Defense attorney Jennifer Willmott has said Arias was the victim of a controlling, psychologically abusive relationship and that Alexander considered Arias "his dirty little secret."
Before Arias killed her ex in self-defense, Willmott claimed, she was subjected to rough vaginal sex. After she dropped Alexander's new camera, he became violent, the defense said, and had Arias not defended herself, investigators would've found Arias, not Alexander, dead in the bathroom.
Arguing the prosecution's position that Arias was obsessed with Alexander and stalking him, another defense attorney, Kirk Nurmi, has 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.
As for the allegation that Arias attempted to surreptitiously slip in and out of Arizona without a trace, Nurmi pointed out that Arias went to the Redding, California, airport to rent her car for the trip.
"An airport with security cameras and security all around," the defense attorney said, "not some rental car agency on the outskirts of town -- an airport. That doesn't make any sense if you're on a covert mission."
Nurmi also questioned the merit of the prosecution's gas can argument, saying Arias could have avoided a paper trail simply by paying with cash. She didn't need cans, he said.
Did Arias change her story? Sure, Nurmi said, but that's not what she's standing trial for.
"If Jodi Arias were accused of the crime of lying, I could not stand before you and say she's not guilty of that crime, but nowhere in your jury instructions are you asked to convict Jodi Arias of lying," Nurmi said.
If you didn't realize before, you probably see now why the case has drawn a cult following of sorts. It's rife with sex, lies and digital images, many of them naughty, and the dueling attorneys are lively -- nay, bombastic -- in their arguments.
Arias herself has been tweeting from jail -- through a proxy, of course -- criticizing HLN and Martinez, and directing followers to a website that sells art on her behalf.
For some media outlets, the case is gold.
HLN has created a show, "After Dark: The Jodi Arias Trial," which invites an in-studio and at-home audience to grade the day's arguments. Its website is flush with every facet of the case, including a photo gallery containing 180 evidence photos.
The Huffington Post has similar coverage, and CNN affiliates KPHO and KNXV in Phoenix have special trial pages on their websites.
Before you lob cries of a sensationalist media profiting off a gruesome death, realize that people are clamoring for the coverage. HLN has enjoyed a massive ratings boost since the trial began, and people drive hours to see the trial for themselves.
Spectators began lining up Friday at 1 a.m. -- more than six hours before the courthouse opened -- to get a seat, according to KPHO.
Until April 25, the public was given access on a first-come-first-served basis, but the judge changed it to a lottery system for closing arguments, the station reported.
Everardo McFarlane of Phoenix was none too happy with the change, as he was first in line Friday but didn't make the cut.
"I just hope justice is served and that at least we get our $1.6 million worth with a conviction," McFarlane told KPHO, referring to the ever-increasing taxpayer expense on the trial.
