here's josh mankiewicz with the night lynsie disappeared. >> sometimes the facts are as clear as the southern california sky. but other times, you have to know where it will look. to see the truth. this man has made a career of noticing what others did not. >> what is his reputation? >> a meticulous investigator. just pours over volumes of audience. and finds things that other investigators do not find. >> correct. >> does this man act guilty? does he know more than he is saying? >> i didn't know anything was going on. >> what about this man? can you believe the story that he is telling? >> i was supposed to pick her up twice. and she -- she did not show up on either day. >> the evidence whisper was not present at any of those interviews. but watching them helped him solve the mystery of what happened to our vivaciously little woman. and bring answers to the mother who loved her. >> i was always proud of her, she was a real fighter. >> lynsie ekelund arrived on july 7th, 1980. she was the youngest of three. maybe that fighting spirit isn't visible in her photos. but her mother nancy said it was always there. lynsie had a passion for animals. she helped out in her spare time at a local shelter. kim davidson, who worked at the middle school, remembers young lynsie also had a sense of compassion. >> i was freezing cold, and i didn't bring a jacket that they. and i felt this little hands up my shoulder. and a sweater that turned around, and it was lynsie and she said i just can't stand watching you shiver. >> she gave back in other ways, her mother says that lynsie would lie about her age so she could give blood. remarkable in itself, because lynsie struggled with their own disabilities. her left arm was paralyzed, her left leg impaired. >> did she ever talk about how she came to -- >> she brought it up to me. and said that she was in a car accident and she was thrown. and when she was a little girl. but very, very matter-of-fact. >> growing up, lynsie needed so much care. her mother nancy was with lynsie. like her shadow. >> she was my only purpose. and my life, it's to make her as normal as she could be. >> by the time that kim met lynsie, her dad and brothers had moved away. kim remembers a very tight family unit of just two. >> how close were lynsie and nancy? >> unbelievably. extremely. >> but as lynsie reached adolescence, that started changing. like a lot of teens, she wanted her own identity. she changed the spelling of her name. from this, to this. by high school, there were girlfriends. even some boyfriends. and by the time that she was 20, after so many years of mom and daughter being each other's best friends and confidence, lynsie began to keep some things in her life to herself. like where she was really headed. one night in february, 2001. >> does it make any sense that she would lie to you about what she was going to do that night? >> i have never known her to lie to me. but you don't know what you don't know. >> it was a friday night, lynsie was in college part-time and working, but still living at home. she told her mom that instead of their usual friday night dinner. she was staying the night with a girlfriend name andrea. someone that nancy had never met. and then a young man named chris came to the door. to pick lynsie up. >> she introduces you to this guy, chris? did chris say hello to you? was he polite? >> but nancy says that something felt wrong. >> i had a feeling about him. >> what feeling? >> i don't know. >> but you put it aside? >> yes. >> of course, she was used to things feeling wrong. she had spent so many years worrying about lynsie. it was a struggle to get go. she did. >> the thing i said to her was remember your seatbelt. and she said, back at you mom, love you. that is the last thing that she said to me. >> nancy locked up the house and went to bed. the next day, lindsay was supposed to call after she was done tutoring two girls from the neighborhood. when the call never came, nancy drove over. and found out that lynsie never showed up at her job. >> all of a sudden, my daughter is not where she is supposed to be. she had taught these little girls for four months about. >> and you have no way of reaching her? >> i had no way. >> nancy ekelund was frantic. >> i started calling hospitals, i called the mark. i was desperate, i thought it was a jane doe in the morgue. >> there was no jane doe, and there was no lynsie ekelund. >> most people who disappear like that, they come back in a couple of days? >> if not 24 hours, yes. >> kareem was a detective with the police department. >> we had no and identified bodies. >> you check the er? >> we checked everything. which everybody. we checked everything. there was just no sign. >> coming up! >> when was the last time that you saw lynsie?

>> were not gonna work hard. and there was a little bit of that with nancy ekelund. >> they were working the case, they brought in the usual suspects. like the boyfriend. >> when you guys were dating, she hasn't been dating anyone else to your knowledge? >> no. >> his name is matthew ramirez, he had been at college with lynsie. they were on and off a bit. but then. >> when i went to her house, she was like, i want to break up. >> as can help in with young romance, what was awful is back on. lindsay and matt were back together in time for the weekend. but not in time for making plans for that friday night. >> she's like, maybe i'm going to san diego and visit with chris and everybody. i told her have fun, be careful, okay? she's like okay. >> then in came the last person known to have seen her. chris, 21 years old. out of school. he told the cops that he was unemployed. lindsay had met him through friends about four months prior. and it turns out, he had never drove lynsie to the house for a sleepover. chris said that that was a lie that lynsie made out for her mother. the plan was to go clubbing all night, in san diego. >> she said, don't tell my mom that we are going to san diego. because my mom won't let us go. or will let me go. or something like that. and definitely don't tell them that were club. >> chris told police that when the night of clubbing went bust, they head out earlier than expected. he dropped off the other girls, he said, and then headed to lindsay's house. chris said that it was after 4 am when he finally got back to lynsie neighborhood. and he said that lynsie was worried that the mom would hear the truck pull up at that hour. and lynsie she asked that he would have dropped her off a corner away. and it wasn't suspicious to police, until they heard from her friends that she would be dropped off right here. chris then went home, and police even found a photo of chris's truck heading home on the right street at the right time. so to the cops, his story added up. and that's when police learned that matthew and chris were not the only man in lynsie life. there was somebody else with both matthew and chris had mentioned to investigators. an older man who drove lynsie around. no one knew his name. they had heard lynsie referred to him as her friend. >> that's all anybody knows him by. as him. >> as her friend? >> yes. >> nancy had no idea that lynsie was friends with any older man. she was about to find out. >> two days after she vanished as you get a phone call? >> yes. >> you are at your wits ends? >> yes. >> and the phone rings, and it's marty. did you know marty? >> no. >> as far as you noted lynsie know marty? >> no. >> the plan was to pick up lynsie at school, but she wasn't there. he said he had money of lynsie that she needed for tuition. none of that made any sense to nancy. >> after lynsie goes missing, nancy, her mother, gets a phone call. a guy name marty. >> marty. >> and what is marty say to her? >> marty says that he has befriended lynsie, he is a friend of lynsie's and he is concerned because he had not heard from her. >> what did you learn about marty? >> marty was not marty. >> he was really marty per gensler, he did not have a criminal record. what he did have was a relationship with lynsie, that he did not tell his wife about. he told police that he would often pick lynsie up and give her rides. but that was about it. marty was 58. >> and she was 20? >> she was 20. >> and they were boyfriend and girlfriend? >> i don't think so. >> so police brought in marty. over two days, they recorded those interviews. at times, on video. and sometimes just an audiotape. >> when's the last time you saw lynsie? >> a week ago. >> i don't think so. >> absolutely. >> absolutely not. >> marty said that he had -- lynsie on the day that he had gone to san diego on a friday. >> did she see when? >> we really didn't believe him. >> they didn't believe him because a tip that they received, a clerk at a local clothing store had called to say that she had seen lynsie and a much older man that match marty's description together at her store. after the day that lynsie went missing. >> i, wasn't there on that day okay? i haven't been in that store. all right? and like i said, i'm like you. i mean, i'm easily identified. okay? i probably, every place i've been with her, would know that i was in there with her, okay? >> it was a very long, very long interview. >> friendly? >> no. no. i remember drilling down on him because i thought that he might know where she was. >> you're a parent? >> yes. >> how many kids? >> two. >> if you had a child, gone for eight days. vanished. vaporized in thin air. would your heart not be broken? >> oh, absolutely. >> do you not feel some compassion for nancy? >> unbelievable. i think that this is a nice girl and this family has had their share of hardships. and this is just, you know, i mean, i feel so, you know, helpless. >> i don't think you are helpless. i think you can help us. >> marty insisted that he could. not that he did not know what happened to lynsie. the detectives were not buying it. >> have you harmed her? >> no. never. >> even by accident? accidents happen? >> i never touched her. okay. you know, i never touched her. >> have you put her someplace where she's left? >> no. no. >> police searched his home, and found nothing. no proof that marty had anything to do with her disappearance. so they moved on to the new suspect. someone closer to lynsie than anyone else on earth. >> dateline returns after the break! you're probably not easily persuaded to switch mobile providers for your business. but what if we told you it's possible that comcast business mobile can save you up to 75% a year on your wireless bill versus the big three carriers? have we piqued your interest? you can get two unlimited lines for just $30 each a month. there are no term contracts or line activation fees. and you can bring your own device. oh, and all on the most reliable 5g mobile network nationwide. >> nancy and lynsie had been wireless that works for you. it's not just possible. josh mankiewicz (voiceover): nancy and lynsie had been it's happening. together all lynsie's life. now alone, nancy waited, ticking off the days, together all lynsie life. but now nancy waited, taking off the days. in the dark about where her daughter, was and about the piece of the investigation. police were not keeping her in the loop. so nancy was delighted when they called to say that they were coming to visit. >> look at the boyfriend, matthew. you look at marty. the older guy, the relationship no one knew about. he denies it. >> right. >> you look at chris, he says i dropped her off and never saw her again. >> right. >> and you look at lynsie's mother? >> you can look at lindsay's mother, you have to. >> so i made my cookies, and all this silly stuff that i always do. >> coffee, right? >> yeah. >> the cops were not coming for coffee. they arrived with a search warrant, shovels, and cadaver dogs. >> i was shocked, that they even suspected me. i did not know but even a search warrant was. >> the house that nancy and lynsie had one shared, was torn apart. >> how did you feel knowing that it was nancy? >> i know that nancy was on the radar for a long time. she had been on the radar enough, to set aside. >> having -- they did just that. they believe that her mother had nothing to do with the disseverance disappearance of her daughter. so they took her off the list. they also took off the boyfriend, matthew. and that he was someone else the time she went missing. that leftist too. marty, who police did not trust because of his secret relationship with lynsie and because he had lied about his identity. and the man who dropped lynsie off at the corner. the last person to see her before she vanished. christopher mcamis. >> do you remember it -- >> yes. >> april 2002, more than a year after lynsie went missing. detectives decided to start over. they brought christopher mcamis back to see if his story still held up. >> i definitely think that lynsie has been, like, either abducted or something happened to her. >> right, well like what? >> i'd really rather, really rather think that she is with friends or something like that. >> police turned up the heat. >> let's talk about the positive. and strip away the nitty-gritty. in my mind, like, in a perfect world. then i want to see if she's okay? >> it's a possibility that she is dead. >> right. >> police thought that chris seemed obviously calm, talking about a friend who may have been murdered. >> now, if it turns out someone should kill, or what do you think should happen? >> find them. >> when they find them then what? >> they go to jail. >> how long do you think they should go to jail? >> as long as it takes. >> like what? >> i don't know. i don't, go to jail for a while. >> that's a strong as you can get out of him? >> that's a strong as we could get out of him. >> not, go to hell. or i'd personally electrocute him? >> no i'd personally electrocute him, go to the gas chamber, she was my friend, she did deserve, that she would not heard of fly. >> the lack of emotion suggested that perhaps chris should move to the top of the list, but it was not evidence. after the interview, christopher mcamis was free to leave, and detectives weren't any closer to learn what happened to lynsie ekelund. and neither was nancy, who remained convinced that her daughter would one day just come home. >> you thought that one day that she would walk back through the door? >> yes. >> she believed it because she wanted to. and because over the years, several people had told her that they had seen lynsie. >> i never saw the front of her friends, they always saw the back of her. and i hung on to everywhere that they said. >> it was torture for nancy, no matter what version of events that you believe. and police still weren't telling them anything. >> nancy, during all this time. feels like she has been certainly caught out of the loop. >> yes, she was pretty angry. we work this case diligently for a long time. at some point you hit the wall. >> at that point there were nine detectives in -- , working drugs, gangs, murder, and cold cases. it was clear that the pd had hit that wall. they would need help on this one. and who they needed was a guy named larry. >> tell me about larry. >> larry is phenomenal. >> phenomenal because what, he sees things that other cops don't see? >> phenomenal, because he sees things that cops don't say. i don't know anybody who could have done a better job than larry. >> the evidence whisperer was about to listen to what the facts of this case were really saying. >> was there something that police had missed, you bet. >> coming up! that picture of the truck spotted on the night of the crime. something about it just does not seem right. but the evidence was where is all over it. when dateline continues! she's been looking for. sotyktu is the first-of-its-kind, once-daily pill for moderate-to-severe plaque psoriasis... for the chance at clear or almost clear skin. it's like the feeling of finding that outfit psoriasis tried to hide from you. or finding your swimsuit is ready for primetime. dad! once-daily sotyktu is proven to get more people clearer skin than the leading pill. don't take if you're allergic to sotyktu; serious reactions can occur. sotyktu can lower your ability to fight infections including tb. serious infections, cancers including lymphoma, muscle problems, and changes in certain labs have occurred. tell your doctor if you have an infection, liver or kidney problems, high triglycerides, or had a vaccine or plan to. sotyktu is a tyk2 inhibitor. tyk2 is part of the jak family. it's not known if sotyktu has the same risks as jak inhibitors. find what plaque psoriasis has been hiding. ask your dermatologist about sotyktu for clearer skin. so clearly you. sotyktu. hi, i'm ben and i've lost 60 pounds on golo.

i'm craig melvin. where was lynsie? the investigation was at a standstill, the detectives had to possible suspects that no evidence linking either of them to a disappearance, enter cold case detective larry montgomery, also known as the evidence was for. could he uncover some crucial clues so many others had missed? here again is josh mankiewicz with the night that lynsie disappeared. >> by 2008, lynsie ekelund had been missing for seven years. the case had gone from cold, to frozen in time. so the pd decided to outsource the investigation. to a cold case unit at the orange county da's office. to a guy named larry montgomery. with more than 30 years working on the side, he has put away his share of bad guys, usually by knocking on doors, but instead he works at looking very closely to the evidence. he doesn't work fast, in fact, he is meticulously slow. and that is just what is called case needed. >> was there anything in the original investigation that struck you as something to be needing to re-examine? >> everything. >> everything that had led the police into that wall. trying to decide between two suspects. >> i mean, i'm concerned about this girl. okay? you know? she is missing. >> marty, lindsay's older friend. who kept their relationship a secret, and lied about his name. and chris. >> it seems like she might be still alive. >> the last person to have been known to see her when she was dropped off at that corner. >> and he in your mind, which of the two was a better suspect? >> no, i don't know until i get into the details. >> you're no doubt aware that you have a reputation for saying god's in the details? guilty or innocent? was it marty or chris? larry needed to consider another possibility. could it have been random? someone who had seen her at just the wrong time. >> so, we have, a bad guy just waiting and hoping that a girl drops out of a call it for 25 in the morning? >> it happens. >> yeah, but you consider that. and then you weigh it. and you go, is that a good possibility? probably not. but still keep an open mind. >> and so, he sat down and read through the entire case file. all of the witness statements, all of the interviews. he did that, for two years. he watched the february, 2001 interview. that police did with a very unhappy mighty. >> did that strike you as tremendously suspicious. that he would go after she disappeared, talk to the mother, and give a phony name? >> if you did not know the background of marty, then absolutely. >> i talk to the mother on the phone, i just gave an identifier, okay? marty rossler, that's what i said. >> right, which is a lie. >> watching that interview, larry chalked up marty's dishonesty as a attempt to save his marriage. >> i don't want my life to be brought into this thing. >> larry also took a closer look at the idea that marty and lynsie were together at that clothing store. after that she went missing. >> i flat wasn't there on that day, okay? >> no one ever found any security video of that. and larry has learned over the years, that well meaning people often get dates wrong. and larry learned a key fact. marty had actually participated in those early searches for lynsie. >> you eliminated marty very quickly that? >> yes. >> marty's behavior matched up with that of an innocent person, not a guilty one? >> that is correct. he is actually doing something that you do when you are looking for lynsie. he was searching. >> so then they turn to christopher mcamis, guilty or innocent? >> he was the last person known to be with lynsie, he told police he drove straight home after dropping lynsie off. yet police found that photo of him heading north, away from lynsie's area. which too can pass this atm camera. -- >> the day of lynsie disappearance, police say at the time that it was not ironclad proof, but suggested that what he said, he actually did? >> correct. >> but when larry compared photos of christmas trucks, with the photos from the bank? he saw something that no one else had noticed. the paint on the back of the side view mirror on his truck, was white. >> what about the track in the photo? >> the track in the photo had a dark spot in that area. meaning, whatever mirrors where their, whatever mayors were there. they were black. >> so it's not the same truck? >> that's right. they were not. >> suddenly, chris's alibi had a big hole in it. larry moved on to his history with women, two ex girlfriends talked to police about how chris would become unhinged by rejection. or what he called, disrespect. larry heard about how chris had crushed a pet crab with a hammer. right in front of one of his girlfriends. because he felt that the crab had killed one of his fish. >> this is a guy with some significant anger issues? >> it certainly appears that way. >> she told me it was from a car accident. >> larry listened to the interviews, and caught him talking some of the time with lynsie. in the past tense. >> it was pretty much stuck like this. >> okay. >> then, he found something in the paperwork from the pd. that proved chris headlight to the police early on. about his whereabouts on saturday, february 17th. the day that she did not come home. chris had told them that he had stayed close to home, but larry checked chris's credit card statement. >> there was one entry. on february 17th. and it turns out that it was in santa clarita, which is 15 miles north of where he lived. >> why would crispy in santa clara? >> that is what i wanted to know. >> digging through the reports, larry found information about crisis that. that he was in construction. and that in 2000, and 2001, he had a job site in santa clarita. >> you can't tell now, but back in 2001. this was a major construction site. now, if chris had told police that he had not worked for his dad that winter. it was unemployment. but larry saw some big cash deposits going into crisis think account. with the unemployment checks. so he thought that chris might have been working for his that off the books. and larry came back, here to ask around. >> and he told you that it was kris's father's construction company? >> chris's father did some of the construction work at that site. >> and chris work? there >> he was one of the tractor drivers. >> is this where you thought to yourself, that is where lynsie ekelund was? >> i thought that the chances were excellent, that if i killed her, and i was in christopher mcamis situation, and i saw a tractor in the middle of nowhere. i might use that track to dig a hole to put her in. >> now, all of the evidence whisper had to do. let's prove it. >> coming up! an undercover operation. were you there? >> yes. >> and you are wearing a wire? >> yes. >> when dateline continues! secret works.

>> quite drastically. i could see that the color in the face went white. >> the police had not found the remains. that was a lie. they did it all the time, it was legal. in fact, larry had tried to find lindsey up at that construction location where chris had worked. and had gotten some interest from the cadaver dogs, but nothing more. just down the street from the house, the pd that had been decided to work with larry was keeping an eye on the action. >> sarah watching while this interview happens on the doorstep? >> yeah, i was sitting ten houses down watching the reporter, undercover police officer, once h>> whahe not >> they broke off surveillance. and brought him in. >> chris, have a seat. >> larry had read all about chris and he looked at a tape of every time that chris had been in for an interview. >> here is what the situation is. >> today, he and chris were going to meet for the first time. >> i have been investigating this case for about two years now. >> larry had a plan to get chris to talk without asking for a lawyer. >> you probably want to know what's going on, what's happening while you're sitting here? >> larry promised to fill him in on the case in detail. figuring, chris would want to know if the cops had the goods. and then maybe he would have something to say. >> we just want to advise you of your rights. which would help. and then after that, i want to explain to everything. >> larry read chris's rights, and then before chris could really respond. larry laid out his case. he said that he knew chris had never dropped her off that night. because the atm photo that had first fooled investigators, actually prove that he was not there. >> it wasn't your truck. but for years, it was thought that it was your truck. and in fact, your truck did not go by that night. it wasn't there. >> he told chris about the credit card statements. and how he found somebody who remembered chris working on the job site. >> all of a sudden? big red flags. you know. you're working. you're up there, when you said you are not. but you said, i don't work on saturday. she disappeared on the saturday morning. and your credit card usage up there is [inaudible] on weekdays except for the day that she disappeared. so you're out there working that day. >> he told chris the lie about her being found. >> we recently got dna that had that truck, against the body. so now we've got lynsie up there, right in the area that you were, right at the time where you did not draw her off. and we have enough to prove that crime. >> and knowing about his anger issues with previous girlfriends. he summoned up a little empathy, to draw kristen. >> i the no you have the ability to be angry. and i don't know what she cause to be that angry. [inaudible] >> chris did not say much, until a little body language revealed that larry was on the right track. >> was that what happened? i don't think it was. so what did she do? [silence] >> larry finished talking. he was hoping that christopher mcamis would give it up. >> i think i need a lawyer to talk to you about this with me. >> well, that's up to you. >> the supreme court had made it pretty clear, if someone declares that they want an attorney. the interview is supposed to stop. until one can be hired, or provided. but in this case, larry was walking a line. believing that asking for a lawyer, isn't the same as wondering if you need one. kareem loomis was watching from another room. >> that's about as close as you can get from and i want a lawyer line apart from saying it. but were you holding your breath when he said that? >> yes. if he didn't confess he was going to walk again. >> dateline returns after the break! the lungs and lower airways. but i'm protected with arexvy. arexvy is a vaccine used to prevent lower respiratory disease from rsv in people 60 years and older. rsv can be serious for those over 60, including those with asthma, diabetes, copd, and certain other conditions. but i'm protected. arexvy is proven to be over 82% effective in preventing lower respiratory disease from rsv and over 94% effective in those with these health conditions. arexvy does not protect everyone and is not for those with severe allergic reactions to its ingredients. those with weakened immune systems may have a lower response to the vaccine. the most common side effects are injection site pain, fatigue, muscle pain, headache, and joint pain. i chose arexvy. rsv? make it arexvy.

[silence] i know my life is ruined now. do you know if i'm gonna get the death penalty for this? >> you're gonna have to ask them those questions. >> then, larry came back, all was meticulous, he wasn't done, he wanted that final detail. >> where was it that you dug the hole and put her? >> where exactly he had left lindsey. he explained to chris that even though they found the remains, which wasn't true, the grave site had shifted over the years from flooding. >> it's treacherous parts. and exactly where you've done the whole. >> with the detectives, he returned to the site that had become the final resting place. >> and right where this tree is, i pulled my truck over and parked it. >> this tree to our left here? >> yes. this tree didn't used to exist there when they did construction. >> okay. >> he wasn't sure of the exact spot. >> it's over in this vicinity. >> way over there? way over here? >> this tree. all the way into that brush. >> it took more than a day of digging to find what was left of lindsey, first they found a shoe, and then a jacket, and then a bracelet. and that's how nancy knew they found her. the coroner confirmed that that's how they found the records. two years after he confessed chris was found guilty of second degree murder. his sentence? 15 years to life. >> he told me that you thought he let this consume your life too much. >> it did, it does to this day. >> well now it's over, what do you going to do? >> i don't know. a new life is opening up to you and i don't know i don't, really have any answers. i just have to get over this. >> and that's all for this edition of dateline, i'm craig melvin thank you for watching. you deserve better than that. i'm hungry, i'm in a hurry, i don't have time to make anything healthy. you could if you had a blendjet. blendjet? it's the portable blender that makes the healthy choice the most convenient choice. i don't know. it seems like a hassle. hahaha! wrong. just pour in some milk, add some frozen fruit, and bam! you've got a nutritious and delicious smoothie. mmm! that is good. you're welcome, sad office guy. get yours today at blendjet.com are we in in an ad? we sure are. we lived in a fairytale where lived in a fairy tale are we in in an ad? where everything was perfect. jayne rager valseca: first day of school. fernando valseca: then, all of a sudden, there's that demon, that black spirit, that darkness. everything was perfect. >> first day of school! >> then, all of a sudden, there is tde
