Michael Dunn was found guilty Wednesday of first-degree murder for killing 17-year-old Jordan Davis on Nov. 23, 2012, in a dispute over loud music outside a Gate gas station.
Dunn, 47, faces life in prison without parole when he's sentenced. A sentencing date has not yet been set.
Dunn showed no emotion when the verdict was read.
The jury that heard Dunn's first trial in February found him guilty of three counts of attempted murder and firing into an occupied vehicle related to the three other teens in the SUV, but a mistrial was declared on the first-degree murder charge when the jury remained deadlocked after 30 hours of deliberations.
