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 is 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.
R.D. Williams of Amarillo, Texas, didn't have the luxury of a short drive across town.
"It's 10 hours nonstop, two times to fuel up. I didn't bring no extra gas cans," Williams said, making a joke about a key argument in the case.
What could happen to Arias is anyone's guess.
If the jury's hung, she could face a retrial.
The prosecution, naturally, would like to see a first-degree murder conviction, as its case has revolved around Arias premeditating the killing. If convicted on this charge, Arias will face a mini-trial of sorts to determine if she killed Alexander cruelly and knew he would suffer.
A first-degree murder conviction could mean execution unless a jury grants her leniency, in which case she would get life in prison and may be eligible for parole for at least 25 years.
If the prosecution can't prove premeditation, Arias could still be convicted of second-degree murder, commanding 10 to 22 years in prison. The jury can also decide that Arias killed Alexander recklessly or that he attacked her. She'd then be convicted of manslaughter.
Lastly, the jury could find her not guilty or determine that she acted in self-defense and that her actions were reasonable.
