Here are the possibilities for Arias:
• If the jury unanimously agrees on death, then Arias will be sentenced to spend the rest of her life on death row before she is executed by lethal injection.
• If the jury instead unanimously agrees to life, then the judge decides between life with possibility of parole or natural life.
• If this jury is unable to reach a unanimous decision, death is taken off the table and the judge must then decide between life with possibility of parole or natural life.
The jury does not have a say in whether Arias is given the possibility of parole, its job is limited to the decision of life or death.
