When asked why he didn't call 911 from the store after the SUV pulled away or from the safety of the hotel, where they spent the night, Dunn said he did call police once he got back to Brevard County.
"Whether I called police that night or the next morning didn't seem, you know, it wasn't going to change it from self-defense to anything else," Dunn told the prosecutor.
During cross-examination, Guy challenged Dunn's assertion that he had told his fiancée after the shooting that he thought one of the teens had a gun.
"You never told the love of your life that those guys had a gun," Guy said. "Did you?"
Guy also questioned why Dunn didn't call Jacksonville police right after the incident.
Dunn told jurors his plan was to call police when he returned home to Brevard County with his fiancée and dog Charlie.
"You killed a 17-year-old boy," Guy said. "And it didn't matter to you? You we're concerned about Charlie?"
Dunn replied to Guy, "I was concerned about Rhonda."
Later in the day, the prosecution recalled Rhonda Rouer to ask her when Dunn first mentioned that he saw a gun in the SUV. She said it was the next day, after Dunn took a phone call from a friend.
During nearly three hours on the stand, Dunn never strayed from his claim of self-defense. During a short redirect near the end of the day, Strolla asked, "Were you shooting only to defend yourself?"
Dunn's reply: "Yes, I was."
After the state recalled a homicide detective and played a portion of the video of Dunn's interview at the Brevard County Sheriff's Office the day after the shooting, the prosecution ended its case.
Attorneys who have been analyzing this case say Dunn's testimony was well-prepared and compelling.
"I would probably rate him (Dunn) about a six out of ten," said attorney Rhonda Peoples-Waters.
She continued, "He definitely laid the foundation of what's necessary for self-defense, and all he had to do is establish that his own perception is that some great bodily harm or death was about to come upon and that it was reasonable. It need not be actual."
As for attorneys handling the case, State Prosecutor Angela Corey started and finished strong with the help of two state attorneys.
Attorney Randy Reep says Defense Attorney Corey Strolla's performance was the biggest surprise.
"The wild card was Strolla who also did a fantastic job, and I don't think that was expected," said Reep. "I think he kept Dunn in the game with his good cross-examination early on, and I think he gave Dunn a good platform early on.
About 4:40 p.m., Judge Russell Healey told the jury that closing arguments would begin at 10 a.m. Wednesday, then dismissed the jury for the night.
Healey and attorneys for both sides remained in the courtroom to discuss pending motions and to discuss the language that would be used in jury instructions, including possible lesser charges and Florida's justifiable homicide statutes.
