The ruling of a Florida jury against a man for the murder of an African American teenager in 2012 has once more placed racial issues in the spotlight in Florida.

A Jacksonville jury found Michael Dunn guilty of attempted murder in the second degree for shooting against three African American teenagers in a car on November, 2012; however, a charge for the murder of teenager Jordan Davis was nullified after a jury did not manage an unanimous verdict, said the CNN in its coverage of the trial.

After 30 hours of deliberations, a jury comprised of 13 people did not reach an unanimous verdict, and the prosecutor must decide if Michael Dunn will be processed again for the charge of first degree murder; Dunn is a gun collector and programmer that in November of 2012 shot 23 times against Jordan Davis because he refused to lower the volume of the music in his car.

According to ABC, the night of November 23, 2012, Davis was sitting in the back of a truck listening to loud music with his friends, Leland Bruson and Tevin Thompson, waiting for a fourth teenager that had gone into a gas station to buy cigarettes.

Michael Dunn parked next to their car and asked the teenagers to lower the volume of their music, a request the teenagers refused and started an argument that ended when Dunn drew his weapon and shot the truck, killing Davis.

According to a report by the quoted source, 47-year-old Dunn told th jury that he acted in self-defense after being threatened with a shotgun which was never found, since Davis and two minors with him inside the car were a "clear and imminent danger".

Russel Healey, the Judge in charge of the case announced on Sunday that the court would reconvene on March to determine the date for Dunn's sentence, who might face up to 75 years in jail.

However, the preliminary result which nullifies the first degree murder charges for the death of the teenager, who was 17-years-old, has unleashed a series of negative reactions against what many consider to be a racial crime.

Prosecutor Angela Corey told CNN that the teenager's parents, Ron Davis and Lucia McBath are seeking a new trial over the murder charge.
