Aaron Dean testifies in his defense Monday at his murder trial in the death of Atatania Jefferson.
CNN  — 

A jury began deliberations Monday on a sentence for the former Texas police officer who was convicted of manslaughter last week for shooting Atatiana Jefferson in her own home in 2019.

Aaron Dean, who is White,  faces up to 20 years in prison for the conviction. Jefferson was Black.

He had pleaded not guilty to murder, a charge which carried a possible sentence of five to 99 years. Jurors were instructed Wednesday to also consider the lesser included offense of manslaughter. The sentencing phase begins Friday, CNN affiliate WFAA reported.

Dean, in a gray suit, showed no emotion as the verdict was read.

Members of Jefferson’s family were expressionless in the courtroom as the judge announced the verdict, WFAA reported. There was no immediate comment from family members.

“We’re glad there was a guilty verdict. That’s progress,” the Rev. Crystal Bates, a minister and activist, told WFAA outside court.

“But there’s so much work to be done… How he is sentenced is going to send a message not only to him but to other law enforcement to not be so trigger happy when you see somebody of color.”

Defense attorneys had said Dean fired in self-defense, but prosecutors argued there was no evidence he saw a gun in the woman’s hand before firing through a bedroom window.

Jefferson’s 11-year-old nephew, who was with her at the time, and Dean’s police partner – who responded with him to what they believed was a burglary – were the primary witnesses to the shooting and testified at trial. Dean took the stand and said he fired at Jefferson because she pointed a gun at him.

The verdict comes more than three years after the deadly encounter in which Dean and his partner responded to Jefferson’s house around 2:25 a.m. on October 12, 2019. They arrived at her house after a neighbor called a nonemergency police line to report that her doors were open.

Trial testimony, which touched on fraught issues of race, police violence, gun rights and body-camera footage, began on December 5.

Aaron Dean arrives at court for closing arguments on Wednesday.

The verdict was announced after jurors deliberated for more than 13 hours, reported WFAA. The manslaughter conviction of a police officer who was on duty is a first in Tarrant County, the station reported.

Jurors got the case Wednesday afternoon following closing arguments in which the state portrayed Dean as a power-hungry former cop whose preconceived notions about the neighborhood where Jefferson lived tainted his conduct the night of the shooting.

The defense countered that Dean fired his weapon in self-defense while fearing for his life in what attorneys said was a tragic accident but not a criminal act.

Dean resigned days afterward and was arrested and charged in the killing of Jefferson.

“If you can’t feel safe in your own home, where can you feel safe?” Tarrant County Prosecutor Ashlea Deener told jurors in closing arguments on Wednesday. “When you think about your house, you think about safety. It’s where you go to retreat, to get away from the world.”

Dean, the prosecutor said, had a “tremendous amount of power” when he put on his uniform.

“When you put on that badge and you put on that uniform you say you’re going to serve and protect us all. That means her too,” Deener said of Jefferson.

“And the Fort Worth Police Department – those officers that do serve and protect us, that don’t have those preconceived notions, that did a thorough investigation in this case – are ashamed that they ever called somebody like him a brother in blue,” she added, referring to the former officer.

Defense attorney Bob Gill told jurors Dean feared for his life as he peered through the bedroom window that night.

“The state cannot prove to you beyond a reasonable doubt that this was not self-defense,” Gill said. “It’s tragic, but is not an offense under the state of Texas.”

Holding his hands in the air to show the size of the gun Dean claimed he saw through the bedroom window, Gill told the jury: “What is immediately more necessary than having a handgun stuck in your face? And you have heard from several people, starting with Aaron, that that handgun was this big when he saw it.”

Gill added, “If you believe that Aaron was legitimately defending a third person, and reasonably defending a third person, or if you had a reasonable doubt about whether he was doing such, then you are to acquit Aaron. And you don’t have to agree that it was self-defense or defense of a third person. You just have to decide in your mind that he reasonably believed he was doing one of those two things.”

Officer testified he saw barrel of gun pointed at him

Dean testified last Monday that he fired at Jefferson because she pointed a gun at him.

“As I started to get that second phrase out, ‘Show me your hands,’ I saw a silhouette,” the former officer said. “I was looking right down the barrel of a gun, and when I saw the barrel of that gun pointed at me, I fired a single shot from my duty weapon.”

Dean said he had his weapon out because he believed the home was in the midst of being robbed. He fired at her through the window “because we’re taught to meet deadly force with deadly force. We’re not taught that we have to wait,” he said.

In cross-examination, however, Dean admitted many of his actions that night were “bad police work,” including firing without seeing her hands or what was behind her, failing to tell his partner he saw a gun and rushing into the home without fully ensuring it was safe.

“You’ve got another fellow officer from the Fort Worth Police Department entering a home which you have determined to be a burglary in progress with a possible armed assailant, and you didn’t think to tell your partner, ‘Hey there’s a gun inside?’” prosecutor R. Dale Smith asked.

“No,” Dean said.
