Police believe a Marietta teen was killed at a Florida gas station for playing loud music.

Jordan Davis, 17, was gunned down at a Jacksonville gas station Friday night. A family friend told Channel 2’s Craig Lucie the teen would split time between his mother’s home in Marietta and Jacksonville with his father.

Jacksonville police said Davis was with his friends when Michael Dunn, 45, pulled up near their car. Police said Dunn got into an argument with the group about the loud music they were playing. Then, Dunn fired eight to nine shots into the car, fatally wounding Davis, police said.

Dunn's attorney, Robin Lemonidis, said one of the teens pulled a gun on shotgun Dunn, and he retrieved his weapon from his glove compartment before opening fire. Lemonidis said that evidence will show Dunn acted responsibly.

The Jacksonville Sheriff's Office said no guns or drugs were found in the teens' SUV.

“It was shock. I actually did a double take, because I couldn't believe it and as some details have come out, it was something that certainly shouldn't have happened,” family friend Larry Peck told Lucie.

Homicide investigators said Dunn fled the scene with his girlfriend, but he later said he felt threatened during their argument. His lawyer said he acted in self-defense.  Dunn pleaded not guilty to murder charges Monday.

Peck said Davis’ parents rushed to Jacksonville when they heard about the shooting.

“Hopefully, in time, they'll have an understanding of why everything happened the way it did,” Peck said.

The family plans to hold services in Cobb County for Davis on Friday.
