>> i hear a big explosion. i just knew immediately that i had to get out of there. >> a single gunshot, and she was gone. >> the love of my wife. >> you said tex was emotional and distraught. >> yes. he's never been the same since. >> what happened in that dark suv? and what was hiding beneath the surface? >> trying to cover up something. >> i just took my breath away. >> she said, i cannot trust anyone else. >> power and privilege. love and greed. >> she was in control of the money. >> this had to be an intentional act. >> did a secret lead to murder? >> i just looked at him and i said, i can't lie. >> all that glitters is not actually gold. >> hello and welcome to "dateline. " diane mciver was an atlanta businesswoman who enjoyed an extravagant lifestyle with her husband, tex. then in a flash it was gone. a strange car ride through a dodgy neighborhood left one person dead and another struggling to explain how it happened. it was a mystery riddled with wealth, privilege, and power. but for investigators, it boiled down to one crucial question -- was this an accident or murder? here's josh mankiewicz with "deadly detour. " >> all they wanted was to get home. turning off the interstate. to escape the crawling atlanta traffic. >> he says, girls, this is the wrong place, we don't need to be here, this was a bad idea. >> it's still hard to math tom fathom what happened next or why. >> i was trying to figure out where the explosion was. >> but here's what's pretty clear. one wrong turn really can destroy your life. >> to think that one moment in time you have an accident and you lose everything after that. >> our story begins and ends with her, diane mciver. nobody knows her better than dani jo. >> she's beautiful, she's funny, she was brilliant. she was driven. >> diane was born in auburn, alabama, where she survived a sad and difficult childhood. she realized her dreams in atlanta, a place that matched her ambition. >> what was she looking for? >> she was looking for success. >> diane was barely out of high school when she went to work at u. s. enterprises, a company in atlanta. she was a bookkeeper, but soon caught the eye of her boss, billy corey. >> there were some people working there that weren't really doing their jobs, and she told him she could do their job and her job. i think he fired them and she did their job. >> it was back in the'80s when dani jo and diane first teamed up. best friends and confidants. dani jo was a cosmetologist with a front row seat to diane's brilliant career. >> she loved crunching numbers. and along with billy corey, i think she learned how to wheel and deal. >> she rose through the ranks. and with her boss'blessing became president of the company. hiring, firing, and calling the shots. >> she would say, i don't want to hear about the labor pains, just show me the baby. >> jay grover was a vice president at diane's company. >> when she started in business here in atlanta, there were not a ton of female executives. >> no. absolutely. and i think that's what -- one of the things that really set diane apart. i mean, she was a -- a woman in a man's world. >> she had a big personality, loved clothes, furs, hats, and kids. although she never had any of her own. she survived one bad marriage and was in her 50s when she met tex mciver. he was self-made too, a military brat from san antonio who earned a rep in atlanta as a labor lawyer and a champion of republican candidates. >> he had great relationships, he had everybody's direct-dial mobile number. >> bill crane is a political commentator and consultant in atlanta and a long-time friend of tex. >> he was a gentleman, he as gentleman. both in terms of old courtly manners, standing when a lady enters the room. >> tex was divorced too. that's how he ended up living in the same condo complex as diane. >> they started going out. she said she started talking to him, but he was too short and too old. but obviously she got over that. >> it didn't hurt that he had this ranch east of atlanta. it was nice enough back when tex first bought it, but it was fabulous after diane got through with it. it had a pool, gun range, ponds, horses, saloon, and texas longhorn cattle. that's diane. they were there a lot. >> diane was a great hostess. she was the life of the party. >> soon tex and diane decided to make it permanent and a wedding date was set. november 5th, 2005. at the ranch. everyone at the rehearsal could tell this wedding would be over the top. and it was. >> it looked like something out of a disney movie. >> sheriff howard sills was on the guest list. >> there were hundreds of people here. people -- all aspects of society here. >> they'd both been married before and decided this time to keep finances separate. nearly a year later, their lives were blessed with a little boy. sort of. a couple of friends asked tex and diane to be godparents to their baby named austin. diane's assistant, terry brown, says diane would do anything for that little boy. >> he was the sun for her. the moon and the sun, i guess. the stars. he was the whole thing. >> it's all about austin. >> that was never more obvious than at the birthday bashes she and tex threw for austin. an annual exercise in excess. >> we love you very much, don't we, darling. >> yes, forever. and ever. >> bye-bye! >> bye, i love you! >> three weeks after austin's 10th birthday, tex and diane, with their friend dani jo, were headed home after a weekend at the ranch. they were driving a king ranch ford expedition, virtually identical to this one, and they made a short stop for dinner. it was september 25th, 2016. the day everything changed. after dinner, they headed for home. a trip of about 45 minutes. tex and diane had had a little wine at dinner, so dani jo drove. diane sat next to dani jo in the front seat and tex was right behind diane in the back seat, and off they went. >> well, we headed on into atlanta on i-20. as we got off of 20 to get onto the connector, it was just eight lanes of brake lights. >> dani jo says tex was dozing in the back seat as the two women decided to get off the interstate to avoid the traffic. >> as we're riding down the ramp, tex becomes fully awake, i guess. he looks around and he says, girls, i really wish you hadn't done this, this is a bad idea, this is a bad area. >> that's when tex mciver made a request of his wife. will >> and tex said, darling work, you hand me my gun? >> tex regularly kept a gun in that car? >> uh-huh. >> it was right in the center console, a smith and wesson. 38 caliber revolver. >> and so she reaches down and gets it and hands it back to him. >> in a plastic bag? >> uh-huh. >> in minutes they were out of the sketchy area and moving up piedmont ave to the cushier parts of midtown. everything was normal. unremarkable. >> we were talking about politics and the debates. >> what is tex doing? >> he wasn't really talking. i kind of -- i thought that he had gone back to sleep. >> they were at piedmont and 14th street. >> we were just sitting there, still waiting for the light to turn. and i hear a big explosion. within seconds diane turned around toward the back and said, tex, what did you do? >> he say anything? >> he said the gun discharged. then she started moving. she started moving forward. and she kind of turned around. and she was moving funny. and she said, tex, you shot me. >> what happened in that suv? a stunned diane is rushed to the hospital. coming up -- >> tex was calling her name, and she was kind of breathing panicky. >> he said, there's been an accident. >> tex faces questions from police. >> handling the gun. i didn't realize it was in my lap. i'm going to cry. the love of my life. >> when "dateline" continues. dupixent i can du more... yardwork... teamwork... long walks.... that's how you du more, with dupixent, which helps prevent asthma attacks. dupixent is not for sudden breathing problems. it's an add-on-treatment for specific types of moderate-to-severe asthma that can improve lung function for better breathing in as little as two weeks. and can reduce, or even eliminate, oral steroids. and here's something important. dupixent can cause serious allergic reactions, including anaphylaxis. get help right away if you have rash, shortness of breath, chest pain, tingling or numbness in your limbs. tell your doctor if you have a parasitic infection, and don't change or stop your asthma treatments, including steroids, without talking to your doctor. are you ready to du more with less asthma?

>> yes. >> then they took her to headquarters for questioning. she told police what happened in the car. >> he woke up, and i guess he had it -- had it in his hand, and he just pulled the trigger. >> as she sat there, dani jo was still thinking diane was going to be okay, but then -- >> they had gotten a call, and they -- they both left the room. i was sitting alone, and then i get this text from my husband. >> no. no. >> that diane had died. >> it turned out the gunshot wound through diane's back was catastrophic. the blood loss, too great. >> and i was devastated. i couldn't believe it. >> diane mciver, so much larger than life in so many ways, was suddenly gone. >> tex called me in the early hours of the morning and he said, there's been an accident and we've lost diane. >> dixie martin, tex's sister. >> how long until you realized the accident involved something he had done? >> later in the conversation, and he was very emotional on the phone. i mean, we were both crying. >> what was it like to break that news to people at the office? >> it was -- it was heartbreaking. >> diane's company put her picture up on their landmark tower in atlanta. all the while, police were trying to figure out what exactly had happened in that car that night. three days after the shooting, tex and his attorney steve maples went to answer their questions. maples offered a preview. >> his only recollection is he had the -- the brown paper bag -- i mean, plastic bag and he's holding it down like this. and he said, he didn't play with the hammer and he didn't pull it >> this is tex's attorney saying the gun wasn't cocked. you'll want to remember that part. tex himself entered shortly after and went over the whole story, explaining why he was so scared on that drive he felt he needed his gun. >> we went through an area i thought that was particularly dangerous at night. i had seen police vehicles there. it's -- it's a route i take from my office to her office. that's one that has a particularly high population of homeless people. >> okay. >> and -- and i quickly said, this is a big mistake and we're in a place that we don't belong in. >> that, tex said, is when he asked for the gun. a few minutes later the threat seemed to pass and tex said he fell back asleep. >> anyway, i just -- just time to wake up and -- but she came to a stop, and i was handling the gun. did not realize it was in my lap. >> right. >> and it went off. >> he seemed emotional as he recalled how doctors told him his wife was dead. >> two surgeons in scrubs and a chaplain come around the corner and start walking towards me. i actually looked behind me, hoping it was somebody else. i'm sorry. >> no, take your time. >> the love of my life. >> if tex mciver had done nothing after that, if he had kept his mouth shut, if he had just grieved, we probably wouldn't be telling you this story. but doing nothing? that's just not tex mciver. coming up -- a media firestorm, and tex provides the match. >> tex's comment -- >> gets blown up into, he's making this up to get out of the fact that he shot his wife. >> could this have been more than an accident. >> there were no tears, there was no -- i never saw him cry. >> when "dateline" continues. ♪ there are beautiful ideas that remain in the dark. but with our new multi-cloud experience, you have the flexibility you need to unveil them to the world. ♪ tv: mount everest, the tallest mountain on the face of the earth. keep dreaming.

" it didn't exactly work as planned. >> tex's comment that he didn't know whether the people around the car were homeless people or some kind of street criminal or a black lives protest -- >> gets blown up into "bonfire of the vanities, " larger than life and he is making it up to get out of the fact he shot his wife. >> and it morphed into black lives matter. >> that's correct, which he never said and i never said that he said. >> the story with its racial overtones went viral. while tex was fighting to repair his public image, diane's colleagues were questioning things after her death. >> there were no tears. i never saw him cry. >> ken rickert is the company's general counsellor. >> i never heard him say it was an accident, i'm so sorry. >> tex look crushed, sad? >> i didn't detect any of that. he was -- he was just kind of matter of fact. >> diane's colleagues also thought tex seemed way too interested in how his financial situation would change now that diane was dead. >> and he asked a very strange question about did i know anything about social security, could he get any of diane's benefits. and i was shocked. >> tex's sister dixie says she was flabbergasted that anyone thought tex wasn't behaving appropriately. she says he was clearly devastated by diane's death. >> he cried all the time. i don't know why no one else has seen this. tears running down his face. he has never been the same since. imagine losing your loved one at your own hand, and that's what he had to face. >> in perhaps another effort to counteract the rumors and innuendo, tex decided on his own to take a lie detector test, administered by an examiner his attorneys hired. >> i think it is important to note that he passed with flying colors. >> diane, love you and we're going to miss you. >> but a month after her death tex walked into the lion's deny at the company memorial service for diane. dixie attended with tex and it was an evening she came to regret. >> we walked in through a little gang plank-looking thing, and to the left is her jaguar with a light on it and a red rose on the hood. and i'm thinking, okay. >> they pass diane's car and entered a large room. >> and there's a mannequin with diane's clothes on it. >> with godson austin at his side, did tex even notice the under current in the room?

it was a question that would haunt diane's friends and leave investigators to a potential motive for murder. once again, here's josh mankiewicz with deadly detour. >> with police investigating, rumors flying and even old friends becoming suspicious, tex mciver seemed to be doubling down. about two-and-a-half months after diane was killed, tex put her furs, clothes and jewelry up for sale. even though his friend sheriff sills told him, bad idea. >> i said, tex, this doesn't -- that doesn't look good. i mean if you don't have to do this right now, don't do it. >> but he did. >> never met a mannequin she didn't like? >> that's right. [laughs] >> auction house owner robert ailers ran the sale and even he was impressed. >> how many pieces total. >> there were over 100 jewelry items, not costume, but real jewelry and one of the big lots were a pair of diamond studs that were several carats each. >> i heard people were lined up three and four deep to try on the jewelry. >> before the sale started there were probably 150 to 200 people in line to get into the building. >> so the notoriety helped. >> the notoriety definitely affected the sale, yeah. >> did you tell him that unloading all of diane's stuff so soon after she died would be seen by some people as sort of callous? >> no, and i don't think it was callous. >> and more than that, tex's sister dixie says, it was necessary. diane was wealthy by any standard, but her estate was cash poor. selling her belongings raised money for diane's bequests. >> she left money to people that she didn't have. so the estate attorney said the quickest way to raise the cash is sell her things. >> so the idea to sell everything, that came from the attorney, not from tex? >> oh, absolutely. >> between the estate sale, the memorial service and those nonstop rumors, it would have been easy to forget that the police were still quietly investigating diane's death. on december 21st, 2016, they made their move. tex mciver was arrested and charged with involuntary manslaughter and reckless conduct. those were, to be sure, serious charges, but they also made clear police believed tex didn't mean to kill diane. tex had dodged a murder charge, but his sister said tex didn't seem to get that. >> he just kept saying, but it was an accident. i said, but someone died. i don't know what he thought. who knows what was going through his mind at that point? >> tex mciver was released on bond, and while he seemed clueless about why he was charged with anything, diane's friends and colleagues wondered if he had been charged with enough. >> i was angry. it is like i didn't care -- i didn't -- i didn't care what i was angry, i didn't care what happened to him. >> in the months since diane's death, dani jo had become suspicious about tex's behavior during that final, fatal drive. so we asked her to take us along the route they drove that night. this is the underpass where tex says he first began to worry about the homeless people in the area. dani jo says there was no danger. >> nothing that would have kept you from driving away, going on your way? >> no. >> just a few minutes later we came to where they made that fateful stop in midtown, atlanta. and it was, says dani jo, just a stop. >> we were sitting at a red light. >> no bump? >> no bump. >> you know the rest. diane was shot and dani jo took off for the hospital. she says she was frantic, but tex, she says, was calm. >> as a matter of fact, at some point a little bit farther up he told me to slow down and be careful, that there might be people out here with -- walking with baby carriages. >> wait a minute. his wife is wounded in the front seat here by his hand, and he's telling you to slow down? >> yes. >> at the hospital diane was already in surgery when police showed up, and that, according to dani jo, is when tex said the weirdest thing. >> he looked past me and he said, i don't trust these guys. i hate to see you get wrapped up in this, dani jo. i've seen how these things can go down. and he said, you just need to tell them that you're down here as a friend of the family. >> wait a minute. you're here as a friend of the family and not as the person who was driving the car when the shooting happened? >> right. and so i leaned down again. well, i said, tex, i just drove you in to the emergency room. looks at me and he goes, well, they don't know that. i thought, what do you mean they don't know that? >> dani jo shared her misgivings with diane's co-workers. they were now convinced atlanta police hadn't dug deeply enough. jay grover was skeptical of tex's claim that the gun had just gone off. >> this does not make sense. logically it just doesn't make sense. what are you saying? something wasn't right. >> it turns out fulton county prosecutor clint rucker was thinking the same thing. >> there was no malfunction with the gun at the time it was discharged. it was in perfect operating condition. it had 12 pounds of pressure required to pull the trigger. >> meaning it is not easy to do. >> it is not easy to do. it became very clear to me this had to be an intentional act. >> diane's colleagues gave the da her computer and files, hoping rucker might find more evidence. >> and that is when the evolution of the motive then developed. >> rucker's investigators found documents suggesting tex was in financial trouble. what is more, diane's colleagues revealed she had been working on a new will. rucker wanted to find that will so he got a search warrant for the ranch and condo. no will turned up but something else did, a glock in tex's condo. that was a violation of his bond, so tex went back to jail. the next day rucker filed new charges and the tex mciver case escalated from careless accident to malice murder. it was according to tex's sister, dixie, preposterous. >> if you were going to kill your wife, is that how you would choose to do it?

>> no. >> if i handle it like this in any way, will it just go off? >> no. >> their godchild -- >> it took the prosecution 66 witnesses and 16 days to make its case. the defense team had a shorter, simpler case, but they also had their hands full with a client who hadn't always acted in his own best interest. >> mr. mciver was just hellbent on defending himself at times. >> was one of your advice to him to please stop talking? >> absolutely. >> like i won't represent you if you don't stop opening your mouth? >> much more than that. physical consequences. >> amanda clark palmer, don sam annual, three of the best lawyers in georgia were adept at using prosecution witnesses to bolster their defense. for example, they got the state's forensic's expert to agree in some circumstances the shooting could have indeed been unintentional. >> and, again, this weapon as well as any other weapons can be unintentionally discharged, correct? >> it can be, yes. >> tex's attorneys pointed out how prosecution witnesses testified tex and diane were happy together and planning to stay that way. >> as far as i can tell you, it was a very good marriage. >> they were very close, very affectionate. >> it was quite obvious they were very much in love. >> in fact, it was a prosecution witness who knocked down the argument that diane was going to call in that big loan and foreclose on the ranch. her colleague, ken rickert, testified that while diane could have done that she probably wouldn't have. >> i'm not sure that that would have ever happened. diane would have avoided that, i believe, at all costs to try to keep the marriage together. >> as for the allegation of a second will, that was easy. >> it doesn't exist, that's why it was never produced. >> the receptionist testified she never actually saw the will, and prosecutor clint rucker admitted he never did find it, and he tried. >> you never produced the second will? >> never produced the second will. >> an er doctor called by the prosecution gave the defense one of the most intriguing bits of testimony. she said diane told her the shooting was an accident. >> and in the end it was clear she was saying he had the gun, correct? >> yes. >> in her coherent state she said it was an accident? >> yes. >> but the bottom line for the defense was that the murder scenario itself was absurd. >> we're going to drive back to atlanta, to our condo in buckhead, and on the way i'm going to 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 is called confusional arousal. >> is that normal? >> the defense called the sleep specialist who had been treating tex 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 it is like hitting the lottery. >> he is going to vilify tex mciver, we're 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. why hide your skin if dupixent has your moderate-to-severe eczema or atopic dermatitis under control?

>> we felt if it was cocked, then, yeah. it could have fairly been easily been done by accident. >> the jury asked to see the video from the video. tex's attorney steve answered their question. >> pulled the hammer, pulled it back. >> the only evidence the gun was not cocked came from tex's own attorney, but even than 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. tex's sister dixie and his friend 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 -- >> we find the defendant guilty. >> killing someone while commit a felony. >> guilty of felony murder. >> possession of a firearm in the course of a felony. >> guilty. >> trying to influence the witness dani jo carter. >> guilty. >> in lay terms the verdict meant tex didn't mean to kill diane but he did mean to shoot her. >> 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 mistake in the verdict, and it is the result of a compromise and i think it is just plain wrong. >> tex's sister dixie is still stunned. >> to think that one moment in time you lose your wife, you lose your friends. you lose your money. you lose your house, you lose your career, you lose your dignity, and you lose your freedom and your future. >> only once did tex mciver speak in court, in a rambling statement before sentencing, tex declared how much he'd miss his godson austin. the food at chick-fil-a, and then finally his wife diane. >> but if i might just say to her directly, i know she's here, i feel the presence as i'm speaking to you, darling, you have brought me more joy fulfillment few men on this earth have ever known. thank you, and until we are together again. >> tex mciver is now serving a life sentence. his attorneys filed a motion for a new trial but at 76 years old, freedom for tex is a long shot. and dani jo is okay with that. >> she misses her friend diane every day. >> i dream about her a lot. i miss her. >> for months after the verdict, the beloved mciver ranch stood vacant. extravagant parties and celebrations just memories. diane's wedding dress hung there in the closet alongside a shrine of sorts tex made in her honor. remnants of a marriage many thought was as good as it gets, but as tex settled into prison, an auctioneer sold it all to the highest bidder. that's all for this edition of "dateline.
