Teen Jonathan Bun faces sentencing in killing of Clayton Co. deputy Rick Daly

Sentencing is scheduled for a teenager on Thursday who shot and killed a Clayton County deputy. Jonathan Bun faces life plus 70 years, but his sentence could be impacted by a recent Supreme Court ruling outlawing life without parole sentences for underage offenders.

In July of last year, Bun shot and killed Clayton County Deputy Rick Daly. The deputy was trying to help arrest Bun, who was wanted for robbery.

Bun was 17 at the time of the killing, but 18 when the guilty verdict was read in court. Originally the state wanted to seek the death penalty, but couldn't because Bun was too young.

Prosecutors are now pushing for the maximum sentence, life plus 70 years. The defense is expected to fight to reduce the punishment handed out by the judge.

Bun's sentencing had been delayed, due in part to the Supreme Court's ruling. The judge wanted to make sure the Supreme Court's ruling came down before he imposed the sentence on Bun.
