Day four of the Jodi Arias sentencing retrial continued as prosecutors presented evidence of ways Arias tried to deflect blame for the murder of her ex-boyfriend.

The lead detective in the murder case took the witness stand on Monday in the Maricopa County Superior Court as prosecutor Juan Martinez walked the jury through a sequence of events that occurred after Arias brutally murdered her lover, Travis Alexander, in 2008.

Martinez made note of Arias' multiple attempts to cover up the murder by highlighting the emails, texts and phone calls she made after she killed Alexander in his suburban home.

In one text, she wrote, "I haven't heard back from you. I hope you're not upset," reports WJHL.

The jury also heard portions of Arias' initial taped interrogation, in which she said, "I did not hurt Travis. I would not do that to him."

In response, Mesa Police detective Esteban Flores said, "There is so much evidence in the house. So much and it all points to you."

He later added, "Jodi, Jodi. This is all over. You need to tell the truth."

Although Arias never confessed to the crime in the video, she told at least three different stories about what happened to Alexander, including one where she claimed people dressed as ninjas broke into the home and killed Alexander after he threatened.

"Obsessed is the word I heard," Flores told Arias during one videotaped interrogation, according to USA Today. "Fatal attraction: I don't know how many times I heard that."

According to medical examiners, Arias stabbed him 27 times, primarily in the back, torso and heart in his Phoenix home in 2008. She also slit Alexander's throat from ear to ear, nearly decapitating him, and shot him in the face before she dragged his bloodied corpse to the shower.

The aspiring photographer was convicted of first-degree murder in May 2013, but the jurors failed to reach a unanimous decision on her sentencing. As a result, the retrial will determine whether she should be sentenced to death, life in prison, or life with a chance of release after serving 25 years.
