Updated at 5:06 p.m.: Revised to reflect that the jury left for the day.

The fate of Amber Guyger is in the jurors' hands.

During closing arguments, her defense said "a series of horrible mistakes" led to her shooting Botham Jean out of fear for her life. But prosecutors said claims of self-defense don't apply in Guyger's case because Jean was not a threat. They said that she had other options besides killing him and that she acted unreasonably by failing to notice she wasn't at her own apartment.

Guyger, 31, has said she mistook Jean's apartment for her own on the night of Sept. 6, 2018, and fatally shot 26-year-old Jean, thinking he was a burglar.

The jury began deliberating Monday afternoon, after closing arguments. They retired for the day just after 5 p.m. and will resume deliberations Tuesday morning to decide whether Guyger is guilty or not guilty of either murder or manslaughter.

Prosecutor Jason Fine began the state's closing arguments by reading something Guyger said during her testimony: "I never want anybody to have to go through or even imagine going through what I felt that night."

"Are you kidding me?" he said, crumpling up the paper he was reading from and tossing it in the trash. "That is garbage."

He urged the jurors to think from Jean's perspective — for them to imagine coming home from a long day and sitting down with a bowl of ice cream when they're shot by an intruder.

He said Guyger missed five key clues when she was standing at Jean's door: the apartment sign, his red door mat, the blinking red light signaling her key wasn't recognized, the lack of a whirring motor sound from the key and the feeling of walking from concrete onto carpet.

"I mean, my God. This is crazy," Fine said. "It was unreasonable — she should've known she was in the wrong apartment."

A juror smiled slightly as Fine spoke incredulously about how Guyger's senses failed her that night.

During their deliberations, the jurors may consider the "castle doctrine" — the right to defend yourself in your own home. The defense has said it applies to Guyger because she believed she was in her apartment.

Fine sounded exasperated as he told the jury it didn't apply to Guyger — it would have applied to Jean, but he was unarmed and there is no evidence he tried to defend himself.

"Who does castle doctrine protect? Homeowners. It protects homeowners against intruders, and now, all of a sudden, the intruder is trying to use it against the homeowner. What are we doing?" Fine asked, sighing and shaking his head.

He said Guyger decided before she went inside Jean's apartment that she would "execute" whoever was in there. Had Guyger retreated, Fine said, Jean would still be alive.

Guyger's parents and sister were in the courtroom for the first time Monday. When Fine told the jury that "nobody had to die" that night and that Guyger acted unreasonably, Guyger's mother looked down.

Fine implored the jurors to "do the right thing," telling them they are the voice of the community.

"I believe that y'all will do the right thing, that y'all will follow your oath, that y'all will follow the law, apply it to these facts, and render the only, only true verdict, the only just verdict," Fine said, "and that is that this defendant murdered an innocent young man in his home."

Defense attorney Toby Shook told the jury it could not decide whether Guyger is guilty based on "emotion and sympathy."

"That's hard, especially in a case like this," he said. "You'll never see a case like this that's so tragic. So tragic."

He told jurors they had to look at the case "coolly and calmly."

Shook pointed to prosecutors' suggestion that Guyger didn't do enough to save Jean, saying it was designed to get the jury angry and emotional.

He told the jurors the "hard truth" was that no amount of first aid would have saved Jean. One juror twisted her chair from side to side as he spoke.

"He couldn't survive because of the wound he received," Shook said. "CPR wasn't going to help."

Then he pointed to two texts Guyger sent to her partner, Martin Rivera, while she was still on the phone with 911.

"You can hate her for sending that text. You can be angry with her. You can hate her, but you can't convict her" based on emotion, Shook said.

He said Guyger "made a series of horrible mistakes" the night she killed Jean.

Robert Rogers, another of Guyger's attorneys, said prosecutors failed to "do their duty" and show that Guyger wasn't reasonable in her actions.

"We actually, even though we have no duty, we showed you how this was a reasonable mistake," he said.

"The state, what did they bring you? Sexting and speculation," Rogers continued. "Everything that they have done has been to try to distract you and trick you from looking at the law in this case because they know that if you apply it correctly, that Amber Guyger is not guilty."

In his rebuttal, lead prosecutor Jason Hermus said that the defense's argument of self-defense doesn't apply in this case and that Guyger had other options available when she thought she was at her apartment, confronted by a burglar. A juror nodded in response.

Hermus pointed out Guyger is trained to get in a position of concealment and cover in such situations. The former officer could have called for assistance, but Hermus argued she made the decision to kill while outside Jean's door.

"She decided from outside, from a position of safety, that she was going to engage what she called 'the threat,' " Hermus said.

Hermus said Guyger acted unreasonably during the shooting, particularly by missing several details that a trained officer should have noticed. He held up Jean's red doormat and told the jury she failed to notice it.

"You can't miss this," Hermus said. "And she walked up to it and stood on top of it."

In his final remarks, he spoke directly to Guyger:

"By God, in Dallas County, Texas," Hermus said, pointing a finger at Guyger, "there will be a consequence for you shooting an unarmed, defenseless man."

After the jury left the courtroom, Hermus walked over to Allison Jean, embracing her and kissing her cheek.

She and her husband looked straight ahead as they watched the attorneys make closing arguments. They looked down when photos of first responders trying to save Jean's life filled the large screens in the courtroom.

But afterward, near the elevators, Allison Jean looked as though she could barely contain her emotions as her face crumpled while attorneys and family members comforted her.

What's the difference between murder and manslaughter?

Murder: A person commits an offense if he:

intentionally or knowingly causes the death of an individual;

intends to cause serious bodily injury and commits an act clearly dangerous to human life that causes the death of an individual; or

commits or attempts to commit a felony, other than manslaughter, and in the course of and in furtherance of the commission or attempt, or in immediate flight from the commission or attempt, he commits or attempts to commit an act clearly dangerous to human life that causes the death of an individual.

In Texas, murder carries a punishment of five to 99 years or life in prison.

Manslaughter: A person commits an offense if he recklessly causes the death of an individual.

In Texas, manslaughter carries a punishment of two to 20 years in prison.

Texas' 'castle doctrine'

Under Texas’ “castle doctrine” or “stand your ground” law, people have the right to use deadly force — without first retreating — to protect themselves or their property if they:

Reasonably believe the deadly force is immediately necessary,

Have the right to be present at the location where the deadly force is used,

Did not provoke the person against whom the force is used, and

Were not engaged in criminal activity at the time the force is used.
