Dunn was previously found guilty of three counts of attempted murder in a February trial for shooting at an SUV carrying Davis and three of his friends.
During that trial, the jurors deadlocked on the decision to convict Dunn of first-degree murder.
Tuesday saw Dunn testify in his own defense. The jury began deliberations early Wednesday morning.
From The Florida Times Union:
Dunn, 47, testified that Davis was angrily getting out of a Dodge Durango while holding a shotgun and threatening to kill him when he pulled out his own handgun and opened fire on Davis and others in the vehicle.
“You’re not going to kill me, you [filtered word],” Dunn said he yelled at Davis seconds before firing ten bullets at the Dodge Durango Davis was in.
Dunn said he was scared for his life and would have been killed if he hadn’t pulled out his own gun.
“I shot to defend my own life,” Dunn said at one point while testifying on Tuesday.
During closing statements, Assistant State Attorney John Guy reiterated that no weapons were found on Davis or inside the SUV he and his friends were riding in.
