he said, i don't care what you do but you're not using my phone. emmitt said, i'm going to run to walgreens and i'll be right back. i put the phone down, i literally was like, emmitt, please do not leave. and he said, no, i'm leaving. >> you must have felt like your life was flying apart and you don't know what to do. >> i kind of felt like, okay, maybe this is the grand finale. >> that he needed a wakeup call. >> he did, he needed a wakeup call. >> careful what you wish for. getting late now, very dark. over at the hall house, candy had been talking to her husband, rob. 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 what? >> i said, i need to go to walgreens, i'm going to go through the drive-thru, 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 of the

back of my driveway, emmitt texted me, hey, what are you doing? i said, i'm going to walgreens. he goes, i was just there, hey, 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-thru. and i pull around and i park my car. then he pulls up, and i get in his truck, and we go to fred meyer. >> there they are again getting gas at fred meyer when emmitt opened the truck's rear door. >> he pulls out all these prescription bottles. and 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 candy and emmitt pulled into a secluded spot and had sex under a street light. that's where they were, tangled up in each other, when candy's 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, 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. as candy talked to her daughter, here he was come to walgreens to look for his wife. >> phone call from rob. are you with emmitt? and i go -- took a deep breath and i said, yep, i am. emmitt looks over at me. he takes the phone away from me and he goes, yeah, what's up, chief? and 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.

for months andy hall and emmitt corrigan had been having a steamy affair. but this late-night tryst would be their last. they were in emmitt's pickup truck when candy's husband rob called and her young lover grabbed the phone. now emmitt was heading to a parking lot to confront rob, and soon one of them would be dead. once again here's keith morrison with "deadly desire." >> 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 in these store surveillance videos, rob parked his pickup truck, went through the front door, roamed the beauty ask cosmetic aisles. he was looking for his wife candy, who of course was also in a pickup truck with her lover, emmitt. here you can see rob leaving the store, looking at candy's parked bmw, then strangely getting back

into his own pickup truck, pulling out, then reparking it on the over side of candy's car. curiously his door just out of range of the store's surveillance camera. this is when he made that phone call, the one in which candy confessed she'd been with her boss, emmitt corrigan, and he said to rob, what's up, chief? here's emmitt's car speeding through the parking lot. still time to stop this if wiser heads had been in charge. >> i see rob in his truck. he has this look on his face like, oh man. and i get out of the truck. then emmitt gets out. then rob gets out. 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. might have 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 emmitt said, rob, she doesn't want to be with you anymore, okay? she's done. really, rob, what did you make last year, $40,000? candy, what did we make last week, $27,000 last week in one week, rob, that's how much i make. you don't make anything. >> nasty, of course. arrogant. like a thoughtless young buck who 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? and at that moment emmitt's eyes got huge and he pushed himself off of his truck and went over to rob and pushed rob very 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, and rob, we got to go. and as i was walking to my car, another car came by and i had to stop. and at that point i hear pop, pop pop. i didn't know what it was. i didn't know if that car just backfireded. i had no idea. and i stopped and went -- like, what was that? and all's i see in my peripheral vision right here is rob cover ed. >> candy's fingers somehow found the numbers 911. the pistol went flying. 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 a police department and lawyers and a judge will soon see, they can certainly be emmended. what we know for sure is she rushed to the prostraight body of one of those two men. >> i gave him a kiss on his cheek. and i'll never forget, ever, but he took that last deep -- is very surreal, just turning gray, to 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 -- 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?

ashley corrigan did not go to sleep after her angry husband announced he was going to the walgreens drugstore in her meridian, idaho. so she was up at 1:00 in the morning when the police came. emmitt was dead, they told her.

killed by her lover's husband. and areally entered a twilight zone of her own. >> it was like the ultimate humiliation. it was, not only is your husband gone, but you know that marriage you were trying to save? here's all the answers of why it was going wrong. now you don't have a marriage to save anymore. it was just like every emotion possible. i went through a divorce and a death all in one second. >> bizarre. >> and then i had to get prepared to tell my kids. and what story do you tell little kids? well, there's been an accident and your daddy's spirit's left his body so he's not going to be on the 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, police said, of a botched suicide attempt.

after rob put two bullets from his semiautomatic pistol into emmitt corrigan, one in his heart, one in his head. and over at the meridian police station, candy hall, her 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. >> yes. >> as a jezebel, as a woman who's at the center of a tawdry 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's looking at me, everybody knows who i am. >> everybody knows what i did. >> yes. but it did happen. and i own it.

>> here's something else that happened. although on the night of the shooting candy 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 jessica larello and jason spillman, who prosecuted the case. >> this is a case of a manhunting down his wife's paramour and waiting for 17 minutes to have the opportunity to kill him. >> 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 emmitt's law office repeatedly to berate candy so loudly that others

heard it all. >> statements such as "you're a whore," "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 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 emmitt and candy arrive in the parking lot. eight minutes later, heard candy's 911 call after shots were fired. 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 emmitt 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 emmitt corrigan, that he took a loaded gun and rob decided that was his opportunity to get his candy back, by killing emmitt. >> why did he talk to emmitt 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 emmitt corrigan. >> a neat and tidy theory,

agreed the defense. but completely wrong. >> this fight started by emmitt corrigan. >> rob was a nice guy, said the defense, and it was emmitt who was out of control. emmitt who kept amphetamines and steroids in his pickup truck, drugs with serious side effects, said a defense expert. >> he was hyperability as well as explosiveness, temper. >> what really happened? rob didn't testify, a doctor backed his claims that because of a head wound he simply couldn't remember. so the defense offered a theory that emmitt started the fight, then the gun fell on the ground, emmitt grabbed it, shot rob, then during the pause rob got hold of the gun and 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? >> candy hall. >> candy, who repeated the story on the stand that she told to us of emmitt pushing rob, emmitt 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 that 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 stories changed after speaking with your husband. >> things were remembered after talking to my husband. >> okay. >> 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.

>> before she left the witness stand, candy expressed her love and sorrow for the man she'd 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, emmitt's wife ashley. you watched as candy testified. what was that like? >> it's hard to hear her stand up there and tell her husband how sorry she was, 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 -- a husband with a stunning story to tell.

anything at all, we have a small advantage over the jury. hall did to the tenot testify, 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 emmitt corrigan -- i didn't bring a gun there to gun down emmitt corrigan. >> hall's version? that despite what you've heard, he did not even know for sure that emmitt was having an affair with candy, that in the parking lot emmitt 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, grabbed my gun, and we just struggled over it. last thing i remember was the

gun pointed at my head. and the feeling of being hit upside the head with a baseball bat. and i remember seeing everything black and gray. and that's all i remember. till 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. >> and he pulled the trigger? >> yep. >> 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've 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 rob bent dean hat guilty or not guilty of second degree murder? guilty. >> guilty not of premeditation but attempt to kill. robert hall looked like he'd been punched in the stomach. tears sprang to his eyes. sentenced to 30 years in prison. he'll be eligible for parole in the year 2028, just before his 60th birthday. >> 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 emmitt 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'd not taken your gun along? >> i think that i'd do the what if game on that. 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 encounter one of the elements of classic tragedy. the thing you buy to protect yourself is the thing you use to destroy yourself. >> yeah. >> another thing to contemplate in your jail cell late at night. >> yeah.

do something like that. i'm the responsible one, and it's something that i don't know whether i'm ever going to 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 ashley 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 could tell them anybody, 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.
