Dunn said aloud to himself, "You're not going to kill me, you son of a bitch," as he opened the glove compartment, grabbed his pistol, dropped the holster at his feet, chambered a round and began firing, he said.
Nine of the 10 rounds hit the car, three of them striking Davis, one of them cutting through his liver, his lung and his aorta.
Though the incident may have occurred quickly, "there's no certain amount of time that's required" for a defendant to form an intent to kill, Wolfson said.
She rejected Dunn's assertion that he had been trying to de-escalate the situation. "Every action he took was a conscious decision that he made to escalate the situation and ultimately kill Jordan Davis," she said.
She also rejected his assertion that he feared for his life.
"He had steady hands when he was shooting at Jordan's door," she said, referring to a picture that showed the SUV passenger door struck by bullets that had hit close together.
Defense lawyer Cory Strolla noted that no witnesses had accused Dunn of using any words of hate and testified that his client had just come from a wedding, where his ex-wife said he had appeared to be in a good mood.
Strolla noted that the SUV departed the gas station after the shooting and was gone for three minutes before it returned, enough time for the youths to have dumped a gun.
Detectives did not search the area for days after the shooting, he said.
Strolla cited testimony from another passenger in the car with Davis who acknowledged that he may not have heard all the conversation between the two men.
Though witnesses had testified that child locks on the SUV were engaged, and that Davis -- who was seated in the rear -- could not have gotten out of the back seat to threaten Dunn, Strolla said the teenager could simply have opened the door by putting his hand out the window, which was open.
"You have lack of evidence, conflicts of evidence and reasonable doubt," he told the jurors.
On rebuttal, Assistant State Attorney John Guy appealed to the jurors' "common sense."
"That defendant didn't shoot into a car full of kids to save his life," he said. "He shot into it to preserve his pride. Period. That's why we're here."
Though Davis may have had a big mouth, he had no weapon, Guy said. Though he acknowledged minor inconsistencies in witness accounts, he said that was to be expected. "It's not like television," he said. "In real life, there are inconsistencies."
If Dunn is found guilty, he faces up to life in prison.
