Hours after Jodi Arias asked a jury to spare her life for killing her ex-boyfriend, Travis Alexander, the convicted killer maintained in a jailhouse interview with ABC News that it would have been "meaningless" to apologize to Alexander's family in court because no one would believe her.

Arias, 32, was convicted last week of first-degree last week for the June 2008 stabbing and shooting death of Alexander. Arias has been branded a liar by the prosecution because she initially denied killing Alexander, then claimed two years later that she killed him in self-defense.

"I think in a sense, the words, 'I'm sorry,' just seemed meaningless, especially since nobody believes what I'm saying anyway," said Arias, who in court tearfully told the family that she never meant to cause them so much pain, but she did not apologize.

Jodi Arias could become the third woman on Arizona's death row if she is sentenced to death today for murdering her ex-boyfriend, Travis Alexander.

If condemned to death row, she would likely face a long sentence, since Arizona has not executed a woman since 1930. But that long sentence would be marked by extreme isolation.

The jury that convicted Arias earlier this month is set to continue their deliberations today over whether to give Arias life in prison or the death penalty. They began deliberating at 6 p.m. ET on Tuesday.

Arias and her attorneys begged the jury to spare her life on Tuesday during Arias's allocution statement and the closing arguments, telling the jury that Arias would spend her life behind bars helping others and contributing to society.

But prosecutor Juan Martinez told the jury death is the only just punishment for the June 4, 2008 murder, in which Arias killed Alexander with 27 stab wounds, a slashed throat and a gunshot to the head.
