Arias had her hair cut to shoulder-length for her return to the courtroom and appeared to have it dyed darker. She was wearing a new pair of nude-framed glasses - perhaps because earlier this month, a Phoenix food bank auctioned off the glasses she wore at the original trial and raised close to $1,000 for charity. Also on Tuesday, defense lawyer Kirk Nurmi began opening statements, telling jurors it was up to them to write the final chapter to the story. He warned the jury that it will see graphic evidence about the killing and relationship between Arias and victim Travis Alexander - but said she should not be executed because she is mentally ill. Prosecutor  Martinez proved his point by showing jurors a picture of Arias' victim, ex-boyfriend Travis Alexander, with his throat slit. 'This is how much she loved him,' Martinez told the jury, according to ABC. The victims' siblings were in court today along with Arias' parents and brother. Arias was convicted of murder last year but the first jury was deadlocked on whether to give her the death penalty or life in prison. That required a new jury and trial to decide her punishment. A new jury that was picked over the past several weeks will listen as the former waitress tries to make another case that her life should be spared. Four hundred people were called as prospective jurors. Many of them were cut after they said they either made up their minds about the case or knew too much to be impartial.

She left his body in his shower where friends found him about five days later at his suburban Phoenix home. She acknowledged she killed Alexander, but claimed it was self-defense after he attacked her. Prosecutors said it was premeditated murder carried out in a jealous rage after the victim wanted to end their affair and planned a trip to Mexico with another woman. Weeks after Arias was convicted, the jury failed to reach a unanimous decision on her punishment. Her attorneys have since sought, unsuccessfully, to dismiss the death penalty as an option. If another deadlock occurs, the death penalty would automatically be removed as an option, leaving a judge to sentence Arias to one of two options: life in prison or life in prison with the possibility of release after 25 years. Arias, pictured in court on January 9, 2013, must now convince the jury at her retrial that she does not deserve the death penalty for the brutal slaying of her ex-boyfriend, Travis Alexander .

At her last trial, she testified for 18 days, describing for jurors an abusive childhood, cheating boyfriends, dead-end jobs, a shocking sexual relationship with Alexander, and her contention that he was physically abusive. Her first trial drew a global following and inspired spectators to wait in line in the middle of the night to get a coveted seat in the courtroom.

Judge Sherry Stephens has shut the media and public out of nearly every hearing in the case and drawn complaints from First Amendment lawyers that she has gone too far.
