PHOENIX (AP) — Jurors in the trial of a woman charged in the stabbing and shooting death of her lover watched a videotaped interrogation of the suspect Wednesday during which she insists she didn't kill the man, but notes if she had, she would have killed him quickly and humanely.

Jodi Arias is charged with murder in the June 2008 death of her on-again-off-again boyfriend Travis Alexander. If convicted, she could get the death penalty, becoming just the fourth woman on Arizona's death row.

She first told police she knew nothing of the killing. Later she said two intruders burst into the home and killed him while she managed to escape. She now admits to the killing, but claims she had to defend herself against an enraged and abusive Alexander.

Jurors on Wednesday watched a videotaped interrogation of Arias, 32, after her arrest. A detective grilled Arias, explaining that all the evidence points to her. She insisted she did not kill him.

Mesa police detective Esteban Flores continued to press her on the tape.

"You shot him in the head, then you got a knife and you stabbed him," Flores said. "Jodi, tell me the truth, please."

"I don't think I could stab him. I think I would have to shoot him until he was dead if that were my intentions," Arias told the detective. "But I would have to wear gloves.

"If I had it in me to kill him, the least I could have done was make it as humane as possible," she added. Continued...
