After more than seven hours of deliberations, jurors still haven't decided whether Jodi Arias will live or die.
The Arizona jury sent out a note Wednesday morning saying its members couldn't agree.
Judge Sherry Stephens told them to try again and ordered them back into the jury room.
It was another unexpected turn in the dramatic, high-profile murder trial, which has lasted for months, sparked a media frenzy and drawn spectators who line up for courtroom seats.
Earlier this month, the same jurors took less than two hours to decide that Arias was "exceptionally cruel" in 2008 when she stabbed ex-boyfriend Travis Alexander 29 times, slit his neck from ear to ear and shot him in the face.
They pronounced her guilty of first-degree murder two weeks ago after 15 hours of deliberations.
Now, the jury is weighing whether Arias, 32, should get the death penalty.
After jurors told Stephens they were stuck on Wednesday, the judge encouraged them to listen to each other, pinpoint areas of agreement and disagreement and ask for further guidance if they need it.
It's an approach often described as a "dynamite charge," used by judges to blast open logjams in deliberations and help jurors reach a verdict.
It's unclear whether her advice worked. After Stephens ordered them to continue their discussions, jurors deliberated for more than four more hours, then went home for the day.
The jury's decision must be unanimous for Arias to be sentenced to death. In the case of a deadlock, a new jury would be chosen for this phase of the trial.
A plea for mercy
A path of heartbreak, violence, lies and confessions has led Arias to the Phoenix courtroom where her life is now in a jury's hands.
On Tuesday, she pleaded with jurors to spare her.
It was a stark reversal from two weeks ago, when she told a journalist she preferred death to life in prison.
"I believe death is the ultimate freedom, so I'd rather just have my freedom as soon as I can get it," she told KSAZ shortly after her conviction.
But her family implored her to change her mind, she told KSAZ late Tuesday. Now she wants to spare them further heartbreak, she said.
"One of my cousins really drove it home for me and told me how much it would affect them, if I did anything to myself," she said.
Her mother pleaded with her, she claimed. "Please don't give up; please don't give up," Arias said she told her.
Her life seemed to pass before her, as she delivered a slideshow presentation -- mostly of family photos -- to the jury on Tuesday. It started off with pictures of her as a toddler wearing pigtails and showed several images from holidays and vacations with family members.
She read a prepared statement for nearly 20 minutes, at times crying.
Arias told jurors that she had been a victim of abuse as an adult and as a child. She had claimed she killed Alexander in self-defense after he hurt her, something evidence failed to substantiate.
She called his murder "the worst mistake" she'd ever made, "the worst thing I've ever done." She couldn't have imagined herself capable of such a grisly crime, Arias told the jury.
"But I know that I was," she said. "And for that I'm going to be sorry for the rest of my life -- probably longer."
