Jonathan Bun, who was 17 at the time of the slaying, was given the maximum sentence possible with an additional 70 years for the killing of the 55-year-old Daly, after a traffic stop on July 20, 2011. Daly had more than 25 years of law enforcement experience with the Clayton County police and sheriff’s departments.
The Atlanta Journal-Constitution reported that Clayton County District Attorney Tracy Graham Lawson said if the capital punishment was not banned for offenders under 18, they would have sought it.
"If the U.S. Supreme Court had not said we can't seek the death penalty, we would've sought the death penalty," said Lawson, who had presided over some of Bun's criminal cases as a juvenile judge and recused herself from any dealings with the murder case.
Lawson outlined a pattern of criminal behavior dating back to when Bun was 10 years old.
"I probably saw over 17,000 juveniles," she said. "This one was unusual. From the time he was 10, his family was afraid of him."
Superior Court Judge Deborah Benefield said Bun appeared to not show "any remorse" when she gave out his sentence. As Bun approached the judge with his attorney Lloyd Matthews, he apologized to Daly's family.
Cheryl Daly, the wife of the deputy, wished no mercy on Bun following her daughter, who also beseeched the court to apply the stiffest penalty.
"I believe he should get life without parole because he took my husband's life," Cheryl Daly said. "He should pay with his own."
A recent decision by the U.S. Supreme Court prohibited mandatory life-without-parole sentencing for murder convicts younger than 18.
In May, a jury found Bun guilty of murder. He testified during his trial that he had no idea that a deputy was walking up to his friend's car, so he opened fire.
