that's a story of just absolute insanity. obsession, love, the dangers of online dating. >> it is one of the most desperate love triangles i've ever seen. >> my phone starts blowing up with texts from cari. i hate you. you ruined my life. >> they had been dating for just two weeks. >> and he couldn't believe this woman that had just seemed to easy going was this deranged. she was flat-out stalking him. >> cari's rage seems to be

focused on his ex-girlfriend liz. >> he had absolutely no idea the nightmare his life was about to turn into. >> she says, i have liz tied up in the front of the car. you need to call her, tell her you hate her, you or i'm going to kill her. >> could it be the so-called stalker has actually been dead this entire time? >> i mean, what? almost too crazy to be true, except it's alwal true. >> council bluffs, iowa, is a midwestern city with a small-town feel. it has many hardworking people who are willing to help their neighbors, friendly people. >> it's a quiet rural community. >> on the outskirts of the city, on the border near nebraska, is big lake park. the park is huge.

it's almost 200 acres, and there are lakes, one filled with rainbow trout, hiking trails, and playgrounds. >> big lake park was known to be a place that families frequented. it was very peaceful. >> but what happened here on a cold winter night in 2015 was part of a mystery that stumped police for years. >> on december 5, 2015, a woman was at big lake park taking an evening stroll. she'd gone to the park to think while alone on the walking trill in the dark. she took a seat on a bench to rest for a moment. she was approached by another woman. >> she said a female approached her from behind, told her to on the ground, and then fired a shot at her leg. >> she said the female ran off into the woods and then she felt

it was safe, so she walked this pathway and called 911 because she had left her phone in her car. >> 911, what is the address of your emergency? >> i've been shot in the leg. um, my -- my pant leg is filled with blood. oh, jesus. >> is the assailant still nearby? >> i don't think so. i took off running. >> do you know what she looked like at all? >> no, she was behind me. >> council bluffs police responded. they had a helicopter over, could not find a suspect. >> this was a shocking event to have occur, but no one was able to find this woman with a gun running through big lake park. >> it's a mystery that started three years earlier ten minutes from big lake park in omaha, nebraska, with a man named dave kroupa. >> dave kroupa was a 35-year-old mechanic. i was so fascinated by the fact that dave kroupa was just a normal guy, a really nice guy.

he wasn't the kind of guy you'd expect to find in the middle of a murder mystery. my name is leslie rule and i'm an author. >> leslie rule was so intrigued by this story that she wrote a book about it called "a tangled web." >> for fans of true crime, her last name might sound familiar. rule is the daughter of legendary true crime author ann rule, who wrote the book "the stranger beside me" about her friendship with ted bundy. rule is carrying on the family tradition. >> dave kroupa liked women. he made no secret about that, and he made no apologies. >> dave kroupa was recently separated from amy flora, his long-term mate. they had two children together. >> they'd been together for 12 years. >> and he was on his own for the first time in a very long time. >> dave kroupa moved to omaha in 2012. he got a small, kind of sad,

single-dad apartment. and he got a job at an auto repair shop there. >> i didn't know how to venture back into the dating pool. i'd been out of it for a long time so i felt pretty rusty. i was sitting in an apartment by myself at the time with no furniture. so, internet dating was the thing. that was the way to go. >> the first person dave met on an online dating site was a woman by the name of liz golyar. >> her full name is shanna elizabeth golyar, but she went by her middle name, liz. liz was a single mother with two children, and her kids were about the same age as dave's kids. she had a business, liz's housekeeping. liz loved taking selfies and sending them to her friends. >> i thought was liz was very pretty. i was attracted to her right away, so then we set up a date. >> dave's first dates with liz were at a coffee shop, and they just sat and chatted. >> she was sexy.

she was bright and shiny, and she was very engaging. >> they had a lot of fun together. they got along really well. it was just a very casual thing. >> dave was upfront. he absolutely did not want a commitment. he just wanted to have a little fun, and he was clear with every woman he met that that was the case. >> and dave was starting to meet a lot of women. >> mary. cathy. joyce. beth. margaret. sandra. if the chemistry was there, and the woman was willing, dave was more than happy to explore a sexual relationship. >> i was kind of going wild, just being free for the first time in a long time. >> but dave's outlook on casual hookups changed. when he met somebody the old-fashioned way, face-to-face in a chance encounter. >> six months after i met liz, i'm at the counter managing the shop, and i'm the person greeting customers when they

come in, and an extremely attractive woman walks in the door. >> it's a woman named cari farver. >> she brought her ford explorer into his shop to be worked on. and she was beautiful, a lighthearted air about her. >> when we looked at each other there was a little spark. you know, we both smiled. you know, you feel that sometimes. >> cari farver was a 37-year-old single mother to a 14-year-old son. she was a computer programmer at a big firm in omaha. >> she's showing me something inside the vehicle, and we're standing there, and we're very close, within a couple of inches of each other, and there's some tension. >> cari talked to me about meeting dave. and she was like, this guy, totally not my type, but there was just something there. >> then, a few days later, he came across her profile on the same online dating site that he had used when he met liz.

>> so, cari and i ended up going to applebee's for our first date. we hit it off. as we're getting up to leave, i asked her if she wanted to come over and hang out. and she said yeah. so, we went back to my place, we shared a kiss, and then it got a little bit hotter and a little heavier, and then cari stopped and said, okay, if we're going to do this, and this implying sex, that's all it is. you're not my boyfriend. i'm not your girlfriend. i felt like i hit the jackpot with that. i couldn't have wrote it better. >> one slightly awkward thing, the night of dave and cari's first date, liz golyar came by dave's apartment to pick up some things that she'd left there. >> i walked cari out the front door, and she walked right by liz, and they probably saw each other for six seconds. >> it was just a brief encounter, maybe 10 seconds or less, but this encounter would go on to have lasting ramifications for all three of them. >> cari didn't seem at all bothered by her encounter with liz. in fact, she didn't even mention

it when she visited with her friend, amber. >> she said that during the date she had fun and that she laughed a lot and hadn't laughed like that in a long time, and she didn't know what would happen, but it was working right now. >> cari's job happened to be right around the corner from where i lived, versus an hour from where she lived. >> she had a big project coming up at work. she was working very late hours. dave offered for her to stay at his house so that she wouldn't have to make that commute back and forth. >> i mean, at this point i've known her two weeks and she's got a key to my apartment. i was feeling pretty comfortable with her. >> november 13, 2012, dave wakes up and gets ready for work, and about 6:30 a.m., he leaves for work for the day. >> i give her a kiss and i say, i'll see you later. >> when dave said goodbye to cari that morning, he had absolutely no idea the nightmare that his life was about to turn into. >> my phone starts blowing up with texts from cari.

t.j. maxx, marshalls, and homegoods. november 13, 2012. dave kroupa wakes up and gets ready for work, and about 6:30 a.m., he gives cari a kiss and he leaves for work for the day. >> cari farver was his

girlfriend of two weeks. and they were getting along so well that she sometimes spent the night at his apartment. it was conveniently close to her work, which was just half a mile away. >> she's on the couch, got her laptop out. she's doing her thing. so i've got to go to work. so i give her a kiss and i say, i'll see your later. i had expected to see cari that evening. mid-morning, dave received a text. and he glanced at it. it was a message from cari. >> she texts me and says, let's move in together. which was very left field, because we had already talked about that not happening. as soon as i can i text her back and say, i'm not interested. i can't do that. that's not what we talked about. we haven't known each other nearly long enough for that. almost immediately i get a message back that says, fine, i hate you. i'm dating someone else. i don't want to see you anymore. go away. lots of profanity.

i didn't know what to think. i was blown away. >> she just changed very quickly from the fun and happy person that he had known, just that morning. >> it was a day, maybe a day and a half of radio silence, and then my phone starts blowing up with texts from cari. along the lines of, i hate you. you ruined my life. you're a terrible person. i thought, okay, i don't need this in my life. i dodged a bullet. >> they'd been dating for just two weeks. and he figured that maybe she'd been putting on an act and she wasn't who he thought she was. >> so, who was cari farver? she grew up in the small town called macedonia, iowa. >> macedonia is a very small town. it's very nice place to raise kids because you can let your kids walk down the street without worrying. they can ride their bikes around

town. just a friendly place to live. >> cari was very close to her mother, nancy. they talked every day. >> she had a lot of friends. she was very gregarious. >> by all accounts, cari lived fully. when you look at the photographs, she's vivacious. her hairstyles are constantly changing. she's experimenting with her look and with her life. >> you noticed cari when she walked into a room. she had a laugh, she had a smile. you were drawn to her. >> in an interview that cari did with her local paper for her high school graduation, she said she wanted to be known as always having a smile on her face and for being a little bit crazy. and all of her friends and family say cari was whip smart. >> early on she was -- even in high school, i remember cari being amazing with numbers and computers. >> there was a turning point in cari's life when she was 22 years old and got pregnant.

the relationship with the father didn't work out, and cari became a single mom. >> she decided she was going to bring the baby up by herself. >> she was going to have that baby no matter what and be the best mom she could be. >> max was always at the forefront of what cari did. he was her number one. >> she just doted on him all the time. but i think she was a little overwhelmed, just being on her own in her late 20s. she started developing depression. >> cari had been diagnosed in her 20s with bipolar disorder. >> there was one point when she just pretty much was underneath the covers for a good week, maybe ten days. >> she was scared about it, but at the same time knew that she was taking all the steps that she needed to to keep it in

check and under control. >> she had been seeing therapists and was on medication. there was a couple of times when she just -- she would stop taking the medication because -- "mom, it just, i feel like i'm just numb." >> but by 2012, cari was in a very good place. she'd landed a good job as a computer programmer. >> she was super excited and talked a lot about how that was going to be kind of a life changer for her and max, being able to provide in a better way. >> max was just going into high school. cari was so excited about the classes he was taking and the sports that he was playing. >> ride the waves, max. >> she was his cheerleader. there's some video of cari urging on max as he's water skiing. cari also had a new guy she was dating, dave kroupa. >> in november, cari asked her mother nancy to keep her son max

for a few days while she stayed with dave so she could be closer to work. >> right around the same time that dave got the text from cari asking to move in, cari sent a text to her mother, nancy. >> i started getting text messages that said that she was taking a job in kansas. which totally threw me. when i said something to max about it, he said, "well, she had kind of looked at job down in kansas." so he thought possibly there was a job down there she went to. so i texted her back, and she would not call me and talk to me. normally i would talk to her at least once a day. it was starting to concern me that she wasn't calling me. >> but nancy figured she'd see cari soon because cari's half-brother was getting married in just a few days. >> her son max was to be an usher, and she promised max that she would return for the wedding. >> i was needing to know when

she was going to pick up her son to go to this wedding. she wasn't answering me. >> cari didn't show up to pick up max, and she didn't call. everybody was stunned. that was the final straw for nancy. >> that's when i reported her missing. i called the sheriff's office, and they had somebody come out and they took my report. >> nancy mentioned to the police that cari had been diagnosed as bipolar. >> i said, yes, well, she was on medicati medication. the police jumped on that and said when somebody who's bipolar stops taking their meds, sometimes they can start some really erratic behavior. >> they didn't take it too seriously. she was a grown woman. she was still communicating with people. >> i just wasn't getting a very urgent reaction from the police. and they just weren't concerned about it. >> things are going to get

stranger and scarier. >> cari writes, my favorite thing to do is stand outside your window and stare at you. >> i don't know how many i times i changed my phone number. >> she was no longer just ranting at a boyfriend that things didn't go well with. she was flat out stalking him. >> what do you do when somebody invades every space of your life? >> this man's life is about to become terrifying. let's deck the halls. over video calls. with sweatpants. house plants. and a 3pm happy dance. with pizza buying. and reindeer flying. and just a little joyful crying. with all your family. and all your friends. first bites. and happy ends. it's all essential. in every way. and together. it makes a holiday. let's end the year with what matters. can i get a quarter pounder with cheese? make that two?

what had he done to make her hate him so much? in the space of a couple of hours, she had gone from what seemed like the perfect woman to a spiteful fouled-mouthed nut. >> cari farver is nowhere to be found. her family is bewildered. and the police are suspecting she must be having some sort of breakdown. as for dave kroupa, after the days where he received her first text messages he receives a barrage of angry messages. >> she started texting him a bunch of profanities, calling him names, telling him she hated him. >> they were bad, and they were just all about how bad of a person i am. >> cari was acting like a woman scorned. her messages were filled with

jealousy and rage. >> cari's rage seems to be focused on his on-again/off-again ex-girlfriend, liz, who he had dated before cari. which is confusing to dave, because cari seemed to be so unaffected by her first interaction with liz. and cari is contacting liz directly too. >> liz gets into contact with me and says that now cari is harassing her via text and email. >> she was very upset. she wanted to know how this woman that she just had this chance encounter with at dave's apartment, got her phone number, got her email. >> one day, liz arrived home from work to find that her garage had been vandalized. >> upon pulling into the garage, she found that someone had written "whore from dave" on the

inside of her garage in spray paint. >> liz calls the police and files a report. >> when liz tells police that the common link between herself and cari is dave kroupa, they decide to pay him a visit. >> the police show up at my work looking for me, and they didn't look very friendly. i was the last known person, or at least the assumed last person, to see her. as soon as they're looking at me with those policeman eyes, that got me pretty rattled. i pulled out my phone and said, no, she's lost her mind. she's going crazy. she's harassing me. their tone certainly changed from an accusatory one to, oh, okay, we've seen this before. >> meanwhile, back in iowa, cari's mom doesn't know about any of this. all she knows is that her daughter's missing. >> cari's mother had filed the missing person report with the police, and she was becoming increasingly concerned with each passing day. >> in the weeks after she left, cari was still communicating

with her family. she would send text messages to her mother, nancy. >> when i'd get text messages, i would just say, please call me. i just need to hear your voice. and she would say, well, this has got to be good enough for you. and maxwell started getting texts saying, we're going to be moving you down to kansas. you're going to go to school down there. and he was really scared. it was just shocking to me. >> nancy is so concerned that she takes over guardianship of max in cari's absence. >> in addition to her brother's wedding, cari was missing more family events. she was absent for her own birthday. she missed thanksgiving. she wasn't around when her son, max, turned 15. >> she even missed her own father's funeral. and when she didn't come home for that, her mother knew that something was very, very wrong. >> cari texted, i'm sorry i missed the funeral.

nancy responded, the only way i will know that this is you is if you call me and i hear your voice. >> the weather had changed. it was starting to get colder, we went into her house, and i noticed her winter coat was sitting on the chair. and i thought, she doesn't have any warm clothes on her. what is she going to do? how is she getting along? where is she eating? what is she doing? >> it was terrifying. it was scary not knowing where she is. okay, maybe she had gone off her meds. there had been times in the past when she had thought, maybe i don't need these. >> the texts got mean at one point, too, saying that i wasn't a good mother and that i was controlling. >> in the middle of that bleak winter, only one thing was certain -- people were afraid. while cari's family was afraid for her, david kroupa was growing afraid of her.

>> i would regularly receive 60-plus texts a day, 100 emails a day was not uncommon. and as far as phone calls, hundreds of hundreds. and i had changed phone numbers so many times. it was ridiculous. cari would refer to liz in her messages. >> she is nothing. she's a fat cow. she looks like she lost her puppy. maybe she'll do us all a favor and kill herself, lol. >> she wrote to liz, if you don't keep your hands and lips off my man, i will hurt you. and she seems to be everywhere. on one specific occasion, i was sitting in my la-z-boy with my feet up, watching tv, trying to relax, and it's nighttime and i get a text saying, i see you. you're sitting in your chair with your feet propped up, wearing blue shirt. and those things were true. >> she was no longer just ranting at a boyfriend that

things didn't go well with. she was flat out stalking him. >> cari writes, my favorite thing to do is stand outside your window and stare at you. >> then, finally, there's a clue. >> one night in january, about two months after all of this started, dave came home from work, and there was a vehicle in the parking lot. he got closer to the vehicle, and he recognized it to be cari's ford explorer because he knew it very well. that was how they met. he had worked on the vehicle. >> so i took a picture of the license plate, sent it to the police. >> he had no idea at the time how big of a piece of evidence this would turn out to be. >> it had one perfect fingerprint on it. shall i put her in snow mode? nope! what about off-road mode? nah. sport mode it is. let's see what this baby can do. or... we could check out that farmers market? no! you know what?

in the weeks following cari farver's disappearance, police in two different states are trying to find her, but for two

totally different reasons. >> the police in iowa are looking for cari farver as a missing person. >> but less than five miles away in nebraska, just across the missouri river, police are looking for cari farver as a stalker. somebody that is harassing liz golyar and dave kroupa. >> they're all trying to find cari farver. >> the best clue so far is dave's discovery of cari's ford explorer. >> the police searched the car, and they found no fingerprints except for one. >> there was a mint container found in the car that had one perfect fingerprint on it. >> but that fingerprint didn't match cari, and it didn't match anyone in the fbi's national database. so that lead, so far, is a bust. >> but cari's mother, nancy, doesn't need evidence. she knew in her gut that something had happened to her child.

>> i'd lay awake at night because every kind of scenario was going through your head as to what had happened. >> after cari's father, dennis, died, nancy raney had a dream. and he appeared in that dream. >> i had a very, very, very vivid dream that dennis had come to me, and he said, nancy, don't worry about her. she's with me. but, of course, i was always -- always kept hoping that we'd find her and that she was okay. >> and then about five months after cari disappeared, nancy

gets this astounding phone call. >> i get the call from a gentleman that says that cari is at the siena francis homeless shelter and that she wants you to come pick her up. my heart just started -- i was shaking and i thought, oh, my god. we're going to bring her home, she's going to be okay. >> this was the first big lead they had since the finding of cari's vehicle that they thought might lead to finding her. >> so we go over there and we meet up with the investigator. >> the police had met them there, and they asked nancy and her brother to wait in the car while they went in, and they came back out a few minutes later shaking their heads. cari wasn't there. >> it was such a letdown and i was just devastated. i get this raising my hopes, and then it's dashed again.

>> cari's friend amber also got a message from cari saying that she finally wants to come home. >> she said, hey, i made a really big mistake and i took off for a while and i'm ready to come home now. and i was like, i'm here. let's get you home. i could never get her to say that she would meet me anywhere. >> cari's son, max, is losing hope, but just in case, he reached out to his mom on facebook. >> all it said was hi. and she immediately wrote him back, hey, little man, how are you? he asked her to answer three questions to prove that it was really her -- what his middle name was, what the name of their first boxer was, and what his best friend's name was. and she never responded to that message. >> then cari posts on facebook, i've answered enough questions to prove myself. i'm not missing.

i just don't want to come home right now. >> meanwhile, the stalking of dave kroupa and liz golyar has been escalating. >> as the months went on, he'd received thousands of texts and emails threatening him. >> the messages said things like, i hate you so much i want to drive a knife through your heart. hey, loser [ bleep ] so am i ruining your life yet? >> dave and liz referred to cari as crazy cari. >> oh, crazy cari this. oh, i got another email from crazy cari. >> the trauma that they were both going through brought them back together and they started dating again. >> rude, hostile messages coming to both of their phones as they're both together. >> it was actually extremely common for us to be hanging out and both of our phones would start blowing up with text messages and emails from cari.

>> he had to admit, he was impressed by liz's loyalty. she was pissed at him for inviting a lunatic into their lives, but she was still there. >> and as this is going on, dave is becoming almost numb to all this crazy stuff that's happening almost every day. >> i get an email, and it's a picture of what looks like liz tied up in the trunk of a car and it says, i have liz tied up in the trunk of the car. you need to call her right now and tell her you hate her she's a whore, otherwise, i'm going to kill her. i called liz, and i say, hey, you're not tied up in the trunk of a car, are you? ha, ha. all right, good. goodnight. and at that point, it was just another day. it just wasn't even shocking anymore. >> cari even emailed dave with a

link to an obituary for liz. >> in it she writes, i didn't know her very well, except that she was a whore and a man-stealer. thank god she is gone. >> but as crazy as a fake obituary is, things get even creepier and deadlier. >> i get a call from liz, frantic, freaking out. my house is on fire. somebody's burned my house down. i go over to liz's house and there's fire trucks all up and down the street, and there's fireman walking around, and there's hoses and they're pouring water in the place. >> luckily her children were not home, but many of her belongings were still there, including two dogs, a cat, and a snake. and they all were killed in this fire. >> there is audio of the officer at the scene talking to liz about the fire. >> from what i've seen so far, looking inside, this is -- it's pretty obvious this is an intentionally set fire. >> the guy that i'm seeing, he

has a girlfriend that he dated for two weeks, and she's been stalking me since november. >> do you know her name? >> it's cari. c-a-r-i. she has made threats towards me and my kids. she would -- kept texting me and telling me she wanted to kill me and my kids. >> you would think they were married, as much as she's stalking me. she won't leave me alone. she will not go away. i just wish she would go away. >> i felt very bad for liz because i felt like i'd brought this crazy person into her life. >> two months later, cari strikes again. >> dave's auto shop is vandalized with a message for everyone to see -- dave beats women. in florescent orange spray paint. >> i tripped out. i mean, this is my job, and this is on a main street. >> dave became a nervous wreck. he purchased a gun. he was always on edge.

>> it makes you paranoid. you can't rest. you can't relax. you're always wondering when something else is going to happen and if it's going to escalate. >> we were in bed getting ready to go to sleep. and the next thing i hear -- sounded like a gunshot. ♪ tonight...i'll be eating cheesy cauliflower pizza with extra broccolini. my tuuuurrrrn! tonight...i'll be eating cheesy cauliflower pizza and yummy broccolini!

did you see it? [ laughing ] yeah! i'm a big kid now!

on the one-year anniversary of their first date, cari farver sends dave kroupa a message "to my husband." the email included a photograph of a knife and a note saying that she'd been creeping around in his building. >> the stalking at that point was quite apparent that she had been in and around the building. >> dave kroupa and liz golyar have been the focus of cari's stalking for over a year now. and this has bonded them, but their relationship isn't really serious.

zb zblr. >> we were seeing each other, but she was doing her thing and i was doing mine. >> dave has also been actively trying to meet other women online, but it seems that cari doesn't want that to happen. >> one woman that i never actually met, she spent five minutes on my facebook and that was all it took. she was a target, threatened to be killed, threatened to have their children killed. it was insanity. >> cari seems to be monitoring his every move and keeping a close eye on his female friends. >> in january of 2014, i drove from sioux falls to omaha to visit with dave. i have known dave since high school. dave and i have just always had a special connection. we've always been more than friends. >> we were in the living room of the apartment, just chatting. old times. >> within a couple of hours, his phone was going crazy. >> apparently, cari saw her come

in. i actually got a text to the effect of, i see you in there with that whore. >> he told me that he was having issues with an ex that was stalking him. a few hours later we were in bed, getting ready to go to sleep, and the next thing i hear, sounded like a gunshot to me, which was actually a brick being thrown through the bathroom window. i was in a panic. i didn't know what was happening. the police, they came over, talked to dave for a few minutes. after the police left, dave had me get into the car with him, and he said he needed to go check on liz, because cari had threatened liz in the past, prior to this incident with me. >> despite all this drama, liz

golyar is not scared off, and she and dave try to go on with their lives, even going on a double date with her friend, cherokee. >> they were great together, dave and liz. they joked around. i know liz wanted more, but she wasn't that type of person that was going to push herself onto someone. >> the stalking by cari is this dark cloud in their lives. they'd been trying to get help from investigators for more than a year, but nothing puts a stop to the harassment. >> and it's not just dave and liz that are being harassed. >> dave's ex and the mother of his children, amy flora, was also getting threatening messages from cari. calling her all sorts of names. >> i thought amy was probably going to kill me because she got drug into it.

mentally, it was a huge strain on everybody involved. nothing was being done about it. the police had dropped it off at some point. so, it was just something i had to deal with. being stalked and harassed was just part of life. >> the case had become cold. >> detectives ryan avis and jim doty worked at the pottawattamie county sheriff's office in council bluffs. >> neither avis nor doty had actually been working on the case of the missing cari farver, but they'd been aware of it in the police department. >> we heard about the case. it was kind of water cooler talk around the office. it intrigued us because it was a single mom, who was very into her kid and family and it just didn't make sense to us that she just vanished. >> is there more to it? and is there something else that we're not seeing? it was something that we were both interested in just talking about it, but we didn't have the case file.

>> you don't usually go and volunteer for a case, but this intrigued us enough that we asked, hey, can we take a look at it and see if we can put a fresh new look on it? >> doty and avis asked their superiors if they could take another look at the cari farver case. and so they began looking at it from a new angle. >> jim's going to work it like she's dead and i'm going to work it like she's alive. i'm going to try and prove every which way i can that cari is still alive and is out there, and jim is going try to prove every which way that she is not. >> cari's checking account had no activity. it's not normal for adults to just up and leave and literally spend no money, no one's seen them, and no one's heard their voice. it just didn't make sense. >> and one of the things about these text messages is that they don't look like they're written by cari. they're filled with spelling errors and grammatical errors. and her mother said cari never would have sent messages like

that. >> detectives doty and avis were aware that cari had been diagnosed as bipolar, but they didn't think it had anything to do with why she went missing. >> how many people in the world are bipolar? and they don't just go missing for no reason, whether they take their meds or don't take their meds. >> and life had been good for cari farver. in fact, it had never been better. >> she had good income, a good house. i had come to the conclusion that i could not prove she was actually alive. >> this is a turning point in this because they start to contemplate the idea, could it be that she's actually been dead this entire time? so, if cari farver was dead, what happened to her after she left dave's apartment on that early morning two years before? >> the decision made by doty and avis to reopen the case would be a true turning point. >> if not for detectives doty and avis, chances are this case

would never have been solved. >> they smelled a big fish, a big problem, something really weird. >> this investigation is about to take a left-hand turn that nobody saw coming that is mind boggling. >> everything you thought you knew a was lie. l. this is hal's heart. it's been broken. and put back together. this is hal's relief, knowing he's covered by medicare from blue cross blue shield. and with coverage you can trust, backed by over 80 years of healthcare expertise, we'll be there when it matters most. this is medicare from blue cross blue shield. this is the benefit of blue. this is medicare from blue cross blue shield. frank, could you mute your line please? irresistibly slow-baked, unbelievably crunchy. make some noise. it's snyder's! of hanover!

this is a bizarre and twisted case of fatal attraction. it's about an obsessive woman that would stop at nothing to get what she wanted. >> it's just another one of her schemes to bring dave back into her life and make dave look like the victim. >> how could i not see anything and look so naive or gullible? >> it changes from a missing person's investigation. now it's a homicide investigation. >> is there anyone that you think would want to hurt cari? >> how could this person do this to my daughter? for what reason? >> the key to the case is figuring out if cari is not alive, who has been actually sending these messages to dave and to liz? >> this isn't good.

now this person is armed. they've already proven to be dangerous. >> it was like the killer wanted to keep a keepsake of what she had done. it was just chilling. >> holy christ, this is despicable. >> with no body, no murder weapon, no witnesses. >> i mean, what? by the spring of 2015, 37-year-old single mom cari farver has been missing for over two years. nobody has seen her, and nobody has heard her voice. >> the only sign of her was through texts and emails. >> these include hundreds of violent and threatening text messages sent to her ex, dave kroupa, and his

on-again/off-again girlfriend liz golyar, also known as shanna. >> a lot of people thought she'd just gone off her meds, and she just went off the deep end and left, but i knew that that's not what happened. >> cari's mother, nancy, is convinced that something terrible has happened to her daughter. nancy was really frustrated. she felt the police weren't taking her concerns seriously. while maternal instinct is the most powerful of intuitions, it's not unusual for a mother's concerns to be ignored. cari's mother was not the first woman in the throes of panic to be ignored by people in a position to help. >> i knew what my daughter was like, and she wouldn't stay away this long. something has happened. >> it was as if nobody believed nancy. that something terrible had happened to cari. not until detectives jim doty and ryan avis appeared on the case. >> by the time avis and doty took over, the case had become cold. >> what we did first was just go back to the case file, and we

started looking through everything that the previous investigator had. >> to me, the thing that was glaring was liz. this lady had no involvement in cari's life until all of a sudden she went missing. >> according to liz she only met cari once in this brief encounter outside of dave's apartment. >> all of a sudden she's this focus of harassment. her name was all over all the reports. so to me, there was something with liz. she definitely was a person of interest. >> the key to the case at this point is figuring out, if cari is not alive, who has been actually sending these messages to dave and to liz? >> myself and ryan were not digital experts at all, so we had to call one of our coworkers, tony kava, who is our digital forensic expert, and had him come in, and start working the case hand-in-hand with us. >> cari, or the person -- the imposter who was pretending to

be cari, sent dave about 15,000 email messages over a three-year span. we knew these messages don't seem to really be coming from cari farver, and that was the initial mystery. >> i thought, there's got to be a way we can track down this digital activity. >> when liz was getting all of these messages through the course of investigation, she actually gave her phone to police and allowed them to dump all her files and review them. >> jim and i had the advantage of being the second pair of eyes to look at it and go back over to other details that were maybe overseen. >> one of the things they found when they downloaded liz's phone was a photograph of cari farver's ford explorer. >> we looked at the metadata of that photo, and it was taken about a month before police even recovered her vehicle. somehow liz knew where cari's vehicle was before law enforcement even did. another thing we found on the

phone download, there were six calls that were made to cari's residence. it was using the star-67 prefix to disguise the number. so liz was calling cari six times. this didn't make sense to us because she said she'd only met cari one time passing through a hallway. >> we found an email that cari had sent to dave kroupa. it consisted of a picture of a woman who was tied up. we found that picture of that bound woman in liz's phone, and the metadata showed it was taken from liz's phone. >> they realized that liz had put duct tape on her own mouth and tied up her own hands and crawled into the trunk of a car. >> i wanted to go talk to nancy and tell her that i believed her. i believed her daughter didn't just vanish. the her daughter didn't just leave her and her son alone. that i believe somebody was responsible for what happened to cari, but i couldn't tell her everything we knew at that time because it was still an active

case. >> when he called, he said, can i come out and talk to you? and i was just a little bit short with him, because i thought, you haven't done anything so far. what are you going to do now? i said, okay. so, he came out and he said, i just want you to know, he said, i don't think she left on her own free will. and that was the first time anybody of authority position had told me that. >> she was happy to know we had reopened the case and that we had made some progress. >> i honestly felt like something was going to happen now. >> and this visit leads to doty and avis looking at yet another clue. >> it's a clue that had come up earlier, but now with liz golyar

in their sights as a suspect, their fresh eyes make all the difference. >> so when we went to interview nancy, she informed us that she had received a picture of a check via text message. >> right after cari disappeared, nancy got a text from her, and it said that she had sold all of her furniture and she wanted nancy to let the buyer into the house to let them pick it up. >> i'm to help this person go into her house and get her furniture out of there and here's the check. she texted me a picture of a check from a person that was made out to cari. >> and it was signed shanna golyar, which we knew liz golyar's real name was shanna. >> and the signature is yet another link between these two women, cari and liz, who are supposed to be strangers. >> granted, it didn't give us any answers on what had happened to cari, but we knew liz knew more than she was telling us. >> all signs were pointing back to liz.

>> and then liz herself goes to police with a new suspect. >> i looked down the hallway, and i see another investigator walking liz down our hallway. >> and she says, she's come to this stunning realization. it might not have been cari farver harassing her all along. now, there's skyrizi. ♪ things are getting clearer ♪ yeah i feel free ♪ to bare my skin, yeah that's all me. ♪ ♪ nothing and me go hand in hand ♪ ♪ nothing on my skin that's my new plan. ♪ ♪ nothing is everything. woman: keep your skin clearer with skyrizi. with skyrizi, 3 out of 4 people achieved 90% clearer skin at 4 months. of those, nearly 9 out of 10 sustained it through 1 year. and skyrizi is 4 doses a year, after 2 starter doses. ♪ i see nothing in a different way ♪ ♪ and it's my moment so i just gotta say ♪ ♪ nothing is everything.

police have been taking a close look at liz golyar. >> all of the investigating they had done was leading them to the idea that cari farver was dead, and liz had been impersonating her this entire time. >> looking at liz's phone download, we had the picture of cari's vehicle. we had the star-67 phone calls that liz had placed to cari's home phone number. >> and there's one more piece of evidence. that mystery fingerprint left in cari's car. but so far, police can't find a match in their data base. >> one of the things we did when we took the case is we had that fingerprint compared to liz's fingerprints, and it was a

match. >> doty delivered startling news to dave kroupa. he told him that they suspected that liz golyar was pretending to be cari. >> the police had come to me and said liz is the culprit. but i still hadn't seen any evidence myself. i was either trying to ignore the whole thing or trying to understand how this person i spent so much time with could be this other person i didn't know. >> he never questioned his stalker's identity. she said she was cari, so who else could it be? >> dave would receive messages from cari while he and liz were together. so dave thought, how could liz be the stalker? >> meanwhile, police can't prove that liz murdered cari, and there still isn't enough for an arrest. at this point, police get a lucky break. in december of 2015, liz golyar walked into the pottawattamie

county sheriff's office. >> i looked down the hallway, and i see another investigator walking liz down our hallway and into his office. so i eavesdrop a little bit. i hear liz telling the other investigator something about a harassment report. >> liz leaves and detective avis sees an opening. >> liz golyar coming to us and wanting to talk about something was a huge moment and an opportunity that we could not miss. within 30 minutes of liz leaving our office, i hop in my truck and i drove to her house in council bluffs and just knocked on the door. she opened the door, and i told her i was investigator with the sheriff's office and i had heard she had stopped in. hi. was it shanna? >> yeah, or liz. >> i told her that i didn't have a heavy caseload at the time and i'd be more than happy to help her with whatever report that she had tried to file. she let me come in. we sat down and talked. my sergeant you had just talked

to, and he said that you were trying to file harassment? >> yeah. a harassment. the reports have been made against cari farver. >> cari faber? >> yes. f-a-r-v-e-r. >> i knew who cari was, obviously, and i just played dumb. i wanted her to think that i had no clue of what she was talking about just to lower her guard. >> she used to date my boyfriend, only for about two weeks. >> liz tells avis she's come to this stunning realization -- it might not have been cari farver harassing her all along. >> i'm not reasonably sure if it really is cari farver. >> she believed that it hadn't been cari who was stalking dave all this time after all. in fact, she believed it was amy flora, dave's ex. >> amy flora is dave kroupa's ex-girlfriend and also the mother of his children. all these years, liz thought she had been harassed by cari, but now she thought maybe it was actually amy this whole time

pretending to be cari, and that would make more sense, right? >> they only dated for two weeks, and i don't understand why a person would still be stalking him almost three years later. it's getting ridiculous. she keeps stalking me on facebook. >> so, amy still would like to be with dave? >> i'm guessing. i don't know. >> okay. >> i have no clue. i just want her to leave me alone. >> i then request, hey, could i do a download of your phone to extract those messages? we have a machine that'll plug into your phone. sign right there. you're giving me consent to retrieve the information. in that moment, i was so, like, giddy. like, i can't believe i'm going to download her phone. and she's just going to hand it over to me. >> when liz's phone was downloaded in 2013, liz was a victim reporting a stalker. so only the current information was downloaded. now, however, she was a suspect. and she was unaware that detectives had the ability to download everything on the phone, even things she thought

she had deleted. >> i ran it straight to tony kava. >> tony kava, who is the forensic digital expert, is going to actually start examining her phone. but in the meantime, there is an even more pressing concern. dave kroupa's gun is missing. >> i purchased a pistol for self-protection in case cari would come in the house with ill intent towards me or my children. >> dave came home one evening and noticed something was amiss. >> the box that i kept the weapon in, it's been moved. my stomach drops. i'm just, "oh, no." i open the box. the weapon is missing. so i immediately call the police and tell them i have a firearm stolen. >> liz had mentioned the missing gun to detective avis. she implied that amy flora was the thief. >> do you know what kind of gun it was?

>> a 9 millimeter, i believe. i know it was a smith and wesson, only because i seen the box. >> this isn't good. now this person is armed. they've already proven to be dangerous, so it was a heart-stopping moment. >> the missing gun was in the hands of someone who was about to pull the trigger. >> what is the address of your emergency? ♪ ♪ still warm. ♪ thanks, maggie. oh, alice says hi. for some of us, our daily journey is a short one. save 50% when you pay per mile with allstate. pay less when you drive less. you've never been in better hands. allstate. click or call for a quote today.

-don't trip! -we're gonna leave without ya. and we gotta get going. yea buddy. did you get the extra napkins? napkins? get it at mcdonald's when you buy one of your faves and get another for just a dollar. on december 5, 2015, six

days after dave's gun was stolen, a call was placed to police from big lake park in council bluffs, iowa. >> it was liz golyar. she had been shot, and she was bleeding alone on the walking trail in the dark. >> 911, what's the address of your emergency? >> uh, yeah, i've been shot in the leg. oh. oh, god. oh, jesus. >> liz golyar came here to clear her head and walked out about halfway on this bridge and was approached by a female, she said. the female came up behind her and said, "how do you like [ bleep ] dave?" and then told her to lay on the ground and shot her in the leg. >> do you know what she looked like at all? >> no, she was behind me. >> liz was shot in the thigh. it didn't do any permanent damage. there was a lot of blood, and

she was rushed to the hospital by ambulance. >> at the beginning, liz said she didn't know who shot her, but she kind of changed that story and eventually said amy flora shot her. >> amy flora, dave's ex and the mother of his two kids. to police, this story makes very little sense. >> when i learned that liz golyar had been shot out here, i found it highly suspicious that the day before she felt the need to tell me that dave kroupa's gun had been stolen, too. and less than 24 hours later, she is shot. i mean, it's just odd to say the least. >> i never believed that amy flora shot liz golyar, ever. >> she had an alibi, and the evidence just didn't point to there being anyone else in the park that night. >> it was pretty quickly determined that most likely liz golyar had shot herself. amy flora was cleared nearly immediately that evening. >> another one of her schemes to bring dave back into her life and make herself look like a victim. >> when the shooting happened, this is finally when dave gets it.

>> at this point, dave can no longer deny the truth. it's liz, not cari, who's been tormenting and stalking him for all these years. >> it was undeniable at that point. i knew it was her, and i knew it had to be my gun. >> it was like running into a brick wall in a race car. it would be like if gravity just failed. the first thing my mind did was start to go back to all the things that had happened over all these years. and how did i not see anything? and how could i be so naive or so stupid or so gullible? everything you thought you knew was a lie. >> for dave, the frustration at this point is overwhelming. >> if they don't arrest her soon, i'm going to kill her. >> deputy tony kava is actually on a mission to prove liz is the culprit. >> he has the recent download of liz golyar's phone. and all of the messages that have supposedly been sent from cari farver.

>> he's spending hours of his own free time, more than 3,000 hours, trying to decipher where those messages actually came from. >> liz signed up for upwards of 20 or 30 fake addresses that say they're cari farver, and they're different variations on cari's name or even her real email address. >> some of the very first ones came from carifarver@gmail.com. if you didn't look very closely and you received this message, you would think it was from the real cari farver. >> his patience and his persistence pay off, and eventually he is able to trace the messages right back to liz golyar. >> every account that we look at, every impersonated message, every text message, there's always a connection back to an account that she has, to a device that she has, or to her house. >> kava also discovered that part of her ruse, liz was using an app which actually allowed her to send messages and receive them at a later time. >> she was able to send messages

pretending to be cari, and they would arrive while she was sitting on the couch next to dave. from dave's point of view, liz couldn't have sent it, because she was sitting next to him the whole time. it gave a perfect alibi to liz. >> this must have taken liz 40 hours a week, 50 hours a week. this seemed to be a full-time occupation for her, trying to stalk people and send them messages. >> for doty and avis, the mission at this point is to get more evidence to speed up the investigation. >> we brought her in for an interview about two weeks after she was shot. >> doty tells her he's working on a missing person case. they're trying to find cari farver. >> the case is regarding a cari farver. are you familiar with her? >> barely even know her. >> yeah, yeah. >> i ran into her one time. >> okay, okay. >> just bypassing her, going into dave's apartment to pick up my stuff. >> we developed a bit of a ruse that we were going to employ on liz. we were going to tell her that we'd found remains that we

believed were cari. we've had a pretty significant break in the case. >> okay. >> okay? there have some -- been some remains that have been located. >> okay. >> the initial indication is that these remains are cari. >> okay. >> is there anyone that you think would want to hurt cari? >> i didn't know her long enough to know if anybody wanted to hurt her. >> liz then again shifts the blame away from cari farver towards amy flora. >> she was with him for 12 years. and she stills goes in and out of his life all the time, so -- >> yeah. so you think she could've been the person that did some of that stuff to you? >> i'm just saying as another person who would be possessive of dave, it would be her. >> when i'm sitting across from liz, i knew most likely she was a murderer. even though she didn't look intimidating, that was always in the back of my mind. i knew that she was responsible for whatever happened to cari, and i knew in order for us to solve this, she was going to have to believe that i genuinely thought amy was responsible for all of it.

>> in my head i'm thinking if she was bold enough to go and then shoot you, okay, she could easily be bold enough to have done something to cari. >> and that's where detective doty tells her that he needs her help to get amy to confess to cari's murder. >> we told liz, if you get any type of messages from amy that have anything to do with what happened to cari, to let us know. that it's like gold to me if we had something like that. >> okay. >> because then we could start building a case. >> we knew she'd give us that information because she wants to see amy out of the picture. she wants to see amy in jail. >> police are hoping liz will incriminate herself, give up details about the murder, and possibly lead them to the body. >> this is a genius move by the police. the question is, is it going to work? >> all right. thank you much. i appreciate it. >> you're welcome. ong time. ♪ ♪ before i shop anywhere else online. ♪ ♪ get so much cash back it will be like ♪

help him get amy to confess to cari's murder. >> of course, the police know that amy has nothing to do with cari's murder and that she's not involved in this in any way. >> the role i tried to play was that i wanted to solve cari's homicide, and i believed amy was responsible. so we told liz, if you get any type of messages from amy, anything about what happened to cari, to let us know. >> it took only a few days for liz to play right into their hands. >> we started receiving messages that she said were from amy where amy confesses to shooting liz at big lake park. >> the email said, i shot you, liz, to make sure dave stayed away from you. i got rid of the gun. >> but what detective doty really needs are the details about the final moments of cari farver's life. and he explains this in a phone call to liz. >> see if you could kind of push her for some more info on the

cari thing, what she did to cari and so forth like that. that would help our case immensely if it was more specific. >> so you guys want me to try and email her back? >> i'm leaving that in your court, liz. i mean, if that's something you would feel okay doing, uh, that'd be really helpful for us. >> just a few days later, liz forwards a new email. this one she also says is from amy, and it's got details about cari's murder. >> when i met crazy cari, she would not stop talking about dave and him being her husband. she tried to attack me, but i attacked her with a knife. i stabbed her three to four times in chest and stomach area. and then took her out and burned her. i stuffed her body in a garbage can with crap. >> the details were bone-chilling because they were graphic. >> at this point, detectives

doty and avis pushed liz almost to the breaking point and use her obsession over dave kroupa against her. >> liz golyar's worst nightmare was dave kroupa getting back together with amy flora and potentially reestablishing their relationship, so we decided that maybe we could nudge dave kroupa into moving in with amy. >> shortly after that happens, i get a call from liz. she's bawling on the phone, and she's so upset that amy isn't in prison yet. >> looks like the only person that benefited was her. so she gets to shoot somebody, and then she gets to kill another person. and then she gets to move in with dave, and she gets to be free. and you guys aren't arresting her. >> liz presses doty on why the amy confession email isn't enough evidence to have her arrested. >> it's very graphic on what she did to her, and she's still not arrested. >> i'm trying to build a case. it's very difficult. i would tell liz, hey, we need more information, things that only the killer would know. >> within days, more amy confessions appeared. >> she writes, i really did kill

cari, and i did do it in her own car. >> these emails gave us cari's vehicle as a crime scene. so what we wanted to do was go back and look at that vehicle to determine if that crime happened there. >> this is the third time this car has been searched, but this time, the police actually know what they're looking for. >> we opened up this door. er pulled out the passenger seat and pulled the fabric off the passenger seat. then we found a big red stain right in the bottom of the seat. it was a positive test for human blood. >> felt like we had located the murder scene finally. tangible evidence, finally, instead of digital evidence. >> we took the dna from the blood that we found on the seat, and it was a match for cari farver's dna. it's a huge moment. it changes this from a missing

person's investigation, and now it's a homicide investigation. >> omaha police are now pulled into the case since that's where the murder likely happened. >> i'm a cold case detective in the omaha police department homicide unit. >> take the handcuffs off her. >> detective schneider wanted to talk to liz. she had a warrant for an unpaid traffic citation, so that gave him an excuse to actually go arrest her and bring her in. >> the reason you are brought down here in handcuffs is because you have an misdemeanor warrant here in douglas county. >> once she's actually in the interview chair, detective schneider tells her the real subject of their interview, cari farver. >> the reason you are in this chair right now today is because you have a lot of questions that you need to answer for me. her phone was at your house right after she disappeared.

i want to ask you how you can explain that to me, please? >> she's never been to my house. >> your fingerprints are inside her vehicle. how would your fingerprints be inside her vehicle? >> i don't know, because i've never been in her car. >> you drove her car. >> no, i didn't! i've never been inside of her car. i've never even been around her car. ever. >> your fingerprints are in there. >> no, i haven't. i'm not lying. i've never been around her car. i've never even seen it. >> she definitely was giving me the old evil eye. she was upset, you could tell, by being confronted. >> for years and years people have been sending emails under cari's fictitious accounts. the ip addresses show up to whose house? your house. >> i haven't had internet at my house. >> you definitely see a woman who thinks she's smarter than the police. who doesn't recognize that she's in a mouse trap. >> are you going to sit in this chair and be remorseful, or are you going to sit in this chair and be cold-blooded? because right now, after four years, this -- this family's been looking for answers.

>> detective schneider then confronts liz and tells her he knows that she wrote the so-called amy confession emails. >> why would you create all these emails? >> i haven't created any emails. >> all of these have been coming from your house. >> no, they're not. and i'm not going to be accused of something i didn't do. >> liz is the type of person where it could be 2:00 in the afternoon and you could tell her, "liz, it's 2:00 in the afternoon," and she would say, "no, it's not. it's midnight." the finger's pointing right at you. >> well, then, i'm done talking, and i'm going to have my attorney, because i didn't do anything. >> okay. >> while this interrogation is taking place with detective schneider, detectives avis and doty have gotten a search warrant and are conducting a search of liz's apartment. >> when we were searching her apartment, we found two things. we found cari's digital camera and camcorder. that means at some point, liz

went into cari's house and stole those items from her house and has kept them for years after. >> on cari's camera, investigators find a video taken just two days before cari was killed. she had just discovered that her ford explorer had been vandalized. >> and it's the last known video of cari. >> so, thursday night, apparently someone here in the whopping metropolis of macedonia, iowa, decided max's explorer was not the right color. we're going to go see if we can fix that. somebody thought they were quite the artist. >> investigators now believe it was liz who vandalized the car. >> there's some. all over the hood. >> the police finally had enough evidence to get an arrest warrant. >> but the strongest evidence against liz is actually discovered after her arrest. >> i came to a photo that no one had seen before. >> it was like the killer wanted

to keep a keepsake of what she had done. it was just chilling. this year, our driveways have brought us all closer together. and been our gateways to the world. for over 30 years, lexus has been celebrating driveway moments. in a year filled with memorable ones, here's to one more. the lexus december to remember sales event. experience amazing at your lexus dealer. now walmart can help check off your gift list with free curbside pickup, fast delivery from your walmart store, or gifts shipped right to your door. let's end the year celebrating. ♪ let's end the year celebrating. what makes sanpellegrino drinks so unique? the time to carefully select delicious juices. take the time for an unmistakable taste.

after they arrested liz golyar, of course, the next step is the actual preparation of the

trial. douglas county prosecutor brenda beadle took on the case. >> this was by far the most difficult case i've ever tried. most homicides are dark. this one was bizarre to the point where it would take some convincing to make somebody believe that it actually happened. there's no way that someone would let their dog die in a fire that they started. there's no way that someone would shoot themselves in the femur. >> liz golyar's defense attorney is james martin davis. >> james martin davis is somewhat of a legend in omaha, nebraska. a very, very well-known defense attorney. >> davis saw huge flaws in the case against liz golyar. >> not only was there no body, there was no crime scene, there was no murder weapon, there was no proof that she even died. we waived the jury trial to move it up so i could try this case

hopefully before they'd find a body. >> in waiving the jury trial, davis is requesting that the trial be presided over by a judge as the fact-finder instead of a jury. >> and we want to get it over with. they're scrambling now still to find the body, and they don't have a body. >> a few months before the trial, ryan avis and tony kava paid a visit to dave kroupa, just as they had many times before. >> and they turn around to leave, and kava kind of as a afterthought, said, hey, is there anything we missed? anything at all? >> the last few times we talked to him, he always said, no, he couldn't think of anything. >> for some reason, dave remembered he had a tablet that was in storage for the past couple years. >> it had been in a box for i don't know how long, a year and a half, probably. and i don't even know why i thought about it. >> when i examined the tablet, it had a micro sd card in it.

and that memory card, it looked blank. if you plugged it into your computer it would look like there was nothing there, but there was deleted information. >> that sd card, it turns out it had been in liz's phone. >> and it had thousands and thousands of deleted images that she thought were gone. but we were able to retrieve them. >> there were selfies that liz had taken. there was everything that you would normally have on your cell phone. but then i came to a photo that no one had seen before. it was reddish, and i wasn't sure what i was looking at first, but it turned out to be a human foot. a human foot with a tattoo. >> and the foot was decomposing, so this person was dead. >> so, you have to wonder, whose tattoo is this? what we discovered is that cari farver had that tattoo on her foot. >> we were able to figure out that chinese tattoo was the symbol for mother. >> mother. it was a role she loved, and of

course she loved her own mother. how perfectly fitting that the symbol of the thing most sacred to her would be the single most powerful evidence to emerge. >> this photo, it was shocking. >> it made me realize that liz golyar killed cari farver and she's taking photos of her body. >> it's really disturbing, almost like a keepsake or a trophy. i felt like our case was not the strongest before this, but once we had this, i felt confident. >> armed with this powerful new piece of evidence, prosecutors head to trial. >> this is a bizarre and twisted case of a fatal attraction. it's about an obsessive woman that would stop at nothing to that would stop at nothing to get what she wanted. >> and you're going to not hear a single eyewitness saying yeah, we saw her kill her. we saw her stab her. not a single eyewitness even saw

my client with the victim in this case. >> the prosecution truly did a masterful job laying out everything they had. >> of course, key to the prosecution, those messages sent over years and years of liz impersonating cari and pretending cari was alive to her mother and her son. those messages led cari's son, max, to reach out to his mom three years after she disappeared. he wrote, if this is really you, please come back. i want you to be at my graduation. >> it's so evil. it's so harsh for this family to see these and get hope. >> she's just diabolical and just cruel. it's mind blowing that someone was capable of doing all of these things over the time period that she did them, years. >> even liz's own attorney is struck by his client's cruelty. >> i would think to myself without disclosing my feelings to the client, i thought, "holy christ.

this is despicable." but it doesn't mean that they're first-degree, cold-blooded murderers. >> as for liz, she remained unfazed, even through the most graphic, damning testimony. >> she was an ice woman. never displayed any emotion. >> as for the motive, the prosecution doesn't have to prove that. but in this case, it seemed pretty obvious. >> liz golyar's motive was a man, and that man was david kroupa. >> i try to show, wait a minute, this guy's a nice guy, but he's not somebody that somebody would kill for. why would she kill cari farver? >> in her mind, she felt dave kroupa was worth all of this. so it wasn't necessarily just about dave. it's about the guy and about winning. >> despite the overwhelming evidence presented by the prosecution, there was no guarantee there was going to be a guilty verdict. >> the question was, would nancy and her family get justice?

>> how could this person do this to my daughter? and for what reason? for what earthly reason can you do this to anybody? >> and what is liz golyar's response to the accusations against her?

this is one of the few cases that went to trial with no body, no murder weapon, no witnesses. it's a hard case to prove, it's a hard case to make, and it's even harder to get a conviction. but the web liz golyar was weaving, well, she got caught in it. instead of being the spider, she became the insect. >> the judge found liz golyar guilty of first-degree murder. >> cari farver did not voluntarily disappear and drop off the face of the earth. very sadly, she was murdered. >> liz was sentenced to life in prison. >> i'm glad it's over with and she can't hurt anybody else anymore. >> i want liz to go away and never do this to anybody again. nancy and cari's son were foremost in my mind. they're, unfortunately, the ones that have to live with the repercussions.

>> since 2017, liz golyar has been at the nebraska correctional center for women. >> abc news reached out to liz golyar for an interview. she declined. but she has exchanged letters with author leslie rule. >> liz wants out of prison. she's claiming that the real killer is still out there. i will not stop fighting until i am set free and they find the right person. >> she's a psychopathic, toxic narcissist. it's all about her. >> as for dave, the years of being stalked and harassed and fooled by liz have had a big impact. >> i'm paranoid as hell. i really am. i don't trust anybody. i really don't. to me, doty, avis, kava --

they're all heroes. >> those guys, they mean the world to me. i can't thank them enough. they're my boys. >> we just kept thinking about nancy and max, and that's kind of what just kept driving us, is to get them answers. >> and it was important for us to clear cari's name. because she was accused of stalking, she was accused of harassment and she didn't do any of those things. that's not who she was. >> it's almost like murdering the victim twice. first she actually murders her as a human being, and then she's murdering her reputation and her memory. it's so fundamentally evil. there's no fate bad enough for her. >> cari was only 37 when she died. i would just want people to remember her as the fun-loving, talented, smart woman that she was.

and she loved her son. and she was a tremendous mother and she was a hard worker. if i could talk to cari right now, i'd say i love you. and i'm so glad that you were in my life. and i miss you terribly. the christmas rush becomes the covid rush in san francisco
