JACKSONVILLE, Fla. -

In interrogation videos of murder suspect Michael Dunn's interviews with police released Monday, Dunn gives his side of the story in the shooting death of 17-year-old Jordan Davis at a gas station that started as a dispute over loud music.

"Got out, she's in the store, and there's like an SUV next to us," Dunn told investigators. "And the music starts, and I roll down my window, and I thought I was polite. I asked them nicely. I asked, 'Would you mind turning that down?' They started. I was like, 'Thank you.' Cordial, everything's cordial. I put my window back up. I'm doing my stuff. I don't know how many kids are in that."

But Dunn said it didn't remain cordial. He said the music went back up, and then one of the teens started yelling, "Kill him." Dunn said he didn't know if they were singing to music or talking about him.

He said that one of the teens inside the SUV bent down to pick something up and he thought the teen might be reaching for a gun.

Defense lawyers for the teens say they were unarmed, but Dunn said he didn't know that. So Dunn said he reached for his gun and started shooting because he thought the teen was going to get out of the SUV. Dunn fired again as the SUV sped off through the parking lot.

"Quicker than a flash, I had a round chambered in it and I shot," Dunn said.

"Do you remember how many times you shot?" a detective asked.

"I shot four times and pull out, and in my mind they got a gun," Dunn said. "And so not training, I was still scared. And so I shot four more times."

"When you were fleeing?" the detective asked.

"Yeah, when their heads were down to not catch any return fire," Dunn said.

After the interview, detectives at the Brevard County Sheriff's Office told Dunn that he was going to be arrested and charged with murder and attempted murder.

Videos and audios of several witness interviews were also released.

The fiancee of a man who was using the restroom at the Gate gas station told detectives she heard gunfire and looked to see a middle-aged white man leaning out of a car with a silver handgun.

"I heard two loud bangs real quick, and then the car was speeding off," she said in a sworn statement to detectives. "And then there were another four or five after that, and he had the gun in his hand."

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 spoke with Dunn as they were driving off, are included in the nearly 150 pages of documents that were released last week.

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