JACKSONVILLE, Fla.-- Michael Dunn testified in his murder trial Tuesday.
Dunn was emotional at times, but calm. For the first time, Dunn broke down that night second by second.
"The body panels were shaking. It was ridiculously loud music," said Dunn. "I said 'Can you turn that down please?" said Dunn.
He testified the teens then turned the music off.
"I said thank you," said Dunn.
But Dunn said then the music started again and so did the exchange of words. Dunn said he had no choice, but to fire his gun. "I thought I was going to be killed," said Dunn.
The prosecution also accused Dunn of changing his story. Dunn told the prosecutor, "You weren't there" to several of his questions. Dunn talked about leaving the scene, ordering a pizza with his fiancee and trying to explain to her what happened. He said she was hysterical.
"I didn't do anything wrong," said Dunn.
Dunn maintained Davis escalated this fight and Dunn never meant to kill anyone.
"Did he threaten you like a child?" asked Dunn's attorney Cory Strolla.
"No, he threatened me like a man," said Dunn.
The closing arguments will continue Wednesday. The jury could start deliberating Wednesday night.
