Death of Atatiana Jefferson: Jury reaches verdict in Aaron Dean sentencing

The former Fort Worth police officer faces two to 20 years in prison.

TARRANT COUNTY, Texas — After more than 13 hours of deliberation in the sentencing for former Fort Worth officer Aaron Dean, a Tarrant County jury sentenced him to 11 years, 10 months and 12 days.

The jury found him guilty of manslaughter in the 2019 shooting death of Atatiana Jefferson last week. 

The sentencing phase resumed Tuesday morning, after the jury deliberated for more than seven hours Monday. 

Dean's guilty verdict was reached after five days of testimony and more than 13 hours of deliberation. He was then taken into custody and transported to a Tarrant County jail. 

Now, the former officer faces two to 20 years in prison. 

If the jury sentences Dean to 10 years or less and recommends that it be probated, Tarrant County Judge George Gallagher will have to grant it. If the sentence is more than 10 years, Dean cannot get probations and he cannot get an appeal bond, according to WFAA investigative reporter Tanya Eiserer. 

The prosecution and defense held closing arguments Monday. 

The prosecution posed the question: What is Atatiana Jefferson's life worth? 

"Her life is worth so much more than a probation sentence," Prosecutor Ashlea Deener said. "This family, her memory, her legacy, this community deserves more." 

The defense pushed for the jury to take their emotions out of it and to do what was fair and just. 

“That’s really what this case is worth,” Gill said about giving Dean probation.  

Gill went on to say Dean was a good man, referencing character testimony given by family and church friends. 

"He’s a God-fearing, law abiding citizen of our county," said Gill. 

The prosecution was given the final rebuttal closing argument. 

“15 minutes a month,” is that really what her life is worth, Smith said in reference to the jury possibly sentencing Dean to probation. 

“She deserved better from that defendant,” Smith said. “And she deserves a sentence from you... Give him the maximum." 

Sentencing phase testimony 

As the punishment phase proceedings began around 8:20 a.m. Friday morning, the prosecution called Dr. Kyle Clayton, a psychologist who conducted Dean's employment personality evaluation, to the stand to be vetted ahead of the jury being brought in.  

But during this process, Judge Gallagher locked the courtroom after learning Fort Worth City Councilman Chris Nettles violated a gag order in the case. Nettles now has a show-cause hearing on Jan. 4 at noon, for three counts of contempt of court for interviews he gave following Dean's conviction and a press release. 

Judge Gallagher also called Fort Worth Mayor Mattie Parker to the courtroom and said she was too in contempt of court for violating the gag order following her release of a written statement. She too will face a hearing. 

Once Judge Gallagher reopened the courtroom, proceedings in the sentencing phase resumed, and Dr. Clayton was called to testify on the prosecution's behalf. 

Clayton, one of the psychologists used by the Fort Worth Police Department, said he conducted Dean's pre-employment psych evaluation on March 29, 2017. 

Clayton said after interviewing Dean, he identified Dean's problem areas -- which included grandiosity, interpersonal difficulties, dominance and superiority. 

Clayton also said he believed Dean had a narcissistic personality and felt Dean would not be able to work well with others, and he failed him after his evaluation.

"He was not psychologically suitable to be a Fort Worth police officer," Clayton told the jury. 

In cross-examination, the defense pointed out that three other psychologists said Dean was fit for duty. 

Following Clayton's testimony, the prosecution called a woman who filed an assault charge against Dean for a 2004 incident while attending UTA. 

She described the incident for the jury, saying, "He took his finger and touched my right breast and tracing his finger over my breast." 

She said she told Dean she was uncomfortable, he stopped and told her not to tell anyone what happened, as she started leaving the room. She told the jury she gave a verbal report and written statements to campus police.

Dean pleaded no contest and was given a citation by Arlington police. 

In cross-examination, the defense asked about "social adjustment issues" due to her and Dean being homeschooled. 

The witness denied that being homeschooled played a role in her adjusting to society. She was then called down from the stand. 

The prosecution then called Jefferson's oldest brother, Adarius Carr, to the stand. In an emotional showing, Carr described his sister and the last time he saw her before she was shot and killed by Dean. 

After Carr's testimony, the prosecution rested its sentencing case. 

Dean’s defense team then called a man he went to church with who called him noble and a servant, as a probation officer to try to convince the jury that would be a fitting punishment. 

The defense then called a training officer, followed by Dean's mother, Donna Dean. 

“He wanted to make a difference in people’s lives and help people,” when asked what Dean said when he told his family that he wanted to be a police officer.

The defense called Dean's younger brother and sister to the stand to further drive home that they believe Dean is humble and a rule follower. 

Once the defense rested, the prosecution called rebuttal witness, Jefferson's eldest sister Ashley Carr to the stand. Ashley talked about the relationship Jefferson had with her nephew Zion, and how Jefferson's death has affected Zion over the last three years. 

Ashley said Zion is having panic attacks and has a therapist and school workers who help him. 

As Ashley stepped down from the stand, both sides rested. 

Judge Gallagher then met with both the prosecution and defense, concerning closing arguments and deliberations. Both side opted to begin closings and deliberations on Monday, Dec. 19.  

Trial recap

The murder trial began on Monday, Dec. 5. 

Several witnesses for both the prosecution and defense took the stand, including emotional testimony from Atatiana Jefferson's now 11-year-old nephew Zion Carr, the neighbor who dialed 911 to request a welfare check at Jefferson's home, Dean's former partner and Dean himself. 

Dean testified that he saw someone point a gun at him from the other side of the window, and his attorneys argued the shooting was self-defense.

Dean was visibly shaken when he started to testify about what happened. He told the jury he started shouting commands for the silhouette to “put up your hands, show me your hands.”

Said Dean: "I started getting that second command out, I saw the barrel of the gun, and when I saw that gun pointing at me... I shot a single shot from my service weapon."

Prosecutors have argued that Dean violated his training and general orders, and did not identify himself as a Fort Worth police officer.

Prosecutor Dale Smith hammered Dean over the mistakes allegedly made in responding to the call at Jefferson’s home, especially driving home the fact that he did not see the hands of the ‘silhouette’ in the window nor identify to his partner there was a gun, or immediately start CPR on Jefferson.

“I know you’re crying now, but you weren’t crying when you decided not to administer CPR to Atatiana,” Smith said to Dean.

After five days of testimony, closing arguments were held on Wednesday, Dec. 14. 

Dean's defense attorney Bob Gill opened by saying, “A tragedy doesn’t always equal a crime; it doesn’t always equal a law violation." 

Gill said Dean had the right to self-defense and that Jefferson lost her rights the moment, "She [Atatiana] pointed a firearm at a Fort Worth police officer... the rights stop there," Gill said. "It's a crime and it's an unlawful act."

Both prosecution attorneys had closing statements. 

Prosecutor Ashlea Deener opened. “The power you have today is to hold him responsible, it’s to tell them [Atatiana’s family] that it all wasn’t in vain, it’s to say that she [Atatiana] matters. They matter, eastside matters. To say that we protect everyone."  

Prosecutor Dale Smith addressed the jury in a rebuttal closing argument. Smith told the jury, Jefferson's "only crime was love and protection for her nephew, not pointing a gun at a Fort Worth police officer.”

In closing, Smith said, “A tragedy, an accident that’s spilling your milk at breakfast… This is murder." 

WFAA will stream the trial on multiple platforms -- including WFAA+, YouTube and wfaa.com. (WFAA+ is available on Roku and Amazon Fire.)
