Defense rests in Florida loud-music killing trial

JACKSONVILLE, Fla. — The Florida man charged with fatally shooting a 17-year-old boy after an argument over loud music testified Tuesday that he thought he saw the barrel of a gun from a neighboring vehicle pointed at him and that he feared for his life before firing his weapon.

Michael Dunn said he tried to calm down the confrontation with three teens in a neighboring SUV outside a Jacksonville convenience store in November 2012.

‘‘I couldn’t believe what I was seeing and hearing,’’ the 47-year-old said.

Dunn is charged with first-degree murder. He has pleaded not guilty and says he acted in self-defense when he fatally shot 17-year-old Jordan Davis of Marietta, Ga.

The defense rested its case Tuesday, and then prosecutors called Dunn’s fiancee back to the witness stand. Rhonda Rouer contradicted Dunn’s assertion that he had told her he had seen a gun in the teens’ SUV. Closing arguments were expected Wednesday.

Prosecutors also played a video of Dunn’s jailhouse interview in which he could not explain why he did not call police after the shooting. Also in it, detectives picked apart Dunn’s story that he was threatened with a gun, saying no weapon was found on the teen and witnesses never described Davis making threats.
