Jonathan Bun: Deputy's accused killer takes the stand

A man who admits killing a Clayton County deputy took the witness stand on Thursday and denied knowing he had shot an officer.

Jonathan Bun took the stand and immediately started to describe the events of the night. Bun is accused of killing Deputy Rick Daly, a 25-year police veteran. Bun was arrested hours later after a massive manhunt. 

Bun said he was in the passenger seat of his friend’s car and noticed a white truck following him. Inside the white truck was fugitive-apprehension team trying to arrest Bun on armed robbery charges, police said.

Bun said he saw Daly approach, but he had no idea that it was a deputy walking up to his friend’s car, so he opened fire.

"After I shot, I feel like the bullet struck the person. [In] a quick split-second, I looked at the person that was on the floor, which was Deputy Daly, and after that, within a split-second, I just took off running," Bun said.

Prosecutors pointed out that during a videotaped interview, Bun told investigators he saw blue lights in his side mirror and knew it was an officer.

Bun also testified he had never heard of an undercover officer. The remark led to some snickering in the courtroom, Channel 2’s GA Daily News reported.

"As far as I see, I’m not guilty of malice murder because I didn't just wanna kill a person in cold blood, Bun testified. ”I could even say I’m guilty, but I’m not wrong for what I’ve done.

Closing arguments are expected in the case on Friday moing.
