wood blocks, -- in the military cemetery a few miles south of the canadian border. the final resting spot for a few dozen veterans. many of whom died in combat. this is where he is resting now, major david chalian, who lost his life in 2002. his mother,, surely comes here to visit and then remember, his sister brand to, when she's in town. oh how they are worried that war might put him here. except, war did not. no, there never was a thought back then about would could have been far from combat, what did happen all those strange things down south in north carolina. . fayetteville is an old town, steeped in revolutionary civil war history, smack in the middle of the bible belt. but now, cargo planes buzz in and out of the air force base.

image. it's something that's burned in my brain forever no matter how much i try. here is the person that i love, he's dying. >> by the time the police and the ambulance wild up to the, door it was too late. david shannon, just 40, was dead. all it took with a look in fact four lead active mike murphy to see what happened to major shannon's bedroom was highly intentional >> it was intentional, he was executed. the intruder placed a gun to his had, placed into his head, shot.

>> joan? the shock of it did not help, or the fact that she was sound asleep when it happened. by the time she calm down enough to talk to police she was not very helpful. >> i did not clearly see the person who shot david. i don't know if i saw, or just had a feeling of somebody just leaving the room. but, i format as a shadow. >> did you see a shadow, or did you tell the police it was like a shadow? >> it was just movement, a shadow that left. >> >> she tried to follow behind the hallway but she is worried about the safety of the children so she returned back to the bedroom and that is where she made the 9-1-1 call. >> the children, joan and david 's oldest daughter daisy was out of town, but the two young boys, just seven and ten, slept through it all. unaware of what happened. down the hall was shannon's 15-year-old daughter elizabeth who told the cops she was also in bed, and spending a night with elizabeth was her best

friend vera thompson, also just 15. >> both of those statements were -- they were listening to music and watching tv, and they fell asleep. >> five people in the house and not one saw or heard any useful thing that might help determine who committed this horrible crime. or why. there are many clues either, but that was not necessarily because the killer covered his tracks. >> the home was cluttered in filth. close all over the floor, dishes in the sink, food on the counter tops. >> the crime scene itself, what did that look? like >> it's like finding a needle in a haystack. the house was in such disarray. >> the cops picked their way carefully through the clutter. but they found no fingerprints, footprints, or any usable dna. though on the floor near david's body they found to live bullets for a nine millimeter

semiautomatic handgun. joan confirmed to detectives that the major kept guns in the house, plenty of ammo to, but it could not say where those two live rounds came from. she also tried to help the police make sense of the shadow images that her waking eyes a saw, but she just couldn't. >> i was not 100 percent wide awake and aware of what was going on. there was a lot of blank spots in my memory. >> so, little to go on. except there was one curious discovery of that bedroom, something quite unusual at a family home like this. the question was, what did it mean? >> coming up. solving a murder means finding a motive. >> there must have been something with what he was doing at work. this must of been a hit. >> professional or personal. >> the person who was shot, david shannon, might be familiar with joan. >> when dateline continues.

soundly than startled awake beside him. >> she saw a shadow of a person, just described the subject as a -- >> just like, that in a split second, the kids lost their father. and their life together, over their 11 year marriage, was over. >> david and i had a good marriage. if you are alive, you would say we had a good marriage. i'm-ism, i miss what we had. there is not anybody that would ever be able to replace them. >> murder is really strictly a local event -- news of this one, skipped up country and across the windy prairie to a place called langdon north dakota. that is where the major was from, this is where he grew up, where he became unusual young man. >> he was quiet, he was not one that was dating. he did not have a lot of friends. >> brenda strong is david's older sister. >> he was not into sports.

he just was introspective. >> but his mother, surely, says that david always knew exactly what he wanted to do. >> i'm going to be in the army. that's what he said. >> i will dizzy when he first started saying that? >> maybe six or seven. >> by 19, david had enlisted. he was eventually stationed in upstate new york and that is where he met jones. >> he was funny, he had a sense of humor and he was extremely shy. >> dave it was different than the other guys, how? >> because he treated me a lot different. he treated me like i had value. >> which was something wonderful and a new for joan, sexually abused at 12, abandoned by her parents, married to an abusive husband, had a baby with him in 18, another one born in short order. soon single again, working in a topless club, hooking up with the wrong kind of man.

and that, and then she met her night and her savior. she met david. >> so, before the men had want to do for sex but that was it. this guy wanted you for you? >> he was going to protect without controlling. he treated me like an equal. >> less than a year later, joan asked david to marry her. >> i realized that he was this really, really great guy and i did not want anybody else to have a chance to find that out. >> so, in a small north dakota church, joan became mrs. david shannon. >> i thought he found somebody that was good for him. he was obviously happy. >> and what was your impression of? her >> she just seemed very, nice very sweet, very attentive to him. very much in love. >> they complemented each other, is what they did. >> you, know it sounds almost as if you are talking about a joan as if she was one of your children. >> she was, almost like a daughter to me. yes. >> as for jones a two young

daughters, daisy and elizabeth, david wanted them to be part of his new family. >> because he loved me he loved them. >> and so he did. david shannon became both a husband and a father. >> they were all having a good time, being a normal family. you know, everybody getting along, fighting as you do. he loved them. definitely. >> soon, the shannon's became six with the birth of their two boys. and in 2000, the david took the family south to fayetteville when he was transferred to fort bragg. >> david loved the military, he loved being a soldier. you said talk about somebody having a first love, he loved that uniform. >> and the military had been good to david. he was major shannon by now well on his way to becoming a colonel. that was the phone call that he was really looking forward to from fort bragg. not the one they got that

devastating morning in july of 2002. >> david has been shot. he has been murdered. no, it couldn't be. he wasn't special forces, he must have been into something odd. there must have been something with what he was doing at work that, this must of been a hit. >> we felt that something had gone wrong. he found out something that he was not supposed to have known, and that they hadn't get written to him. >> because it was so execution style? somebody came in there with the intent to kill him? >> with the intent to kill him. >> but he was an odd thing. there is just not any sign of intruder getting into the house. it was raining outside, remember? but, nobody tracked any what footprints inside. >> what she was telling us it did not really, it just did not really matchup at the time.

>> and something else that did not seem to match. stashed away in the bedroom where dozens and dozens of a magazines and videos and a cache of sex toys. when detectives asked what that was all about, joan cheerfully gave them the completely unexpected and very surprising answer. >> i told him that david and i were swingers. >> and suddenly, the investigation turned on its heels and headed in a whole new direction. >> they would need couples and her husband would prearrangement and then they would engage in some type of sexual relation with the couple themselves. >> did that make your investigative mind click into some sort -- of >> the person who shot david shannon might be familiar with joan shannon and the swinger lifestyle might have had something to do with that. >> finally, a possible lead. but the shannon's unusual sex life created a motive for

>> joan and david shannon were swingers, enthusiastic members of clubs who the sole purposes to organize various combinations of spouses swapping. in fact, as joan told police, eat and david had been swinging for years, long before moving to north carolina. but fayetteville, after dark, to their happy surprise offered plenty of fresh opportunities to continue their lifestyle, as it is cold. david discovered, that's a. joan >> we get here and we find a computer and he finds the location of a club. >> right off the bat? >> sure did. >> who knew? it was as of this conservative bible belt state to somehow needed to secret outlets for its more lured desires. >> he would go on the internet and there are a lot of the swinger sites. david would look for people on these swinger websites. >> the swingers club that david found was one of many in fayetteville, and this

and jeffrey attended and at that party p, as well as others, did have sex. but, after this happened, joan and jeffrey started seeing one another. >> that was okay, though, according to the rules that shannon had established. as long as it was just sex and nobody got romantically entangled. anyway, wilson was married with kids. there was no indication that his wife knew what he was up to on the side with joan. >> they had done some one-on-one, which is what they called when the other person was not there. but david always knew when i was with jeff. the relationship with jeff started, it was sexual only. in time it developed into a friendship. >> sometimes, joan even brought her new friend by the house. introduced him to her daughters. >> then, according to jeffrey and daisy and elizabeth, joan fell in love with him, and told jeffrey that she wanted to run

as biden and the four leaders at the japan industry summit summit on friday, debt ceiling negotiations continue in washington with no end in sight. republicans met with white house officials to discuss raising the 31.5 trillion dollar debt ceiling, but left with our progress ahead of the june 1st deadline. , and mourners remember the life of jordan neely in harlem on friday. a street artist known for is -- earlier this month in new york city subway car. now back to dateline. back to dateline welcome back dateline, i'm get craig melvin. in the case of the murdered major, one thing became abundantly clear. nothing was as it seemed in the shannon household. the family harbored secrets. for starters, other army major's wife, a mother of four, it was into a sexual relationship with a married man. but, did the affair lead to murder? once again, keith morrison.

>> it was quiet -- quite an eye-opener. that is, when joan shannon told detectives that she entered now dead husband, major david shannon or regulars in unenthusiastic swingers. but, when joan told that she developed a special one on one thing with a married man named jeffrey wilson, now that was a real lead. could it be that major was the victim of a jealous lover? detective murphy paid a call to wilson, a also a shoulder at fort bragg. >> jeffrey confirmed that he was involved in a romantic relationship with joan. >> where was he when this murder occurred? >> he was actually working at the time of the homicide. >> in fact, a little checking revealed that it was a perfect, unassailable alibi. jeffrey wilson was innocent of murder, that is. but as for a three-month affair with joan, wilson was very cooperative. he revealed every lurid detail.

>> back in april they were probably meeting for sex about two times a week. and angela, of course the murder occurred on july 23rd, it at least four times a week. now >> now deputy day billy west began to flip the idea of a love triangle motive on its head. the way jeffrey wilson was talking, it seemed that the person to have reason to kill dave it was not jeffrey. but joan. >> from jeffrey's point of view, he describes how she was in love with him. that she was not in love with her husband. that she did not want to be with her husband, that she financially could not afford to leave her husband. >> wilson said he kept telling her that he was only in it for the sex. he did not want to run off with her. but, if a secret sex was all he wanted, joan, e said, kept pushing for more. >> this situation actually continued to escalate.

i think it was around july 10th, again that was five days before the murder, jeffrey describes how he talks to joan and john says, i cannot take this anymore. i want to be with you. can't we just runoff together? >> david shannon knew of course that john was saying jeffrey wilson, after, all he invited to jeffrey join them in the first place. but, maybe he was not so happy about the cozy friendship that john seemed to be developing. that broke the rules. >> david told joan that she could no longer see jeffrey because he did see that jonah and jeffrey had become romantically involved. i believe it would have been sunday that she was actually having jeffrey wilson, and actually david's killed early morning hours of tuesday. >> if you ask drone, and of course we did, wilson just did not understand. did not understand that the

affair was actually winding down. >> why would he say that you were in love with him? >> he is very self centered and into himself and believes the whole world loves him. i didn't, and we're actually pulling apart, it was coming to an. and >> really? detectives added up, and here is what they had. the story about some shadowy intruder, it did not seem to check out. the swinging, the affair, the story true or, not that she wanted out of the marriage. oh, and by the way she is stood to clock to 700,000 of insurance money. the detective confronted to joan and she, given her lifestyle, she said, she was not surprised at his attitude. >> he is disgusted. he is automatically prejudiced against me. and focuses on that, and he is determined that he is going to get me. >> back in north dakota, david shannon's family tried to keep up with all of the shocking information, the murder, the revelation of swinging, and now,

joan was telling them that she had become a suspect, to which they replied, joan? not a chance. >> we tried to play the scenario, did you don't have a part in it? none of us can see that she could possibly have done that. it is just not in her nature to do that. she cannot. >> but brenda did have somebody else in mind. >> now elizabeth, i could see. >> elizabeth? shannon's a 15 year old daughter? is it possible she was a cold blooded killer who executed her very own stepfather? the man who adopted her, raised, are provided for her? maybe, said david's sister brenda. daisy and elizabeth were always trouble, said brenda, and when elizabeth hit her teens watch out. >> david and joan did not have the tools needed to deal with

what those two girls dished out. it was boys, drugs, and violence. if she got angry with somebody she would destroy something of others. >> that was hardly elizabeth view of things. she conceded that she was no angel, she acted out all. right never denied that. but, elizabeth always claimed that it was the adults who made it ugly and hostile at home, where arguments not affection were the family routine. joan admits now that she was overwhelmed by the task of a parenting elizabeth, realizing, she said, that she wasn't manipulated easily and often by her daughter. >> i gave up, i had to admit it, but i did a gave up on that child. i did not know what to do. >> so joan turned the task of parenting elizabeth over to major david, the military man. who did what he could to keep military order. >> he was definitely the tough

one. he was the one that would decide the punishment of how long the grounding was going to be. >> a war of wills, dave it would ground her, elizabeth would escape. dave it responded with locks and alarms on her bedroom doors and windows. when she's squirmed out anyways, nothing seemed to work. >> what do you do if you cannot keep your kids at home? you cannot chain them. >> a clear message to david, you cannot control me no matter what you do. >> in fact, just a couple of weeks before his, murdered david called home to north dakota defend. to ask his mother for advice about dealing with that girl. >> i did ask him, for i said would she do something? >> what i mean what you do something? >> do something violent. yes. >> he said i don't think so. >> you asked the question for a

reason? >> yes, because i did not trust her. >> coming up. someone from inside the house that night steps forward. >> she was extremely emotional and came to lay the facts on the table. >> when dateline continues. n dateline continues (rebecca) it wasn't until after they had done the surgery to remove all the toes that it really hit me. you see the commercials. you never put yourself in that person's shoes until you're there.

sudden passing the shocks resumed. as disturbing suspicions began to circulate and grow. and, by the time they laid the major in the ground, the question of who did this dreadful things seem to be heading towards an early answer. it was elizabeth. david's family is convinced that rebellious elizabeth was so full of hate that she actually shot and killed her own stepfather. an opinion supported by several anonymous calls to the fayetteville pd. >> we had crime stoppers and tips coming in saying that elizabeth shannon was actually brought in by the homicide. thompson was telling people about the homicide that was shannon might be involved. >> vera thompson, remember her? that was elizabeth's best friend that was staying at the nice house the night of the murder. please broader in again for questioning, and this time they grilled her.

fayetteville, north carolina is an old mobile home park, quiet, what, it's occluded. and in the summer of 2002 it had a new resident. elizabeth shannon was hold up in a trailer. hiding. >> we received a call saying that she was at such as such a location when we entered the home we found her hiding underneath a futon in the living room. >> they arrested her, took her downtown, read her miranda,

writes and then questioned her. without an attorney. . at the time, elisabeth, remembered, with just barely 15 years old. and what did she say after two hours in that room? >> i told the story. >> the whole story? >> elizabeth confessed it all. every grisly detail of that awful night in the shannon house. assuming, that, is that what she told the detectives was actually through. >> it got to the point where i finally did -- but it wouldn't happened without her. >> her, her very own mother, joan shannon. she insisted that her mom had wanted david dead for months. first, by trying to poison him, then later recruiting one of her friends to kill him. and then finally, >> she was like would you be brave enough to do? this >> to do what? >> she wanted me to kill my dad stepdad.

>> and in 25 years on the job, detective murphy had never heard a story quite like this. >> he pressed, further east, said pushing elizabeth to explain how her mother talked or in a murder. the answer, elizabeth says now, was this. it was love, given and withheld. >> it was not really -- i wanted like a real mother daughter relationship, and that was -- just >> several months prior to the murder itself, your mom was taking her shopping and they're going out. they were actually being a family, there was some type of parental involvement. >> she like that? allot >> she liked it because that was something that she was lacking. >> but, having finally offered her something the she so craved, joan threatened to withdraw it. unless she got that done and used it to kill her father, or so elizabeth claimed. >> it sounds crazy at first, but when somebody is in your

ear, let alone your mother, every day, it got to the point where it was like, normal. i just wanted it to do this to please her. i wanted to do this so that nothing changes between me and her. >> and so, elizabeth said, on that night she took one of her stepfather's many guns arranged ahead of time for way to get rid of it and waited while her parents watched their movie and fell asleep. >> she walked into the bedroom, placed gun over her father's head, squeezed the trigger, then she placed the gun to the chest and fired. >> as far as prosecutor billy west was concerned, elizabeth taylor had a ring of truth. >> i think she did it at the behest of her mother, and in some respects, but to please her. mother >> so, in exchange for her testimony, the dea offered liz a deal. instead of life without parole, she could plead guilty and get

a sentence of 25 to 31 years. >> we felt that was appropriate to offer joan the same plea deal that elizabeth had been offered, so that offer was extended by the state. >> no, i wasn't going to do. it >> why not? >> because when you are innocent you are not going to say something that you did not. >> besides, as a victim david shannon's own mother and sister insisted, elizabeth was a devious and manipulative liar, especially when she got herself in a jam. >> so, it did not sound surprising that liz would try to set up her mom like that because, as a child, if there was trouble liz was usually there. but she always had to share the blame. >> she would blame somebody? else >> even if she was caught red-handed. >> absolutely. elizabeth always share the blame. >> so now, jonah shannon's fate would be decided by a jury. the aid billy west told them

about shown and davids swinging lifestyle, jones affair, jeffrey wilson's claim that she wanted to run away with him, financed with insurance money from david's death. and then there was the allegation that jonah tried to pose poison david. , and testimony from a young man who insisted that phone -- to recruit him to commit the murder and dispose of the gun. but, the dea saved his star witness for last. 15 year old elizabeth shannon herself. who told the jury that joan used the truly devious weapon, maternal love, given and withdrawn, to manipulate her in the murder. >> i can take responsibility for my role in everything, but she was trying to put everything on me. that's the point that i kind of woke up and realized that let me tell the truth. >> was it true? on the stand elizabeth psaki's asian was clear and powerful.

>> while i was testifying, she could not even look at me. >> joan did not testify. she sat quietly and distant as her attorney portrayed liz as a liar and ruthless killer who acted entirely alone when she executed her stepfather. >> she is absolutely cold blooded, she is entirely self interested. she hated her parents. she wanted out. freedom. she would've done anything. when she killed david, she killed the only disciplinarian she ever had. >> the idea that joan manipulated elizabeth was not impossible, said the defense. certainly not for either of her parents they could not keep learn, school they cannot keep in the house, they could not do anything. and then, all of sudden, jones got to get her to kill david? >> the jury deliberated a day

and a half, then, >> it came back. guilty >> my heart dropped, it went numb. it is, like so many things flash through your mind and you realize that life, as you know, it is gone. >> it was so unbelievable,. we >> knew john was innocent and she had just been found guilty. it shattered our world in so many ways. >> joan shannon will spend the rest of her life in prison for orchestrating the murder. she has no chance of parole, no more appeals. and, elizabeth gradually pulled the trigger. she tua sent prison for at least 25 years. courtesy of the deal that she got with the dea. >> i told them from day one that i would not gain anything from lying -- in the process. it does not make sense. >> they are in separate prisons now, two hours apart by car,

but really, a world away. we asked if they wanted to speak to each other and make peace, perhaps. look at our camera, we suggested. speak from the heart. >> i still love you, elizabeth. it is complicated. it's difficult. you are still my daughter. and i know the situation is hard for both of us. i am sorry that i was not a better mother. i cannot go back and change that. >> but, elizabeth did not like this idea. >> i don't have anything to say to her. because it does not matter what i say, he's not going to change. -- she's not gonna tell all these people that she lied. >> in the years following her father's death, joan shannon's two sons, david sons, we're

living in north dakota and grew up in a boyhood home here in langton. his mother became, in joan's absence, their mother and grandmother. the boys believed in jones innocence. visited her sometimes and talk to her on the phone. they were not speaking to their sister. and major david shannon, his remains will spend eternity here, just down the road from home in the old military graveyard under the black prairie sawed in the wind. >> that's all for this edition of dateline, i'm craig melvin. thank you for watching. you for watching ♪ ♪ ♪ >> welcome to morning joe weekend on this saturday morning. let's dive right into the top stories of the week. >> so, after four years of investigating the fbi's investigation into possible collusion between the trump
