"Did you go to Mr. Alexander's home on June 4 with the intent on killing him?" Nurmi asked Arias on Monday.
"No, I didn't," she said. "That was never a thought."
Arias' grandparents had reported a .25 caliber handgun stolen from their Northern California home about a week before the killing — the same caliber used to shoot Alexander — but Arias says she never knew her grandfather had the weapon. Authorities believe she brought it with her, though she has testified she shot Alexander with his own gun as he chased her into his closet after body-slamming her and threatening to kill her.
"He was trying to kill me so I was defending myself," she said.
Alexander had also been stabbed and slashed 27 times and had his throat slit. His body was found by friends about five days later.
Arias has testified that in the months leading up to his death, Alexander had grown physically abusive and beat her on numerous occasions. However, no witnesses have testified and jurors have heard nothing to indicate that Alexander had ever shown violent behavior, and there has been no proof given that he owned a gun.
Arias told authorities repeatedly after her arrest that he didn't own a gun. That story changed after several years in jail when she admitted to the killing.
Arias has been on the witness stand for nearly two weeks. Once she concludes her testimony, jurors can pose questions to Arias via written notes provided to the judge, something allowed in Arizona criminal cases.
