DALLAS (CBSDFW.COM) – Closing arguments concluded around 5:15 p.m. Friday in the aggravated assault retrial of former Mesquite Police officer Derick Wiley.

Wiley shot an unarmed Lyndo Jones at Jones’ pickup truck in November 2017.

A Dallas County jury will now determine if Wiley was justified in shooting Jones.

After approximately three hours of deliberations, the jury had not reached a verdict and went home for the weekend.

The first trial ended in a hung jury.

Deliberations in the retrial will resume at 9:00 a.m. Monday.

Wiley took the witness stand on Thursday and  got emotional saying he believes his actions were justified.

“I thought I was out there by myself. Can’t get on the radio. 4-5-4 hadn’t showed up. I thought I was by myself,” Wiley said on the stand.

With his body camera rolling as he approached Lyndo Jones’ truck, Wiley was yelling at him to get out and get on the ground.

While applying pressure to his back, Jones turns over and runs away.

Wiley’s defense contends had Jones complied with Wiley’s orders, they wouldn’t be here today.

“I told myself either I got to shoot him or he’s going to shoot me,” said Wiley.

Earlier in the day, the only civilian witness to this shooting took the stand, saying he believes Wiley was in trouble.

“I saw Mr. Jones struggling to gain control of Officer Wiley’s weapon,” said witness Henry Leaverton.

The state’s use of deadly force expert says the body cam video – which the Dallas County DA’s office says is prime evidence he violated his police authority – documents proper policing until Wiley decides to shoot Jones.

“Did Lyndo Jones pose a threat to Officer Wiley that he had to use deadly force? No,” said Johnathan Priest, a law enforcement analyst.
