alexander abused her.
"He went to kick me again, and put my hand out, and to block his foot, and it clipped my hand and hit my finger," Arias testified.
Although, the serial liar now on trial for his murder admits she never went to a doctor and never called police.
"I definitely didn't want him to get in trouble," she testified.
Convincing this jury she was abused -- even though there's no corroborating Evidence -- is key to the 32-year-old's claim she was forced to kill Alexander in self-defense.
"When you just look back, you don't think that it would end up the way it did," she testified.
On her fourth day on the stand, Arias' father and younger brother were in court for the first time. They watched her tearfully detail several instances of alleged sexual and physical abuse.
"He pushed me down on the ground in his bedroom," she testified. "He wanted me to stay so I guess he could finish yelling at me."
Arias testified after one fight she considered suicide.
"I didn't have a lot of self-esteem at that time and, I just , I was kind of a doormat," she testified.
But the prosecutor points out Arias kept going back to Alexander - it was several months later she repeatedly stabbed and shot him. And she never accused him of anything until she was facing the death penalty.
Alexander's siblings were visibly angry as Jodi Arias' testimony seemed to turn her trial into one of the victim. They believe she wasn't satisfied killing their brother, and is now murdering his good name. They're looking forward to the prosecutor challenging Arias' latest story on cross examination.
