Pastor? Are you, sir? Thank you for coming out here. Inside this church in May, Texas, locals are gathering to mourn the tragic death of 25-year-old Chante Blanketship. Somewhere within this crowd is Chanty's killer, hiding in plain sight

and watching town folks pointing suspicions in all directions. Has she had problems with anybody? Who's this guy I'm calling? We used to have problems because he used to have problems, because he used to ride around with him and stuff. Whoever it is a pretty sick person and they're still out there somewhere. I think it's your boyfriend.

You know, she's a good-looking girl and that makes me a dirty old man. I think that's what we're said. As detectives exhaust every lead, the case eventually goes cold, leaving this small community questioning if any one of them might be the next victim.

Yet, for over a year, one unusual witness sits quietly on noticed, holding the answer detectives had been hunting for all along. He was so devious and smart. He just didn't know that that was going to be the thing that would finally catch him. The hatches that were showing on this is, man, you're off the freaking church. And here he is right in front of us.

And did I miss that? It's May 15th in the small town of May, Texas. Nearly 48 hours have passed since 25-year-old Shante Blankenship mysteriously vanished after going on her usual evening walk. Since then, church volunteers have searched tirelessly for any sign of her, until this Sunday morning, around 11 a.m., when one couple stumbles upon something. Well, not the location of the emergency? I have no idea where I'm at. I'm in the middle of nowhere. We were looking for Sontay Blankenship. Okay.

We found her. Okay. It's, uh, okay. It's, uh, okay? It's face. Real still for me, okay? I'm gonna try to pin your location. It's actually the, the, all the haunted house is what everybody calls it.

Is she okay? The community medical attention? There's her live. She's dead. When you're talking about you? Oh, oh, God. Okay. Yeah, I've got everybody head of that direction, okay?

Right away, the Brown County Sheriff's Office dispatches two patrol deputies to the caller's location, an abandoned farmhouse nearly 25 miles away. Once they arrive, they find Charlie and Jackie anxiously pacing outside, ready to go into detail about the gruesome discovery they had just made inside. We're just driving around looking for it. They did a, everybody met at three at the church to go look for her, and we were just driving around. Okay.

We looked at every creek and culvert we could find. The peel out marks were already here. Those over there, yeah. I've seen those tracks and they pulled in it. They didn't go on through. They would just stop. These aren't y'alls? Uh-uh.

No, this is the vehicle we're in. Are these over to the gate? Are those your shoe prints? Probably mine. Yeah, yeah. Okay, let's stay over here on the rocks and not walk around where there's any footprints. Don't let them leave there until I get out there, please.

10-4, they're waiting for everybody. To the deputies, this discovery immediately raises questions, The farmhouse sits miles out of town in an isolated location that many locals don't even know exists. So while they wait for additional officers to arrive, the deputy begins pressing for answers, trying to understand how this couple ended up here in the first place. How long did, I guess y'all called immediately when you found it? Which gate did y'all jump? I walked around the house, I didn't see nothing in there, and I went out to all the house building.

Do what? I walked around in the house. Uh-huh. didn't see nothing in there and went to all the outbuildings. Yeah. And I was coming back and that storm cellar there had a bunch of grass knocked down. So I run around and looked and there she is. She's upside down in there.

And she is beat. I got a daughter that age. She's naked as Jay Bird. All she got on is that white shirt she was wearing around in Friday when I was sate her. If I get my hand on them, so she's done that. I, I don't eat that right now, flashes. I took with them bastard. Oh, nobody.

She had a mentality of a nine-year. There's an old house back there. They apparently all met up at the church earlier at North Lake, and they were just coming out and driving around looking. She's in a cellar. You're serious? I said they were just out looking for places. Oh, that's that old gray house.

Yeah, I think so. They said they found hair laying out on the ground. They're like, what the heck is that? So they've already picked it up. It's like, I think cow hair or anything they were wandering around. I found her in the cellar. The gate's locked, so we'll have to cut it, but there's tire tracks that pull in there and then pull straight back out. Fresh trash?

Yeah, like today fresh. Indeed, these are very fresh marks, planting a terrifying thought in the deputy's minds that Chante's killer could be somewhere nearby, keeping a close eye on the area. Shortly afterward, more units begin arriving at the scene, including the crime scene photographer. And as the deputies prepare to head towards the body's location, they'll soon realize that whatever the couple told them is nothing compared to what they're about to see. Watch that wire. Yeah. It's on your gun. There you go.

You're good. All right, John. I'll step up here, I'll grab the camera and hold it. The brake works laying right on the other spot. I'm doing the car. Okay. So there's a little bracelet. right here on the other side of the gate you said yeah right over there in the

middle of that grass there's one of those wristbands those little rubber bands like this one it looks the way this grass is right here like someone's been through it recently or something knife laying on the ground I don't know it looks like it's been there a little while yeah it's been there a while but we'll go ahead and photograph it just in case I don't see any blood anywhere though I haven't seen drops mm-mm-mm-mm-hmm I wonder if someone pulled around of the back side of this house where it wasn't as obvious. Yeah, let's just follow the, we'll follow the dirt tracks. That grass disturbed. She doesn't have any pants on. Oh my goodness. Yeah. I want to say he said

he pulled this uh metal back. We need to find out I mean because you can see where there's a path right through here. Man this grass is still thick there's not there's not going to be any prints. This metal right here will need to process probably, or I would say. Here's another pink man right here, John. It's a legit homicide, it looks like. There's blood all on that rock right there. Once all your guys get out here, I'm sure they'll want to go through this building and make sure that there's not something inside here either.

Yeah. On the ground, halfway inside the cellar, lies Chante's deceased, and partially closed body, beaten so severely that she is almost unrecognizable. Beside her is a broken lawnmower blade stained with blood. Its condition and placement leave investigators with little doubt that they're looking at the murder weapon. All of it, the secluded location, the sheer brutality of the attack. And the way Shante's body is positioned leave deputies wondering, just what kind of a deranged person could have done this.

Following this, Chante's body is taken away for autopsy while officers clear the abandoned house. Inside, they find trash, empty alcohol bottles, and decay. But no blood or signs of a struggle. The next step for investigators is to speak with the remaining search volunteers, so they release the couple who found the body instructing them not to tell anyone about the discovery to avoid alerting the killer. But that's easier said than done, because for Brown County, discoveries like this carry a familiar weight, as the area has been no stranger to tragedy. In 1989, 13-year-old Amanda Goodman was abducted while walking home from school and murdered.

Seven years later, in 1996, 30-year-old Juan Laurels was found shot to death beside his burning car. Decades later, both cases remain unsolved. And even more recently, police recovered the remains of two missing residents in remote areas, areas of Brown County. So while investigators hope to keep details of Shanty's murder from spreading, in a town this small, news travels extremely fast, and investigators are about to learn that the hard way. And this is the church, North Lake. Because May, Texas is a deeply religious community, the search for Shantay has been organized through the local North Lake community church.

So investigators head there, but by the time they arrive, the situation has already changed, dramatically. A volunteer firefighter has just informed Chantay's family that her body has been found, putting deputies at a significant disadvantage. And as the deputy approaches the church, he's met with uneasy stairs from the crowd as he scans the room for any potential suspects. Okay. All right. I'm just looking. Oh, good. I'm just making observations. Oh, appreciate it. The crowd. You're not doing what, sir? Okay, that's fine.

Come on. Hey folks, could you have your attention just a minute? Folks, folks. Hello. Ladies, gentlemen. If you believe you have information that will assist in this investigation, I ask you don't discuss it with anybody else.

I don't want you to mix your notes with anybody else's notes or anybody else's observations. That's important because I want your recollections to be your own. Thank you very much for your cooperation. Pastor? Are you, sir? Okay. Doing well, sir.

Thank you for coming out here. You bet. While the community may not trust the deputy yet, they do trust Pastor Ron Keener. Having spent nearly five decades in ministry and years helping local charities, he knows this town inside and out, and having him on their side could prove invaluable to the investigation. As the deputy continues moving through the church, he notices people beginning to leave. With no legal authority to stop them, he urges Pastor Keener to help gather Shantay's family and those closest to her. But as detectives begin speaking with the people who knew Shantay best, one person quickly draws their attention, her boyfriend, John Adams.

And as they sit down with him, his behavior would be nothing like what you'd expect from a grieving boyfriend. My name's John Harper. I'm investigating Brackettyshire. I don't get trouble anymore. What was that mean? He told me and Frankie Salazar over one time. Now, no, now remember who you are. Yes, now I remember who you are. How long have you been with her?

Over three years, October 17. Okay. How was you, how did you and her get along? How we got along? Yeah. I mean, like, we, there was times I'm telling her life. We don't argue on me in life, but she's not capable of handling things. She has no problems

I mean like I try to, she has that habit of yelling and stuff and I just try sometimes I'd leave and then sometimes I could just talk her out

and be nice and she'd calm down but she just has I mean like I can say it she expressed herself different I mean like

sometimes it was like a wall but like she showed me to love you I mean despite just learning that Chante has been found dead, John doesn't ask a single question about what happened to her that night, leaving detectives to wonder if he somehow already knows. At this stage, deputies are looking for anyone who may have had a reason to harm Chanty. And without hesitation,

John would point investigators towards another man, someone who had just slipped out of the church the moment the deputy arrived. with anybody? There used to be this guy or this guy of calling. Guy where? Calling. Yeah.

What about Colin Smith? I mean, we used to have problems because she used to ride around with him and stuff and he used to just do stupid stuff and he like fire around drunk stuff like that and I didn't like that. And I didn't like that.

I should hang around with stuff but she pretty much and him got him to it one time because he came out to the house and she was a drunk I'm drunk there all I was drunk. I'm off of work. I mean, I'm like, what the hell?

And me and her stepdad were out there, and straightened out, and I never heard much out. He'd pretty much turned his nose and be. Okay. And then I've heard off my mom just goes over there, I mean. But it's just something I can't really be myself upset about. I mean, but I'm not foolish over. As John's interview comes to an end, deputies still aren't sure what to make of him.

Although he agreed to speak with him voluntarily and remains cooperative, detectives find his behavior oddly unconcerned. For now, John points investigators towards the only possible suspect he can think of. Colin Smith, a man deputies soon learn is no longer at the church. And as the church empties and the night comes to an end, detectives decide to wrap up the interviews and continue the investigation at first light. But when the community finally learns who the killer really is, they would be left speechless that someone they thought they could trust was

capable of such evil. I mean, we've got Hearst, been brutally murdered, and here he is right in front of us. How did I miss that? How did I miss it? The next morning, just as deputies prepare to head back into town, they receive a major Update from the forensic team. The initial autopsy results are in. Chante's cause of death is determined to be blunt-forced trauma to the head and neck.

Her injuries are consistent with the broken lawnmower blade found at the scene. She has no defensive wounds, while bruising on her arms suggests she had been dragged by the elbows. But investigators uncover something even more disturbing. Chante's body had been violated as she was dying, or even after her death. Male DNA is recovered, giving detectives their first concrete clue about the person they're looking for. And combined with the sheer brutality of the attack, investigators begin to suspect that this was not the killer's first time, and that other victims may still be hidden somewhere. At 10 a.m., deputies make their way into town and split up,

interviewing men throughout the area and collecting DNA samples in hopes of identifying the killer. they're dealing with a serial killer, they know they can't afford to waste time, as anyone could be a potential suspect. But the terrifying part is that they have no idea which of those encounters will be the one with the killer. I guess you know why I'm here. Well, I'm sure to ask a little bit with Sean Tate. Yes, sir?

What do you know about Shantay, sir? I lived here about four years and she walks up and down the streets every day. Something was said, and I'm not sure about the source because I was just assigned to come out something about you know that you had said that you get excited when you see her there might have been a comment made to say that you know she's a good looking girl and that makes me a dirty old man that I think that's what was said and I don't give it if you're a male and you ain't you're going to look at a young lady and say well damn she's pretty you know yeah I hear you somebody reported the dead body

hanging in there and they got on that gate dart that came open with them he told me she How long ago was that? Oh, that's been. Oh, okay. And you just seen her and waved to her. You didn't stop and talked to her. Yeah. I had to stop and talked to her in the past some.

She's a good little girl. You know, there's boys that would, you know, want to be with her. And John said that he was her boyfriend. She'd say, Collier was her boyfriend. You never know. After speaking with more than a dozen residents, detectives uncover a troubling reality. There is no shortage of men who knew Chante knew her routine and may have had the opportunity to harm her, meaning there are still too many possibilities and no clear suspect.

So in search of a breakthrough, the lead detective contacts Chanty's family and learns from her mother, Michelle, that the last person likely to have seen her before she disappeared was her closest friend, Caitlin. After getting Caitlin's address, detectives drive to her house, unaware that the woman they're about to meet, may hold the key to unraveling the entire case, because no one in this house knows Chante better than she does, or the three strange men who had recently entered her life. Caitlin, we're just trying to get as much information on this as we can. You just kind of tell me about Friday.

What was she talking about? She was talking about a whole bunch of different stuff. One thing that really got me was she told me her and Colin got back together. Her and her boyfriend John talked about how they broke up because she didn't like him. And then said that actually Colin told her, yeah, told her to meet him in the shed behind his house that night. Sorry. It's okay. Take your time. And then this guy, he drove by us in Bronco. It's white and red.

You know, when you see somebody you think is really creepy, you kind of get this. He looked kind of creepy and he waved at her and she was like, yeah, that's so-and-so. He really drips me out. Caitlin points to the three men who may have been involved in Chanty's disappearance. John, Colin, and a third man she can't remember, except for one detail, a red and white Ford Bronco. Once investigators locate the only matching vehicle registered in the area, the name comes back, as Bobby Sosa. So with three potential suspects now at the forefront of the investigation, John, Colin and Bobby, deputies split up and head out to each of their homes.

The first team makes their way to Bobby's property, and when officers arrive, they're immediately struck by something unusual, a strong odor coming from inside the trailer. Just to follow up on everything, I think, I mean, I don't think you're being, you know, misleading with us or anything. but just for us to cover anything since the vehicle's in the area. Do you mind if we go in your trailer and just make sure everything's okay and there's nobody in there? Yeah, you can check. There's nobody in there, but it's a mess. It's just more just to cover all of our bases.

Sure, I mean, I'm saying, no problem. Any guns in there or anything like that? No, no weapons. No weapons. Maybe a hot-in-law of view. That's fine. All right. How long you moved out here, man?

Oh, like you said, man. Oh, yeah. It's a mess. That's fine, man. Sure we've been in worse. I don't know. None of you got a hoarder around here. You know what?

We got plenty of those, man. Hoarders? Oh yeah. Yeah, that freezes look like it works good, man. It runs on propane. Do what? It runs on propane. Really?

As long as we're here real quick, your storage unit, is that cool? Appreciate it, man. You got it. You don't have a dog, get it? No. That smell? Yeah.

You come from the RV and he's done my things. I got to use that little thing there because I'm out of gas and go haul it to that place down the street. Oh really? You got a dump it in that and haul it down there? Yes, sir. Awesome, man. I'm sorry about this time. I'm trying to get everything good, epic. You're good, man. Despite the strong odor on the property which Bobby claims is gasoline, officers fail to find anything that connects him to Shantay's murder.

And while officers continue questioning Bobby, another team makes its way to Collins' house. At first, they're prepared to treat him like any other potential witness, but Collins' behavior and his refusal to cooperate would soon shoot him to the top of the suspect list. How you doing, sir? What's your name? Call up? You mind if I, you're going to ride with me up to the S.O.? And that-

Yeah, and I'll bring you... I gotta do it. Okay, you don't want to go with me? I mean, that's ridiculous that I'm even being looked at. She's got a boyfriend or a husband, John Adams. Mm-hmm. She's like infactuated me. should just walk up and down.

Did y'all have any type of physical relationship at all? Because some of the people we had talked to is that y'all had a relationship at one time. So never. What kind of relationship did she and the boyfriend have? He'd always pick her up and tell her to go get her home and detraved her like a dog. And there's a lot of people that are kind of looking at him. I mean, it's... Yeah, well, he's...

I mean, he's one of the people I need to... I'm going to have to interview. Are you working anywhere right now? I'd be lawn mowing out here. Okay. According to Colin, he never had any kind of relationship with Chantay, but detectives are buying it. And when the conversation turns to his job, Colin reveals he works in lawn care, giving him access to the same type of weapon detectives believe was used to murder Chanty.

But, seeing how defensive Colin is becoming, detectives decide to leave, asking him to come to the station the following day to provide a DNA sample and answer a few more questions. So now, with three key figures firmly on the investigator's radar, detectives back at the station begin taking a closer look at each of them, and what they uncover is peculiar, to say the least. John has prior burglary and assault charges and withheld critical details about his relationship with Chanty. Bobby has a previous assault charge against a woman, and was known to spend time near the area where Chanty's body was found. And Cullen, when While having no known criminal history has long been the subject of rumors about his violent temper.

And this is when detectives realized that any one of these men could be Chanty's killer, but figuring out which one will prove far more difficult than they expected. As the day comes to an end, rumors begin spreading throughout the community, and neighbors start keeping a watchful eye on one another. And with Chanty's funeral set for the following day, detectives will be doing the same, watching the crowd for a killer hiding in plain sight. I've always had this different part of me. It just wants nothing but destruction and evil. They wanted to kill somebody.

The following morning, medical examiners released Shante's body to her family for the funeral, but not before delivering one final unexpected update. Examiners have discovered unusual markings on Chanty's chest. Markings investigators cannot explain and believe may point to something ritualistic. To make matters even more unsettling, detectives realize Chanty had been murdered on Friday the 13th, a detail that only adds weight to this theory. But with no way of knowing whether the markings are significant or simply a coincidence, Investigators file the possibility away as the community prepares to say its final goodbye.

Around 11 a.m., nearly a hundred churchgoers begin gathering for Chante's funeral. The church is so crowded that some are forced to wait outside, and among them, patiently waiting, is Chanty's killer. Inside, Pastor Keener leads the service as the family and friends pay their final respects. The ceremony lasts for hours, though a handful of attendees quietly slip away, before it ends, including the man responsible for Chanty's death. A short time later, Chanty's coffin is carried to Pleasant Valley Cemetery, where she's finally laid to rest, and despite all their best efforts, police failed to recognize the killer. With the funeral over, detectives turn their attention back to the investigation.

They call all three key suspects and ask them to come to the station for questioning. Around 4 p.m., Bobby and John are first to a. arrived at the station, handing over their phones to be searched for potential evidence. And as detectives sit down with both men, it quickly becomes clear that they both have some explaining to do. Of course, I guess they told you when they got one of the phone, they get everything. They get pictures, they get text messages, they get phone calls, all that stuff. Right? Have you ever, you delete your text messages?

Yeah. But that was like long places and they don't know my phone out there. No, no, that's not what these text messages. these text messages that you deleted. And you know what I'm talking about, because you even told somebody, hey, my phone's clean. What are you worried about DNA so bad about? I don't know what I feel like that's all the way.

Well, she was like, I don't know why I'm so worried about giving DNA. What do you mean? She said you were texting her and asked her, well, they want my DNA, why do they want my DNA? I should, whatever. That's what the text message just said. It's not all the time thing. You mean like, I just might grow through friends or something like that.

I don't care. I don't care if you smoke. I don't care if you smell. Well, I don't care about that. I'm talking about what we got going on right now. And then we find your phone. And you knew we were fixing a look at everything. And then we find the message going,

because they can tell what's been deleted and one hadn't been deleted. And then they look and they like, deleted, deleted, deleted. If you did have certain. to do with this you need to let me know now i would have told you they work okay if i would have been around anything serious like that or do anything or anybody or do anybody that had anything to do with it or anybody like anything to help out you know i have i have nieces out there i have my sister up there and then we figure out who this person is i mean everything's kind of watching sheth kind of on a walk down because they're afraid of death right now yeah

Chonte told one of the girls that she was walking with that night that she was supposed to be coming back to meet Colin Smith. Yeah, that's what we've heard. Does that make you jealous if she's going to go over there and meet with Colin? Yeah, it doesn't make me jealous, but as I said, but it was still considering a way that I can't do anything about it. I mean, so it wouldn't make you mad if she was looking up with somebody else. But wouldn't make you mad. And wouldn't be not to stand this far away. I'd never do that, federal.

I don't really have much down around here. My dad's an American home. Just certain dollars. Well, that would make it even worse, though, because the one person that you care about, if she's sleeping around with somebody else, that would be the only connection you got out here, now just move on.

Upon speaking with both men, detectives notice they appear more nervous than before. That said, they also know both have prior run-ins with law enforcement and could simply be wary of being wrongly targeted. But one detail stands out. Only John appears to have deleted messages from his phone. By the end of both interrogations, only circumstantial evidence remains, so detectives release the men while instructing them to provide DNA samples. Shortly afterwards, Colin arrives at the station and, This time, things would take a very different turn.

Feeling as though he may be their strongest suspect yet, investigators immediately ask him to take a polygraph test. And as they sit down with him, it doesn't take long before Colin admits he hasn't been entirely honest with them. Whoever it is a pretty sick person and they're still out there somewhere, whether it's a guy or a girl. What do you think it's going to take to pass the test today? to pass the chest what do you think it's going to take the past

the palm? Honesty. Yeah, that's going to be I went on a question so I ate louder when she was with John she always had ace bandages and shit on

always looked like something was wrong with her sure, it was always telling me about him putting her hands on her are you all a pretty actual back then? I had it just a couple times I told them no the other day

just because I was scared as far as how she died what all do you know about how she died. This is the very first story we got, all right? It's sickening honestly. Sorry to the cousin. It's really sick to think of how many people out there

can gossiping and making their own stories up, you know what I mean? What do you think the person that killed her is feeling right now? I don't know. I think they're feeling guilty about it. Do you think that... I think it's your boyfriend doing. Only thing I can say is maybe Dawn did it out of like a crime of passion. Interestingly, Colin admits that he was, in fact, involved in an intimate relationship with Chanty,

but he insists that he has been truthful about everything else. However, that claim would soon be put to the test when the polygraph examination begins. And before long, something would happen that would cause Colin to abruptly end the interview. Hey, Colin, when we take this test, man, I'm starting to see some things in here, It's a little bit concerning to me. You know, you got to be sure to be still when we take the test. First off, secondly, you know, you got to keep everything the same. As far as when you're answering, there's a little bit of movement going on.

Okay, so just, you know, everything you do, just be yourself, okay? That's all we're asking. Colin, what do you think the best question to ask you is going to be today? Did I kill Sonté Blanketship? whether it be through strangulation, whether it be through blunt force, whether it be through whatever. Did you physically cause the death of Sonté is what I'm asking, okay? So your response is no.

What have you not been honest with me? I've been honest to you about everything. Okay. So why is it shown that you're being sensitive about this? I guess because I don't understand how it's what's showing. You're not even showing any reactions to those questions where I'm telling you to lie about it, where I'm telling you. Because he told me to stay his phone that I can and look at the board, so I'm just saying, yes,

and no. Yeah. And you know what? The reactions that we're showing on this is, man, you're off the freaking shirts. I'm telling you, I didn't do anything wrong, and I'd like to leave. And that's up to you. I can't force you to be here, but, you know, you're the one that's, uh, that needs to clear this thing of. I did come in here to clear it.

I gave DNA right off the bat, the very first one to test for DNA. and I came in here. This is a bunch of crap, man. Yeah, there's the door. I did what I was supposed to do. I was 100% cooperative. As Colin walks out of the room, detectives begin to believe

they may have found their killer. Because while Colin had been adamant that he had nothing to do with Chante's death, his polygraph results appear to tell a very different story. His elevated emotional responses reflected in changes to his breathing, heart rate, blood pressure, and perspiration suggest he may not have been entirely truthful when answering questions about Chanty's death.

That said, polygraph results aren't foolproof and aren't admissible in court as proof of guilt. DNA, however, is a very different story, and with DNA samples now collected from John, Colin, and Bobby, detectives believe the answer to who killed Chante must lie with one of them. The samples are sent to the Territ County Medical Examiner's Laboratory in Fort Worth, more than 100 miles away. And while detectives and the entire community wait for answers, the killer remains free to roam the streets. A month passes, and the DNA results finally arrive.

But when the DNA profile is entered to the National DNA Database, there are no matches. No match to John, Colin, or Bobby, and no matches to any known offenders in the area. Detectives are left with a troubling possibility. Perhaps their killer wasn't a local, but someone passing through town who had already disappeared for good. More than a year into the investigation, in October 2017, another investigator who had worked on Chante's case, Carlisle Gover, would make an incredible discovery. While watching a true crime show, Gover learns about an emerging technology known as DNA phenotyping, a technique that had successfully solved another cold case by generating a snapshot prediction

of what a person may look like using only their DNA. The next day, Gover rushes to tell the lead detective Scott Byrd. Within hours, the $4,000 needed for the testing is secured and the DNA is submitted. And as the image slowly begins to take shape, suspects would be a lot of the evidence. eliminated one by one until the true killer turns out to be someone no one ever expected. Yeah, by the time that the Blanketship case came along, we had a couple of cases that had used the phenotyping information to help solve their cases. Given the investigative capabilities that they had at that time, which were not DNA, he managed to avoid leaving any clues that got him caught. But he did leave DNA.

He just didn't know that that was going to be the thing that would finally catch him. This is Dr. Ellen Graytack, director of bioinformicematics at Parabon Nanolabs, the company behind the snapshot technology detectives used in the hunt for Shontate's killer. Within weeks of receiving the DNA evidence, Parabon's team analyzes the sample and generates a snapshot report predicting the unknown suspect's physical appearance. And as soon as it lands on Scott Bird's desk, he immediately recognizes, the man, 21-year-old Ryan Riggs. Years earlier, before entering law enforcement, Bird had taught Ryan in the fifth grade. When detectives dig deeper, they discover Ryan had been there

the entire time. He was a longtime family friend, attended Chantay's funeral, rode around with John calling out her name during search parties, and even hugged her parents at the wake. Detectives now know it was all an act, a years-long act that Ryan managed to maintain perfectly. On November 9th, officers head straight to his address, but instead, they're met by Ryan's parents who reveal that he has already fled. Within hours of the image being released, Ryan manages to slip away, and once again, police are back at square one, until the following evening at a church service when Ryan decides to do something completely unexpected. As I do for every service, God,

I stand in the parking lot, greeting people. And there was Ryan standing there with his mother, Michelle, and he said, I'm going to turn myself in tonight. He said, I murdered her. And I said, at that point, I'm going to step out in the parking lot and call Sheriff Hill. We're going to take you to the law enforcement center. He said, yes, sir, I want to confess to them.

To Detective Surprise, less than an hour ago, Ryan had unexpectedly shown up at a Wednesday night's service where he made a horrifying confession. He was responsible for murdering Chante. Not only that, he had just walked into the sheriff's office alongside Pastor Keener, saying he wants to turn himself in. Baffled by the situation, detectives bring Ryan into the interrogation room, and when they sit down with him, they let him speak. trying to determine whether this young man in front of them is truly the dangerous killer they've been hunting for nearly two years. So this happened on Friday the 13th. Tell me about that day. How'd you start that day out? I don't remember how I started the day. It was just like an average day to me up until I did what I did. I had stopped and asked her if she needed a right and she got in my truck. And then

Out of nowhere, I just put my left arm around her and began to strangle her. I went back to my truck and got a long marlard blade out of the back of my truck. And I went back to where she was and I beat her to death with it to make sure that she was dead. I've always had this, it's like this different part of me, that it just wants nothing but destruction and evil. And whenever I saw her that day, it's just it took over. So I was, I knew what I was trying to get. It wanted to kill somebody. Ryan's description of what he did to Chantay

perfectly matches the details from the crime scene, details that had never been made public. To detectives, it leaves little doubt that he is, in fact, the killer. If you could say something right now to Chanty, What would you say? That I'm sorry that I did what I did. And I, whatever I have coming towards me, I deserve. What do you think you deserve?

Death for sure. Anything else? No. All right, you were officially under arrest for Capitol order. With the charges laid bare, Ryan Riggs ultimately pleads guilty to the Capitol murder of Chonte. When news of Ryan's arrest reaches shot, Montes' mother, Michelle, she releases an emotional statement thanking the community for its support. Hey, everyone.

I don't know if everybody knows, but we caught him. We got him tonight for a capital murder trial. God has blessed us with him. And it breaks my heart because this man went to church with her and he's just a kid himself. I wanted everyone to know that we appreciate everything you all have done. In 2019, Ryan is ultimately sentenced to life in prison without the possibility of parole. But even with Ryan behind bars, the abandoned property where Chantay was found continues to haunt the town. The site became infamously known as the haunted house.

People regularly jumped the fence to explore the property, reopening old wounds for Chanty's family. Eventually, in 2025, both the house and the storm shelter were demolished in an effort to finally bring peace to the community. and allow it to move forward. And while this case left Texas, shaken by a killer hiding in plain sight, our next case takes us to Florida, where the warning signs were always there, but no one could do anything to stop what was coming. Or just signal 14 had a lengthy blood trail. We're going to several houses.

Yeah. Oh my god. Inside this family home, 21-year-old Dima Tower has just committed the most heinous crime imaginable imaginable against his own parents. North Court police storm it. I see bodies.
