Michael Dunn appeared in court Monday morning for a pretrial hearing, and the judge set one more hearing before his trial next month.
Dunn is charged with murder in the shooting death of 17-year-old Jordan Davis during a dispute over loud music at a Southside gas station in November 2012.
Dunn's next pretrial will be Sept. 8. Attorneys in the case will file all their motions on Sept. 2. Jury selection begins Sept. 22.
Among the witness list filed by Dunn's lawyer is Levar Floyd, who's serving an eight-year prison sentence out of Duval County for battery and assaulting a police officer. Jail records indicate Floyd was in jail for several months before and after Dunn's first trial. It's uncertain what Dunn's lawyers intend to ask him.
Jurors deadlocked in February on whether Dunn was guilty of killing Davis. He was convicted on three counts of attempted murder for shooting at three others in the SUV with Davis.
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.
