TULSA, Oklahoma - Candlelight filled a downtown street as people mourned the loss of a young man, shot and killed by an off-duty officer last week.

Rodney Walker's mother, Lakonnia Davis, said she does not believe her son one would have pulled a gun on anyone; but that's exactly what the off-duty officer said happened.

Walker made an impression on all of the people in life, and is causing them to come together after his death.

"Rodney told me, ‘Man just pray about it. Pray about it.' So does that sound like somebody that's very violent to you? I don't think it does," said Walker's cousin, Lajessica Mayo.

Loved ones at a vigil Friday night took turns sharing how the 23-year-old touched their lives.

"I want everybody to know that Rodney was a great person," said Walker's grandmother, LouElla Aaron.

Davis summarized the group's feelings, saying, “We need justice. We will get justice and God will bring justice to it."

Walker was shot and killed a week ago, before the Garth Brooks concert last Friday.

Tulsa police said Walker was at 11th and Denver, lying on top of his girlfriend, Quinteisha Rice, punching her, when off-duty Department of Veterans Affairs Officer Andrew Bryiant stopped to help.

Police said Walker had a gun in his waistband and pulled the gun on the officer. That's when, police said, Bryiant opened fire.

"For them to say Rodney was a woman beater, I don't believe that. I don't believe that at all," said Walker's friend, Steve Agbonze.

Detectives interviewed several witnesses. The district attorney has not decided whether to file charges against the officer.

"I really feel strongly that he was doing exactly what he was taught to do and that's to walk away," Davis said.

She said she's talked to detectives, and wants more information about what provoked the officer to shoot her son.

Rice said Walker did have a gun, but did not pull it on the officer.

“We're not seeking death penalty or anything like that, we just want justice because it has to stop," said Reecee Buggswallace, Walker's aunt.

The investigation is complete and the district attorney must now decide whether to file charges.
