Michael Dunn, the Central Florida man accused of shooting and killing a teenager during an argument over loud music at a Jacksonville gas station in 2012, will face a second murder trial after an original jury deadlocked on the charge earlier this year.

A judge in Jacksonville ruled Monday that Dunn will be tried again starting Sept. 22, 2014.

In February, a jury deadlocked on the first-degree murder count, but convicted Dunn of three counts of attempted murder for shooting at his companions.

Jordan Davis, a 17-year-old from Georgia, was killed during the encounter at a Jacksonville gas station. Witnesses say Dunn complained that Davis and his friends' music was too loud, sparking an argument.

Dunn claimed self-defense, sparking another nationwide debate on Florida's "Stand Your Ground" law not long after George Zimmerman was acquitted of murder for shooting Trayvon Martin in Sanford.

Judge Russell Healey said Monday that Dunn won't be sentenced on the attempted murder counts until after his second trial. Healey says testimony gathered for the sentencing could taint the second trial.
