A mans glove, but whose dna . And a woman with a whole lot to reveal. No, no, no. She talked her talk to me. I was shocked. What would come next . Do you feel she realized some of her secrets were going to be exposed . Mystery in mustang. Heres andrea cannon. Reporter just about 20 miles southwest of downtown Oklahoma City, sits a town called mustang. Once farmers and ranchers dotted the land. Its bigger now but folks still hold tight to their roots. Pretty Quiet Community for the most part. Reporter faith connects community here, and people stay lifelong friends. It is a small town feel. Very much neighbors helping neighbors. Reporter in a place like mustang, neighbors know almost all there is to know about each other, for better or worse. 911, police emergency. Reporter so when the unthinkable happened my husband is laying here gasping for air reporter it would be all the more startling when the secrets came tumbling out. I heard a lot of things that shocked me that i never would have imagined. Reporter had evil invaded mustang . Who would do that . Reporter or come from within . It created a lot of fear for a lot of people. That was my first real whodunnit. Reporter keith bryan was oklahoman to the core, proudly raised in the sooner state. He married his wife, becky, at 19, and they settled in mustang. Cam woodard, an old friend of keiths, rolled out the welcome mat for the bryans when they moved to town. They became an integral part of our church, very active, very grounded, very helpful. Reporter they had two boys, trent and kent. Becky was a good mom, from what i could tell. She was a good mom. Reporter he worked as a fireman, his dream job, in the welltodo Oklahoma City enclave of Nichols Hills. Terry hamilton served alongside keith and if the firemen were like brothers, their wives were like sisters, says terrys wife kim. Keith had a good sense of humor, he was outgoing and he was really driven to succeed. Reporter and he did, promoted all the way to fire chief in 1991. Keith never lost his personal connection with the people he served. He was one of the First Responders to the Oklahoma City bombing. He was. Reporter his bravery made headlines. He worked on that lady that was trapped forever underneath the rubble, and keith wouldnt leave her. Reporter was he a hero in your eyes . I think so. I was pretty proud of him as a friend for that. Reporter as for becky, she was a force in the community, too, working in real estate. Her business often seemed more about the people than the money. Becky had a very selfless side to her, too. There were people that i know of, if they were upside down, she even at times was known to take her own money to closing and help like that. Reporter keith was elected city councilman in mustang. Beckys business was thriving. And their marriage, an example to others. She and keith did some premarital counseling for several years in our church. Reporter so they were counseling other couples on how to have they were counseling other couples on how to have a good marriage. Reporter so it came as a surprise when, in 2010, keith and becky hit a rough patch. The boys were grown and the empty nesters separated. Becky moved out. David reddick, beckys brother, remained close to keith during the separation. He said he wanted to know how could he change to show that love to her in a greater way. Reporter what advice did you give keith . I told him to talk to her about it, that she was sensible. Reporter keith worked hard to win becky back, with gifts and dates and loving notes. Becky came home. He was telling some people that what all he had been through was worth it, because it had made him even that much better of a husband. Reporter in the year that followed, keith kept up his campaign of romance. September 20th, 2011, was no different. Becky was at a real estate conference in tulsa. Keith texted her sweet messages throughout the day. Becky arrived home around 8 30 p. M. A friend came over to chat. Keith, now ever attentive, made them iced tea. After the friend left, becky says she and keith settled down in front of the tv. On the bill that night, keiths choice, a classic scary movie, carrie. Then came the real horror. 911, state your emergency. Reporter it was becky. A young man reporter then the phone cut out. What was she saying . Dispatchers sent police to the house. Headquarters reporter becky called back. I just called 911 on my cell phone. Are you coming to my house . Reporter she said an intruder shot keith in the head. My husband is laying there bleeding on my couch. Reporter the intruder was getting away. Oh, my god hes in a little itty bitty pickup, okay . Hes going down my street. Its like a dark color. Reporter now the brave fire chief who dedicated his life to saving others was in urgent need of help himself. Okay. Ive got to go. Maam, stay on the line with me. Reporter ems and police sped to the bryan house but the questions came just as fast. Who was the shooter, this intruder on the loose and could he be found . An unfamiliar feeling spread through mustang streets and homes. Fear. Coming up, a detective is on the case and shes about to hear something odd from becky bryan. After he had shot keith, he turned to her and said, you know, im sorry, maam. A gunman who apologizes . What kind of intruder was that . My first concern was how are we going to find him . Oh, my god oh, my god who would [ bleep ] do that . Word went out that a brazen intruder had shot fire chief keith bryan in his own home and within minutes, First Responders swarmed the house, securing it as a crime scene. As keith was rushed to the hospital, his wife becky stayed behind. Detectives were on their way as she spoke to her brother david on the phone. She was crying and frantic and i said settle down, it will be okay, whos with you. So her son was there. Reporter jamna hickman, a good friend of the family and wife of a fire chief herself, rushed over to the bryans. I went over and hugged her neck and told her how sorry i was, that god would get us through this, and she said im sorry, i know he was your friend, too. Reporter keiths deputy chief, terry hamilton, reached becky on her cell. So i told her not to worry, they will do a full investigation and theyll find, theyll figure out who did it. Reporter at the house, becky was on the rear patio on the phone with friends and family, repeating the story of the armed intruder. We were sitting in open lot around the patio and i was fearful that they might come back. Reporter you thought right at that moment that this person she described could come back . Yes. I did. We hadnt had anything like that happen before. Reporter tammy mcneal, a detective with the Mustang Police department, was dispatched to the bryan house that night. And mustang being mustang, the victim and his wife were no strangers to the detective. Reporter what was your reaction when you hear its keith . Its concerning to me, because i knew this family. Reporter becky seemed relieved to see a familiar face. She called out my name and asked me toome set by her on the back porch. Then she started telling me about a young man, approximately 25 years old, coming into their home and shooting keith in the head. Reporter what did that young man say, according to becky . She said that after he had shot keith, he turned to her and said, you know, im sorry, maam, but he [ bleep ] hired me. Reporter it seemed like a key detail, this apparent apology and explanation. Becky had also recounted it to 911 dispatchers. He said maam, im so sorry, he said but your husband should have hired me. Reporter do you have a gut reaction about that story . It was concerning to me, because we are a small community. My first concern was, you know, is there somebody out there, where is he and how are we going to find him. Reporter becky described the shooter as a man in his 20s with a big nose and wearing a hoodie. I was trying to get as much information out to other Law Enforcement agencies as well as our officers so they could start looking for him. Reporter was it possible keith knew the man . Keith was in no condition to help investigators. But at the hospital, hopeful news. He was clinging to life. I told her, i said hes going to surgery and she said really. Reporter keith made it through surgery, still in terrible shape, but alive in the icu. When becky arrived, the halls of the hospital were filled with friends, loved ones and keiths firefighter brothers. It seemed half the town of mustang was there praying for keith. How hard was it for you to see keith in that condition . It was very, very hard. You know, i would tell myself you never know, ive heard so many stories of people having head injuries. I know prayer is so powerful and i know he had so many people praying. Reporter first thing that happens when you see becky in the hospital. We come up and hug each other and shes crying. I mean, she started crying immediately when i grabbed her. She said what am i going to do, what are we going to do . Reporter by morning, it was clear, keith would not pull through. Those closest to him sensed it was time to say their goodbyes. What did you say to him . Just i said you didnt deserve this. And i love you. Goodbye. That was it. Reporter at keiths bedside, becky, his wife of 33 years, wept and as keith slipped away, along with the sorrow was the lost hope that he could shed any light on who had done this to him. No one believed keith bryan had an enemy in the world, so as the search for the apologetic intruder got under way, one clue was as simple as the victims name. Coming up there was a fairy out there that perhaps the intruder was looking for a different fireman. Could the killer have shot the wrong man . Fire chief keith bryan, so tough, so brave, spent his career running toward danger. Now his life had been cut short inside the safety of his own home. He left behind two dear sons and the wife to whom he had been so devoted. I think that it was just such a shock and such a huge event and such a tragedy on so many levels. Reporter at the fire house, keith led in Nichols Hills near mustang, the captain could barely believe it. You have that gutwrenching feeling it all exploded right now and you dont know what happened. Reporter must be such a weird thing to hear. It was. Over the years being in this type of work, you tend to get calloused over and hide your feelings but when it hits real close to home, you ask yourself why. Reporter detective tammy mcneal was no rookie but this was the first case of its kind she had ever seen in mustang. That was my first real whodunnit homicide case. Reporter what significance does that have for you . It was very significant. I was nervous. I wanted to of course do a good job and make sure that the right person went to jail for that crime. Reporter to find that person, detectives needed to comb through every detail of beckys eyewitness account. Mcneal and an agent from the Oklahoma State bureau of investigation interviewed her again at the hospital the night of the shooting. 1 23 a. M. In the morning. Whats your first name . Becky bryan. Reporter becky talked about how close she and keith were, especially after they made it through that rough patch. We were quite in love. I didnt even know he loved me until i filed for divorce. But it really came to light. Reporter investigators went over step by step how the shooting went down. What are you looking for when you go into that Conference Room to interview becky . How does this person know keith, can she describe him better, things like that. And the door opened and we were watching a loud movie, carrie and this young kid, about 25 years old, walks into the house and comes over to the carpet, and my husband didnt even have time to turn around. I looked, just in time to see, and then he come up from here and he shot him in the head right here. Point blank . Point blank, right here. Reporter it was then becky said that the shooter turned and spoke. It was unbelievable but the guy, this is what he said, he was actually pretty nice, i knew he didnt want to hurt me because he said im sorry maam but he should have [ bleep ] hired me. Reporter so a polite shooter. Yes, she did describe him that way. Yes. Reporter there it was again, that odd but clearly important detail. Along with his polite apology, the shooter seemed to give away a motive. Was he someone vying for a job in keiths Fire Department . Keiths deputy terry hamilton didnt think so. I never was concerned about that. Reporter why not . For one thing, it had been four years since we had hired anybody, so nobodys going to sit and stew for four years, and then all of a sudden get mad and go shoot the guy that didnt hire him. Reporter but if the shooter wasnt angry over a job in keiths 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 didnt get it . One neighbor told police that 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. Reporter what were they yielding, anything . Very little. Very little. Reporter then among the firefighters and their wives, a third entirely different idea was bandied about. No ones sure who said it first but soon, some were wondering out loud if keith hadnt been the intended target at all. There was a theory out there that perhaps this intruder was looking for a different fireman. Reporter and why would anyone think that . Not far from the bryans home in mustang 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 thats the first time somebody had brought up maybe mistaken identity. Reporter the buzz reached roger streaker back at the fire house. That story did come out that possibly the person that had done this got the wrong chief. It could have been anyones theory as to what had happened. Reporter 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 east coast the night of the shooting. But there were problems with the mistaken identity theory. The two chiefs didnt look much alike and the more keiths firemen brothers thought it over, the less likely it seemed. I still didnt think that story made sense. Reporter too farfetched . Yeah. Yeah. Its real competitive to get hired on as a firefighter so i just cant see somebody not getting hired and then killing the fire chief and the Oklahoma CityFire Department, i dont think the fire chief really even has anything to do with the hiring process. Reporter 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. Reporter did you have a moment of panic . A little bit, yeah. It was a little eerie for a day or two not knowing what was going on. Reporter and while those around mustang wondered who and where this invader was, investigators had found something at the crime scene. It would turn the fear and suspicion right around. Coming up, another key turn in the case. Police question a witness who has a whole lot to reveal. No, no, no. She talked her talk to me. She just whipped it off. I was shocked. In the tightknit community of mustang, folks who knew each other so well for so long began to swap stories, memories of their friend keith, the hero, the dad, the loyal husband and friend. But also stories about his wife and the night keith was killed. Janna hickman, who had rushed to the bryans home that night, was outside with becky and remembered hearing this not long after the crime. I heard her just say that something about it would be hard to sell the house because he had died in the house. Reporter did that sound really callous to you . Being a realtor, i could see her thinking about that. It was a little odd, i thought. Reporter at the hospital, some friends noticed that becky was agitated one minute, eerily calm the next. She wasnt emotional. She was pretty calm, talking to different people. Whenever we met her, she was very calm. Reporter too calm . I anticipated her needing comfort and i went to hug her, and she just kind of held her arms out straight and didnt seem to need that type of consoling. Reporter and instead of sticking close to keiths bedside in his last hours, they thought it was strange that becky was often outside. She was just sitting with her legs crossed up on the bench out with her friends, smoking and just very casual. It was just completely bizarre. Reporter beckys brother david says he knows his sister best, and what the friends saw was just beckys way of coping. In your eyes, was becky acting exactly the way a wife would act after a random senseless shooting . Becky acted just like becky would act if someone come in and shot her husband and she was there. She was panicking, she didnt know what to do, she was doing anything she could to get control of her emotions. Our upbringing was control your emotions. Reporter was becky known for sometimes saying inappropriate things . Stupid things. Reporter maybe at the wrong time . Yeah. Yeah. Reporter that was who she was . Becky wanted to control she did not want to cry. She didnt want to be out of control for herself. Reporter but beckys friends werent the only people who found her demeanor odd that night. Detective mcneal says that their taped interview with becky was full of jarring moments. For example, after telling police how much she loved keith, she had this to say about her fatally injured husband. I bought a condo, moved out and he he was a [ bleep ] for 31 years. She described keith to us in what i thought was an inappropriate manner. Reporter as a matter of routine, they had already tested beckys hands at the crime scene for gunshot residue. In the interview, they asked her what she was wearing at the time of the shooting. So you were wearing the shirt and the pants . Yeah. Yeah. Reporter a tube top and panties that she still had on under new clothes, and that, says the detective, is when the interview took a revealing turn. Wait, wait, wait. No, no, no. Dont take it off. Dont take your clothes off now. I got to put my shirt on. Should have clarified, wait until we finish. She grabbed the bottom of the top she was wearing, pulled it over her head, exposing her bre
