JACKSONVILLE, Fla. (AP) A man accused of killing a teenager during an argument over loud music appeared in court briefly for a hearing in Florida. <br />
<br />
State attorney's office spokeswoman Jackie Barnard says Circuit Judge Russell Healey on Monday made no rulings, setting a new hearing for Sept. 8. Jury selection begins Sept. 22 in Jacksonville. <br />
<br />
Jurors deadlocked in February on whether Michael Dunn was guilty of killing 17-year-old Jordan Davis of Marietta, Georgia. He was convicted on three counts of attempted murder for shooting at three others in the car with Davis in November 2012. <br />
<br />
Witnesses said Dunn complained that the music coming from the teens' vehicle was too loud, sparking an argument. Dunn claimed self-defense and said he fired into the vehicle because he feared Davis had a weapon. <br />
