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 ada county sheriffs office, locating vehicle locators inside squad cars. >> he loved every minute of his job. >> and as if it was a sign this is where they belonged, candy's career as a paralegal took off, too. she was a natural. could and did sell her houses and skills to anybody who walked in the door. >> it didn't hurt that she was pretty. >> no, it didn't. and her co-workers idolized candy. you became close? >> oh, we became very close. she was like a mother to me. >> yes, 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? >> yeah, 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. and 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?

>> yes. dearly. >> and wanted the marriage to continue in spite of the affair? >> yes, she did. she didn't want to believe in her head that he found something in this woman that wasn't in candy. >> well, 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. >> c'mon, no, he wanted to keep going on with the affair. that's what he wanted? >> i for sure told him to stop. >> stop right now or i'll stamp my foot and hold my breath. and he kept doing it? >> it was my fault. he had a void because of me. that's what i was thinking. >> what do you think the void might have been? >> i just 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 emmett corrigan. >> my friend, she said, emmett you got to meet candy. she's just as passionate and aggressive as you are, she would be great for you. >> and something suddenly lifted in candy hall. by the time those words had left her friend's mouth, candy knew, she just knew. >> candy hall has a decision to make a choice that would have consequences she never imagined, deadly ones. coming up. >> three unfaithful spouses and their lies are piling up. >> i could hear everything he we're saying because the baby monitor was on. the hard part then was that not a word he said was true. >> when dateline continues. t n a word he said was true. >> when dateline continues. arexvy does not protect everyone and is not for those with severe allergic reactions to its ingredients. those with weakened immune systems may have a lower response to the vaccine. the most common side effects are injection site pain, fatigue, muscle pain, headache, and joint pain. i chose arexvy. rsv?

>> yeah, pretty low. >> such problems. and then there was him. emmett corrigan fixed everything. he was handsome. he thought she was gorgeous. of course, he hired her right away for his new law office. you know what came next. soon there were racy e-mails, spicy text messages. >> i would like to be put on that pedestal. emmett made me feel that way. it was pretty much an ego boost for me. >> she really wasn't trying to get back to her husband, said candy, at least not consciously. >> i was thinking about me, only me, you know what it made me feel good, it made me feel like i was on top of the world. >> sitting here now is candy still only thinking only of candy? perhaps, as you hear the rest of this story, you can be the judge of that. anyway, back then, there were a few hitches in candy's new found fantasy life. emmett corrigan was also married, and lived in this quiet cul-de-sac with this woman, his wife, ashlee. >> he was just a guy that everybody wanted to be around. >> enthusiastic, full of energy? >> sometimes too much energy. but that's kind of one of the things i loved about him. >> just like candy and rob, ashlee and emmett met in a gym. there's was in college in utah 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 and -- >> you know what, 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 just as much as i love being a mom. >> in the winter they went skiing, sledding. in the summer they camped, swam at the lake they so loved. they made memories. ashlee 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 2010 and made the fateful decision to hire a paralegal, candy hall. not that he had any idea he was sealing his fate, of course, any more than wife ashlee understood his motivations. >> did you suspect she was involved with him? >> with emmett? >> why. >> the way he described her was an older woman who he looked up to in a motherly way. he said, she believes in me, she thinks i'm going to be a great law enforcement you saw her as an older woman. >> she was almost 40, i was 28. i never felt it was a competition i guess. >> that's for the many reasons that plainly escape those that get smacked on the hot stove of desire, themselves. emmett and candy thought otherwise. oh, they tried to keep their hand off each other for a little while said their co- workers, but if they believed they were hiding their obvious infatuation, their suddenly messy hair, hastily rearranged clothes, they were only fooling themselves. >> i noticed a significant change in her attitude went from being depressed about what rob had done to happy, you know. >> a spring in her step again? >> oh, yeah. >> such timing. now that rob seemed to fix their marriage. honesty took a holiday. >> i was living a lie, being in an affair is living one big lie. you lie about everything. >> yes. and she lied to herself, too. you were thinking of you and he together striding across the bow of the titanic. it's going to be it for you forever? >> yes. >> then one night ago a couple months ago the affair ticks toward their deadly conclusion. around bed time, candy received a text from emmett and couldn't hide it. >> the text popped up and rob read it and it said, i wish i was there with you tonight. >> what did he say? >> he was angry, candy, what is this? and i said, i don't know. so he calls emmett. rob goes 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 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 a good looking guy. he's an attorney, you make him a lot of money. what good am i? and he was just devastated. >> now you got yourself a pretty complicated life at this stage? >> yeah. >> of course, by february of 2011, emmett's life was complicated, too, ashlee 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 him if he lived with us anymore and we were in the bedroom, he's like, what's that all about? i was like, well, we miss you. and he just, he just kind of yelled and screamed and then left. >> ashlee thought maybe it was her fault. she went to marriage counseling. emmett refused to go. >> i felt really pushed away, 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 with 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 it 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 called 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 was, he just turned 4, was screaming one night for probably two hours, my dad's going to die, my dad's going to die and i just held him. i tried calling him, but he never answered his phone and it was a very strange weekend. >> strange? strange is not a big enough word to describe what was about to happen. >> coming up -- >> a secret meeting at walgreens and something will go horribly wrong. >> i go, "no, you are not doing this." he's like, "oh, we are doing this." >> when "dateline" continues. ." >> when "dateline" continues. it does not prevent covid-19. my symptoms are mild now, but i'm not risking it. if it's covid, paxlovid. paxlovid must be taken within the first five days of symptoms, and helps stop the virus from multiplying in your body. taking paxlovid with certain medicines can lead to serious or life-threatening side effects or affect how it or other medicines work, including hormonal birth control. it's critical to tell your doctor about all the medicines you take because certain tests or changes in their dosage may be needed. tell your doctor if you have kidney or liver problems, hiv-1, are or plan to become pregnant, or breastfeed. don't take paxlovid if you're allergic to nirmatrelvir, ritonavir, or any of its ingredients. serious side effects can include allergic reactions, some severe like anaphylaxis, and liver problems. these are not all the possible side effects so talk to your doctor. if it's covid, paxlovid. ask your doctor today.

>> i know we were probably coming down to the wire. >> you're having the unfair fights married couples have all the time. they betray each other with abandon and wonder why it doesn't work out? >> yeah. the thing i never wanted to face was the hurt that 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 -- >> well, now you can only look back and wish it had turned out that way. >> right. >> around the same time across town, about two miles away, ashlee corrigan had made a mistake and told her husband emmett that in her desperate state of worry, she had asked her family member to the pray for them. >> he said your family? i hate your family. i can beat your brother up and kill all of you. i grabbed his face and said you know what, i love you, i'm not going anywhere. i don't care what it is, just tell me what's happening. i don't know, i felt like that was the last chance and he didn't take it. he didn't open up about anything. >> at night, though, a trusted family member who had agreed to 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 this person. she says i'm the worst father ever. just things that i know i had 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. i said, oh, okay. do i get a turn? he says i don't care what you do, but you're not using my phone. and 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, no, i'm leaving. >> you must have felt like your life was falling apart and you didn't know what to do? >> i kind of like maybe this is the grand finale. >> but he needed a wake-up call? >> he needed a wake-up call. >> careful what you wish for. getting very dark. maybe he shouldn't move out, maybe they should try to fix their marriage, 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'm going to go to walgreens through the drive through. i'll be right back. >> here's candy's explanation for the way the meeting with her lover was arranged. >> as i was pulling out the back of my driveway, emmett texted me, hey, what are you doing? >> i said i'm going to walgreens. he goes, i was just there, hey, meet me there. >> then what happened next? you can watch it yourself right here on surveillance tape. >> i go to walgreens, through the drive through. i pull around, he pulls up. i get in his truck. we go to fred meyer. >> there they are again getting gas as fred meyer when emmett opened the rear door. >> he pulls out all these prescription bottles. i said what are you taking? he said if you don't want to grow a don't take it. and then he got back in the truck and we drove off. >> from there they pulled into a seclude spot and had sex under a street light. that's where they were, tangled up in each other, when candy phone rang. her daughter coming home from a date, had seen her car in that parking lot. she said, "mom, why is your car at walgreens? i called dad." i go, "oh, all right. okay. i'll be home in a minute." >> too late because now the wind was up. rob the unfaithful husband had to know, now he was the aggrieved spouse and sure enough as candy talked to her daughter. here he was in his pickup truck to come to walgreens to look for his wife. >> phone call from rob. he goes, "are you with emmett? " and i go, i took a deep breath and said, "yep, i am." emmett looks over at me, he takes the phone away from me and he goes, "yeah, what's up, chief?

". >> frantically, candy's fingers somehow found the numbers 911. >> oh my good, oh my good, robert, robert, 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 candy 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 a judge will soon see. they can certainly be amended. what we know for sure is she rushed to the prostrate body of one of those two men. >> i gave him kiss on his cheek and i'll never forget ever but he took that last, you know, deep and it was very surreal, it was just turning grey here, 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? the tragic lapse in judgment, a thoughtless but unintended crime of passion or was it murder in the first degree? >> when "dateline" continues.

" >> and the night of the shooting, prosecutors played those surveillance tapes from walgreens, showing rob arriving 17 minutes, walking through the aisles, looking for candy. all the while with a pistol, not the one he usually carried, but the one candy gave him, tucked in his pocket. then the jury saw emmett and candy arrive in the parking lot and 8 minutes later heard candy's 911 call after shots were fired. >> oh my good! oh my god! robert, robert, robert, robert! >> what happened? the prosecutor said the sequence 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 back up by forensics the shots were fired by close range, two or three feet. a heavy concentration of gunshot residue on only robert hall's hand and one dna on the trigger guard. >> the dna matched that of mr. hall. >> i think that robert 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 candy 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 neat and 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 who was out of control, emmett who kept amphetamines and steroids in his pickup truck. drugs with serious side effects said experts. >> he had hyperability, as well as impulsiveness and an explosive temper. >> what really happened? rob didn't testify. a doctor backed his claim because of his head wound he simply couldn't remember. so the defense offered a theory that emmett started the fire. then the gun fell on the ground. emmett grabbed it, shot rob in the pause rob grabbed ahold and fired back in self defence. and 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? >> candy hall. >> candy, who repeated the story on the stand, that she told us of emmett pushing rob. emmett becoming enraged of hearing the two men scuffle as 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 you did not see or hear a physical altercation, isn't that right? >> i don't know. i don't remember. >> in fact, candy changed her story about so many things, all helpful to rob's case. >> i'm trying to clarify that your story has changed after speaking with your husband? >> things were remembered after talking to my husband. >> in fact, later, the judge made a comment outside the jury's presence. >> he said in all of his 30- some years on the bench he'd never seen a witness so thoroughly discredited. >> but before she left the witness stand, candy 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've never stopped loving him. you just don't stop loving someone. >> and watching it all, emmett's wife, ashlee. >> you watched as candy testified and what was that like? >> it was 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 had spoken of this, but first, it's up to the jury, to determine the wages of sen. coming up -- a husband with a stunning story to tell. >> last thing i remember it was the gunpointed at my head. when dateline continues. when dateline continues. with dupixent, the number one prescribed biologic by dermatologists and allergists, you can stay ahead of your eczema. it helps block a key source of inflammation inside the body that can cause eczema to help heal your skin from within. many adults saw 90% clearer skin. some even achieved long—lasting clearer skin and fast itch relief after first dose. serious allergic reactions can occur that can be severe. tell your doctor about new or worsening eye problems such as eye pain or vision changes including blurred vision, joint aches and pain, or a parasitic infection. don't change or stop asthma medicines without talking to your doctor. ♪♪ show off to the world. ask your eczema specialist about dupixent.

>> yeah. >> and then you must have taken the gun and fired two shots at him? >> yeah. >> of course, he had holes through his heart and one in his head, which sound for all 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. >> is 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. >> guilty. not premeditation per se but of an attempt to kill and a disregard for human life. rob hall looked look he had been punched in the stomach. tears sprang to his eyes. hall was sentenced to 30 years in prison. he will be eligible for parole in the year 2028, just before his 60th birthday. so as we sit 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 like not taken your gun along? >> i think that. i do the what if game on that. and i think you know what if he would have pounded my face into the cement and not stopped? and then people would say, well, why didn't he have his gun with him? >> and, thus, you would encounter one of the elements of tragic almost. the thing you buy to protect yourself you use to destroy yourself. >> yeah. >> another thing to contemplate in your jail cell late at night? >> yeah. >> he also thinks about his two daughters, whose lives, their graduations, triumphs, marriages, children, he will never witness. two girls, who at the ages of 18 and 14 back then, suddenly found themselves left without either parent at home. because of a final twist to this story of the trail of retribution. rob's wife candy was sent to prison herself because of the killing? no, she pleaded guilty to charges of grand theft for embezzling some $30,000 from the attorney for whom she worked before emmett corrigan. she served 18 months for that. she's on parole now. before she went to prison she talked to us about regret. >> i have a lot of guilt still in me. a lot. and 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 that i don't know are they ever be able to get through that? i mean, hopefully, one day i can prove to them that it was just a mistake. >> in the years since, ashlee has remarried and has become an author/blogger and speaker with a message to stand strong and faithful. >> i think there's thousands of people in this country that come to those crossroads and don't know what to do. but, i think if i can tell them anything, it would be, put your family first. i guess i would like to say to rob, rob, he 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 in meridian, idaho, were two happy, successful families. it wasn't quite enough for some of them and the wreckage is forever. >> that's all for this edition of "dateline.
