JACKSONVILLE, Fla. (AP) - Prosecutors are presenting their opening statements in the trial of a Florida man charged with fatally shooting a 17-year-old teen during an argument over loud music at a Jacksonville gas station.
    
Michael Dunn's trial is getting under way Thursday, a day after a panel of 12 jurors and four alternates was picked.
    
Authorities say 47-year-old Michael Dunn fatally shot Jordan Davis of Marietta, Ga., outside a convenience store in Jacksonville in November 2012. Dunn has claimed he felt threatened and thought Davis had a gun.
    
Dunn and Davis had begun arguing after Dunn complained that music coming from a vehicle with Davis and two friends was too loud.
    
The trial is expected to last more than a week.
