family. >> they had taken her in, they were helping her out. >> i'm proud of you. you're finding god. >> then, one baffling text and she was gone. >> i know i watch a lot of law on order but i have this really gut feeling. >> because i was a mom i just knew she had things to worry about. there was no way she left that baby. >> two moms at opposite ends of the mystery could one get justice from the other? >> this case for sure was an investigator's worst nightmare. >> soon, clues to a hidden life. >> very amorous, romantic wild relationship. >> it was stressful. oh my goodness. >> their worst secrets here, deadly ones. >> it hit me hard. >> it was, yeah. i was scared to death. >> how do you catch a dancing

sprite? you put her in the bottle? can you package the joy she brings? can you keep it when she goes? >> she was like a gravitational pull. >> her name was marie. murray carlson. >> she was magnetic. >> when she was happy she can make the whole world saying. >> live life to the post and you might not have tomorrow. >> and so she offered herself, her goodness, gave her vulnerable heart and stored her secrets until what happens. but she was always that way. was marie? from the time of the very first secrets in her life, she was born in the philippines to a single mother and taken in by the family of an american serviceman. and it was years later when she married that kind serviceman it was actually her father who

said esther bridges, the french europe with was also her sister. >> what was like to find that out? >> i was happy. >> i was really happy because i always thought she was ever since we were little girls. and when they got older they moved to florida and live together in a location that was ideal. >> we chose an apartment is behind a karaoke club so that we can just go there all the time like we were stars. >> and she wore pink, always pink. >> it was her. it was her personality. it's full of life. >> that was trying to put up everyone else with her favorite words. beautiful. >> i said oh she so beautiful, i want to be like her but she's to tell me know you are beautiful. she >> love that word. >> kate barber was like a mother to murray. hers, the second family to take maria and when she was 18 and struggling. >> murray's nickname that i gave her was rosie because she

was always peachy and rosy and happy. >> like she was when she met jeff carlson, and he fell hard. >> and it was like instant. and we spent the night talking. >> one of the chances in that? >> i don't know, faith. . fickle finger of fate, i don't know. >> you know right away? >> yeah. >> so they married and had a daughter named paris. they thought their life together would be grand. murray got a college degree in criminal justice and became a deputy sheriff. >> her ultimate goal was to get into the fbi. but then for all the love between them, there were issues. jeff learned that there were more secrets and as a girl murray had been sexually assaulted in sometimes your love enjoy were chased into a darker place. >> she carried some baggage around and when you're in love

with somebody you tend to overlook certain behaviors. >> the biggest issue was she didn't love herself. looking back on now i can say that she was always looking for love from somebody else to validate her own feelings. >> they tried, but the marriage didn't last. and after that, marie drifted a little. jobs fell through, she had to move frequently. jeff suggested paris than three would have a stable life with him. >> she fought it initially but then agreed it was probably for the best and so paris was with me. >> though she saw pairs often, they called all the time. she always noted on paris. i mean she loved her to death, she was super important to her. it was her daughter. i had concerns about the environment that she was in flint but not marie's love for her. >> they were always close? >> yes.

>> even when they were distant from each other? >> yes. >> and then murray find out what hurt vulnerable loving soul seem to need. >> as actually happy for her because she found god. >> murray had found a spiritual home at a church. it was a fancy kasia drill. but fancy wasn't the point. salvation was. here, finally, marie felt right. >> and she's used to saying you know what? >> james landers, preached the bible for square. preached the sneakers and live streams and youtube this sermons. >> it was a very happening place. >> jason was the youth pastor. >> but more than that, the pastor and his wife james and tanya slanders were known for their big hearts and their charity. and that is one for a third time, a family tuck in murray.

>> she saying she was there until she got on her feet. >> but a whole year won by and then what was coming couldn't be hidden. the story floating around? there had been an abusive boyfriend who abandoned her and left her pregnant. and in july marie gave birth to a baby girl named her grace. the pastor and her wife had taken care of both of them. >> it was explained to me that they were helping her out. the she was down on her luck. >> she was, by all appearances saved. spiritually by face and practically by the past for his wife. so imagine our surprise when a stranger message popped up. >> you still remember the words? >> she said she left for the

beach to do something and she didn't want to try to stop her in her last words were i love and appreciate you all. >> but the biggest surprise? murray did not take her three month old baby. she left grace behind with the pastors wife and right away her sister sensed that something wasn't right. she called her family. >> i know i probably watched a lot of law and order but can you find out what's going on because i have this really that feeling and she says oh you watched too many of those kinds of shows. i'm like, no this is different. >> it was the fall of 2011. the very same time that a detective named nestle cui moore became a mother. in fact as you can see it would've made all the difference. >> you get a better understanding of what it's like to love somebody till the end of the world and back and it was almost like faith attended to tie these two together in a mystery of love and lies lost.

>> she had a heart of gold and loved her paris more than anything in the world. >> but what happened in her life? and how did she end up with another baby? from esta the detectives learned about the divorce and how marie had lost her job, and how the pastor and his wife offered her a place to stay. but the questions about baby grace? esta said her relationship with marie was always supportive, and not judgmental. and when marie didn't tell her who the father was, she didn't push the subject. >> i've never questioned her because marie will tell me in her own time if she wants to tell me. i've learned with my sister i never pry. >> but that was the job of the detectives, nesli and keith, to pry and hopefully, find marie.

church of fort walton beach, florida was far more than just a place to gather on a sunday morning. led by pastor james flanders and his wife tanya, this place was a beacon of charity too. the pastor and his church sacrificed their own needs to send money to the victims of katrina. and when marie carlson needed help they took her in, too. i hate dave >> it's what pastors do for their congregation. kaye >> but now? >> i'm left with -- a missing person who's just

came hey hey hey vanished off this earth. >> a week and a half after marie vanished, or drove hey away, or whatever she did, the detectives went calling on the flanders who said they fully expected marie would return -- -y soon. this was not the first time she took spur of the moments trips, they said. >> never to the point where she shade had to be reported to law enforcement missing, though. she came back. >> although the flanders told the detectives, they were quite worried about marie's state of mind. >> they noticed a downward spiral -- >> that she was going into a depression or something? -y depression state, yes. >> thing was, said the pastor and his wife, marie could have wild mood swings, and they knew she had a diagnosed mood disorder. >> did they tell you that she was bipolar? >> yes, told me she was bipolar. had been taking medication and was off of her medication, probably due because of her giving birth to the child. >> but there was another-y

prescription bottle too. -y >> and then they also showed us a bottle that was empty, you know, that maybe alluding to the fact that she had taken medication and was gonna use it to hurt herself. -y >> the day she left? james told the detectives he was-y so worried about her state of mind that he stayed home from work to tom tom keep an eye on her. >> james says that she was acting up. and he didn't want marie take the baby. >> he was afraid the baby might be harmed or something. >> right. >> then late that beignet afternoon, said pastor james, marie said she was tired, went to lie down, and tanya took the baby out shopping so marie could rest. the pastor said he waited around for a bit, talked to her briefly when she woke up and then went out for a run. and when he returned -- marie and her white mazda pickup truck were gone. i strangely, the flanders said, marie had packed her bags, but didn't take them. >> why would she take off and not take her bags with her? >> anyway, said the flanders, when she didn't come back that day or the next, they drove

around town looking for her. went to the airport. maybe she'd parked her car there >> did they find it? >> they did. james says that he finds it in long-term parking. >> at least part of the mystery was solved, said the pastor. she must have flown off to visit someone. they took her pickup home. so the mazda -- what did you do about that car at when you got your hands on it? >> we searched it. but it was -- you know there was nothing to search. it was clean. >> they went to the airport. >> we checked the airlines. there's nothing. she didn't fly out. >> so why would marie's car be at the airport if she hadn't flown out of there? of course she could have been trying to hide her tracks from snoopy friends and family. or what if someone else took the car to the airport, someone who wanted to make it look like she'd pierre left town. rather fishy. then the detectives had an idea.

you know the machine that spits out tickets when you enter an airport parking lot? that very ticket goes back to the at toll both when you leave. >> keith and i went to the little toll booth where you give the -- >> maybe, thought the detectives, the parking ticket for marie's mazda would tell them not just when it was dropped off but, a more important question, by whom? >> we were thinking let's get a at thumbprint, or a fingerprint on one and went through every single one of them until we found the one at that marie's car had received. >> and yes, they got a print. but no, it wasn't clear enough to tell whose it was. then another thought -- >> hey, let's go pull surveillance video. and of course -- >> you looked at all of it. >> well, no. the video didn't wor --

it wasn't working. >> oh. >> -- during the time that we needed. this case, for sure, was an investigator's worst nightmare. >> dead ends everywhere. >> yes. >> and weeks went by. no sign of marie anywhere. time to embrace the thought they'd frankly, had all along. and it wasn't a good one. at >> keith and i both no longer believed we had a missing person. we believed we were dealing with a homicide investigation. but what's the hardest homicide investigation you can be given? one without a body. >> yeah. >> and we didn't have marie. >> coming up, the startling secret that marie kept from just about everyone. >> i want to put the hand on the stomach -- >> when secrets on the emerald coast continues. ntinues.

happened? where did she go? did she go anywhere? and what about grace, the baby she left behind? who, for example, was the father? churches tend to be behaves so the detectives asked around. >> she was involved in an abusive relationship. >> this is a member of the emerald coast church. >> she found out she was pregnant. and she didn't want to go back to the guy, and didn't want to keep the child. >> in other words, she was going to have an abortion. but pastor flanders and his wife had strong views about abortion. and when they discovered her situation, they offered to help solve her dilemma.

>> they were gonna adopt the baby. >> the flanders'had an older daughter, always wanted another child. but one miscarriage after another -- and so, as this church elder told the detectives, the pastor and his wife came to an arrangement with marie. >> she would stay three months to nurse the baby and at the end of three months, the plan all along was that she would leave. that was my understanding from before the baby was born. >> with the baby? >> no, the baby was a gift for the flanders. >> a gift? maybe. it was just like marie to be generous toward the couple who'd been so good to her. but to skeptical detectives, especially this brand new mother, something about the story didn't sound quite right. the father, for example. in fact, the alleged abusive guy didn't seem to exist. but then they talked to ex-husband jeff. and the story he heard? completely different. and it came directly from marie

when she came to visit jeff shortly after she got pregnant. >> i put my hand on her stomach. and i said, "what's -- what's going on with this? " and she wasn't really showing. and her story at that time was, "well, i'm just being a surrogate for james and tanya. so we did basically the -- a type of artificial insemination." >> well, well, well, the pastor was the sperm donor. in this new story, marie's gift was to be the pastor's artificially inseminated surrogate. but why the conflicting stories? to find out, the detectives consulted three special church ladies, tanya flanders'closest confidants. >> did you have a name for this group? >> we called them the inner circle. >> and the inner circle said yes, tanya told them. but swore them to secrecy. but then, tanya gave up a little more. the method was very home-made. >> i remember them saying, "oh, it was with the -- turkey thingy." >> it was with, like, a turkey baster? >> yeah, if somebody -- yeah, if somebody asked. >> so now she's gotta --

now she's got a secret. >> yeah, at that point. >> wait, at that point? yes. because tanya just couldn't leave it there. the next time, she admitted something very, very shocking. >> and tanya said, "well, we did it the old-fashioned way." >> james and marie had sex. which tanya told the ladies was okay with her. and as months passed and marie started showing, there was a baby shower. but oh, no. not for marie. this baby shower was for tanya. she put a balloon under her shirt for a funny photo with marie. but something here didn't seem quite right. the inner circle had to keep their secret. if the story got out? it could threaten everything she and the pastor had built. >> and as it got more and more and more into weird stuff, it was just that the stakes got higher. right? >> that's right. imagine the secrecy that the inner circle, that tanya

actually told the truth to, that it's james'baby. >> but no room for secrets in an official investigation. the detectives invited james and tanya to voluntarily come in for a chat. but only tanya showed up. and here in this little room at the sheriff's office, she let it all come out. about that night of sake and sex, when grace was conceived. >> yeah. yeah. he had a little bit too. >> you were the only one that was sober? >> but, yes, i was there. >> yes. in the room. but of course she was, said tanya. and almost casually, she revealed the heresy that, should it ever become public, would surely ruin them. >> marie was gonna move in and she was gonna be number two. >> a plural wife. >> yes. >> or whatever you call them. >> a sister wife, i think. >> it was, in short, polygamy. or their home-grown version of it. tanya told detectives she

understood the bargain very well. >> i've always seen a relationship as it's -- it's not -- sex is not a relationship. a relationship is two people coming together. and sex is just a bonus. >> a very secret bonus, of course, kept from almost everyone. but inside the bubble of their relationship, tanya said, they were happy. >> she goes, "you know what? i am so glad that you're gonna be raising grace." she said, "and i am so glad that i'm gonna be able to be here to do that with you." and i thought, "god, you know, how cool is that? " >> but then, then marie gave birth. and it wasn't cool for marie. not anymore. and certainly not adoption. >> every time we started to broach the subject with her, she did get withdrawn. >> so maybe tanya wouldn't get baby grace. maybe marie wanted it all, the baby and james, all for herself.

that's what this member of the inner circle believed. >> but i -- did i hear that from marie, that marie wanted james? >> did tanya strike back somehow? fight for her marriage by getting rid of marie? listen to how church members quoted tanya's words.e to do that, but i could." >> shockers? >> yeah. >> i told him, you're not capable of killing her." but tanya leans over and goes, "well he couldn't, but i could." >> so wouldn't that lead you to, like a bloodhound, direct to tanya? she certainly would have a motive. >> she would. >> tanya, now the only mother figure in grace's life. did she know more than she was saying? did she do something? >> did someone in the church have a confession to make? coming up, a confrontation in

the congregation. >> this is a, forgive my saying, a come to jesus moment? >> it was the hardest thing i ever had to do. >> and divine intervention? a sudden, earth-shaking tip. >> i can remember getting that tip and thinking "no way." >> when dateline continues.

think -- >> an attentive churchgoer might have noticed the intrusion of an odd idea in one of the sermons of pastor james flanders. >> what do you think we'd experience? >> when he mentioned a couple of verses in the old testament that seemed to approve, somehow, of polygamy. >> he wanted to justify his relationship to everybody else through a biblical sense. >> so he went to the old testament and -- and pulled up those few lines that suggest polygamy. >> that's correct. >> a trial balloon? if it was, it quickly if it was, it quickly imploded.

and the very practical polygamy in the home of the pastor stayed carefully under wraps. >> so if the news got out to the rest of the church -- did tanya worry at what might happen there? >> that's what she was covering up. she had to protect james and protect their -- that was their world. >> did she do something to marie, to protect james? two months after marie disappeared the detectives got permission to look at the cell phone records of all three of them. would they prove tanya was with marie when she vanished and thus maybe did something to her? >> the cell phone tower information put her away from the area. >> no. nowhere near marie. so then they checked the cell towers for james's phone, and what do you know. when marie sent that mass text message saying she was leaving town, both her phone and the pastor's were pinging off the same cell tower two blocks from his house. and when marie's mazda was dropped at the airport -- >> we've got james

flanders'cellphone touching towers near the airport. why would his phone be near the airport? >> well, either james innocently drove marie to the airport, and neglected to reveal that, or he drove her car there to cover up a crime. no way to prove it either way. so they were stuck again. which is when jason, the youth pastor, remember him? out of the blue jason came to call. he had something the detectives needed to hear, he said. i mean, that would take a certain amount of courage. >> absolutely. we would've never known about that if jason wouldn't have come forward. >> known what? the secret incident that got junior pastor jason involved. it happened soon after marie disappeared. when a very distraught james asked this church elder for help. >> he said, he goes, i need you to get me out of the country. i said what's going on? i said, does this have to do with maria --

marie? he said, "i can't tell you." never once said anything to me else, just it's bad. >> james seemed suicidal, said the elder. so he called a doctor friend. and the doctor committed the preacher to a psychiatric ward for ten days during which time jason anderson took over preacher duties. but then jason heard things. not about what happened to marie, but about polygamy. with other church leaders, he confronted james and tanya. >> this is a, forgive my saying, come to jesus moment? >> it was the hardest thing i've ever had to do, myself, personally, was to confront my pastor. >> this -- your mentor, your senior guy. >> yeah, right. sure. >> and james admitted it. he had been sleeping with two women, in the same house. but then, youth pastor jason told the detectives, in that cloistered setting, james kept talking, and told a terrible story. >> him and marie had had a

physical altercation before she went missing. and she had scratched him on his arms. >> james insisted marie was still alive the last time he saw her. >> i was just so in shock of everything. >> that was it. he could not continue as pastor. james would have to resign. he announced that he and tanya were leaving town. >> unless he was open and honest about everything then we can move forward with some sort of process of restoration, the only other option would be for him to step down. >> they were supposed to leave the following morning to say goodbye to some church members. and lo and behold, around 12:00 or 12:30 they'd gotten in that truck and they hauled butt. they went to arizona. >> they fled. >> like thieves in the night

with baby grace. it was a few days after they left when jason went to the police to tell his disturbing story. >> that they had a physical run-in the day that she went missing. >> then a piece of luck. before they left, marie's friend kay had asked the pastor and his wife for marie's belongings. they gave her marie's computer. the bad news was it had been erased but -- >> i brought it into the sheriff's department for them to take a look. >> we had our forensic tech reanalyze the computer and it gave us a beautiful copy of her phone download that she had done when she backed her phone up. >> wow. >> but maybe it wasn't so lucky. there were thousands of text messages, but they were an unreadable jumble of symbols and words. >> this particular coin though -- look at this, marie shot this video that did survive. showing the pastor hawking gold and silver online, apparently while running the church.

>> valuing this coin at over $500. let me tell you, that's exciting stuff. >> was james just a pastor? or part time flim-flam man? so this is where things stood when an anonymous tip came in. >> startling. if true, it would solve the case. >> and in the tip, it says that james buried her in the backyard. >> that's some tip. >> yeah. i can remember getting that tip and thinking, "no way." like, who would -- who would kill somebody and bury them in their own backyard? >> could be bogus, of course. just another false lead. but nesli was hopeful. >> we brought cadaver dogs and ground penetrating radar and -- we didn't find anything. >> nothing? >> nothing. >> no body. so what happened to marie? more months went by. police kept trying to speak

with james but got no response. then after a whole year, they tried again and he picked up. >> i had been asked by our attorney not to talk to anyone without him there. >> but he did talk -- talked for two hours, in fact, from his car. at times, sounding like he was the victim. >> what emotions have i felt over the past year and a month, you know? anger at marie for going and not letting us know what's going on, and then back to anger at myself for not making a phone call to get her help. >> i am terrified of the prospect of marie taking her own life. and if she did, and i pray she didn't, i hope she did it very, very, very, very, very, very, very far away. because if they find her one little bone that somehow could be connected with her, there -- it's my fault. i'm sure it's the way people

would look at it, it's james. >> do you know where marie is? >> no, i do not. if i did, i would go get her. >> did you kill marie carlson? >> no. >> and that was that. they were stalled. marie was missing and the case was getting very cold. >> coming up -- new revelations from the pastor. >> they were sending pornographic photos back and forth from the church. >> an answer at last to the biggest mystery of all, where was marie? >> nestle past man out that said i missed her. >> i was pretty devastated. i felt like i missed her. the feeling of i could have found her six months after she was reported missing. >> one secrets on the emerald coast continues. ntinues. and you make horsepower...

i love you so much, and getting graphic details of what he wants to do with her." >> kinda pornographic. >> pornographic. even to the point that they were sending pornographic photos with each other from the church. >> some things are hard to un-see. we'll spare you. oh, and most important? everything stopped the day she disappeared. >> no credit cards, no phones, i thought that was strong evidence that she was in fact dead and not in fact missing. >> and her last conversation with a family member was -- >> she wanted out of the circumstances she was in. but she wasn't gonna leave her baby behind. >> and then there was this -- one of those sermons posted on youtube just a month before marie vanished and now in the evidence file. >> now whenever someone is

backstabbing me, lying about me, gossiping about me, trying to tear me down or whatever, you know what i want to do? my feelings say,'choke the life out of them! ' >> is that what the pastor did to marie? the detectives spelled out their case. circumstantial. difficult. but the prosecutors bought it. and james flanders was charged with second degree murder. persistence paid off. >> we were four and a half years in. most people would've given up by now. >> but, as the pastor waited in jail for his trial his attorney and former church member glen swiatek was optimistic. >> what did you think your chances were, if you went to trial? >> i didn't believe the state had second-degree murder. they didn't have a body. >> maybe not, but as the pastor and his attorney looked at the evidence that might put him in prison for life just before the trial they made a deal.

the state reduced the charge from second degree murder to manslaughter and james agreed to tell them what he did to marie. and where he put her. marie's family grudgingly agreed. >> that was the hardest thing. but i wanted to know where my sister was. i didn't wanna go years and years and years and not know. >> as much as i just absolutely hated to agree to it, i knew it was probably the only way. >> first, as part of his deal, the pastor told the story of marie. of the polygamy arrangement. >> it was as if she was another wife. okay? although we never had a ceremony or anything like that. >> he said marie even had a name for their relationship. >> marie called it a throuple. >> throuple. and then the pastor offered his version of that last awful night.

he claimed that marie was in a downward spiral mentally and erupted after he told her she should be hospitalized for depression. >> she hit me in the chest and i grabbed ahold of her and just hugged as tight as i could, and in the scuffle, we fell down on the floor. and -- when we hit the floor, we hit it hard. when i was realized somethin'wasn't right, i rolled her over and she wasn't breathin'. >> a fatal bear hug? not possible, thought nesli. and then she braced for the answer she'd waited five years to hear. >> did you bury marie in the backyard? >> i'll tell you exactly where it's at. >> is that where you buried her? >> yes. >> at that point, the detective got up and left the room. >> nesli passed me a note that said, "i missed her." >> i was pretty devastated. i was in that backyard in 2012. >> not like you didn't look.

>> yeah. but, you know, human nature. you still have -- the guilt. the feeling of -- i could have found her six months after she was reported missing. >> the pastor insisted that tanya wasn't around, was shopping, knew nothing. >> did you get her buried before -- uh, tanya came back? >> oh yeah. yeah. >> do you wonder whether tanya had more to do with this? >> i think that'll always be in the back of our minds. but you know, i think she may have known more than she wants to say. >> but tanya was never charged. and her defense attorney said she was truly shocked by james'confession. >> i could tell you, as a matter of fact, from having to tell her what happened she did not know. >> later that afternoon, nesli escorted james flanders into his former backyard, where he marked with little flags the spot where he buried marie

carlson, five years earlier. then he fell down on the ground, cried. told her, "i'm sorry." what an act, thought nesli. it took hours, but finally, almost five feet deep, wrapped in a blanket, they found what was left of marie. >> i was shaking. i was crying so much. i lost that there. i like a picture is, oh my god she really instead. she really is gone. i think i went crazy. i don't think i've ever cried so loud. >> nesli, and prosecutor angela mason wept too. >> it's my fault. >> back in court that afternoon, james flanders was sentenced to 15 years. with good behavior, he'll be out in 11.

free to join tanya in arizona. and grace, whose mother he killed. >> he's gonna get to have a life after he's done. marie's gone forever. she doesn't get a life, especially with her kids, which is, for most mothers, the world. >> i'm sure you must formed a complex opinion of his personality is. how would you describe him? >> i think james loves himself more than he loves anybody else. i think he -- i would argue he's narcissistic. >> this case to make the angry? >> it does. >> getting riled up. >> yeah, because for almost five years, she was painted as an individual that left her children, abandon her infant child to live her own life and that wasn't the truth at all.

>> jeff carlson had to tell his daughter, paris, her mom was not coming back. >> wasn't easy. what do you say? you don't know how to prepare them for the future of living with this, he deprived her of her mother. he deserves to rot in prison for the rest of his life. he doesn't deserve to walk and society. >> later, marie's family and many others gathered for a celebration of marie's life. they did her favorite thing. they sang karaoke. and they told us that when her daughter comes to visit her cousin, esta's daughter, the two sit down at the piano and play. make music, just like their mothers, years ago. and grace? >> i wanna tell her all about her mom. it's one of those where i just -- i wanna show her, you know,

like, "your mother really did love you." >> maybe someday she'll know about that uncontainable woman who while she stayed brought joy. marie. i'm craig melvin and i'm natalie morales and this is dateline. >> i felt guilty. i couldn't live with that.lt i said, "i know something and it's terrible." "i'm the only other person who knows the truth. i had to do something. >> he swept her right of her feet. >> i was drawn to him right away. >> a dreamy single dad. wealthy. charming. smitten. >> i'd never been spoiled like that. i remember thinking i was like julia roberts in "pretty woman." >> he'd been through so much.
