what is your first interaction with brett parker? >> he was sort of heavy breathing. at one point in time he lays down on his back as if he is suffering, almost in pain. >> inside stand smith walked into a gruesome scene. the body of brett's wife tammy was in the bathroom. and lying nearby was a man named bryan capnerhurst, dead in an alcove not far from the safe where brett kept his money. >> it appeared tammy parker was sitting at the desk in the office area. and that the shooter shot her from the back. half of her torso was inside the bathroom, half was in the office area. so she definitely try to flee. as far as bryan capnerhurst, he was found slumped over on his right side. he was shot multiple times in the face, in the chest. in the side, the legs, the foot. >> the investigators were surprised when bright told them bryan capnerhurst, the man he

had shot, was a family friend and frequent visitor to the house. in fact, brett said he was in the bathroom when bryan arrived for a meeting and he told him to just go upstairs and wait. suddenly, brett heard shots. >> he ran upstairs and was greeted at the top of the stairs by bryan capnerhurst, toting a gun on him. and ordered him to the safe which was in the alcove area of the active. as he walked by the office he saw his wife legs, and he surmised that she was shot. he was taken to this alcove area and on the way he realized, or recalled he had a gun. and in the safe area. he said he made a decision at he knelt at gunpoint to grab the gun and try to get to capnerhurst before capnerhurst shot him, basically. >> so he turned around and caught bryan off guard? >> that's the way he explained. it >> by shooting? and >> right. >> he said he realize his wife died was dead or dying and then he went and called 9-1-1.

didn't even think. about >> and brett was not the sopranos baker lake style type of bookie was bright a gentle bookie? >> oh, very, very. everybody says that he delivered his money. brett was a good bookie. >> brett also told investigators that bryan capnerhurst, the man he had just shot and killed, was in the bookie business to. as a matter of fact, he worked for brett. bryan was also an unlikely bookie. a former high school athlete, he was a family man who worked for a county recreational commission and coached kids sports teams. tammy had spoken kindly of him. i >> think she thought he was a nice guy. she must have thought a lot because he was in her home. with her children around. and tammy was very protective of her children. >> and i think he trusted? her >> right. exactly. tammy had always looked out for him. getting an extra large for him, taking care of him. >> but investigators found out there had been a problem in that bookie business, and it

all boiled down to money. brett told bryan a good chunk of the profits. $20,000. and he had been slow to pay up. >> it bryan was going to go for their basically until brett i have had enough of this, you only money. >> smith learned that bryan capnerhurst had money problems. so it looked like he went to the parker's to demand money he was owed and take whatever else was in the safe. tammy had simply been in the wrong place at the wrong time. what do you miss most about tammy? >> her laugh. just her being. she would always call. she always make sure we had our girls nights out. we haven't done that since she was killed. >> it was all so sad. the partners with their children had just returned from a family cruise, tanned and smiling. a relative on that cruise told brett's and sandra hunter, it had been a wonderful trip. >> she said that that was the

happiest she had seen brett and tammy. >> and now brett's friend saw a man in pain after losing his wife. >> he just breakdown crying. and he would cry all the. time >> as for shooting bryan, -- believed his friend had to do what he had to do. he >> didn't have a choice. it was either him or bryan, that's the way he told us, over and over. you know? >> to those grieving for tammy, it seemed that at least there had been some terrible justice for bryan. >> people that loved tammy so much, you know, you couldn't help but feel that he may be -- people thought maybe he got what he deserve. >> investigators told reporters that tragic deaths were the result of a robbery gone bad. it seemed like a cut and dry case. but things aren't always what they seem. >> was brett parker the loving husband he appeared to be? investigators were about to uncover a secret. coming up -- >> there were a series of text

[ screams ] what the frittata? i'm sending you undercover. is this some kind of a ninja boy band? whah! -huh. oh my gosh. oh my gosh! >> police had announced the double murder in ascot estates was a robbery gone very wrong. the unlikely intruder, that parker's family friend bryan capnerhurst. brett told the investigators

that his friend bryan had shot his wife hatami in a botched robbery attempt. then brett, in fear for his own life, killed his friend. it looked like self-defense. but sheriff leon lott knew they couldn't close the case without thoroughly checking out brett's story. >> there were three people there. and two of them were dead. so we had to light on him to explain to us what happened. so we listened to everything that he was saying and then we would go back and check it. >> investigators went over brett's account, starting with the moment bryan entered the house. before long, something unusual came to their attention. brett told police he was sitting on the downstairs toilet when he heard the shots ring out. but what if the female crime scene investigators notice this. the toilet seat was up. >> our csi lieutenant is a female, and she made mention of that because it particularly bothered her. >> it takes one to look at this notice that. >> right. >> as they poured over crime

scene photos, another small but important detail jumped out. bryan's jim bag with ammunition and an empty magazine clip big visible. >> the unusual thing about it, those items were found on top of the clothing of the items in the. back >> unusual because of what they noticed on the home security video that captured bryan arriving at the house. >> if you look at the video, when bryan notch along lee through that bag over his shoulder, those items would've gone to the lowest point in the bag. so it is almost like those items had been policed there. >> and there was more that didn't seem to quite add up. investigators took a hard look at the timeline of the crime as brett described it. that home security video showed bryan arriving at brett's at 12 to routine 1 pm. brett called 9-1-1 had to report having shot bryan at 12:42. >> what happened? who shot your wife? >> a friend of mine. we bryan. >> police believe the confrontation should have only taken a couple of minutes. so why, they wondered, had

brett taken nine more minutes to call 9-1-1? police were also curious why with his wife shot inside, brett had come outside to make that call. >> if it were me, i would've been at the side of my wife. trying to administer cpr, first aid to my wife. and he didn't appear to have any blood on him. >> was that strange that he didn't have blood on him? >> it was. >> investigators picked through every detail in brett's account and found that while he had been upfront about his illegal bookie business, he was an upfront about everything. >> we recovered certain things from brett. like when we asked if he was involved in a fulfill trust affairs he told us. no within 24 hours, he told us we found out that wasn't true. there was a series of text messages of a sexual nature, indicative of an affair. >> they started looking looking at the evidence versus what he said. and over a period of time, it just kept getting more red forelegs coming up. >> tammy's best friend angela

leon didn't know anything about the investigation. that she had a gut feeling something wasn't right. she called up the sheriff's department to say she thought brett was lying. >> i reached out to them and wanted to make sure they knew that there were people that had a different side of the story. >> brett continue to insist it was self-defense. but within a week of the shooting, he had gotten a lawyer, david fedor. the sheriff's told us he thought it was a little odd that brett retained a defense attorney so early when he was claiming he was a victim. >> anybody that is in a situation like that that doesn't retain an attorney immediately need psychiatric help. >> his attorney said brett was no killer. he was just defending himself after bryan showed up to steal his. money >> capnerhurst went over there specifically to rob the people. tammy was there. he shot her first. and we assumed he was going to shoot brett. and brett got the drop on him instead.

>> what motive could he have to shoot her? >> the motive he would have to shoot her was getting the money out of the safe and having no witnesses. >> why carry out a burglary when you know the wife is home? >> you're gonna guess is as good as mine. i >> think some people just find that hard to believe. >> sure they do. people find it hard to believe that airplanes fly, but it happens. >> brett parker met directly with sheriff leon lott. he even invited the sheriff to the house to show him the crime scene. >> he wanted to walk me through the house to demonstrate what had happened. and after that meeting we sat at the kitchen table and and at that point was the first time i told him i just didn't believe him. >> the sheriff was now convinced that brett was no victim. he was the mastermind of a cruel and a highly unusual plot to kill his wife and frame a friend. >> he'd gotten away with his gambling for so many years. what else was he going to get away with? >> three months after the murders, there was startling news. >> the richland county

sheriff's department says parker is lying. >> brett parker was charged with two murders. why do you think it took so long? >> because they didn't have a case, is what i find. >> as the case headed to trial, there were no witnesses, no video of the crime and little forensic evidence pointing to either brett or bryan, as the real killer. >> it was a high profile case. two killings in a small town. they wanted to make the most of it. >> coming up -- the trial opens with a bombshell. not about him, but about her. >> ways your was your relationship with her more intimate? >> when dateline continues. dateline continues get pataday once daily relief extra strength. the first and only 24-hour eye allergy itch relief drop now without a prescription. a single drop of pataday once daily relief extra strength works on the cells that make your eyes itch...fast.

south carolina, was reeling from the news that brett parker, the only survivor of a tragedy which left two people dead, had himself been charged as the cold blooded killer who masterminded the whole plan. brett on's family and friends believed he was a man wrongly accused. >> we just wanted him to know that he was into nelson. every time he said i did not do it. >> even tammy's close friend, former bandmate woody woodward, had a hard time believing brett was guilty. you had no reason to doubt brett it sounds like? >> i believed him. i actually called him as a character witness and i told him i would be glad to. because i did not see him doing this. >> when the trial began in may, it was a courtroom divided. on one side, brett's family and friends, including his and tammy's teenage daughter. on the other side, friends and family of tammy and brian sat

together. they wore blue, tammy's favorite color. as a sure of unity against the man they believe murdered both victims. >> there were shots fired in the home. >> in her opening statement, the prosecutor minced no words. brett parker had committed a terrible crime that elaborately covered it up. >> as you listen to the details of this case, you will be firmly convinced that it was brett parker who not only had the motive bag actually did kill tammy parker. and then bryan listen capnerhurst. >> prosecutors wanted the jury to know that the parker marriage wasn't what it seemed. brett had strayed. once with an out of town woman and several times with a local bank teller. lindsay mullins testified that they met, they texted, and that he shared some confidence is about his marriage. >> he said that he slept

upstairs and she slept downstairs. >> but the partners had more problems than just brett's affairs. they called ben staples to the sand, a parker family friend. >> what did you know about the march? >> well, as the years went by, she was unhappy. she had conversations, we had conversations. brett did not believe in god, or going to church. that was important to. her >> to them, that revealed another bit of evidence about the parker's shaky marriage. this one a bombshell. >> was your relationship -- >> yes. at >> approximately how urkullu was that. >> about three years ago. >> and did that and? >> it did. it did not end our friendship. we remained best friends until her murder. >> the public admission of the affair was a total shock. even to those closest to tammy. >> so this was a secret she can't from her girlfriends? >> she did. we always felt like ben probably loved tammy. because how could you not love

tammy. and we didn't know them that well. so, we didn't think that had happened. >> we lanny gunther, an old friend and former bookie, testified that four months before the murders brett was talking about separation. >> my advice to him, if he being that it was coming up on the holidays. for him to try to go home and work out with tammy and at least get through the holidays for the kids state. and then after the first of the year, for them to try to get back together. and if separation was their option them, then so be it. >> a bad marriage is one thing, murder is another. so prosecutors turned to a different motive. money. unbeknownst to tammy, brett was in deep debt. he had made the biggest mistake he bookie can make, he gambled himself. and brett was it too good at. it >> gunther told an investigator bright obtain big money. i just told him >> that his own account. the hundred thousand, 1000. >> and this was not the first

time brett scrambling have been a serious issue. >> he was caught before it is a serious amount of debt. his father bailed him out, about $100,000. >> the state try to convince the jury that killing tammy had been brett's we out of a shaky marriage and his gambling debt. tammy had taking out a life insurance policy. >> 360,000 was the ultimate amount. >> who was a beneficiary on? that >> bright. >> tommy also had close to $200,000 in a four one key. combined with the insurance, nearly 1.1 million all left to brett. what kind of man sets up his friend to take the fall for murdering his wife, and then he murders the friend and leaves him with a legacy of that he murdered somebody. >> he wanted to perpetuate this lifestyle. he wanted to continue to gamble. he wanted to enjoy the girlfriends. and tammy was a hindrance. he felt like this is was his we. out >> in court, the ugly accusations seem to get to brett, as the medical examiner

testified about families fatal injuries. brett said he fell ill and was rushed to the hospital. brett was back however the next day, to hear the prosecution present evidence it said proved he planned the murders and framed his friend and then covered it up. here's how they said he did it. first he shot and killed his wife in that upstairs office. then at 12:25 pm, brats ohm whom security camera catches someone peering through the blinds. prosecutors believe it was brett waiting for bryan to arrive for a meeting brett himself had arrange. gunshot residue was found on those blinds, proof the state said, that brett had already fired a gun before bryan even arrived. >> at 12:25, who is that peeking out of the blinds? that was somebody, in our opinion, who had just done this heinous thing. and was nervously awaiting his fall guy to show up. >> after killing bryan, his

fall guy, prosecutors said brett stage the crime scene and planted that gym bag and ammunition. >> i guess the idea that was supposed to be some kind of murder by. >> and place the gun he used to kill his wife in bryan's hand. there is no way bryan brought that down to bret's house, affront has defied. >> did you know whether bryan had a gun? >> no, but heck no he did not have again. brian was scared of guns. there is no way on this earth that bryan capnerhurst had a pistol. none. zero. it did not happen. >> and there was something else -- >> that gunshot to the four arm >> bryan had suffered a major gunshot wound to his arm. but he was still clutching the gun as he lay down on the floor. a medical examiner testified it's unlikely the gun would have stayed in his hand. >> in my medical opinion, based on the shots to the arm, to the

four arm and falling over, i believe that the gun fell out of his hand. >> the gun had been placed in his hand. >> the prosecution had made its case. now it was time for the defense to fight back. >> they had no proof whatsoever that he shot his wife. it was completely circumstantial. >> the defense was about to tell the jury that bryan capnerhurst, not brett brett parker was the real villain. >> coming up -- brits team produces a powerful witness to back up his story. his teenage daughter. >> i was there and i remember -- >> when dateline continues. tinues e created a brand-new way for you to sell your car. whether it's a year old or a few years old. we wanna buy your car. so go to carvana and enter your license plate answer a few questions. and our techno wizardry calculates your car's value and gives you a real offer in seconds.

to set this thing up. >> would it take a genius though to concoct a plan like that? >> i think i'm fairly bright and i'd be damned if i could've thought about that. >> if he fired that handgun -- >> in court, brett parker's attorney said brian cap near hearst was a desperate man with far more motive for murder. >> a man that was at the end of his rope. who had a desire for money, and a plan for violence. and the evidence in this case have been proven. >> still, the defense thought it had an uphill battle, he knew it didn't help his case that his client was an unfaithful husband and gambler. >> he showed he was a bad man because he gambled. he had an affair. they said that was another thing that showed he was a murderer. it was just ludicrous. >> from the start, he and co-counsel or wanted the jury to know, okay, sure, brett is a

gambler himself was deep in debt, but he wasn't debt to an old friend he'd known since he was 15. >> you weren't worried about that? >> i've never been worried about brett. >> if you had called you and said look i have a problem, you would've written the whole thing clean for him? >> yes. >> you've never put any pressure on him? >> no sir. >> and that life insurance policy the prosecution suggested was a smoking gun? the insurance agent testified brett wasn't all that interested in a policy on tammy. >> did you attempt to sell him insurance on his wife? >> yes. >> were you successful in selling him insurance on his wife? >> i was not. >> tammy had taken the insurance on her own, and instead of claiming a dime for himself, brett had already signed the insurance money over to his kids. >> did he tell you directly

objected. brett's attorney told us it was just a family habit to leave the toilet seat up to make things easier for their young son. >> he has a six-year-old child, every time the child comes in from school, he runs to the bathroom right away. brett and his wife always put the seat up. >> he hears shots fired in his house and he is going to think about putting the toilet seat up? >> it is a reaction if you do it every day. >> it was explainable behavior, the motive was flimsy said the defense. now it attacked the states forensic evidence. the defense use the amount of gunshot residue found on bret's hands to undermine the theory that bright had shot his wife with one gun, and his friend with another. arguing there just wasn't enough gun residue on his hands to have fired both weapons. >> if he fired both 9 mm and the 4:10 revolver, in combination, i would expects
