Jodi Arias, who is currently on trial for the 2008 Arizona murder of Mormon Travis Alexander, will be cross-examined by prosecutors for the first time on Thursday.

On Wednesday the trial climaxed when Arias testified about the chilling moments when she killed her ex-lover. The California woman also shocked the jury when she gave specific details about their sex life and how she shot Alexander.  She then said she did not remember stabbing Alexander 27 times.

Alexander, 30, a Mormon motivational speaker was shot in the face, stabbed 27 times and his throat was slit from ear to ear. When Arias' defense attorney Kirk Numi asked her to describe how her victim was stabbed, she replied: "I have no memory of stabbing him. There are a lot of gaps."

Arias gave details about the horrific crime for the first time on Wednesday, after she lied in 2008 and said he was killed during a home invasion. She later admitted she killed Alexander as an act of self-defense because he attacked her.

Arias testified on Wednesday that after she accidentally dropped his camera as she was taking sexually explicit photographs of him, Alexander became so enraged about it that he threw her on the floor.

"He lifted me up as he was screaming that I was stupid idiot and he body slammed me again on the tile," Arias testified, according to HLNTV.

Fearing for her life, she ran and hid in the closet and Alexander chased her. Arias said she grabbed a gun in his closet and pointed it at him to get him to stop chasing her. Arias said he lunged at her as he threatened to kill her. Suddenly he fell and that's when she realized she had shot him.

"He said, 'I will f***ing kill you, b*tch,' " Arias testified, according to Radar Online. "He was chasing me, I turned around and pointed it (the gun) at him with both of my hands."

"He kept running, like a linebacker. I didn't mean to shoot him or anything. I didn't even think I was holding the trigger. I didn't even know I shot him. It just went off," she added. "He lunged at me and we fell really hard. I didn't even know he had been shot. We were struggling and wrestling and he was getting on top of me and I didn't want him to get on top of me."

When Numi asked about the knife, Arias said she remembered dropping it because it made a loud noise when it hit the tile floor.

"I remember I was in the bathroom, I remember dropping the knife and it clinged to the tile and it made a big noise. And I just remember screaming. I don't remember anything after that," she said.

She said she "freaked out" when she dropped the knife.

"Do you remember dragging him across the floor?" Numi asked.

"No, I just remember trying to get away from him," she replied.

Arias' first-degree murder trial will resume on Thursday. If Arias is convicted of the murder that she has confessed to, she will likely face the death penalty and become the fourth woman in Arizona's history to die by lethal injection.
