Death of Atatiana Jefferson: Former officer Aaron Dean sentenced to 11 years, 10 months, 12 days following manslaughter conviction

Dean opted to have sentencing come from the jury, instead of Judge George Gallagher.

FORT WORTH, Texas — After a day of character testimony and more than 13 hours of deliberation, a Tarrant County jury has sentenced former Fort Worth officer Aaron Dean to 11 years, 10 months and 12 days.

Dean was convicted of manslaughter in the 2019 shooting death of Atatiana Jefferson on Thursday, Dec. 15. 

The jury heard from several witnesses from both the prosecution and defense. After more than 13 hours of deliberating, the jury returned with a sentence Tuesday.

Dean had opted to have sentencing come from the jury instead of Judge George Gallagher.

In closing arguments Monday, prosecutors told the jury not to forget the victim, Jefferson, when deciding if Dean should go to prison or get probation for killing her. 

“You are judging him for what he did. You are holding him accountable for the choices he made and now you do have to ask yourself what is Atatiana’s life work,” said Prosecutor Dale Smith. 

Smith also became emotional describing Jefferson’s last moments in front of the jury. 

“When Atatiana was taking her last breaths on the floor in front of her nephew gasping for air… struggling to live and he [Dean] stood over her and he provided no aid — not attempting to do anything,” said Smith. 

Defense attorneys say Dean was acting in self-defense because he saw Jefferson with a gun pointed at him. 

“There’s nothing to gain by sending this man to the penitentiary,” said defense attorney Bob Gill.

Gill pushed the jury for probation during his closing arguments and at one point had Dean stand up. 

”Ladies and gentlemen this is Aaron Dean. This is the man you will pass judgement on in a few minutes,” Gill said. “He’s a good man, he’s a very good… We’re asking that you take into consideration all of those good qualities that you heard about him.”

Trial and sentencing recap

The sentencing phase for former Fort Worth officer Aaron Dean began Friday morning after a Tarrant County jury found him guilty of manslaughter Thursday afternoon. 

Dean was taken into custody and transported to a Tarrant County jail following the reading of the verdict.

As a result of the verdict, Dean faced two to 20 years in prison.

If the jury had sentenced Dean to 10 years or less and recommended that it be probated, Judge Gallagher would have to grant it. 

If the sentence was more than 10 years, Dean couldn’t get probations and he couldn’t get an appeal bond, according to WFAA investigative reporter Tanya Eiserer.

The murder trial began on Monday, Dec. 5. 

Several witnesses for both the prosecution and defense took the stand during the trial, 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

The verdict was reached after five days of testimony and more than 13 hours of deliberation.
