Jodi Arias, who is on trial for the Arizona murder of Mormon Travis Alexander, testified about the details of the chilling moments when she killed her ex-lover on Wednesday, Feb. 20 .

Arias continued her testimony from Tuesday when she said she and her victim decided to take pictures of him in his shower for a "photo shoot effect." There, she accidentally dropped his camera and 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.

"I was scared. I was thinking crap because this is everything I was trying to avoid downstairs when he started to get mad... I still screwed it up. And now he's pissed again," she said.

Arias said after she pointed at him again, he began to lunge at her as he threatened to kill her. Suddenly he just fell and she didn't realize that she had shot him until after he fell on the ground.

"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," she said. "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. 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."

Arias and her attorney then moved on to when her victim was stabbed. She said she doesn't remember stabbing Alexander or when she dragged his body across the floor. When Numi asked about the knife, she said she remembered dropping it because it made a loud noise when it hit the tile floor.

"There are a lot of gaps. I have no memory of stabbing him," Arias told her attorney. "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," said Arias.

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

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

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

"I just remember more the feeling during that time. Not pictures and things that I can bring back," said Arias. "I just remember screaming. And I don't remember anything after that - not immediately."

When police found Alexander's body, they discovered that he had been shot in the face, stabbed 27 times and his throat was slit from ear to ear. Arias lied at first and said he was killed during a home invasion, then later admitted that she killed Alexander as an act of self-defense because he attacked her.

Arias' first-degree murder trial is expected to resume on Thursday, Feb. 21. If Arias is convicted of the murder which 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.
