>> we heard all this talk around town that jessie was dead. to know that the last moments she spent on this earth, she was in so much fear. it's not fair. if he's still out there, he could still be plotting, he could still be hunting. >> reporter: jesse gave her all. to everything she did. >> she was on a mission? >> her whole life. >> reporter: and then someone took it all away. >> i was like, jessie? nothing. then i kind of jiggled her a little bit. and then i knew. this is not good. >> what's the problem? >> my daughter won't wake up. >> reporter: she'd been murdered in her own bed, after coming home from a pool party. a party that hadn't been all fun

we wanted to talk to 'em. >> reporter: did something happen at that party? what was happening around this small town? >> i hear somebody running behind me, then i noticed he had a knife in his hand. >> reporter: someone was stalking young women. >> it was either i try to save myself, or let this guy do whatever he wants to me. >> reporter: his dreams were their nightmares. >> there were searches on serial killers. there were searches on bondage. >> reporter: could he be caught before he killed again? it, and now, i needed to go out and prove it. >> reporter: i'm lester holt, and this is "dateline." here's andrea canning with "obsession." ? >> reporter: she was a young woman who'd devoted her whole life to making music. an accomplished musician who played several instruments, acted. even wrote her own songs. ?

the world. >> that's the only friend i had that sang and did it all like the violin and piano. >> she had a really unique sound. >> yeah. >> reporter: so who could have predicted that on july 15th, 2013, the music, and a young girl's dreams would end so suddenly. >> we were in shock and disbelief. >> it was hard to understand and to come to grips with. >> oh my god, oh my god, oh my god. >> ma'am, stay on the line with me, we're going to get ems out for you. >> reporter: a small town faced with a mystery. with police asking, what was real and what was a performance? >> he's an actor. he's two different people. >> who is this guy? who does he think he is that he can go around doing this to women? >> reporter: ask anyone who knew jessie blodgett growing up in hartford, wisconsin, and they'll tell you she was happy, passionate, full of life. her dad, buck, says she had always been that way. >> did she have a happy childhood?

you're going to be able to count on one hand the ones you can find where she's not beaming and smiling. she was a really happy kid. >> reporter: jessie, an only child was the light of her parents' lives. their miracle baby. buck and joy blodgett thought they couldn't have children so they cherished their little girl that much more. >> we bonded from day one when that little purple head came out, and every day since. we talked about drugs, we talked about sex, there was nothin' off limits. >> reporter: and her mom says jessie's friends w >> they always seemed to hang out at our house. >> yeah. we did. >> she would, like, find any reason to throw a party. [ laughter ] yeah. >> reporter: ian, jackie and amelia were three of jessie's closest high school pals. >> we all just, like, kinda hit it off right away i guess. >> it's hard not to. i mean, she was a really contagious personality. >> reporter: but jessie also had a more serious side. one that loved to debate issues and fight for causes she believed in. >> jessie sounds a little like

>> she liked old people stuff. >> yeah, she did. i don't really know much high schoolers that are super activists about animal rights. >> she made herself well versed in just a lot of different opinions and viewpoints. ? >> reporter: jessie wanted to make a difference. that much was clear. but what made her happiest was sharing her gift. >> every time i went over to jessie's house, she would always be playing the piano. even though when i was trying to talk to her, she'd be like -- i'm like 'hello, jessie'. >> reporter: jessie's passion for music grew even stronger in college. in the summer after her freshman year, she teamed up with an old boyfriend and theater pal, dan. and together, they wrote this heartfelt song. ? ? >> we had a music room, he had a music room at his house. so he'd bring his guitar and

also won the title role in the local production of fiddler on the roof. jerry becker directed the show. >> did she just fully embrace it? >> she did. she enjoyed being the person who really opens the show, and sets the mood, sets the feeling. >> reporter: it was july 14th after the sunday matinee. jessie and the cast gathered for a pool party. >> we went out to a cast member's farm. he had a pool, and some llamas i left early with my family, and i remember her sitting there and i said goodnight, and thanked her for her performance. >> she came home around what time? >> it was late. 12:30, i believe. >> you were still awake? >> i waited up for her. i couldn't go to sleep until i heard that she was in the house. >> reporter: they chatted briefly and said good night. the next morning, jesse's mom popped into her daughter's room before work and saw jesse still fast asleep. >> nothing that you would ever think was odd when you left, i

>> no, no, and this was her first morning to sleep in, in a very long time. >> reporter: joy returned home for lunch and saw that jessie wasn't downstairs, ready for her afternoon violin lesson. >> i went to the top of the stairs. and i was like, jessie? nothing, so then i went in. i came around the bed. and -- and then i kind of jiggled her a little bit. and nothing. and then i knew this is not good. >> reporter: joy made a frantic call to 911. >> what's the problem? >> my daughter is blue. i went to wake her up and i just got home from, for lunch and she won't wake up. >> is she breathing? >> i don't think so, no. >> okay, you're trying to do cpr? >> i'm trying to just pump her chest. >> reporter: just hours before, she had seen her daughter sleeping peacefully. now joy, a chiropractor, was fighting to save jessie's life. >> your mother instincts were

yeah. i just kept thinking she fell asleep and stopped breathing on the pillow or something. >> reporter: as joy moved jessie to the floor to better perform cpr, first responders arrived. >> did you at that point start to feel her slip away, that hope was dwindling fast? >> i think i just was thinking they'll do it, they'll take her to the hospital. oh god, they can do all kinds of stuff, you know. >> reporter: but they never took ie it was too late. she was gone. a tragedy. and now a mystery. what happened to jessie blodgett? when we return, detectives hear something from jessie's mom they find interesting and troubling. when jessie got home that night from the party, she was upset. >> what's going on? oh, you know, the guys. >> reporter: what about the

>> reporter: joy blodgett had come home for lunch and discovered her 19-year-old da bed. jessie's father was at work. >> you had to call your husband. >> i wanted to let him know as soon as possible because i knew how much he loved his little girl. and i knew i had to get on the phone and tell him as soon as possible, but i didn't want to get him on the phone until i knew for sure. >> she said, "honey, honey, honey, it's jessie." then she busted out crying and i knew something was really, really wrong.

just tears. so i raced home. >> reporter: but when buck arrived home, police cars and a crime scene truck were already in the driveway. >> i went in the door through the yellow tape. and when i saw joy's eyes in the living room, then i knew that jess was gone. >> did you quickly ask how -- how did this happen? >> no. i -- my whole first thing was i wanted to see her. i wanted to touch her. i wanted to tell her goodbye. but they wout in jessie's room because police were in there, trying to figure out what had happened. detective richard thickens of the hartford police department was one of the first on the scene. he looked around, saw a typical teenager's messy bedroom. nothing strange there, but when he saw jessie's body it was clear to the detective that jessie didn't die of natural causes. >> the first thing i noticed was there was a very red mark running pretty much all the way

tell you what you were seeing? >> no, it was very apparent that this was a ligature mark at that point. >> reporter: jessie had been murdered -- strangled. but inside jessie's bedroom, there was no murder weapon. no sign of a struggle. except one thing did seem odd about jessie's bed. >> the covers were over the bed in a perfect manner. and a kid who had stuff strewn -- strewn all over the bed, there was nothing on the bed. >> it was very apparent that the scene had been changed. this is certainly a possibility of somebody trying to ensure of themselves behind. >> did they finally let you go upstairs when they finished, to say a proper goodbye? >> they released her room as a crime scene at the end of the day and brought her down. and after waiting all day to get my moment and say goodbye and tell her i love her, suddenly everybody's around watching me.

>> that is heartbreaking. >> yeah. >> reporter: having barely digested the news of their daughter's death and still in shock, buck and joy sat down with investigators to tell them everything they knew. there was no sign of forced entry to the house, but they explained, like most people in this quiet, safe town, they often left a door unlocked. >> this individual found that one door. the house wasn't ransacked. um, it looked to us that this person knew right where to go to find her. >> reporter: to the detective, it didn't seem random. it was clear jessie was targeted. one of buck's first thoughts, a crew of tree cutters that recently worked outside jessie's window. >> it made me wonder if they had had thoughts when they were in the trees, limbing our trees above her bedroom, and she was sleepin' in there. just wondered if they noticed that here's this teenage girl, sleeping, home alone when joy and i are at work while they're in our yard.

jessie was having at her part-time restaurant job. trouble with a co-worker. >> she had come home a couple of times and said that he was inappropriate with her. >> what was he doing that was inappropriate? >> he would often make sure that she had to rub against him as she passed him. >> that must make you nuts as a parent when you hear stories like that. >> when i first heard that i was almost out that door to go over and talk to him. >> reporter: the restaurant was it seemed possible that this co-worker jessie found creepy knew where she lived, had been watching the house. >> certainly we are gonna take any possibility. you don't wanna close any avenues of investigation at that point. >> reporter: then joy told the detectives something that really caught their attention. jessie had come home from that fiddler on the roof cast party, clearly upset. >> i said, what's going on? she said, oh, the guys, you know, they're always making

>> reporter: jessie told her mom two older men from the cast were flirting with her and it made her uncomfortable. one pulled her on his lap. the other told a dirty joke. at the time, joy thought the flirtations seemed harmless and her young daughter simply didn't know how to handle it. >> she didn't like men taking, you know, privileges on women. >> reporter: but perhaps the incidents were more serious than her mother thought. jessie wrote about them in her me." >> she was 19, and from what joy understood, these were men in their 40s. >> is that a bit of a red flag for you? >> can be. we wanted to talk to 'em. >> reporter: detective thickens could see the pretty, talented teenager could attract unwanted male attention. now he had to figure out if any of it had to do with jessie's murder. coming up -- a possible suspect.

within hours of her death word had spread. jessie's close friends, jackie and amelia, raced to the blodgett house. >> we drove up her driveway and her parents were standing outside. and they said, jessie is no longer with us anymore. >> was that when it became real for you? >> it was -- i don't know. it was -- it's like really shocking, i guess.

that anyone could ever feel. >> reporter: jessie's theater director, jerry becker, was also stunned, having just celebrated with jessie and the cast of fiddler on the roof the night before. >> the best way to describe it is simply surreal. that kind of thing doesn't happen here. >> and to someone like jessie. >> exactly. jessie was someone you could not imagine a bad thing happening to. >> reporter: finding jessie's killer became the police department's number one priority. attacked in her home where she should be safe and i think that it definitely did put people on edge. >> reporter: detectives talked with cast members from fiddler on the roof and heard again how jessie had been upset after the cast party. in particular, with one man named randy talley. >> we made contact with him and asked him to come in to speak to us. >> are you thinking that this could be the guy? >> he's significantly older. someone that was flirting with

her death, so he's certainly a person of interest. >> reporter: randy came in for questioning and admitted to joking around playfully with jessie at the party and swore there was nothing more to it. but part of randy's story didn't sit well with detective thickens. >> where had he been during the time of the crime? >> he was working. or was scheduled to work through a temp agency. he didn't actually go to work that day. >> so where was he then? >> he said he spent most of the day actually at his apartment by himself. >> did you just come right out with it? the murder of jessie? >> i asked him if he had any involvement in her death. he said no. >> reporter: but the detective wondered, was his story straight out of a script? >> he's an actor, and it's hard for me at that point to gauge if he's acting or being truthful. >> reporter: investigators issued a search warrant for his phone records. >> we were gonna verify where randy was and look at his alibi. was his cell phone anywhere near that house in this time period? jessie's friends quickly heard

cast member. >> what was being said about the -- the cast member? >> just that he was kind of creepy. and we thought it was him. i mean, who else could it have been? >> reporter: but the play's director, jerry becker, didn't believe it. he couldn't imagine randy being responsible for jessie's death. >> did you pick up the phone and call randy when he was going through this? >> yes. he was saddened by all this. >> how did that conversation leave you feeling? >> i was exceptionally confident at the end of that phone call that he was not involved in this in any way. >> reporter: and when the detective got his hands on randy's phone records, he began thinking the same thing. >> did his phone records tell you anything that was of significance? >> no. he hadn't been talking to her on the phone that we could see in this time period that we were looking at, and he hadn't been near the house. we haven't eliminated him but we're having to look at other options.

leads from jessie's parents. they interviewed the tree-trimmers who might have been peering into jessie's window. >> there was nothing of significance found as far as their possible involvement. >> reporter: and they tracked down the restaurant co-worker jessie had been upset with. >> he was actually out of the country, is our understanding, was at the time this would have happened. >> so case closed on that one? >> he's not gonna be involved. >> reporter: and remember, joy mentioned a second man from the cast parho the one she claimed told an inappropriate joke. turns out that guy was none other than jerry becker. >> i gotta believe it was sort of -- some misunderstanding that with regard to who jessie was talking about. >> so it was a surprise to you that she had brought up your name specifically? >> absolutely. >> did you have anything to hide about that night? >> no. my daughter and my son were there at the picnic with me. >> reporter: jerry told us he'd

about it. and detectives didn't think it sounded like much of a lead, and jerry never became a suspect. in fact, the investigation was going nowhere, leaving the town on edge. >> every time someone would come up behind me, i would jump, even if i knew they were coming up behind me. >> reporter: then, news of another crime heightened everyone's fears. >> it was an attack so brutal she had to get 15 stitches on her hand. >> reporter: it happened in a or on a young woman close to jessie's age, in a park less than 10 miles from her house. >> did you think that there was any possible connection to the park attack? >> they were too similar. they were too violent. they were against young women. they must be connected in some way or another. >> reporter: what had happened in that park, and could it lead detectives to jessie's killer? coming up --

>> you grabbed the knife with your bare hands? >> it was either i try to save myself or let this guy do whatever he wants to me. >> reporter: was someone stalking young women around this small town? town? someone's hacked all our technology. technology... say, have you seen all the amazing technology in geico's mobile app? mobile app? look. electronic id cards, emergency roadside service, i can even submit a claim. wow... yep, geico's mobile app works like a charm. geico. expect great savings and a whole lot more. a leading consumer testing publication recently tested the top laundry detergents. the winner - persil 2 in 1, didn't only beat tide... it beat every single detergent tested. boom. switch to persil proclean 2 in 1.

music was strangled in her own bed, her grief-stricken parents couldn't stop thinking about the >> that's such a dark place to go, to think about her last moments. >> doesn't get any darker than that. and i laid on her bed early on and held my breath long as i could, until -- longer than i've ever been able to in my life, trying to black out, to see how that was. which is nothing like what she went through. >> reporter: police thought she had been targeted. but now some of her friends wondered if her murderer was the same person who attacked a woman in a nearby park. >> when i found out about that,

head, like, who's next? you know? if he's still out there, he could still be plotting, he could still be hunting. >> i was like, who is this guy? >> reporter: this is melissa richards, the victim of that attack. it happened three days before jessie was killed. her courageous story of survival is amazing. >> you arrive at the park. and what's the first thing you see? >> a blue minivan. >> anything out of the ordinary? >> no. >> reporter: melissa richards and heg, walk in richfield park. and when they returned -- >> the guy was still parked in the car. and what i noticed was him looking out of the driver's side window. >> did it seem weird? >> i just thought he wanted his privacy. and then about here, i hear somebody running behind me. so i look back and go, oh, you scared me. then i noticed he had a knife in

coming towards me. >> reporter: before melissa could run, she was knocked to the ground, and her attacker pinned her down on her stomach. but melissa fought back and did something almost unthinkable. she grabbed the knife by the blade. >> you grabbed the knife with your bare hands? >> right. >> what -- what possessed you to do that? >> well, it was either i try to save myself, or let this guy do whatever he wants to me. >> reporter: with melissa resisting, the attacker apparently panicked and seemed to give up. >> he finally was just -- kinda got up off me. he was still holding onto the knife and he was like, can i just go? and i said no. >> reporter: a defiant melissa wanted her attacker to stay put and answer for his crime, but instead, he dropped the knife and fled. >> so he ended up running back to his car. i got in my car, and i got out of here as fast as i could. >> reporter: wounded and bloody,

stitches. there she was met by detective clausing of the washington county sheriff's department. >> this wasn't a robbery. he didn't say, give me your purse. this wasn't a dog knapping. he didn't say, give me your dog. this was a vicious personal attack on a stranger. >> reporter: melissa had never seen her attacker before, but lucky for investigators, she had an almost photographic memory. >> he was wearing glasses. he had blond shaggy hair. i said he's about 6'2", 210 pounds. >> did he look like a normal guy? >> uh-huh. yeah, especially with what he was wearing. just normal clothes from kohl's. >> reporter: melissa could even tell police the make and model of his van. >> she knew it was a blue dodge caravan, likely around 2000 to 2002. >> reporter: despite that great description, investigators could

jessie was murdered. and while some of jessie's friends had been speculating about a link, investigators disagreed. >> you're not linking the two crimes or -- or trying to force them -- >> no. >> -- to fit together? >> not at all. one's in a park with a knife, and the other one's in a private home with strangulation. >> reporter: so the two investigations remained separate and hartford police continued to look for new leads in jessie's case. what they knew. >> did you consider any of her friends as possible suspects? >> never. >> not one friend. >> never. >> reporter: the interviews with jessie blodgett's friends revealed nothing new. then detectives in the park case got a huge break. one that would change the course of both investigations. melissa's description of her attacker's van triggered the memory of a deputy who routinely

>> deputy meyer had approached us in the detective bureau and said several weeks ago i was in that park. there was a blue van parked in the exact same spot that you had described, parked the exact same way. >> reporter: at the time, the deputy thought the van seemed suspicious and ran its license plate, but he found nothing alarming and continued his patrol. now, his intuition was telling him the van was the same one he had no paper record of the plate, but in his squad car, the computer kept a log of old searches. and after hours of backtracking -- >> bingo? >> it wasn't a bingo, but it was very good. >> close? >> yeah, it was close. >> reporter: the van belonged to a laura and melvin bartelt. records showed that melvin was too old to be melissa's attacker, but detectives learned the bartelts had a 19-year-old son who matched melissa's

called that son's cell number, it rang somewhere that would surprise everyone. >> he answered. i introduced myself. i said i needed to speak with him. his name had come up in a incident. i asked him where he was. he told me he was at the blodgett house. and i said, where? >> reporter: coming up -- was this the break detectives so desperately needed, or just a strange coincidence? >> we were saying, no, not this kid. >> there's no way that he could continues. ues. proof of less joi. and clearer skin. this is my body of proof that i can fight psoriatic arthritis with humira. humira works by targeting and helping to block a specific source of inflammation that contributes to both joint and skin symptoms. it's proven to help relieve pain, stop further joint damage, and clear skin in many adults. humira is the number #1 prescribed biologic

she'd spotted at the scene. >> he was showing up in 15 minutes, so we were talking about how we were going to talk to him. >> reporter: their person of interest arrived, friendly and cooperative. >> my name is joel clausing. that's aaron walsh. >> nice to meet you. investigators noticed suspicious cuts and bruises on his body. >> what's that on your thumb? >> got stabbed with a screw at work. >> how? >> we have a, like a cart that we move stuff around on. >> he had a cut on his thumb. he had road rash on his leg. he had injuries which looked consistent with the injury someone might have had with attacking melissa richards.

skeptical about the work injury story. in fact, they weren't sure this 19-year-old even had a job. >> if we check with your employer, would they, would you still have your job? >> no. >> okay. that's what i thought. how long -- when did you lose your job? >> a while ago. >> it's the first time we had him in a lie. i picked up -- picked up my chair, moved it over next to him. we started a different phase of the interview. >> no more lies. it just makes things worse. >> reporter: so after the detective's warning, the suspect tried another story. this time, he claimed he'd cut his finger while cooking. >> nobody in their right mind would lie about cutting themselves if it happened at home cooking. okay? >> okay. >> what happened? just be honest. >> i have gone to the park before. i have been there. >> reporter: as the police continued to press the young man, he began to crack, and

correct, or your mom's van or your dad's? >> yes. >> and you went after that girl, right? >> yes. >> reporter: he admitted to going after melissa richards with a knife, and then offered a bizarre explanation for why he did it. >> i wanted to scare someone else because everyone else is so confident. i don't understand it, and i need someone to be l him under arrest, but were far from finished. the reason? remember what he told detectives when they reached him by phone. >> where were you at again? >> a house in hartford, jessie blodgett's house. >> reporter: that's right, the confessed attacker was also a friend of jessie's. >> is that the girl that just passed? >> yeah. we were visiting her parents. >> reporter: his name was daniel

and he was the same "dan" jessie had been writing this music with that summer. ? ? detective clausing called hartford police right away. they had a suspect for them in custody. jessie's parents refused to believe the news. >> we were saying, no, not this kid, no. >> he's a friend of ours and our daughter's. >> yeah, he's a little screwed up. he just got back from college. and he doesn't know what he's doing right now, blah, blah, blah. but we don't think it's dan. >> reporter: after all, daniel was more than jessie's friend. he was her first love in high school. and had never been in trouble. >> he had everything going for him. he was a top-notch student, straight a student. >> he got the lead role in most of the musicals. very talented. >> i was like, i like this kid, you know, just because, you know, he could make me laugh. and he came from a nice family. >> we said, it's not dan, he's a good kid. >> reporter: jessie's friends

cell phone, they were with him at the blodgett house grieving together. >> we were all crying, and our friend dan's -- his phone rang. and he was like, i got called into the police station for questioning. >> reporter: amelia and jackie were the ones who drove daniel to the police station that afternoon. they'd assumed it was just routine questioning about jessie. >> i was like, well, you know, dan, like, they might question you as a suspect. that's what they've been doing for all of her male friends. and he was like, oh, yeah, i didn't even think about that. >> reporter: now, even with dan under arrest for the park attack, they couldn't imagine their friend was capable of murder. >> i was thinking it was a mistake. like, yes, maybe dan did attack this girl in richfield, but there's no way that he could kill our friend. >> reporter: but the detective who'd just interrogated daniel thought the opposite. >> did you believe daniel could've killed jessie? >> yes. it was just a sense you got, a feeling you got.

from a killer? >> yes. >> reporter: detective thickens went to grill dan himself. >> i was hopeful that we might get more information that would advance our case. >> when was the last time you saw her? >> last week i think. >> reporter: daniel admitted to having romantic feelings for jessie, but swore through sobs he had nothing to do with the murder. >> what do you think happened to >> i have no idea. >> do you think it could have been accidental? >> i don't know why someone would do that to her. >> reporter: but detectives didn't believe him. and he fit the profile of the killer they were looking for. someone who knew jessie and her habits. >> she usually wouldn't get up before 11 or 12. >> all right. >> i would text her in the morning, ask if she wanted to

>> he knew where she was going to be, knew she didn't have a dog in the house, knew she didn't have siblings, knew where her parents were going to be. >> reporter: and as for his emotional denial, they thought it was an act. >> he was making these noises, gulping and -- and sobbing noises, as if he was crying. he didn't shed a tear during that entire time i talked to him. in my gut, i knew he had done it and now i needed to go out and prove it. >> reporter: coming up -- daniel faces a jury and jessie's family. >> i can't give you the answers

>> reporter: daniel bartelt had confessed to a violent attack against a woman in a park. but after police spoke with him, they realized he could also be guilty of something far worse. >> did you leave that interview having any doubt that dan was the killer? >> none whatsoever. >> reporter: daniel told investigators on the morning jessie was killed, he was in a park, reading a book. and when they checked the security cameras -- >> we found video that put him there. >> reporter: but that didn't mean daniel was innocent. detectives decided to search the park, combing through more than a dozen garbage bins, hoping to find anything that linked daniel to jessie's murder. and in one garbage can this cereal box full of ligatures.

jessie. plus a whole lot more. bloody sanitizing wipes, tape, shoe laces. >> i guess he didn't believe that we would have made the effort to go through the garbage to find anything. >> reporter: police sent the evidence for testing and forensics showed that both jessie and daniel's dna were on the ropes found in the park. detectives shared the incriminating discovery with jessie's parents. >> i had trouble getting it, that it was dan. the realist in me knew it was him. the other half of me was like, what happened to dan? >> reporter: daniel bartelt was officially charged with murder. buck and joy tried to wrap their heads around what happened to the funny teenager and had nothing but empathy for his parents. >> they didn't do this. they did nothing wrong. they provided a great environment for him, for his sister. they're good people. >> i can't say that he's totally

but something went very wrong. i don't know what. >> reporter: and they also felt sorry for randy talley, the cast member briefly rumored to be involved, now completely cleared. >> i felt bad. just more collateral damage from one person's evil choices. >> reporter: and though the dna evidence linking daniel to the murder seemed to give the d.a. a slam-dunk case, daniel pleaded not guilty. gary schmaus was his attorney. >> some people might say that there was overwhelming evidence against daniel. why go to trial? >> you go to trial when your client and -- and in this case dan -- denies having committed the crime. >> reporter: when daniel's trial began, the courtroom was full of conflicted hearts. supporters on both sides knew or cared for jessie and daniel. >> what was it like watching one friend being tried for killing another?

you're in the same room as the person that, you know, murdered your friend. it's crazy. >> it was the strangest mix of emotions. when he walked in from the backroom of the courtroom i wanted to hug him and make him feel better. i felt his humiliation and shame. i wanted to punch him. >> reporter: prosecutors said from the start, there was no easy explanation for why daniel >> why did he pick jessie, was he mad at jessie? no, he wasn't mad at jessie. he picked jessie because she was convenient. >> reporter: but the d.a. did say there was evidence that showed the seemingly sweet young man had been secretly obsessed with murder. on his computer police found disturbing internet searches. >> what does he do in the days and events leading up to this crime? he does a search for serial

of victims. >> reporter: their most alarming find was a violent, pornographic film with a plot eerily similar to how jessie was killed. prosecutors claim daniel used it as an instructional video. >> at some point in the movie he pulls out a binding, um, and places it around her neck, um, he then strangles her. >> there were searches on serial killers. there were searches on bondage -- >> did dan, then, who was big student -- was he also a serial killer in training? >> i think that's the potential. >> reporter: prosecutors showed the jury all the physical evidence. the dna, the tape, the wipes, the likely murder weapons that tied daniel to jessie's death. through it all, daniel sat quietly at the defense table, looking at no one, and showing little emotion. even when the d.a. presented

heard before. dna that the state argued showed he not only killed jessie but also raped her. >> daniel's dna was found under jessie's fingernails and inside her. that must have been one of the toughest pieces of evidence to combat in front of the jury. >> difficult. difficult. you know -- didn't have -- really an alternate explanation for that. and don't have one as i sit here >> reporter: in any case, daniel was never charged with rape. and for the murder? the defense rested without calling a single witness to the stand. the jury deliberated just three hours. >> we the jury find the defendant, daniel bartelt, guilty of first-degree intentional homicide as charged in the information. ladies and gentlemen, is this your verdict? >> it's not a good day for anybody. nobody won.

courtroom when he said this. >> dan, i forgive you. as i have every single day since we found out it was you. >> reporter: and in response to such unbelievable grace, daniel, looked straight at joy and buck and continued to deny his guilt. >> buck, joy, i can't give you the answers that you're looking for. i pray for you, for all of you. and i hope that -- i believe that someday i will be before a court that will know my conscience is clear. i love you and i'm so sorry for your loss. >> he's such a liar. he looked right in our face. i mean, with all this evidence that -- there's just no refuting

and then for him to still be looking at me saying this, i'm thinking, kid, do you honestly believe that i believe you with this? >> i think dan's a sociopath. he doesn't seem to have the -- the conscience. or if he does, he doesn't care. >> reporter: buck and joy have accepted they may never hear the truth from daniel or know why he turned so violent. but the blodgetts are doing their best to move on. for buck, jessie's untouched room is a constant comfort while for joy it's a painful reminder. >> are you gonna move? >> i'm staying here because that's what he wants. but i would move tomorrow. >> do you feel that if -- if you leave you're leaving jessie? >> not exactly. i feel like she's with me everywhere. and maybe we should talk again 'cause i didn't know you still felt so much that way.

without the chance of parole. for the attack on melissa richards, he was sentenced to five more years. >> melissa's our hero. if it wasn't for her, they wouldn't have caught him. we are forever indebted and thankful to her for that. >> the police and the blodgetts commend you and do feel that other women could have been murdered if it wasn't for you. >> i tried to help as much as i could. i just wanted to help 'em out. i don't know. i tried. ? ? >> reporter: jessie's parents have started an educational campaign in their daughter's honor, called, "love is greater than hate." >> i'm doing it for the millions of people who will be jessie. if not murdered, sexually assaulted and have their lives changed forever because of it. >> reporter: those who loved jessie, say her zest for life changed them for the better and still lives on through her music and her spirit. >> we started thinking

because of her. >> have the tables turned? you were always the one proud of her. and now, do you feel she's the one proud of you? >> i feel like now she's the one lifting me up and encouraging me through life, where it used to be the other way around. ? there's nothing i wouldn't do ? ? i'll be here i'll be here for you ? >> that's all for this edition i'm lester holt. thanks for joining us. a cash reward up for grabs after a gun theft in thornton. >> it's not safe to be on a major roadway out of a vehicle. >> a texas woman shows us what not to do on a busy highway.
