But the bottom line for the defense was that the murder scenario itself was absurd. We're gonna drive back to Atlanta to our condo in Buckhead, and on the way, I'm gonna shoot my wife through the back of the seat with her best friend sitting there. What? Are you kidding me? Come on. Finally, the defense offered a medical reason why Tex might have fired the gun when he didn't mean to. For years, Tex had been treated for a sleep disorder which caused him to jerk in his sleep. It's called confusional arousal. The defense called the sleep specialist who'd been treating techs for a decade. He did have a previous study that was done at Mayo Clinic Jacksonville in 2004, which did specifically comment about his moving his arms and legs in a sort of large amplitude movements while he was dreaming in the sleep lab. Confusional described a lot of things in this case. But if jurors were hoping closing arguments would offer some clarity, they were about to find muddy water. Coming up. When he killed Diane McGarvey, you know, it's like hitting the lottery. We are going to vilify Tex McGarvey. We are going to muddy him up. That's their mission. Accident or murder. A defendant under the gun and a jury all over it. We got to hold the gun, the gun and feel the force. What would the verdict be? When DATELINE continues. Prosecutor Clint Rucker faced the jury for the final time with a Mason jar of mud. I'm gonna make you a promise. By the time I get through with my argument and take my seat, this jar is gonna be clear. And it's gonna be clear. Just like each and every one of your minds will be clear about the guilt of this defendant. He drove home the prosecution's main argument one last time. When he killed Dan McGove, you know, it's like hitting the lottery. And that accidental shooting, you intended to do it. Man like you, gun expert, having financial problems, arguing about this ranch. Listen, Black Lives Matter is not about race. It's about the justification for having the gun in the back seat at the end of his closing. Despite his promise, the DA's jar of mud was far from clear. Not a good sign. That muddy water, said defense attorney Don Samuel, symbolized the state's murky theory. We are going to vilify Tex McGuire. We are going to muddy him up. That's their mission. Co counsel Bruce Harvey said the state's own evidence proved there was no financial motive to kill Diane. Tex was not broke, nor. Nor was he in dire financial straits. The state's calculation put Texas net worth at 1.7 million before Diane died. After 21 days of trial, the jury took over the fate of Tex McIver. And after three days of deliberation, it became clear that not many jurors were convinced by the prosecution's case, especially when it came to motive. Jury foreman Avi Robbins told us it all boiled down to one thing. The gun. We got to hold the gun. The gun and feel the force cocked, not cocked. I did the same thing with a similar gun and the help of firearms expert Jay Jarvis. Okay, so hardest thing is maybe cocking the gun. That requires a lot of effort. Yes. Once it's cocked, firing it somewhat easy. Very easy. Firing it uncocked requires more effort. Yeah, about six times the effort. So the obvious question, was Texas gun cocked or not? We felt that if it was cocked, then, yeah, it could have fairly easily been done on accident. The jury again asked to see the video from Texas police interview. Steve Maple, Texas attorney, answered their question. He didn't play with the hammer. He didn't pull it back at full. So the only evidence they could find that the gun was not cocked came from Texas own attorney. But even that didn't do it. After five days of deliberation, jurors sent a message to the judge. We don't see a path to overcome our differences on the defendant's intent. The judge refused to accept a deadlock and sent them back to deliberate. Four hours later, the jury signaled a verdict had been reached. Texas sister Dixie and his friends sat anxiously on one side. Diane's colleagues, including Jay Grover, filled the prosecution side of the room. The case that had riveted Atlanta was coming to an end. On count one, murder, we find the defendant not guilty. Not guilty of deliberately murdering Diane. But wait. On the felony charge of shooting the gun at Diane, you find the defendant guilty. Killing someone while committing a felony. Guilty of felony murder. Possession of a firearm in the course of a felony. Trying to influence the witness, Danny Jo Carter. Guilty. In lay terms, the verdict meant text is mean to kill Diane, but he did mean to shoot her. So when you hear the first guilty count, it was like, we got him, we got him. Texas lawyers were mystified. I think it's a mistaken verdict, and it is the result of a compromise, and I think it is just plain wrong. Texas sister Dixie is still stunned to
