Michael Dunn will have to wait another day -- at least -- to learn his fate.
He is charged with first-degree murder in the November 2012 death of 17-year-old Jordan Davis, one of four black teenagers who were in an SUV shot by Dunn -- who is white -- in violence that flared from an argument over loud music.
The Jacksonsville, Florida, jury in Dunn's case deliberated all day Friday, only to send a message to the judge shortly before 7 p.m. that they had "reached a wall for the evening." In other words, for the second straight day they hadn't reached a decision.
With that, Judge Russell Healey gave them the OK to head back to their hotel so that they could return for deliberations around 9 a.m. Saturday.
"This is one admirable group," Healey told the court shortly before dismissing the jury. "They are clearly taking this thing as seriously as they should. And I couldn't be more proud of them for how hard they are working."
This announcement capped a relatively uneventful day Friday, after what had been an emotional and eventful trial.
The closest thing to news came shortly before 5 p.m., when Judge Healey answered a question from the jury: Is it possible to not reach a verdict on one count and reach a verdict on other counts?
To which Healey responded: Yes.
Prosecutors contend that Dunn's firing into the SUV equates to an act of murder. In addition to that count, Dunn also has been charged with three counts of attempted murder. If found guilty, he faces up to life in prison.
A "comprehensive public safety plan" has been established ahead of a verdict in the case, according to the Duval County joint information center handling the Dunn trial.
"All contingencies have been planned for," the Duval County statement said. "We will not discuss the specifics of any security plan. We will continue to protect the rights of those who choose to peaceably demonstrate."
Trial draws comparisons to another Florida case
The Dunn case has drawn parallels to the trial of George Zimmerman in the killing of teenager Trayvon Martin, which like the current trial had racial overtones and claims of self-defense.
Dunn defense attorney Cory Strolla told CNN's Chris Cuomo on Friday that the Zimmerman and Dunn cases aren't so similar in his mind.
There was a physical confrontation between Zimmerman and Martin, and police gave Zimmerman the benefit of the doubt about defending himself, Strolla said.
"My client did not wait to become that victim; my client did not wait to either get assaulted by a weapon or have someone potentially pull a trigger," he said.
Unlike the Zimmerman case, police rushed to charge Dunn with murder, the defense attorney said.
"They already made up their mind before they even had the evidence basically looked at and put together," he said.
Even though a weapon was never found, Strolla maintains the youths could have had one. Dunn felt threatened and acted to defend himself, he said.
"Now, does it sound irrational? Of course it sounds irrational. But have you ever been in that situation?" Strolla said.
Jurors on Thursday asked to see surveillance video from the gas station where Dunn shot Davis.
The video contains 20 minutes of footage from multiple angles, though a shorter version showing only one angle was slated to be shown in court.
In closing arguments Wednesday, prosecutors said inconsistencies between Dunn's words and actions undermined his assertion he acted in self-defense when he fatally shot the teen.
His attorney countered the state failed to prove beyond a reasonable doubt his client was guilty. He pleaded with jurors to find Dunn not guilty.
In testimony Tuesday, Dunn said he fired in self-defense after the teen threatened him with a gun.
