and that was just the start. a gun stashed in the dryer, a man's glove, but whose dna? and a woman with a whole lot to reveal. >> no, no, no, no, don't take it off. >> she talked her talk to me. >> do you realize that some of her secrets would be exposed? >> "mystery in mustang." but first, she was a well liked valedictorian at poplar high, and one summer night down by the river. >> i could hear all these girls saying get her, chasing her. dragged her. a horrible scream. >> some in town claim this was a murder by a gang of mean girls. but he's the one that's convicted, sent to prison. >> i did not kill kim nees, you have my promise. >> sentenced to 100 years. >> guilty as charged. not one moment. >> did he really commit this crime? that's a question that drew us to this case and drove us to investigate. >> a "dateline" piece where these witnesses have the courage to come forward. >> and just months ago, a dramatic new development, a whole new ending. >> it was the last thing we ever anticipated happening. >> i am lester holt, this is "dateline." we begin tonight with keith morrison and return to poplar river. >> there is a common misconception that momentous events occur in great cities, that justice is handed down true and pure from marble palaces. but what would lady justice say about the story you're going to see now, about a nobody in a nowhere town, a story that is, well, what would they say? >> this is crazy. how can you do this. >> i couldn't believe it. >> this is definitely a shock. >> yes. it is all of those things, shocking, unbelievable, crazy. and tied with an unbreakable chain to a summer's night in a poor forgotten back water more than 30 years ago. the town is poplar, montana, june 15th, 1979. summer was here. school was out. kim nees, 17, school valedictorian, national honor society graduate, was finally about to escape this town for college. around about midnight kim left her house to join the end of school party. it was the next morning when police found the family pickup at a well known party spot a half mile outside town. they followed a trail of blood from the truck down a rotted dirt track, 250 feet or so, to the poplar river, and there they found the battered body of kim nees. >> the term i used was overkill. >> dean mallom was undersheriff, later the sheriff in the investigation. >> there were 20 to 21 blows to kim's skull, which any of which could have caused her death. >> there was rage involved? >> there was a high level of rage, someone was very angry. >> at the crime scene, no shortage of evidence. blood everywhere, inside the cab of the pickup, fingerprints, more than two dozen, multiple footprints in and around the trail where kim's body was dragged to the river. and on the truck near the passenger door, a palm print in blood. the fbi lifted the print, said it would have to have been left by the killer. >> we worked very, very, very hard at determining whose that was. >> why kim nees? wasn't a robbery or sexual assault. people do talk. and around town the story was that this was call it a jealousy killing. kim was popular, attractive, class valedictorian. the boys loved her. and she was about to leave poplar behind for good. the story was that this was local kids, mostly girls, who beat her to death. so went the rumor. >> that was one of the, again if you will, the theories that folks around town had is that there may have been three or four of kim's peers that were involved with her death. >> bobby clincher heard the talk, she lived down the block from the knees family. >> what did you hear? >> her grandfather had told me all indications are that it was girls. >> though many of poplar's teens, boys and girls wound up on a list of potential suspects, including bobby's son barry who once dated kim's sister. >> did you question him harshly about it? >> uh-huh, he said repeatedly he didn't know anything about it. the only thing he knew is what he had heard, what he had been told. >> that's what all the kids told the police, too, and nothing happened. nobody was arrested. three years went by. then in january, 1983 sheriff mallon picked up the phone, found himself talking to a detective from way down south. >> he asked if i was aware of an individual by the name of barry beach, wanted to know if mr. beach was or had ever been a suspect in homicide in roosevelt county. >> barry was almost 21 by then. he had gone to louisiana to be with his father and stepmother. wasn't going well. in fact, his stepmother had him arrested for helping his step sister skip school. then told arriving police officers that barry was once questioned about the murder of kim nees in montana. well, it just so happened investigators in louisiana were scratching their heads over murders of three women in their county. so could beach be their killer? >> from talking to sheriff, the fact he was a viable suspect. >> so the detective that called the montana sheriff interrogated beach about the louisiana murders. what made you think he was the kind of guy would be your prime suspect? >> the fact that he was a suspect in a murder already. >> so the detective put barry in a little room here at the sheriff's office and groomed him. f -- grilled him for two days. after many hours of questioning, his answers about kim nees changed, according to jay vy anyway. >> we asked him were you responsible. this part of the interview, he kept saying i don't remember if i was or not. >> soon the detective was joined in his work by commander alfred calhoun, known as something of a closer. vy stepped out of the room while the commander worked on barry. >> alfred stepped out of the interview, said he wants to talk to you. when i walked in the room, barry was crying, and he admitted to killing kimberly nees. >> the mystery was solved. all the rumors about other suspects, including that group of girls, long whispered of in connection with the crime, were apparently wrong. vy allowed barry to call his mother back in montana. >> i said barry, why did you confess to something you didn't do? and he said well, they're going to come back to montana and help me prove i didn't do this. >> but in montana, helping barry beach was not on the menu. first degree murder was. barry pleaded not guilty, but when his trial began at the courthouse in glasgow, montana, the prosecutor came on very strong. >> i had a detailed confession that only the killer could have given. >> within a decade, mark roscoe would be elected montana's governor. in 1984, though, he prosecuted barry beach. >> he gave a very detailed confession that matched the things that were discovered at the crime scene. >> like what? well, beach described the shirt kim wore, the tire iron and crescent wrench used to kill her, how she was dragged out the driver's side of the pickup, on and on. when testimony was finished, the jury was back in just six hours. the verdict, guilty. and so in the spring of 1984, the story of the life of barry beach was apparently over. dead man walking, sentenced to 100 years, no parole. but of course, who are we fooling. the amazing story had really just begun. >> why would barry beach confess to a crime he says he didn't commit? if he's innocent as he claims, can he somehow prove it? when we come back, a closer look at the evidence, where it points, and where it doesn't. >> it's not barry beach's palm print. a new way to get a new device every year. no down payment, no upgrade fee, no activation fee, no financing fee. it's time to rethink how you get a new device. ♪ it'hurry in forthink petsmart hot summer buys!. save 50% on hundreds of items and save 25% on any top dog add-on package with a bath or groom purchase. this weekend only... ...at petsmart®.

>> when they gave me 100 years, they gave me 100 years to prove i didn't commit the crime that put me behind bars. >> didn't commit the crime? how could he claim such a thing, after all, he confessed. what more was there to say? well, actually quite a bit. weren't exactly a choir boy, were you? >> no, sir. i drove fast cars. i liked rock and roll. >> and you liked to party. >> every chance i got to be honest with you. >> and what really happened he said on the day of the murder in june, 1979 was this. he was drinking and smoking dope and swimming in the poplar river outside town. by the time he walked the mile back home, he said. >> i actually went straight to my bedroom, went to sleep. >> what time was this. >> somewhere between 5:00 and 6:00 in the evening. >> when kim nees was murdered, he said he was fast asleep. but even though his sister swore he was telling the truth, there was that confession. you said you killed that girl up in montana. >> yes, sir. i said that i killed kim nees. >> and that's when the story enters the twilight zone. barry beach says he believed he was about to be released from prison, the minor charges called in by his stepmother about to be dropped, when suddenly he found himself in an interrogation room answering questions about murder. those detectives seemed to think he had committed the three unsolved louisiana murders. the murders they were trying so very hard to solve. >> next thing i know, they started showing me pictures of dead bodies and told me remember doing this, and i would say -- i was telling them i didn't do it, i didn't kill anyone. >> but as the day wore on and his anxiety, fatigue, confusion grew, the door opened, and in walked commander alfred calhoun. >> he promised me that he would personally see me fry in the louisiana electric chair. >> what were you feeling in the middle of all this? >> i was scared to death, keith, but i knew he would execute me if given the chance. >> then said barry the talk turned to the murder in montana, the murder of kim nees. >> well, it started off that they asked me to speculate how it happened, then i was asked to give a hypothetical story using myself as the perpetrator. >> then he said he heard the detectives tell him if he just went ahead and gave them a confession, they'd help him prove his innocence later when they got back to montana. >> i don't deny that the confession took place. i don't remember all the details of it. >> barry, come on. i really don't think i'm going to tell a police officer i killed a girl if i didn't kill her. why would you do it? >> i was a 20-year-old kid, 2300 miles away from my real home. they scared me so bad, i would have said anything to get away from them, anything to make it stop. >> and barry couldn't get anybody in authority to believe his version of things, though for decades he filed appeals, wrote letters. would anyone ever listen? apparently not. until one of those letters reached him. >> we get 11, 1200 letters a year from people asking for our help. >> this is reverend jim mcklaas key, founder of a group called sen turian ministries. and running with a small staff of six people, paid only through donations, compiled quite a record. over 33 years, the group freed from prison or death row 51 men and women wrongly convicted. >> do you have to be convinced beyond any doubt that somebody is actually innocent? >> yes, we do. we don't take a case on unless we are convinced of the person's innocence. >> so before centurian would commit to his case, the investigators had to check out that confession. there's a signed confession. you ask anybody around the country, of course he did it. >> there have been over 200 men exonerated by dna from sexual assault or murder, convicted, imprisoned, later freed and exonerated. 25% of those men falsely confessed to that crime when arrested under interrogation. >> but they found in the case of barry beach, the chance for dna testing had been lost because all the testable evidence from the case had somehow disappeared from montana's crime lab. the fingerprints were still in the record though, and this was curious, not a single one of them matched barry. neither did any of the multiple sets of footprints left behind as kim's body was dragged from the pickup to the river. and what physical evidence there was did not match barry's confession. what did he get wrong? for one thing, barry told the interrogators that kim tried to get away from him by scrambling out the driver's side of the truck. evidence showed she had actually come out the passenger side door, right where the still unidentified bloody palm print was found. >> it is not barry beach's palm print, it is not kim nees' palm print. after she was attacked inside the vehicle, her killers pulled her out, deposit her on the ground, and one of them closed the door. >> there was more. in the confession beach told the police, his fingerprints weren't found on the truck because he wiped them off. they wondered how could beach wipe off his prints and leave more than two dozen others all over the inside of the truck undisturbed. but a few such oddities didn't match. >> once his confession, it became immaterial and irrelevant to the truth of the matter. >> how could that happen? centurian got a hold of a former sheriff's department employee that fielded a dozen calls between them and the detectives during the interrogation. does that mean the confession was coached or dictated somehow? evidence, well, some of the calls turned out were transcribed. at one point the sheriff tells the detective she was wearing a plaid shirt, kim was, when she was murdered. sure enough, in barry's confession, he says she was wearing a plaid shirt. trouble was she wasn't wearing a plaid shirt. that was wrong. the detectives denied any wrongdoing, said all barry's statements were voluntary and they didn't put any words in his mouth. >> you never got information from dean moum you were able to pass on in the course of the conversation he confessed. >> not one bit. absolutely not. that's totally false statement and allegation. >> but a little digging, they uncovered what is believed to be disturbing information about the louisiana detectives. remember the three louisiana murders the detectives questioned beach about? well, months later the same detectives filed charges against two men from whom they extracted, yes, confessions. their charges were later dropped, those confessions revealed to be false. >> you have detectives with a track record of claiming they've got detailed confessions with people with information only the killer could know, and those are false confessions, and it speaks volumes about what they claim to be the validity of barry's confession. >> if barry beach did not kill kim nees, then who did? that's what makes this case a little different because centurian's team not only believes barry beach is innocent, but that it knows who is guilty. coming up. troubling recollections. >> she was talking about how the wrong person got put in jail. >> what a strange thing to hear. >> gave me the creeps. she said we got away with the perfect crime. >> when "dateline" continues. and delectable frappé is a break from the ordinary. and it all starts with a sip. ♪ there's something for everyone to love from mccafé. does your mouth often feel like it lacks enough saliva to keep it comfortably moist?

the judge would hear much more about this, about, for example, the alleged admissions of guilt by sissy atkinson. >> that i had no knowledge of it. i was not there. >> this man testified that sissy herself told him the story several times. told him about the group of jealous girls, how they hit kim with a tire iron, rolled her body into a river. >> i know for a fact girls murdered kim nees and i know he's not a girl. >> and then there were two witnesses who came forward to say they heard the same story from joann jackson. >> she told us that she and a group of girls took another girl by the water. she said they dragged her, beat her, and things got out of hand and she died. >> joann, why would they do this? and she says she was smart and she was going away to college. >> but if there was a star witness among the many who appeared, stef ee eagleboyd, ten years old, when she sat on a bluff overlooking the poplar river and heard the sound that's ever since been her recurring nightmare. >> i could hear all these girls hollering and saying get her and just other girl saying don't, please. >> judge phillips questioned the witness himself. >> did you hear screaming? >> yes. >> what kind of screaming. >> like a horrible scream. a high pitched, angry scream, hollering, something you won't forget. >> she said she never came forward because of the other things she saw from her perch on the bluff that night. soon after the girls stopped screaming, she said, a police car cruised up to the place where it happened and lingered briefly and left. the police must have known and done nothing, she decided. so she said not a word until she heard barry's story. after all the witnesses testified, it was the state's turn and the state contended that all of them waited too long to come forward, and none was very credible, that barry's confession was much more compelling. >> by every court, the confession has always been upheld. >> the state saw it one way, centurian another. >> we were cautiously optimistic. barry was more confident than we were. he said guys, this judge is going to reverse this conviction. he says i just got a good feeling about this judge. >> oh, but good feelings and desired results do not always agree. after all, the montana attorney general believed as did sheriff dean mallon that none of the evidence exonerated barry or pointed to multiple attackers. >> due to lack of other injuries, we were dealing with one perpetrator as opposed to a large group of people. >> besides, he said, barry's confession and conviction settled the matter. >> if the conviction is expunged, that's a travesty because barry beach killed kim nees. >> they vacate the judgment, it says that your belief and the veracity of that confession was false. >> no, what it says is that someone else killed kimberly nees and no one else killed kimberly nees. >> your confidence is overwhelming. >> good. >> this was the moment for that old cliché, the jury was out. >> all rise. >> except in this case it was a jury of one. the judge, e. wayne phillips, all up to him now. coming up, the judge speaks. >> it was that linchpin that convinced me. >> a rare interview about this remarkable case when "dateline" continues. i don't miss out... you sat out most of our game yesterday! asthma doesn't affect my job... you were out sick last week. my asthma doesn't bother my family... you coughed all through our date night! i hardly use my rescue inhaler at all. what did you say?

you have been whacked so often. >> it is hard to keep your belief up sometimes but he had been faithful. >> and then november, 2011, the decision. a 30 page ruling. it was just hours before the thanksgiving holiday. judge e. wayne phillips ruled there was clear and convincing evidence a jury could find barry beach an innocent man. for almost 30 years, beach had been hearing the word no. and now finally this time it was yesterday. not freedom, not yet, but at least this, a chance to clear his name for good. judge phillips granted a new ial. >> i had just sat down to watch the news and i just started praising god. i was just -- it was so emotional for me. >> it doesn't get any sweeter than this, especially because of all the bitterness that barry had experienced with this case. but finally here was a man, a judicial authority, who heard the evidence and agreed that if a future jury hears this evidence, they would find mr. beach innocent. >> and here was something very unusual, after granting barry beach a new trial, judge e. wayne phillips agreed to sit down with "dateline" and explain his decision. >> i mean, how could you rule as i did on the evidence i had and not think about whether the guy should just be set free. >> the judge stopped free of declaring barry beach innocent. after all, there was that old confession on file. but once he heard stephy talk about hearing the murder happen. >> it was that linchpin that convinced me a jury properly instructed would have said i've got doubt. i have reasonable doubt about this man's guilt. >> and then the judge not only granted beach a new trial but at least until that trial much, much more. >> it is this court's determination that it can release mr. beach on his own recognizance. >> as the state's attorneys vowed to appeal, barry beach was hustled out of the courthouse to a jail down the street, the paperwork was done. and minutes later for the first time in three decades, he was free. >> hello, mom. >> safely in the arms of a woman who through it all has always been with him. >> what was that like? >> unreal, absolutely unreal. citizens didn't even know me, stopped, honking their horns, waving, congratulating. and it has been like that ever since. >> after his release, barry lived in billings, montana with restaurant owner stella and zig zigler. he met him through prison ministries. >> as soon as he got out, cell phone, computer, zip zip zip, he worked at someday i'm going to get out and i'll be ready. >> he started his own maintenance company and parlayed that into job of head of maintenance at a billings motel. barry's boss. >> he was overseeing 3 and $400,000 remodeling projects, had a staff of five people, plus he was part of our senior management team. >> after eight months, barry received permission from the judge to live on his own and fixed up this house, was working to buy it so his mom could eventually move in. he traveled all over montana, responding to requests to tell his story. >> bet you he did at least 50 speeches. >> did he have a message for people that resonated with them? >> hope. there's always hope. >> he has a connection with people, no matter whether it was a politician or a banker he connected with them. >> ex-police officer tom hammel became a friend. >> he was trying to do his best to fit into the community, to be one of a respectful citizen. >> after three decades behind bars, barry beach lived life. he learned to ski, went horseback riding and fishing, enjoyed rodeos, made new friends. >> life is like ice cream. there's 64 flavors of ice cream, you have to try them all. >> all the while knowing the state of montana was appealing the judge's ruling and intended if necessary to put him on trial again for the murder. he, after all, confessed to it more than 30 years ago. it was a day in court barry said he was eager for, to help find the truth. >> justice for kim nees is not going to be served until the whole truth is discovered. and the preparation for a new trial gives me more of an opportunity to discover that truth. >> you a little worried about it? >> no, my god didn't put me where i'm sitting at now to let me down. >> but of course no one can predict the future, no matter how we all may try. >> always knew this kind of sword was hanging over his head, could happen any time. >> he talked about on many occasions i know it is out there, but down deep in our heart, we never thought the probability would finally come. >> but it comes, the future comes, like it or not. coming up. a ruling from the court and some will be stunned. >> it was the last thing we ever anticipated happening.

>> i mean all of us that are convinced of barry's innocence, it was a kick in the stomach. >> the warrant was issued within hours. barry insisted on walking to the sheriff's office to turn himself in. the ziglers went with him. >> he stopped, put his hand on my shoulder, said i hope you know this means i am going to have to go back and serve the rest of my time. i said barry, don't talk like that. i don't want to hear that. very emotional day for us. like losing your family. >> reaction was swift and shocked and sad, from waitresses at stella's. >> very heart breaking, i have seen him work here, and he is an active member of society. >> from barry's boss. >> does barry belong in prison, no, absolutely not. i would trust him with my hotel, i would trust him with my family, i would trust him with anything. >> and of course, barry's mother bobby who waited decades to get her son back and now he was gone. >> i was stunned for days afterwards. just couldn't wrap my mind around it. >> that could be said, too, for barry. back in state prison blue, perhaps for the rest of his life. >> what's it like to be you these days? >> sickening. it was the last thing we ever anticipated happening because i went out there and i did everything right. >> you know, i talked to some people, they said i would have run. i would have just taken off. >> that wasn't my mindset. my word means everything to me and i've looked you in the eyes before and i've told you i did not kill kim nees. that's my word. you have my promise, that same promise i gave the attorney general's office, my legal team and everybody else around me that i would turn myself in, and as hard as it was to keep my word, my word is my bond. >> meanwhile, an internet petition campaign collecting signatures, nearly 6,000 at last count. centurian is planning their next move. >> the federal court i believe will look at this very differently and reverse the conviction which openly will free barry. >> for now and probably for years, barry is walking these familiar sidewalks, eating the same prison food, enduring the same smells and never ending routine that is life without parole. zig and stella are getting up in years as are his mom. >> will you see her again on the outside? >> if there's one thing that's got me concerned, very concerned, it is that. because i will be free again. i am going to walk free again. i just asked my mom tog hang in there with me. >> his little house back in billings is exactly as he left it, as if he died in a car accident or simply vanished, or as if he thought he might come back someday. >> i did 29 years and 11 months. i don't want to do another day. but if you don't think i will, i will fight as long as i have breath. >> we'll keep following barry beach's story. now our second hour of "dateline." this story, too, is all about secrets. >> oh, my god, oh, my god! >> his wife said she saw it all. >> this young kid shot him in the head right here. >> point blank. >> point blank. >> a fire chief murdered, watching a movie at home. >> she started crying immediately, she said what am i going to do. >> each clue stranger than the next. a killer who apologized?

keith's deputy didn't think so. >> i never was concerned about that. >> why not? >> for one thing, it had been four years since we had hired anybody, so nobody is going to sit and stew for four years and then all of a sudden get mad and shoot the guy that didn't hire him. >> but if the shooter wasn't angry over a job in keith's fire department, there was another possibility, one that neighbors of the bryans wondered about. keith often did projects on the house. was the killer someone who wanted a construction job and didn't get it? one neighbor told police a few weeks earlier a stranger had been driving around asking for work as a handyman. he said the man had a funny face and drove an old pickup truck, he also remembered seeing a similar truck the night of the shooting. >> are you interviewing neighbors? are you asking people if they saw anyone suspicious in the neighborhood, if they saw a truck in the neighborhood? >> yes, all of that was going on. >> what were they yielding, anything? >> very little. very little. >> then among the firefighters and their wives, a third entirely different idea was bandied about. no one is sure who said it first, but soon some were wondering out loud if keith hadn't been the intended target at all. >> there was a theory out there that perhaps this intruder was looking for a different fireman. >> and why would anyone think that? not far from the bryans' home lived the oklahoma city fire chief, his name keith bryant. bryan with a t at the end. >> the whole keith bryant theory, that maybe they got the wrong fire chief? >> you know, that did not occur to me until i got to the hospital and that's the first time somebody brought up maybe mistaken identity. >> the buzz reached roger back at the fire house. >> that story did come out that possibly the person that done this got the wrong chief. it could have been anyone's theory as to what had happened. >> surely the oklahoma city chief hired and fired many more people than keith did. had the shooter been angry with him? a friend reached him by phone. he was safe and sound at a conference on the coast the night of the shooting, but there were problems with the mistaken identity theory. the two chiefs didn't look much alike, and the more keith's firemen brothers thought it over, the less likely it seemed. >> i still didn't think that story made sense. >> too far fetched? >> yeah, it is real competitive to get hired on as a firefighter. i just can't see somebody not getting hired and then killing the fire chief and the oklahoma city fire department, i don't think the fire chief really even has anything to do with the hiring process. >> so around mustang the questions were many, the answers few. people were watchful, certainly less at ease. >> i found myself wanting to close blinds early. >> did you have a moment of panic?

>> no. >> you didn't even ask her for the top. she just whipped it off? >> that's right. >> so what are you thinking when she -- >> shocked. >> to investigators, becky's behavior was more than odd, it was suspicious. >> you walked into the interview still giving becky the benefit of the doubt. >> absolutely. >> and you walked out of the interview thinking there's a possibility she's going to become an official suspect. >> at that time there was definitely a possibility, yes. >> when the interview ended, detective mcneil and the other investigator went back to the house and that's where he made a key discovery in the utility room in the clothes dryer, a gun. >> that must have been kind of a bingo moment. >> that was a big moment for all of us because not only was the gun in the driver but the gun was wrapped in a blanket, a shell casing was in there as well, and also a glove. >> did you immediately think about the logistics of becky's story as far as where this man came in, where he exited? >> she had told us that he came into the home, shot keith, and walked directly back out the same way that he had come in. she made no mention of this man going into her laundry room, placing anything in the dryer. >> could there have been any explanation for why the gun was found in the dryer, different route than the route she described? >> if there was i didn't know what that was. >> investigators now suspected becky of lying about details, big and small. but they wanted more. as they analyzed evidence from the scene, a call came in from someone in becky's phone contacts nicknamed becky's prodigy. in fact, they noticed the unusual name when they looked at her phone the night of the shooting. >> becky lives in hugo, oklahoma. >> she's a customer. >> yes, she's a realtor broker. >> actually, becky's prodigy was a man named mark holbrook, and when he learned of keith's murder, he called up investigators. he wanted them to know he and becky had had an affair. when it ended 19 months before the shooting, he apologized to keith and promised never to see becky again, but he wanted cops to know she had been in touch with him recently and a lot. >> she still loved him and that she would be moving so she could be near him, whether he wanted to be with her or not. >> the affair had been a reason behind becky and keith's brief split. now investigators and the ex-lover hatched a plan. record a conversation between becky and her so-called prodigy, maybe becky would give something up to him. three days after keith was shot, becky's ex dialed her up. >> becky, how are you doing? >> thank you for calling me. >> becky seemed concerned about covering up the affair. >> if you could say you knew a broker by that name that you went to school with and that's it. >> she stuck to the story about the intruder that shot keith, she had news about him. >> guy that killed keith killed himself yesterday, we're no longer in danger. >> well, that's good, that's good news. >> i know. i really think it is good. >> we didn't have any information like that, law enforcement had not given her any information like that. >> the call rang all kinds of alarm bells for investigators, but didn't yield a lot in the way of hard evidence. but cops thought they had the goods on becky in another way. by now, they had examined that weapon found in the dryer and concluded it belonged to becky. on september 23rd, the day before keith's funeral, becky was arrested and charged with his murder. >> what was her reaction? >> she seemed shocked. she was yelling things at us. >> an open and shut case? becky's brother said far from it. >> law enforcement here let us all down because what i want is the truth. >> in court, evidence would be examined and the truth would turn out to be more bizarre than anyone could have guessed. coming up. the secret life of the fire chief's wife. >> she just openly told me i had sex with a 29-year-old client this morning and i have a picture on my phone. >> when "dateline" continues. she just graduated and got a freelance gig. it's not going very well. so she's coming to the new samsung experience shop at best buy to find all the galaxy devices she needs. and get personalized demos. which means less of this... ow! you shocked me! ...and more of this. well done, anne. the samsung experience shop. the place to find the latest galaxy devices and get hands-on help. only at best buy stores nationwide.

>> sure, sure. she had a lot of bad circumstances, but i do believe somebody shot keith and ran from that house. >> her attorney says there was a rush to judgment against becky and as a result the state just didn't have the proof to back up the charge. >> i do believe that law enforcement agencies in this day and age have the ability to do a lot of things that were not done in this case. i don't believe they ever looked for anyone, which was a huge part of our defense. >> he is in a little itty bitty pickup going down my street. >> you know becky probably better than anyone else. when you listen to that 911 call, you believe becky is being truthful in. >> yeah, i really do, and it is because she was a very detailed person. she is not being panicky, she's trying to describe, she's trying to think through the process, she's very analytical. >> half the town that prayed for keith when he was shot came to court. >> been a tough year and a half. very tough. >> no cameras were allowed inside the courtroom. as the prosecution came armed with a simple, powerful narrative, becky bryan wanted out of her marriage, so she shot her husband and invented the tale of an intruder. >> shot my husband in the head. >> the case against becky began with a slew of secrets from her personal life. they called to court two men who received explicit texts and pictures from becky days before the shooting. and this man, a former client of becky's, came to the stand and testified they had sex the day of the crime. pam woodard says becky told her about it the day of the shooting. >> she openly told me, i had sex with a 29-year-old client this morning, and i have a picture of his private area on my phone. that's not the word she used. and she said and i feel kind of bad because when i got home, keith had made me a tea. and -- >> alarm bells going off? >> it was the oddest conversation. >> but pam and some of becky's other girlfriends weren't brought to court just to talk about that. >> what was the purpose of you taking the stand and what was that experience like? >> i did not want to take the stand. i was made to take the stand. i was subpoenaed by the prosecution. >> the prosecution wanted pam to testify about becky's obsession with her ex-lover, mark holbrook, aka becky's prodigy. becky confided her feelings for him months earlier, when becky and keith appeared to be happier than ever. >> i said becky, you and keith seem to be really committed to making this work and she said to me oh, i'm a great faker. once i made my mind up about something, i'm a great faker. and my heart just kind of sank. >> the prosecution argued this was becky's motive for murder. she was fixated on her ex-lover and elaborately scheming to get him back. >> she proceeded to tell me she was going to tell the ex-lover she was pregnant. >> so she's saying she's pregnant with his baby. >> i said becky, you're 50 plus years old. >> she said 50-year-old people get pregnant all the time. i said who, where? how does this happen? i never heard of that. her reasoning had just kind of gone out the window at that point. >> how far had she gone with the baby story? >> she wanted somebody that could provide her with positive pregnancy tests. she wanted to have a birth announcement printed up. >> birth announcement? >> birth announcement. >> had a name picked out? >> she had a name picked out. >> mark, that object of becky's obsession also testified, adding this potentially incriminating detail. he said on the day keith was shot becky left him a voice mail, saying she planned to buy a house near him because she was about to inherit some money. to many in court, the implication was that becky had been expecting a life insurance payout. becky and keith's grown sons kept their feelings about their mother's guilt or innocence to themselves, but both testified briefly for the prosecution, as did a parade of investigators and fforensics experts. there was gunshot rest due detected on becky's hand. in the driver with the gun that belonged to becky, a blanket with holes in it, a shell casing and a glove. forensic biologist testified the glove had becky's dna on it. >> i tried to be as open minded as i could, wait and hear all the evidence, but as it went on, i was convinced she was guilty. >> the state argued it was premeditated murder by a woman who had been living a double life. becky's brother and chief supporter wasn't buying it. >> do you feel the evidence was overwhelming against becky? >> if you want to convict her of being a slut, a greedy slut, yeah. not a murderer. >> coming up. questions about the evidence. >> didn't fingerprint the dryer, didn't fingerprint the gun. how do you not fingerprint the gun? >> i was so nervous, my hands were shaking. and next friday on "dateline," written in blood. >> there was blood on the ground. >> a loving mother and father killed, left behind, a family in mourning, and letters sprawled in blood. >> there was obviously some type of message. >> what was the message? the name of the killer? a clue to the motive? would it solve this mystery or add to it. and "hey, they're taking our stuff," no need to panic. walgreens has over 8,000 stores across the country with all your prescriptions on file and just about anything else you might need along the way. because you never know what the road will bring. so swing by walgreens today for all your summer must-haves like snacks and sunscreen, right here. at the corner of happy and healthy. vietnam in 1972.

no, but it happens. that does not make one a killer. >> are you disappointed in your sister? >> lord, no. i mean, i don't like some of the things that i heard, but she's my sister. i love her. >> becky's attorney didn't try to rehabilitate her reputation in court. the evidence of her affairs was overwhelming. but when it came to the crime, the defense told the jury the proof was lacking. >> can you breakdown for us the biggest errors you feel law enforcement made in this case? >> i think tunnel vision. i think that dictated this case from the night it happened. they did no other fingerprinting on any other door. they didn't fingerprint the dryer. they didn't fingerprint the gun. how do you not fingerprint a gun? >> the defense had an explanation for how an intruder could have easily used becky's gun to commit the crime. becky usually left it in her purse, which investigators found in her car in the garage. >> do you believe that the perpetrator she spoke of came through the garage, found her gun in the car, went in and shot keith? >> really what i thought happened, perpetrator came in, got the gun out of the vehicle. >> what's more, that glove with becky's dna on it also had someone else's dna, but the csis couldn't narrow it down, not to keith or anyone else. >> it was actually a very large man's work glove. >> was there gunshot residue on the glove? >> yes. >> it was the theme of the defense's case. csi investigators from the state had been so quick to zero in on becky as the suspect, they committed crime scene malpractice. >> didn't do any contact dna on the gun and that's a very simple process. they didn't do any gunshot residue testing on her clothes, didn't do that on her face, which would have been very, very telling. i mean, there are just things that would have given us reasonable doubt. >> the defense told the jury investigators all but ignored any evidence that pointed to an intruder. becky's neighbor came to court with that story about the suspicious handyman he had seen in the neighborhood, and the truck spotted speeding around the night keith was shot. >> it was something that we felt maybe the perpetrator had been canvassing the area, spying on what was going on in the neighborhood. >> and another witness testified he told police at the time he saw a truck matching the one becky described driving aggressively near the bryans the night of the shooting. >> that was the key to the case. he had a person in a matching truck speeding, driving erratically, that had come up on him, almost hit a vehicle. all within blocks. >> but the statement that witness gave investigators only surfaced a few weeks before trial. >> they didn't follow up on it. there were cameras at two different businesses right there at that intersection. >> and one additional detail to contradict the prosecution's case, becky's brother david testified there was an innocent explanation for the inheritance she mentioned to her ex-lover. she wasn't talking about life insurance. becky was about to inherit a diamond ring. >> it was my aunt's ring. >> an expensive ring? >> very expensive. appraisal at one time was $19,000, some years earlier. so obviously had a little more value. >> more than enough reasonable doubt said the defense. but would a jury agree? the wait for a verdict began. >> i was so nervous waiting for it, my hands were shaking. >> i was holding out hope that the jury would recognize the mistakes that were made and understand that because of those mistakes we may never know who really did it. >> afternoon turned to evening and then the news. the jury was back. >> very nervous, very anxious. my thoughts were with keith's family. >> the verdict, guilty of first degree murder. >> and then when he read guilty, i really didn't feel a whole lot. i didn't feel happy. >> how was your first meeting with becky after her conviction? >> she cried, said she couldn't believe it. >> what has becky told you? >> that she didn't do it. but i still don't know the truth. there are either one or two people on the face of this earth that knows the truth. if becky did it, she's the only one that knows. if somebody else did it, she knows it and that person knows it. if one of those two people come forward and say i did it, then we'll know the truth. other than that -- >> on july 9th, becky was sentenced as the jury had recommended to life in prison without parole. for keith's friends, the trial and its conclusion were only one sort of an ending, tangible reminders of their friend and hero live on, especially in the fire department keith led for so many years. >> what is life like now without your friend, without your chief, without keith? >> we still talk about him, some of the funny things he did. he's a part of our history here now and always will be and we miss him. >> if keith was listening, what would you say to keith? >> that i know he's in a great place and keith would tell us to forgive becky, not to say that she doesn't have to be held accountable and that she doesn't have to suffer consequences because that's a given and that's the right thing, but keith would actually want us to forgive becky. and i know that. and i would just tell keith well done. your time on earth here was well done. that's all for this edition of "dateline." we'll be back again next friday at 9:00, 8:00 central. i'll see you tomorrow on "today." i am lester holt in for all of us at nbc news. good nig the b.a.r.t. strike is looming. about 48 hours to go and still no deal. b.a.r.t. and union leaders ended talks just a few hours ago. >> b.a.r.t.'s general manager says progress is being made on several tentative deals in place. both sides she says are still far apart on key issues. salary, medical and pensions. that news was the bay area bracing for life without b.a.r.t. come monday morning. >> expect
