LATEST!  JODI ARIAS describes for stunned jurors a blow-by-blow account of how she killed her lover Travis Alexander.

“He said, ‘I will f***ing kill you, b*tch,” Arias testified, telling the jury that the fatal encounter was triggered when she dropped the victim’s camera on the tile floor of his bathroom after a sexually themed photo shoot.

Arias told jurors she ran out of the bathroom into a large closet and grabbed a gun she knew Alexander kept on a high shelf. She recounted in explicit detail shooting her on-again off-again boyfriend but claimed that she did not immediately remember stabbing him.

Alexander was shot in the face, stabbed 27 times and had his throat slit.

 “When I grabbed the gun I ran out of the closet,” she said about their final encounter, wiping her eyes. He threatened to kill her while cursing at her and she said at one point she broke away from him.

“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,” she told jurors.

“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 then testified Alexander previously had nearly killed her and she feared for her life before killing him. But while she described shooting him with detailed clarity, she claimed she could not immediately remember stabbing him, RadarOnline noted.

“There are a lot of gaps. I have no memory of stabbing him,” Arias said as her attorney gently led her through the testimony.

“Do you remember dragging him across the floor,” she was asked and was barely audible when she answered, “No, I just remember trying to get away from him.

“I have a few memories…I have a vague memory of putting the knife in the dishwasher but I’ve put the knife in the dishwasher before,” she said describing the knife that she used to stab Alexander.

But she claimed to have no immediate recollection of stabbing Alexander. “I was in the bathroom. I remember dropping the knife,” she testified. “It clanged to the tile and made a big noise.

“I just remember screaming. And I don’t remember anything after that — not immediately.”

Arias described driving away from Alexander’s house and why she didn’t call 911.

“I was scared,” she said. “I couldn’t imagine calling 911 and telling them what I had just done. I was scared of what would happen to me. “
