by a gunshot, then a frantic call to police. lisa jennings was dead. the question for detectives was, did she take her own life or was this murder? here is keith morrison with "a crack in everything." ♪ it was his secret that started it, a secret gift. it was christmas eve in the year 2006. a little farm not far from a little town called buffalo. buffalo, missouri. and on that farm in the fine, new house brad and lisa jennings had built for their family, the stockings were hung, the children were snug in their beds, and lisa was sitting up very late, drinking wine and crying. meaning? well, who knew. but for one thing, with lisa in

the way brad couldn't sneak that secret of his into her stocking, which is what started it, the flaring argument, the slamming doors, the sudden silence. before amanda woke up to the sound of her dad on 911. >> and he's very hysterical, you know. he's -- he's crying, can't really say anything other than get here quick, get here quick. i heard that two or three times. >> such a complicated tale with its secrets and lies and shifting loyalties, and here, of all places, this throwback to an idealized past. >> we hunted mushrooms, we picked up walnuts. >> they were inseparable children, brad and his older sister marsha. >> he was my playmate. we depended on each other. >> marsha became a nurse, brad ran the farm, the center of their family since 1853. that christmas 2006 brad and

mostly later in the evening, at night after they had been drinking, there would be yelling and maybe slamming doors, things like that, but just arguing about anything, nothing. >> i never really thought too much about it. >> anyway, now it was that calamitous christmas eve 2006. >> christmas eve we would go to my grandma's there in town. >> and then back home, games and stocking stuffing and, of course -- >> i wake up real early and open all of the presents. >> lisa had no idea that brad had bought her a $3,500 diamond ring, got the kids to help him pick it out. back from grandma's he waited for his chance to hide it in her stocking, but lisa kept fiddling on the computer and the kids were playing a board game.

>> i think it was "monopoly." >> we just played downstairs for a while and then eventually went up to our rooms. >> it was well after midnight when they heard the raised voices downstairs. >> i heard, you know, the yelling and everything, a normal fight like they would always have. >> and then a door slammed, which meant that brad had gone out to his workshop to cool down, but laci, home for the holiday, was furious. another fight and this one on christmas eve no less and as usual over some stupid little thing? she was done. >> and so my sister decided to go downstairs and get into it with her. i think one of the last things i remember my mom even saying was something like, i would never disrespect my parents that way. >> laci was just fed up, was she? >> yes, she just couldn't believe they would fight on christmas. >> then more door slamming and laci was out of there. >> she went back to her house in buffalo. >> so by the time she left your dad was outside in the workshop, although you didn't really know where he was, right? >> well, he was outside.

explanation. >> so the prosecutor says it is a logical inference from the facts of the case that mr. jennings after he shot his wife, before he called 911, he washed his hands and washed his forearms. >> and blood evidence? investigator nash was the expert the state put up, and he said that in his expert opinion the way the spatter hit the wall and brad's black bath robe and lisa's hand it left no doubt that brad fired the fatal shot. but why would he do such a thing? an age-old reason, said the prosecutor, lisa wanted out. >> the prosecution at trial wanted to show that she was intent on leaving him, and she had an application at an apartment complex where laci had lived. >> lisa wouldn't end her life, said the state, because she was busy improving it.

she had bought nice clothes, had recently had cosmetic surgery. >> the state presented witnesses that said she was in good spirits and it is unlikely that someone who has cosmetic surgery and is feeling good about themselves would take their lives. >> the defense didn't mention that lisa's father committed suicide or that she herself attempted suicide back in high school. no secret in town back then. and nobody brought up the rumor that lisa was having an affair. but one curious thing did come up. the defense attorney in his closing argument made a rather fascinating point about the bath robe brad was wearing when lisa was shot. >> the defense attorney in his closing argument said, they had that thing for two years. i don't know why they didn't test it for gunshot residue, but they didn't. so we could wrap this up in a heartbeat whether he did it or not if they had tested that. >> now, that was interesting and a very good point. after all, if they found residue

on the bath robe it would certainly point right at brad. but the moment passed. the case went to the jury. and two hours and 24 minutes later, they found brad guilty of murder. and where else would this happen? they let him go home one last night before the sentencing began the following day. >> the next morning he asked me to drive him back, and i think that's one of the most difficult things i have ever had to do. >> did you want to just say, "let's go somewhere else, brad, let's just drive to mexico or something?" >> no, that's not who we are. and i told him that i would fight with everything i had in me to correct it. >> but what could one lone woman do? no legal training, no contacts, no pull.

>> and they didn't send them to me. >> so she wrote to them again. >> i said, all right, i know they're there, i have photographs of it, i know they're there, send me the results, and then they sent them. >> and? the tests were conclusive, there was no gunshot residue on brad's black bath robe, just as there wasn't any on his hands on the night lisa died, meaning brad almost certainly did not fire the gun that killed lisa. but why didn't lead investigator dan nash reveal that? well, he said he never received those results. plausible? >> not in a heartbeat. no, i was a prosecutor before this. my spouse is a police officer. dwight is a police officer. we know the care that goes into building a case, and that's not a step that you skip. dan nash had specifically asked for that test to be done. >> so by now dwight was looking carefully at dan nash.

he talked to a retired judge. >> and he made it very clear that he had a lot of problems with mr. nash's reputation for truth and honesty under oath, and from there we started interviewing former prosecutors, and the number of former court personnel who expressed concerns about his reputation for truth and veracity. >> remember how at the trial nash was presented as a blood spatter expert? he wasn't. in fact, nash had not even taken a basic blood stain analysis class when he investigated lisa's death. he took a 40-hour course the following year, but was still not an expert when he testified at trial. dwight sought out the best in the field. >> i found two of the world's most renowned blood spatter experts. >> he sent the crime scene photos to both of them. >> and they both independently came to the same conclusion.

>> that dan nash was quite simply dead wrong. one of them wrote, "the blood stain evidence and the presence of gunshot residue on the right hand of lisa jennings are consistent with a self-inflicted gunshot wound." but as any lawyer will tell you, undoing a jury's guilty verdict is well nigh impossible. so what now? coming up -- a life interrupted. >> he missed out on me turning 16, me getting married. i have a kid now. he missed that. >> wow, wow. >> he missed out on a lot. will brad jennings miss even more? when "dateline" continues. our new house is amazing. great street, huge yard. there is a bit of an issue with our neighbors fencing. neighbor 1: allez!

welcome back. brad jennings was serving 25 years for murdering his wife. but his sister was convinced he'd been wrongfully convicted. she hired a team of private investigators who uncovered stunning new evidence, including the elusive gunshot residue test on the bathrobe brad wore the night of the shooting. they knew the odds of overturning the verdict were low, but brad's family would stop at nothing to find justice. with the conclusion of "a crack in everything," here's keith morrison. >> reporter: dallas jennings felt like a cheated young man.

his father in prison, when neither he nor amanda believed for a minute that he killed their mother. >> he missed out on my turning 16, my driving for the first time, my graduation, me getting married, i have a kid now. he missed that. >> wow. >> the birth of his first grandchild. he missed out on a lot. >> reporter: but brad's sister, marcia, was still determined to bring him back to that world he was missing. and with investigator dwight's help, she finally found a father/daughter team of attorneys who seemed to understand the case. and the family. >> these were just salt of the earth, small-town, country people. and they were stunned at the way the system had worked against brad jennings. >> reporter: first bob and liz ramsey read the trial transcript. >> the first thing that jumped out at me is i don't recall

seeing the defense attorney do so little for his client, in my 38 years of practicing law. >> come on. not the worst, surely. >> it was certainly one of the worst. >> reporter: but what also jumped out was the work of that highway patrol investigator, dan nash. confronted about the unrevealed gunshot residue test that might exonerate brad, nash said he never saw the report, said it never made to his desk. >> if that test had been positive, would it have been lost in a fax machine? >> it's just incomprehensible that he wouldn't follow up and say, hey, what happened to my gunshot residue test that i ordered? well, he was either grossly negligent, or he suppressed it deliberately. >> reporter: noey about y aboe question about. it the issue of the test was huge. >> i thought, it's a classic brady violation. the kind of evidence that makes

a difference in a trial. >> reporter: so they elected to shoot for the moon. their one chance to overturn the jury verdict -- a habeas petition that claimed withheld evidence could have changed the result of the trial. >> i don't promise anything to a client other than i'll give you my best shot. and all i told him was, this gives you a shot. >> reporter: vanishing few such petitions ever go anywhere. still they filed and waited. and against all odds were granted a hearing. >> we were very excited. >> yeah. >> but cautious. it was almost like this little dim light at the end of a tunnel. >> reporter: this was the hearing -- in november, 2017, almost 11 years after that terrible christmas eve, here brad's attorneys revealed the gsr result that suggested his innocence and the experts'

findings that did the same, and witnesses who questioned the honesty of detective nash. >> i think that his credibility was put at issue for the entire hearing. >> reporter: lawyers from the missouri attorney general's office were there, too, and told the judge that what the defense came one would not have changed the guilty verdict their case was so strong. we wanted to hear from thetern's office from sergeant dan nash and the highway patrol and all declined our requests. and then months went by, and they all had to wait for the judge until finish 8th, 2018, finally a ruling. >> my first reaction was to go right to the last paragraph and see what the result was. >> see what the result was. >> uh-huh. >> the last sentence of his order is, "at a minimum, the suppression of the gunshot residue test undermines confidence in that verdict." >> reporter: conviction

overturned. >> it's the first time that we had had a positive outcome. it was wonderful. >> reporter: the next day on the judge's order, brad jennings walked out of prison after 8.5 years. and into the arms of the people who never for a minute gave up on him. >> love you. >> hi. guys. >> it's the kind of stuff that you dream about in law school. and i firmly believe that bad is innocent. so to walk him out was one of the greatest honors of my life. i'll never forget that day. >> we had all waited so long for it and wondered if it was ever going to happen. it was one of the best days of my life. >> it was really awesome to see him walk out, you know. that was the -- knowing he was going come home with us, that was amazing.

>> reporter: that ride home had to be quite something. >> it was. >> it was weird. it was the first time my dad's ever seen me drive. i drove him home. >> reporter: brad jennings was a man of few words when he met us a few weeks later, as if he was still afraid to believe it and well go. but we talked a bit about that christmas eve and the mystery of what a upset lisa. >> she was crying. that's one thing i asked her, why she was crying. >> reporter: she couldn't tell you? didn't want to tell you? >> didn't want to talk. didn't want to say anything. >> reporter: wasn't until years later he said that he learned she'd been having an affair with her boss, and that man had just broken it off, meaning she was also out of a job. >> she had told me she wasn't coming back teamwowork the day this. >> reporter: he deidn't understand it then. but now, maybe that was an answer to his long-ago question why did she end her own life.

once he might have confronted the other man. now, nothing to be done. >> i don't know even know where he's at now. that business shut -- closed down now. >> reporter: in july, 2018, the state attorney general's office announced it would not retry brad. as for the once-close family, when we last spoke with them, they remained badly split. lisa's sister, shawn, and daughter, laci, still believed brad was guilty. and for brad -- >> it was like starting over again. >> reporter: and he clings to his kinds and his sister, his mom, and those who believe in him, to his ancestral farm and his other longtime love, the old chevelle. >> i knew brad was innocent. the own thing i've ever wanted was for finally everyone to hear the truth.

that's all for this edition of "dateline." i'm craig melvin. thank you for watching. u for wag i'm craig melvin. >> i'm natalie morales. >> and this is "dateline." >> oh, god, please. >> ma'am, okay. >> oh, god. >> ma'am. >> i just knew that she was gone. >> she was a bright young mom-to-be. >> she was beautiful. confident, strong. >> it was the smile that got me. >> moving on from a messy divorce jumping into a new romance. no one could believe it when they found her. >> they're saying it was a homicide. >> then police found something else. revealing recordings. >> everything changed like instantly. it's weird. >> brittany is essentially
