Arias and Alexander met in 2006 at a business convention in Las Vegas. Arias became his girlfriend two months later, she testified. Alexander's bloodied body was found in his Mesa, Arizona, home in June 2008.
Arias says that the pair broke up in 2007, and Alexander began seeing other women. There were claims that Arias would stalk him, peering in his windows at times. Still, he and Arias continued to hang out on several occasions until -- disenchanted Arias says -- she moved back to Northern California. They continued to communicate.
Alexander's naked body was found crammed in a stand-up shower after he missed two appointments, prompting friends to go to his house. Arias was charged with murder, at first denying the claims and later admitting she killed him in self-defense. Alexander's body was found with 27 stab wounds in the back and torso, a shot in the head, and his throat slit from ear to ear.
Arias spent 18 days on the witness stand recalling the minutiae of her allegedly abusive relationship with Alexander but claimed to have no recollection of the actual attack.
On February 28, 2013, prosecutor Juan Martinez asks Arias about a photograph she took of Alexander in the shower moments before he was killed. Prior to Alexander's killing, Martinez said, Arias stole her grandparents' .25-caliber pistol, rented a car in Redding, California, turned off her cell phone and brought along cans of gas so there would be no record that she was in Arizona.

Arias talks to defense attorneys Willmott, left, and Kirk Nurmi during her trial on April 3, 2013. Arguing the prosecution's position that Arias was obsessed with Alexander and stalking him, Nurmi said it didn't add up because Arias was active on a Mormon dating site. "Jodi ... wasn't so locked in on Travis that she wasn't looking for other men," Nurmi said.
Prosecutor Juan Martinez makes closing arguments on May 2. Throughout the trial, prosecutors said Arias manipulated people as well as the evidence.
