Jodi Arias and her ex-boyfriend, Travis Alexander,, had increasingly violent sex in which he tied her to his bed, twisted her arm, bent her over a desk for anal sex, and made sex videos with her in the hours leading up to the stabbing and shooting frenzy that left Alexander dead.
It was a day in which Arias, 32, inched closer to telling the court how the killing of Alexander took place, but after several hours of increasingly emotional testimony the court was adjourned until Wednesday.
In her sixth day on the stand, Arias tearfully described the sex-filled hours that led to Alexander's death on June 4, 2008. She is charged with murder for killing her former boyfriend, but claims she was forced to kill him self-defense. She could face the death penalty if convicted.
"He tied me up, (on) the bed. It's not my favorite but it's not unbearable," Arias told the court.
She said he used a kitchen knife in the bathroom to cut the rope to the proper length, but she didn't remember whether he left the knife in the bathroom or brought it back to the nightstand in the bedroom.
"There are a lot gaps that day... a lot of things I don't remember that day," she said.
Arias and Alexander then took graphic sexual photos of one another and made a sex video, both of which Arias said were Alexander's ideas. Arias has girlish braids in the pictures.
But the mood of the afternoon turned, she said, when Alexander became angry over a scratched computer disk of photos she gave him. He threw the CD and Arias said she became "apprehensive" of his rising temper.
"I know he's getting angry because Napoleon [Alexander's dog] got up and left the room and he always leaves the room when he gets mad." she testified.
"I don't know that I was consciously thinking (of violence) but I was more tense. I stood up, went to walk over to him, to rub his back and make sure he was okay," she said. "But he grabbed me on the upper arms, spun me around and grabbed my right arm and twisted it behind my back, and bent me over the desk, and pressed up against me."
"I was scared he was going to throw me or something, kick me," she continued. "He pressed his groin up against my butt, did a few thrusts and then started pulling my pants down."
She said the pair then had anal sex, which Arias said pacified Alexander.
"I was very relieved. I felt like we had avoided catastrophe. It could have led to another fight," she said.
Instead of a fight, Alexander, who was 27 and a devout Mormon, and Arias decide to go upstairs and take more nude photos of one another. Arias said she hoped the photos would satisfy Alexander over his frustration with the scratched CD.
Evidence introduced earlier in the trial show that Alexander was killed while Arias was photographing Alexander in the shower.
Earlier, Arias explained that she wasn't planning to visit Alexander during her roadtrip from her home in California, but was convinced by him to spontaneously take a detour to his house for sex and to hang out.
"The very last time I called Travis it was kind of like, I don't know how to describe it, he had been very sweet and was guilting me and making me feel bad that I was taking this big trip without going to see him," Arias said this afternoon.
"When I called him last time it was just like all right, I'm going," she said. "(Sex) was our thing at that time. I wasn't going to go there, stay the night and not do that."
Arias' attorney, Kirk Nurmi, asked her repeatedly on the stand if Arias brought a gun or knife with her on the roadtrip and to Alexander's house. She said that she did not.
She also denied a series of allegations made by the prosecution that she dyed her hair, rented an inconspicuous car, borrowed gas cans, turned off her cell phone, and switched money around her bank accounts as she left for Alexander's house because she was planning to murder him when she got there.
Arias said that her hair remained the same color, auburn-brown, throughout May and June, that she rented a car because her own car was not stable enough for highway travel, that she requested a white car instead of a red one because police pull red ones over more often, and that she transferred money to a business banking account for a tax write-off to classify it as a business trip.
The testimony about the road trip and Arias' planning could be key to the jury as they decide whether the killing was pre-meditated, as the prosecution claims. Arias could face the death penalty if convicted of murder with aggravating factors such as pre-meditation.
Arias said that she "didn't sleep at all last night" before testifying about the dramatic incident today. Her comment was stricken from the record.
Arias also described a barrage of threatening text messages sent by Alexander in which he told her he would exact "revenge" on her soon and called her a "sociopath."
She told the court that Alexander's temper would make her "cower."
The messages show a growing discord between the pair in April 2008, less than two months before Arias killed Alexander.
"Do not call back," Alexander wrote in one message read aloud in court today. "I'm sick of you playing stupid and dealing with your childish issues. Bitter feelings are brewing in me for you, and if it keeps up I fear I will have a genuine dislike for you before I have a revenge."
"You don't care about anything that doesn't involve you, and I'm sick of it, and I don't want to deal with any of it," he said. "It's wearing me out and if it continues, just like I have to give you motivation to tell me the truth I'll give you motivation to quit screwing with me," he said.
In her time on the stand, Arias has described increasingly aggressive behavior from Alexander, who would show his "wrath" by kicking her in the ribs, cursing at her, and calling her names when they argued. One attack broke one of her fingers, Arias said, showing the court a permanently bent finger.
In one text message conversation, Alexander threatens Arias with "punishment." She explained on the stand that Alexander became obsessive about the identity of a stranger who told Arias that Alexander was cheating. A woman dining at the restaurant where Arias worked allegedly stopped her, identified herself as Marie, and told Arias about Alexander and another woman. Arias said she never learned the woman's identity.
"After tomorrow it's going to be really bad for you. It's time to spit it out," read one text message from Alexander about the woman's identity.
"I promise you the punishment will be better than the lie," read another.
The threatening texts and aggressive behavior drove Arias to move away from where Alexander lived in Mesa, Ariz., back to her hometown of Yreka, Calif., she said.
"I told him we need to spend more time apart, but not to get him out of my life. I wanted us to be able to have a friendship," she said.
But Alexander continued to have explosive reactions in their relationship, especially when he found out she was spending time with another man or sending messages to a romantic interest online.
"At this point it was just pure wrath," she said.
The testimony comes as the trial enters its eighth week in Phoenix. The prosecution has laid out its argument accusing Arias of killing Alexander, her former lover, in a jealous rage that left him with 27 stab wounds, a slashed throat, and two bullets in his head. They say the murder was premeditated and that Arias lied about her behavior until she was cornered by evidence, and then changed her story to killing him in self-defense.
Arias' attorneys are attempting to convince the jury that Alexander was a controlling, abusive "sexual deviant" who used Arias as his "sex slave."
