your spouse isn't a crime, is it? that would come next. >> my god. oh, my god. >> every emotion possible all in one second. >> oh, my god. >> murder in the dark. who was behind it? who would pay? >> when you see him on the video, he's armed and ready. >> two couples, two families and a single moment that shattered it all. >> i knew one day that this was all going to come out. >> a marriage, a murder, a mystery. i'm lester holt and this is "dateline." here's keith morrison. >> look at this place now. so ordinary with its pharmacy, it's grocery store, it's carefully tended parking places so like to suburban strip malls from bismarck to bakersfield but that night, that cold night a heat gathered here, sweet terrifying, loomed. >> for the longest time, i couldn't go anywhere because i am thinking everybody is looking at me. >> this is the story of two married couples of the advice they can offer others now that it's too late for them. >> i think if i could tell them anything, it would be put your family first. >> but of course that's not what happened. and this parking lot, there will be a body here before we're done. >> oh my god! oh my god. >> careful when you stir the hot pot of desire. this place is meridian, idaho. this is where they got to their perfect place. the end of their rainbow. it was 2006, and luck was on their side. they had just moved from southern california and they were happy. they were fulfilled at work. they had two beautiful children. they had everything they ever wanted. they were rob and candy hall. one of those charmed couples who had fallen in love at first sight in their case first sight met admiring each other in the gym. >> i think that weekend we went out and we never stopped. >> what was it about that relationship? what was it about him that you liked so much that was so good? >> we just connected instantly. >> by the time rob and candy moved to idaho, they had been together for years, had two teenage daughters. rob landed an excellent job as a computer specialist at the sheriff's office specializing in vehicle locaters inside squad cars. >> he loved every minute of his job. >> as if it was a sign of this is where they longed, candy's job as a paralegal took off as well. she could sell her skills to anybody who walked in the door. >> it didn't hurt that she was pretty. >> no, it didn't. and he had co-worker idolized candy. you became close? >> she was like a mother to me. >> it was all just about perfect and then who knows why these things happen exactly. they just do. and no one imagined why would they. how this thing was going to end. about eight months into his new job, rob started traveling for work. nothing unusual about that of course. but soon he seemed to be staying away from home a little longer than he really had to. started snapping at her too, candy said, about little things. not like the old rob at all. so at this point you begin to suspect something. >> i start thinking what is going on? why are you acting like this? >> and then one night after a late flight in from california, rob laid down beside his wife in bed and it all came tumbling out. >> he just started to cry. he said, i'm having an affair. and i laid my head on his chest and i said, rob, please, just fix it. >> you didn't get upset? you didn't yell? you didn't scream? you didn't cry? you didn't do anything. >> that's what shocked him. the typical response is get the hell out. >> you throw the clothes out the window. >> the last person on this planet that you would think to have an affair would be robert. >> of course it was devastating, crippling. every day she went to work and every day solphia saw her frien turn herself inside out. >> i watched her go through misery. sobbing in her hands daily and just trying to figure out what this woman had that she didn't. >> did she still love him? >> yes. dearly. >> wanted the marriage to continue in spite of the affair? >> she did. she didn't want to believe in her head that he found something in this woman that wasn't in candy. >> he felt bad about it. agreed to go through counseling with candy but after he confessed to you and you said fix it, he didn't. >> he didn't know what he wanted. >> come on. he wanted to keep going with the affair. >> i for sure told him to stop. >> stop right now or i'll stomp my foot and hold my breath and he kept doing it. >> yeah. it was my fault. he had a void because of me. that's what i was thinking. >> what do you think the void would have been? what did you think it was? >> i was boring. >> boring old candy hall. rejected apparently unlovable and nearly 40. and then one day at work candy was introduced to a recent law school graduate who was looking to staff his new office. a boyishly handsome smart as a whip cocky young lawyer. his name was emmit coregon. >> my friend said you have to meet candy. she's as passionate and aggressive as you are and she would be great for you. >> something lifted in candy hall. by the time those words left her friend's mouth, candy knew she just knew. how about you? think you know where this is heading? when we come back, candy hall has a decision to make and it will have consequences she never intended. deadly ones. >> the text popped up and rob read it. rob says why are you texting my wife?

>> sometimes too much energy but that's kind of one of the things i loved about him. >> just like kandi and rob, ashley and emmett met in a gym. in college in utah in 2003, also inseparable from that moment on and they certainly made a striking young couple. they were married after just six months together. made their vows before god and the church in the lds temple. >> i think i'm ready to be a parent. >> first came twin girls followed soon by a son and then another daughter. >> he loved being a dad as much as i loved being a mom. >> in the winter they went skiing, sledding. in the summer they camped and swam at the lake they so loved. they made memories. ashley never doubted this was how their life was supposed to be. she was pregnant with her fifth child when her ambitious husband opened his law office in the fall of 2010. and made the fateful decision to hire a paralegal named kandi hall. not that he had any idea he was sealing his fate of course anymore than his wife ashley understood his private motivations. did you suspect she was involved with him? >> with emmett? no. >> why? >> the way he described her was an older woman who he looked up to in a motherly way. he said she just believes in me. she thinks i'm going to be a great lawyer. >> you saw her and she was an older woman. >> she was almost 40. i was 28. it wasn't something that i felt like a competition of i guess. >> but for the many reasons that plainly escape those who aren't seated smack on the hot stove of desire themselves, emmett and kandi thought otherwise. so they tried to keep their hands off each other for a little while but if they believed they were hiding their obvious infatuation, suddenly messy hair and hastily rearranged clothes, they were only fooling themselves. >> i noticed a significant change in her attitude. it went from being depressed about what rob had done to happy. >> spring in her step again. >> oh, yeah. >> such timing. now that robbed seemed to want to fix their marriage, kandi became an honesty in pretense. honesty took a holiday. >> i was living in a lie. being in an affair is one big lie. you lie about everything. >> and she lied to herself too. you were thinking of you and he together striding across the bow of the "titanic." this is going to be it for you forever. >> yes. >> one night a couple months into the affair, events suddenly ticked measurably toward their deadly conclusion. around bedtime, kandi received a text from emmett and she couldn't hide it. it said i wish i was there with you. he was angry. what is this? i said i don't know. he calls emmett. why are you texting my wife? at this time of night. >> emmett's answer two minutes later he showed up at rob's house. they talked like duelling lovers out on the sidewalk. and then rob came back inside. rob tossed my phone up on our bed and he said you win. i can't compete. he's young. he's good looking guy. he's an attorney. you make him a lot of money. what good am i? he was just devastated. >> now you got yourself a pretty complicated life at this stage. >> yeah. >> of course that february 2011 emme emmett's life was complicated too. ashley could see how stressed he was. didn't understand it. that or why he seemed to avoid coming home. >> there was one time when my son asked me if he lived with us anymore and later in the bedroom he was, like, what's that all about? i was, like, well, we miss you. he just kind of yelled and screamed and left. >> ashley thought maybe it was her fault. she went to marriage counseling. emmett refused to go. >> i had felt really pushed away and was trying to find an answer and tried to surprise him by cleaning out his car and found a weird envelope. >> a weird envelope? >> an envelope that was some sort of pill. i researched online and one of the side effects was problems with intimacy and sexuality. i thought maybe if he was doing that, that could explain why he didn't necessarily want me. >> did you take it personally too though? >> you want to be everything that they want. it was hard not to take personal. >> especially when emmett who had been working out more and more announced he was going to a fitness competition in ohio on their wedding anniversary. what did that feel like? >> lonely. he calls and said happy anniversary. i'll call you later but didn't call back. and the night before he came home, my oldest son, who had just turned 4, was screaming one night for probably two hours. my dad is going to die. my dad is going to die. he's going to die. i held him. i tried calling him but he never answered his phone. it was a very strange weekend. >> strange. strange is not a big enough word to describe what was about to happen. >> coming up -- >> i literally was like, emmett, please do not leave. he said i'm leaving. >> a secret meeting at walgreens and something will go horribly wrong. i said i'm not doing this. it was the 11th of march, 2011. this was it. the big event. d-day you could say. it was early evening. cold as the sun went down in meridian. cold and bleak and in two homes in particular it was very bleak indeed. kandi hall arrived home from work to find her husband, rob, packing boxes to leave. what other reason could there be? >> i knew we were probably coming down to the wire. >> you're having unfair fights that married couples have all the time. they betray each other with abandon and wonder why it doesn't work out. >> the thing i never wanted to face was the hurt i was going to cause on so many people. i knew one day that this was all going to come out but the way that it usually ends up. >> now you can only look back and wish it had turned out that way. around the same time across town perhaps two miles away, ashley corrigan made the mistake of telling her husband that in desperate state of worry she asked family members to pray for them. >> he said, your family? i hate your family. i could kill all of you. i grabbed his face. you know what? i love you. i'm not going anywhere. i don't care what it is. just tell me what's happening. and i don't know. i felt like that was the last chance. he didn't take it. he didn't open up about anything. >> that night though a trusted family member who agreed to help counsel the couple called and emmett answered the phone. >> he went back into our bedroom and i could hear everything he was saying because the baby monitor was on. the hard part then was not a word he said was true. >> what was he saying? >> i think she might be sleeping with person. she says i'm the worst father ever and things that i know i have never done. so when he walked out, i flipped the baby monitor off and i said, oh, how did it go? it went good. he thinks you're as crazy as i do. okay. well, do i get a turn? he said i don't care what you do, but you're not using my phone. emmett said, hey, i'm going to run to walgreens, and i'll be right back. i put the phone down and i literally was, like, emmett, please do not leave. he said i'm leaving. >> you must have felt like your life was flying apart and you didn't know what to do. >> i felt like maybe this is the grand finale. >> he needed a wake-up call. >> he needed a wake-up call. >> careful what you fish fwish . getting late now. over at the hall house, kandi had been talking to her husband, rob. maybe he shouldn't move out. maybe they should try to fix their marriage and make it work somehow and then right in the middle of that, she suddenly told him she had an errand to run. couldn't wait. guess where? >> i said i need to go to walgreens. i'm going to go through the drive-through. i'll be right back. >> here's kandi's explanation as to how the meeting was arranged. >> he text me and said what are you doing? i said i'm going walgreens. he said i was just there. meet me there. >> and then what happened next you can watch it yourself right here on surveillance tape. >> i go to walgreens. go through the drive-through. and i pull around and i park my car. he pulls up and i get in his truck and we go to fred myer. >> there they are again getting gas at fred myer when emmett opened the truck's rear door. >> he pulls out all of these prescription bottles. i said what are you taking? he said, well, if you don't want to grow a penis, don't take it. then he got back in the truck and we drove off. >> from there kandi and emmet pulled into a secluded spot and had sex under a street light and that's where they were tangled up in each other when her phone rang. her daughter coming home from a date saw her car in that parking lot. >> mom, why is your car at walgreens. i called dad. okay. i'll be home in a minute. >> too late because now the wind was up. rob, the unfaithful husband, had to know and now he was the aggrieved spouse and as kandi talked to his daughter, here he was in his pickup truck coming to walgreens to look for his wife. >> phone call from rob. are you with emmett? i go -- took a deep breath -- i said, yep, i am. looks over at me and takes the phone away from me and says what's up, chief? he says, yeah. wait right there. we'll be right there. you wait right there. and that's when i said, no, knock it off. we're not doing this. he's like, oh, we are doing this. >> there are moments in life when big choices are made. this was not a good one. >> coming up, a late-night rendezvous turns deadly crime. >> oh my god. i'll never forget. ever. septic system breakdowns affect over 1 million homes a year... and can cost thousands of dollars to repair. thankfully the powerful dual action formula of rid-x has enzymes to break down waste... and time-release bacteria to reduce tank build up. rid-x, #1 in septic maintenance. here at a walgreens drugstore in meridian, idaho, just before 10:00 p.m. on a friday night in march, 2011, time was up. devil wanted his due. robert hall was a man on a mission as you can see on these store surveillance videos. rob parked his pickup truck. roamed the beauty and cosmetic aisle looking for his wife, kandi, who was also in a pickup truck with her lover, emmett. here you can see rob leaving the store looking at kandi's parked bmw and then strangely getting back into his own pickup truck pulling out and then reparking it on the other side of kandi's car. curiously his door now just out of range of the store surveillance camera. this is when he made that phone call. the one in which kandi confessed she was with her boss, emmett corrigan and he said to rob, what's up chief? here was emmett's truck speeding through the parking lot. still time to stop this if wiser heads had been in charge but they weren't. nothing wise about what's coming. >> i see rob in his truck. he has just this look on his face, like, oh, man. i get out of the truck. but then emmett gets out and then rob gets out and walks over to us. >> this is just the sort of moment in which a person might have wanted to cool the overheated atmosphere. control the spitting anger. chosen words carefully. that is not what happened. >> rob is standing next to me. he's, like, what are you doing out with my wife at 10:00 at night? and emmett said, rob, she doesn't want to be with you anymore. okay. she's done. i mean, really, rob, what did you make last year, maybe $40,000? what did we make last week? $27,000. in one week, rob. that's how much i make. you don't make anything. >> nasty, of course. arrogant like a thoughtless young buck that needed to be reminded of something. >> rob said what about your kids and your wife? she just had a baby. they're at home waiting for you and you're out with my wife. >> at that moment emmett's eyes got huge and he pushed himself off his truck and went up to rob and pushed him really hard on his chest. >> and then the climax. the confrontation that had been building for weeks. >> that's when i said enough. that's enough! you get in your truck. rob, we got to go. as i was walking to my car, another car came by. i had stopped and at that point i hear pop, pop, pop. i didn't know what it was. i didn't know if that war just backfired. i had no idea. i stopped. what was that? and all i see in my peripheral vision right here is rob covered in blood like someone poured a can of red blood all over him. >> frantically kandi's fingers found the numbers 911. >> oh my god. robert! >> the pistol went flying somehow. no one disputes that. there it was lying on the pavement between two men. both shot. one alive, one dying. and kandi hall entered that twilight zone where memories are made that can't ever be erased though as you and the police department and lawyers and the judge will soon see, they can certainly be amended. what we know for sure is that she rushed to the prostrate body of one of those two men. >> i gave him a kiss on his cheek. i will never forget ever. he took that last deep -- it was very surreal. he was turning gray here to here to here. i didn't have much time to think of much other than thinking to myself, oh my god. he's dead. >> but which one and what just happened? a tragic lapse in judgment, a thoughtless but unintended crime of passion or was it murder in the first degree? spokesman i have to look my so bbest on camera.sing whether i'm telling people about how they could save money on car insurance with geico... yeah, a little bit more of the lime green love yeah... or letting them know they can reach geico 24/7 using the latest technology. go on, slather it all over. don't hold back, go on... it's these high-definition televisions, i'll tell ya, they show every wrinkle. geico. fifteen minutes could save you fifteen percent or more on car insurance. >> with hotwire's low prices, i can cross even more places off my travel wish list. this year alone, i hit new york and texas. see, hotwire checks the competition's rates every day so they can guarantee their low hotel prices. >> men: ♪ h-o-t-w-i-r-e, hotwire.com. ♪ i started a week ago going pro with crest pro-health. since i've been using crest pro-health, i've noticed a huge improvement.

there's been an accident and your daddy's spirit left his body so he won't be on earth with you anymore. they all just kind of stared at me, like, what are we supposed to do now? >> what now indeed. and that very moment a few miles away, rob hall was in a hospital bed recovering from a grazing gunshot wound to his head, the result of a botched suicide attempt after rob put two bullets from his semiautomatic pistol into emmett corrigan, one in his heart, one in his head. and over at the meridian police station, kandi hall's clothes still covered in blood was telling the first of several different versions of what happened in the parking lot. quite unprepared of course for the public torrent about to come down on her head. suddenly you're thrust into the public eye big-time as a woman who is at the center of a love triangle. what is that like for you? >> it's scary. for the longest time i couldn't go to the grocery store. i couldn't go anywhere because i'm thinking everybody is looking at me. everybody knows who i am. >> everybody knows what i did. >> yes. but it did happen and i own it. >> there's something else that happened. on the night of the shooting kandi rushed to kiss her dying lover. she rather soon was back in her husband's corner as his chief supporter especially when robert hall was charged with premeditated first-degree murder. >> we felt that the evidence supported that he planned to go to that walgreens and do exactly what he did when he got there. >> this was no sudden crime of passion, said the prosecutors. idaho deputy attorney general -- >> this is case of a man hunting down his wife's boyfriend and waiting 17 minutes to have the opportunity to kill him. >> thank you, your honor. >> in fact, as they made their case for the jury, prosecutors portrayed rob as an angry man, furious about his wife's affair. a man who called emmett's law office repeatedly to berate kandi so loudly that others heard it all. >> statements such as you're a whore and why are you with him? >> the night of the shooting, prosecutors played those surveillance tapes from walgreens showing rob arriving at the drugstore 17 minutes before the confrontation. walking through the aisles looking for kandi. all the while with a pistol. not the one he usually carried but the one kandi gave him tucked in his pocket. and then the jury saw emmett and kandi arrive in the parking lot and eight minutes later heard kandi's 911 call after shots were fired. >> oh my god! robert! robert! >> what happened? the prosecutor said the secrets of the shots told the story. two quick shots. a pause and then one more. >> our theory all along was that rob hall had executed emmett corrigan with two successive shots, turned to face his wife, attempted to commit suicide with the third shot. >> the theory backed up by forensics. the shots were fired from close range two or three feet. there was a heavy concentration of gunshot residue on only robert hall's hands and only one man's dna on the trigger guard. >> the dna matched that of mr. hall. >> i think that rob hall went to the walgreens in order to confront emmett corrigan, that he took a loaded gun and rob decided that was his opportunity to get his kandi back by killing emmett. >> why did he talk to emmett for eight minutes before he fired? the store was closing, said the prosecutor. people were going home. >> i think he waited until there were no eyewitnesses and he executed emmett corrigan. >> a tidy theory agreed the defense but completely wrong. >> this fight was started by emmett corrigan. >> rob was a nice guy, said the defense, and it was emmett that was out of control. emmett that kept steroids in his truck. >> explosive temper. >> what really happened? rob didn't testify that a doctor backed his claim that because of his head wound he couldn't remember so the defense offered a theory that emmett started a fight and the gun fell on the ground and emmett grabbed it and shot rob and then rob fired back in self-defense. the courtroom came to a halt. every head turned when a star witness took the stand to support that theory. >> would you please state and spell your name for the record. >> kandi hall. >> kandi repeated the story of emmett becoming enraged and hearing the two men scuffle before she walked away before she heard but did not see the shooting. the only problem she told the police a very different story the night it happened. >> you told detective miller that night that you didn't see or hear a physical altercation, isn't that right? >> i don't know. i don't remember. >> kandi changed her story about so many things all helpful to rob's case. >> i'm trying to clarify that your story changed after speaking with your husband. >> things were remembered after talking to my husband. >> later the judge made a comment outside of the jury's presence. >> he said in all of his 30 some years on the bench he had never seen a witness so thoroughly discredited. >> before she left the witness stand, kandi expressed her love and sorrow for the man she cheated on yet still loved. >> he knew and he still knows in his heart that i never stopped loving him. you don't just stop loving someone. >> and watching it all, emmett's wife, ashley. >> you watched as kandi testified and what was that like? >> it's hard to hear her stand up there and tell her husband how sorry she was and how much she loved him because ultimately it was because of them that i didn't get that chance. >> and rob hall's version of events, he's about to tell you. the very first time he has spoken of this. but first, it's up to the jury to determine the wages of sin. >> coming up -- >> i wish i had never gone there that night. >> a husband with a stunning story to tell. >> last thing i remember was the gun pointed at my head. >> whose story will the jury believe? once he had everything he wanted before he and his wife scratched the itch of wanting more. and now a jury was about to tell robert hall whether for the rest of his life he would have anything at all. he had a small advantage over the jury. hall did not testify but he talked to us. his first ever interview to tell us he was sorry about what happened, yes, that but also to tell us that it wasn't his fault. >> the notion that i brought a gun there to gun down emmett corrigan, i didn't bring a gun there to gun down emmett corrigan. >> hall's version that despite what you heard, he did not even know for sure that emmett was having an affair with kandi. that in the parking lot, emmett was the aggressor, pulled him down from behind by the hood of his sweatshirt. >> i don't think i made four steps before i was ripped off my feet. when i hit the ground, first thing i thought was my cell phone hit the ground. and i looked over and it was my gun. he reached down and grabbed my gun and we just struggled over it. last thing i remember was the gun pointing at my head and the feeling of being hit upside the head of a baseball bat and i remember seeing everything black and gray. and that's all i remember. until sunday in the hospital. >> in that moment of extreme anger and passion, crazy things happen and you're asking us to believe that the crazy thing that happened started when you got shot. >> yeah. >> when he pulled the trigger. >> yep. >> and then you must have taken the gun and fired two shots at him. >> yep. >> of course you hit a hole through his heart and one in his head which sound for all of the world when you hear that like those were targeted shots. is it possible you shot him and then decided you were going to shoot yourself? >> no, absolutely not. i have never been suicidal. >> the jury did hear the defense case of course just not robert's version of it. but it was enough for a verdict. >> robert dean hall guilty or not guilty of first-degree murder? not guilty. >> not guilty. hearts rose and fell. but then, not so fast. >> is robert dean hall guilty or not guilty of second-degree murder. guilty. >> guilty of murder. not premeditation per se but of an intent to kill and disregard for human life. rob hall looked like he had been punched in the stomach. tears sprang to his eyes. in march, hall was sentenced to 30 years in prison. he'll be eligible for parole in the year 2030 just past his 60th birthday. >> as we hit here now having been convicted of intentional murder, you're still not taking responsibility for it as that. >> as murder, no. >> you're saying the architect of this tragedy is more emmett corrigan than you? >> absolutely. yes. >> and so you sitting in prison for the next god knows how many years are as much a victim as anybody else? >> it's devastating. i wish i had never gone there that night to get my wife. >> or if you went that somehow you might not have taken your gun along. >> i think that. i do the what if game on that. then i think what if he would have pounded my face into the cement and not stopped and then people would say why didn't he have his gun with him? >> and thus you encountered one of the elements of classic tragedy. the thing you buy to protect yourself was the thing you used to destroy yourself. >> yep. >> another thing to contemplate in your jail cell late at night. >> yeah. >> he also thinks about his two daughters whose lives, graduations, triumphs, marriages, children he will never witness. they're living alone now, these two girls forced to fend for themselves at the ages of 18 and 14 because of a final twist to this story of betrayal and retribution. rob's wife, kandi incredibly is now in prison herself. because of the affair? no. she pleaded guilty to charges of grand theft for embezzling some $30,000 from the attorney for whom she worked before emmett corrigan lured her away. her sentence, 14 years but she could be released on a special diversion program in a matter of weeks. before she went to prison, she talked to us about regret. >> i had a lot of guilt still in me. a lot. it has to do with my kids and his kids and it makes me sick how i could do something like that. i am the responsible one and it's something i don't know if they're ever going to be able to get through that. hopefully one day i can prove to them that it was just a mistake. >> of course, proving to five fatherless children and a widow named ashley that it was just a mistake might be a little more difficult. >> i think there's thousands of people in this country that come those crossroads and don't know what to do but i think if i could tell them anything it would be put your family first. i guess i would like to say to rob. rob had five kids. couldn't this have been something you pictured as you held up the gun and targeted it at his head and his heart? >> once am meridian, idaho, were two happy, successful families. wasn't quite enough for some of them and the wreckage is forever. >> that's all for now. i'm lester holt. thanks for joining us. this sunday, are we ramping up for war in syria?
