The defense rested its case after a day and half of testimony.
FORT WORTH, Texas — After five days of testimony in the murder trial of former Fort Worth officer Aaron Dean in the 2019 death of Atatiana Jefferson, the defense has rested its case.
Testimony resumed Tuesday with the defense calling law enforcement professor Jay Coons to take the stand as a “use-of-force” expert witness.
Throughout his testimony, Coons told the jury he believed Dean and his partner Officer Darch exemplified “good police work,” in responding to Jefferson’s home on Oct. 12, 2019.
“They didn’t know what they had,” Coons said. A statement he repeated several times in describing his observations of how Dean and Darch conducted themselves during the investigation at Jefferson’s home.
The nature in which they approached and the observations they were making were “perfectly fine,” said Coons.
“Officers’ Dean’s actions that night – and yes this is a terrible event, there’s nothing good about this. But his actions as a police officer were reasonable in what he was doing,” Coons testified.
In cross-examination, prosecutor Dale Smith questioned Coons over general orders and Dean’s testimony Monday, in which the former officer said he that he was responding to a possible burglary.
When Coons was asked if Dean and Darch should’ve called for backup, according to general orders, Coons didn’t directly answer yes or no. Yet, he did say “hypothetically” if Dean came to the conclusion that it was a burglary-in-progress, there should have been a call for backup.
Smith was also trying to hammer the fact that Coons was not a neurologist in hopes of discrediting his testimony over Dean’s thought process in responding to Jefferson home and leading up to the moments when he decided to pull the trigger, shooting and killing Jefferson.
Following nearly three hours of testimony from Coons, the defense rested. And the judge called for a lunch break for jurors.
When the jury returned, the prosecution called a rebuttal witness to the stand, forensic analyst and instructor Jonathyn Priest.
When questioned over Dean’s and Darch’s tactical response to Jefferson’s home, Priest said they had two better options: knock and announce or back away from the home and call for backup.
“My opinion is that they shouldn’t have left the front door,” said Priest.
On Monday, Dean took the stand in his own defense, stating that the jury needed to “hear from me and hear the truth.”
Dean faced hard questioning from the prosecution on his background, his police training and if he would have graded his actions on Oct. 12, 2019, highly.
While recounting the events that led up to the deadly shooting, Dean became visibly shaken and cried.
“I know you’re crying now, but you weren’t crying when you decided not to administer CPR to Atatiana,” prosecutor Dale Smith said to Dean during cross-examination.
Smith hammered Dean over the mistakes 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.
When Smith asked Dean what grade he’d give himself for his actions. Dean answered that he’d give himself a B.
Following Dean’s testimony, a video expert took the stand for the last few hours of court on Monday.
Forensics video expert Grant Fredericks testified on the limitations of the body camera Dean wore the night of Jefferson’s death, the camera’s field of view and the camera’s ability to focus from light to dark.
