JACKSONVILLE, Fla. -

New documents and audio released Tuesday by the state attorney's office provide more insight into what happened the night investigators say Michael Dunn shot and killed Jordan Davis in a dispute over loud music.

Dunn is charged with murder in the shooting death of the 17-year-old outside a Gate gas station on the Southside in November.

Witness statements from those who were in the SUV in which Davis was killed and from Dunn's girlfriend, who was in the store and talked to Dunn as they were driving off, are included in the nearly 150 pages of documents.

Jordan Davis Davis (pictured, right) and his friends were in a red SUV parked at the Gate station when Dunn and his girlfriend pulled into the parking lot and parked beside them, according to the documents. Dunn's girlfriend went into the store to buy wine, according to the documents. Dunn asked the teens to turn the music down, and he made a comment to his girlfriend about how he hated "thug music," according to the documents.

Dunn's girlfriend said that type of comment was common for him, but she said it was totally out of character to confront someone over loud music, according to the documents.

According to the documents, one of the teens in the SUV turned the music down, but Davis told him to turn it back up. Davis was cursing at Dunn and said, "I am tied of people telling me what to do," according to the documents.

One witness heard Dunn say, "You talking to me?" according to the documents, He said Dunn then got his gun from the glove compartment, loaded it and started shooting while sitting in his car, according to the documents. He opened the door, got out, crouched down and kept firing, according to the documents.

Dunn's girlfriend heard the gunfire in the store, went out and yelled, "Michael, what have you done?" according to the evidence materials.

Inside the store, those at the cash register also heard the gunfire.

"Somebody is shooting. Somebody is shooting out of their car. I swear to God. He is shooting. Right here in front of us," one witness said in surveillance audio from the cashier counter.

"The cops are right across the street," another said.

Dunn's girlfriend got in the passenger side of the car, and Dunn drove off to the hotel where they were staying, according to the documents. Witnesses who were in the store got the license plate number for Dunn's car.

Later on, according to the documents, when questioned by police, the girlfriend said during that conversation minutes after the shooting that Dunn never mentioned he thought someone in the SUV had a gun, just that he thought they were getting out of the SUV. He told her he was scared because people were making threats, according to the documents.

The teens in the SUV told police Davis had nothing in his hands.

When police questioned Dunn on the phone at his home in Brevard County before he turned himself in, they said he told them he knew what they were calling about. "I acted in self-defense. The guys were getting out of the truck," Dunn said, according to the documents.

When told he need to go to the nearest Brevard County Sheriff's Office, Dunn said, "This sucks."

Dunn, 46, was denied bond last week and will remain in jail until his trial.

Davis family attorney, John Phillips, spoke out Tuesday about the latest documents released about the night Davis was killed by Michael Dunn.
