Michael Dunn was found guilty of first-degree murder in the killing of 17-year-old Jordan Davis in September, 2012 after an argument over loud music.
The jury took about 5 hours to reach a verdict on Wednesday.
A jury deadlocked in February over whether to convict him of killing Davis.
He was convicted on three counts of attempted murder for shooting at Davis' friends in the car.
Dunn testified at this month's trial as well as his last that he killed Davis in self-defense after the teen threatened him. He also said he thought Davis had a gun, but no weapon was ever found.
