PHOENIX — The nearly seven-year legal saga of Jodi Arias ended Monday as a judge sentenced her to life in prison for killing her ex-boyfriend, and the victim’s sisters unleashed their pain over the 2008 murder that captivated social media with its salacious details.

Three of Travis Alexander’s sisters tearfully urged Judge Sherry Stephens to impose the harshest penalty available against Arias. They described Arias as “unrepentant” and “evil” and lashed out at her.

As Arias was leaving the courtroom, Alexander’s younger sister, Tanisha Sorenson, said loudly, “Burn in hell,” prompting her sister to try to quiet her down.

Prosecutors say Arias killed Alexander after he planned a trip to Mexico with another woman.
