This is a special group. Hello I'm -- Hernandez in New York this ABC news digital special report final arguments are underway in the trial of Michael -- The 47 year old Floridian charged with killing seventeen year old Jordan Davis police say Davis was unarmed but Davis -- historian says. -- saw Davis with a shotgun or something that looked like it. Today the prosecution tried to show that davis' actions were premeditated. That -- TV's Jeff deal in Jacksonville Florida had been following the latest and has this report. Then better to thousands wow when did it and -- -- killed Jordan day event. There was no gotten. That's how state prosecutor Aaron Wilson started closing arguments in the Michael -- murder trial. Done from Brevard County is on trial for the murder of seventeen year old Jordan Davis at a Jacksonville gas station. Following a dispute over loud music. Not of them. Hitting that car. And then hitting and -- part. His heart attacks and they had no -- And -- Prosecutors have said all along done shot into the red SUV aiming to kill Davis because he felt disrespect it. Yesterday Dunn testified though in his own defense claiming he thought he saw a gun was threatened and felt his life was in danger and that's why he opened fire. But no gun was found in prosecutors have hammered on that point Kenya where -- they he knew he was an arm. -- -- And this morning Wolfson told jurors about done fleeing the scene saying he left because he knew what he'd done was wrong. She told jurors he's guilty of first degree murder. All right that was Jeff deal reporting so for now. Let's bring in Ryan Owens who was in the courtroom for more on the case Ryan that the court -- the prosecution very forceful. In their final arguments. How have they done so far in this case. Well they are -- I am -- to be remembered here trying to go for first degree murder conviction you're trying to prove that this man. Group holed up to a gas station got into a confrontation with a group of teens over loud rap music. She did not know. They have to prove that he premeditated. That -- -- to get a first degree murder conviction so you believe they're being forced. Looking -- -- we talked about Michael -- oversaw the package Michael done taking the stand. What terms of his actions and what he has said has had prosecutors been trying to use against him. His story out what actually happens -- when two cars were side by side. As changed. Like we. I'm over the over the years and of course any time the defendant is on the stand and why. Defense attorneys and when their quiet -- on the stand. Prosecutors will hammer hole any inconsistency. -- it. Didn't -- Jordan gave it. Actually get out of that -- are one -- on where -- they've got all these things. Slightly changed over the years and -- story and the prosecutor went after him about that as you heard. Problem about that reporter Jeff deal they are also making a tremendous -- Well Michael don's behavior. After it issued -- remembered -- reported this to anybody. And his fiancee went back to a hotel room they ordered -- they poured some ranks. They went to sleep they watched television and -- -- in the copiers laugh out of their hotel. And then drove -- who would after hours the next state without telling -- Even after they had seen on the news that a teenager died after being shot at the very gas station they were -- -- for. So I think for a lot of people especially the mothers on the jury his behavior -- behavior -- behavior after the shooting. May be just as troubling -- the crime itself. At one point we do know that he became emotional on the stand certainly the defense would like to present their client is someone. With with true and deep feelings and remorse let's listen to some of his testimony. If it wasn't just violence -- -- agreement on -- And -- that. In terms of her mental state he still feel pulling in terms of the threat of imminent danger you're right I mean it's now -- the book is not -- viewed. OK -- he talked about being afraid for his life as well as I presume the -- of his fiancee now she. Pulled into that convenience store parking lot with him that she was in the store at the time -- shots were fired. Looks a little bit about her testimony she isn't exactly. Stood by -- and at this juncture correct. As usual I I think you can make the argument that she really was the star witness for the prosecution urged the very reluctant. To tell you she was. Crying on -- stand actually sobbing uncontrollably. And shaking she was custom -- quite quite -- she didn't wanna eat there. A lot of her testimony was very damaging not the least of which was. She says she justified over and over again that one state pull out of -- after the shooting. That her fiance a lot of her life Michael -- never launch testified that I saw -- -- I had to do this because I saw it got a nice solid -- And remember this is going to be -- self defense case which is certainly what the defense's opening and Michael -- -- open the jury will you. You have to believe that he wouldn't -- is light. When those when he saw those -- teenage boy edit or two to believe that. You have to think that they katic on something. And -- them not to mention that she was driving away from the scene. Witnessed beyoncé and hurt the city that it contradicts and he says though I Eller didn't understand and I. All but her directly Conn contradict him on something like that I think was very. Was it possible to read the jury it all as those two witnesses testified the key witnesses Michael -- and his defense and his fiancee for the prosecution. Well to tell you paid closer -- detention yesterday during Michael -- Testimony and I was watching or sixteen jurors or altered and we don't know exactly which -- and that the -- twelve. But of course any -- the defendant takes the stand you know everybody sort of -- the court room and that's certainly want to keep. The jury when they walked out and all Michael and sitting in the -- even though I think most people -- -- -- to take. Yet it still sort of jarring to see that especially in a murder case. And tightened the jury are often very difficult to read and and what -- which tablet this. Important sort of -- -- -- that sort of like tennis match where it here looking at the prosecution then looking upbeat. Been looking at the defendant and important back and forth. And we saw them taking notes and we saw them paying close attention but I can tell you as. Michael doesn't -- on the -- for almost four hours -- -- several jurors. That it appeared stop listening to and I don't know if that's because they've made up their mind -- they just couldn't believe his story after. A certain amount timer what it will -- is very noticeable to a lot of -- the courtroom. Oh several of those jurors seemed to be tuning -- toward the end of his testimony. Also a couple of them sort of looking at him incredulous flee like. You know that you ordered pizza after you killed a young man. Did you not all 911 of course this is all speculation -- what they're thinking in their. Court papers that I -- that that I would be very nervous about. Interesting and what's next up for the case today Ryan. We already had the worst part of this State's closing arguments up next after lunch -- a lunch break right now we're just blunt talk did you. On the will come back and -- -- will have up to two hours to present. They're holding -- arguments. In the state which of course has the burden of proof that means they get to go out the last word they have thirty minutes -- They took an hour and a half this morning and so they do they're closing in -- injury instruction. Which I should point outside and -- -- days. This will go on for a very long time to judge -- reading -- more than an hour to the port jurors -- have to sort through this. Because struck all sorts of thing all kind of option. From an acquittal to manslaughter or second degree murder first degree murder and other things that are wrapped in Florida and the standard -- -- very complicated bill. We do think the jury will get the case will. Today. Most experts think -- habit for a while simply because just going through those with the jury instructions and the charges. Big enough to make anybody's brain hurt so imagine it would simply be able to come back quickly it will seek -- just social and -- late tonight but -- Write him very serious and complicated. Job had him ABC's rhino and outside the courtroom in Jacksonville Florida thank you so much for joining us. And we heard Ryan mentioned the stand your ground law which is something that has come into play in this trials -- we want -- Get into the legal lingo in the nitty gritty of this case and bring and homicide prosecutor and a -- -- Nicholas -- And if they get the fact that Dunn did not call the police that night we heard Ryan talk about that he said. He didn't realize he'd heard anybody. How does that play in terms of the prosecution. You know they talk about all kinds of details in this case but that given that he's saying this was her stand your ground and in self defense will that hurt him. It's doesn't -- in his fever while there is no requirement for someone to notify authorities again they have to be the jury. They must believe Michael -- For them to you ultimately quit -- comeback with a lesser charge most likely here. So again where someone has talked about being in such fear that he had to not only use a weapon but continuing to fire and then flee. The scene after using that weapon the fact that he did then not seek out the police to say hey I was a one under attack here it's not certainly not going to play newspaper here. -- we talk a lot about the stand your ground -- it is certainly controversial. In Florida and outside of Florida as well. What what do you have to prove in order to to show that you were that it pertains to you in other words. And it does Dunn's attorney need to show that he believed they were armed does the attorney need to show that they were in fact armed which they were not. Or -- easy -- to show that that done within. Danger of being hurt. He doesn't need to show that he was -- basically the difference with the stand your ground law and other. Legal justification is that under -- underground laws the person under attack who believes -- -- under attack does not need to retreat. What the defense ultimately needs this jury to believe is that -- both himself feared that he was either about to be killed -- very seriously injured. Not only that he believed -- but that anyone looking from the outside a reasonable person also believed that. And that's where you start to get although it sounds very tricky -- common sense and that's -- I think the defense isn't real trouble here. First of all there's no evidence that these young men -- teenagers had any weapons and based on the fact that he's been caught up in his lies will injury even believe that he believed that -- that he was just someone. That felt challenged. And boiled over and then used his gun which ultimately killed a seventeen year old here and -- and I should point out. I -- I didn't mean to imply that they are using to stand your ground defense formally in this case it is something that exists. In the courtroom but certainly they are saying that this is not premeditated stand your ground has not officially coming to play in this case. Let's talk a little bit about the fiancee would she mentioned she. Is not corroborating his story she said that never told her he thought he saw a gun in that car she was apparently emotional on the stand. And are really played in the the prosecution's case how much does that hurt done. I think it hurts him. A lot here is a woman who clearly did not want to be there what that means to the -- it goes to her credibility it makes her more believable -- certainly is no one on the stand with any ax to grind with her fiance. It is someone who gave her statement to the police initially when they questioned her and is now on the stand under -- being asked those same questions so her tearful -- I believe when I look at and I think the jury will as well it goes to her truth and she knows what she is saying hurts him. But yet it is the truth and she's going to stick with it because she understands her -- and the big thing here for her. Is that she testified just as she told police that Don never mentioned weapons to her when they left that gas station. And if he did not believe there are weapons if you didn't see weapons or at least believed that they -- there why on earth did he take that gun and use -- the way that he did. Somebody else prosecutors played -- was the video of the police interrogation of done after the shooting let's listen to -- -- -- This is -- These things through law OK you have -- use the bathroom hammered out here hope that you know check ammonia future. Actual work for that she's perfect -- Yeah. -- -- I'll be right back -- -- Europe. Will. All right and as they get this is someone who left the scene without calling police -- didn't think anyone was hurt. -- -- -- checked into the hotel room had a couple of drinks and then we see him when he's finally caught up with police. Very calm very relaxed how might that play to a jury. It is someone who is com and thinking it is not anyone who is so distraught over now what he has done -- again while his claim is that he certainly didn't know that he shot let -- killed anyone he did learn that. Throughout the night to by the time he is in that precinct he knows that he is responsible for the death of a seventeen year old. And one would expect whether it's -- are reasonable person. They would certainly be distraught and upset by their own conduct whether they were justified or not. So I believe how it plays in as the prosecutor certainly telling the jury is the jury did hear today that is someone who. Made those actions consciously. He did not like being challenged he fired that gun without thinking of the consequences and now is while he's calculating thinking about what to say the police that can help -- after he sees the results of what he did. And and a thing of the defense made the unusual call to put him on the stand it you know we we almost never -- that was this. A good decision. -- -- usual almost necessary and while of course the defendant never has any burden to give any evidence the jury without him taking the stand the jury had nothing. With which to -- and consider self defense. Again that prosecution chose not to put on his statements initially in their case which is their right they can prove this case to the jury by any means. So the only way the jury would hear why it is that the defense. Could prove hopefully to the defendant. That he was justified that he was in fear for his life when he fired their shots without the statements to the police is that Michael -- needed to take the stand which is what happened here. All right homicide prosecutor and a -- and -- a -- -- thank you so much for joining us. He can get a complete recap right here on abcnews.com.
