Talking Dateline: Heartless

from Dateline NBC Hosted by NBC News

Keith Morrison sits down with Josh Mankiewicz to discuss his latest episode, “Heartless.” When 53-year-old Talina Galloway went missing from her Oklahoma home in March 2020, her friends knew something was awry. Police began looking into her disappearance, as did a group of online sleuths who called themselves “Talina’s Army.” Eventually, the investigation led police to Talina’s body and to her killer, who was all too close to home. Josh and Keith discuss the ways armchair detectives can help and hurt investigations, as well as the sci-fi subculture that formed a major part of Talina’s life. Then, Josh answers your questions from social media. Listen to the full episode of “Heartless”: https://swap.fm/l/dl_heartless Have a question for Talking Dateline?

Learn more at aboutamazon.ca Hello everybody, I'm Keith Morrison and this is Talking Dateline. Today I'm joined by Josh Mcawitts, who discusses episode which is called Heartless.

Interesting title for this one. It's about the disappearance of a woman in rural Oklahoma, the armchair detectives that brought attention to her case, and the killer who is too close to home. But before we get into all of that, if you haven't listened to the episode yet, you can find it right below this one or stream it right now on Peacock. And then come back and we'll talk. We'll have more from Josh's interview with Tylena's killer and later your questions from social media.

Alright, let's talk Dateline. So this was an interesting way to get into a story. Josh Mcawitts, you got it through our digital team. When you were doing the missing in America? Yes, I got a call several years ago when Tylena was missing, before she'd been found, by a friend of mine who knew Tylena I think through through work.

And she said this one I know is suddenly missing and nobody can find her. And maybe this is something that you guys could work on. So I said it to Veronica who's in our Dateline episode who runs the missing in America franchise for us. And so we did one of the first stories on that case. We were sort of one of the first places where that where Tylena's case gets a national play.

Now, I mean, the first to admit that I don't think that our missing in America thing did anything except generate a lot of tips. I do not think it played any role in solving the case, but it did sort of begin to get the case out there. Was that what prompted the armchair detectives on social media to get involved? Well, it's impossible to say sort of what prompts, I mean, what got everybody interested in the Karen Reed case? What got everybody interested in the Lindsay Clancy case?

There's a sort of a spot or a sort of a match strikes on the internet. And suddenly there's this wildfire of interest. And there was some of that in the case of Tylena Galloway. You know, people who had never heard her name before, didn't know who she was, had never been to Oklahoma. Suddenly we're super invested in finding out where she was.

And we sort of talked to one of the leaders of that group, Jess. Yeah. It's very interesting about these kinds of groups that form sometimes spontaneously, sometimes intentionally. The police occasionally like to work with them. These police officers didn't seem necessarily all enthusiastic.

They were sort of ahead of them most of the time, I think. It's hard to say. I mean, obviously I wasn't privy to every conversation or any of the conversations between the sort of the amateur sleuths and the sheriff's investigators who were working this case. Those investigators, the sheriff's department, they solved it. They got to the bottom of it.

And, you know, were they helped along at some point by the amateur sleuths? Maybe. But this is certainly mostly almost all their work. You know, the problem, as they say in this episode, is that when you get all these tips from elsewhere, generated by people on the internet who unquestionably sort of, you know, mean well. And in some cases come up with legitimate, interesting, worthy to explore avenues of investigation.

That could slow things down, particularly if it's an investigator, you already think you know what's going on. But those tips can't be discounted. I mean, our missing in America story generated a tip that that Toleena had been seen here in the distant suburbs of Los Angeles. Well, not true, but they have to check it out. And so that I think investigators feel like that kind of thing slows them down.

But there's no question that like sometimes it leads to something. I think it definitely slows them down in many cases. I've only encountered one, which was a case where the person was missing. She was already dead and they're trying to figure out who she was. It was missing.

It was a Jane Doe case. And in that case, the detectives actively sought out and were happy to accept the help of this online group of sleuths. And it made a big difference. But again, if somebody is missing, they're trying to solve a murder as a different situation. Well, the one I always come back to was the Kristen Smart case in which, you know, Chris Lambert, who was a, you know, podcaster, not an investigator, didn't know the smart family, never investigated, you know, crimes or anything like that.

Sort of took it upon himself to begin investigating this and then generated a tremendous amount of information that kind of helped kickstart the case. And there's other cases around the country where sort of amateur sleuths or podcasters, you know, made a big deal. And there's also cases in which amateurs lose and, you know, sort of gotten away. Generally law enforcement happy to have tips. I think there's a point at which they sort of fill in enough to stay in your lane.

It's also a change from the way it was, you know, when I started, certainly was just about seven eons ago, but where the officers did not want anybody interfering. They did want anybody even talking to them about it. They're doing their own investigation and stay out of it, please. Cops were working with oil lamps weren't they when you started? I think that's about right.

Driving driving around in their horseless carriages. I don't think people, I don't think people try to solve crimes at home, whether they're disappearances or murders. I don't think that's going away. I think the internet makes that much more possible than it was just a few years ago. And it makes it inevitable and it can create a community of sort of like minded people who want to get to the bottom of it, which is exactly what happened in this case, and just a tremendous amount of work.

And, you know, I mean, at one point, investigators told her to sort of slow down because Corey, their suspect, was reading the Where's Tylina Justice for Tylina web page and thinking, I'm under suspicion, which from those people, she absolutely was. I think the cops wanted her to feel like, no, no, you're not under suspicion. You're, you're, it's still safe to talk with us. And so they sort of asked, Jessica, like, can you, can you just hold down a little bit? And the cops really clearly wanted to keep Corey talking because every time they spoke with her, they were, the shares of us were learning a little bit more.

Her past is pretty fascinating. What kind of character emerged in your mind from that investigation of her past? Corey's past kind of murky, not a whole lot known in detail about sort of where she came from and what led to that. But you spoke to her ex-husband. Yes.

His story. The story, you know, police do about what they should be looking for. Well, yeah, I mean, right. That's, you know, that's not a story you tell somebody sort of on the story of the moment. I mean, Alec, her ex-husband calls police and he hears Tylina's missing.

And he's like, look, couple things. One, you're not looking for a live person or a body. You're looking for body parts. And second, you're looking for ricin, which is this, I mean, I don't know if exotic is the right word for it, but highly unusual out of the mainstream poison that is used in, you know, like by terrorists and assassinations and stuff. And his story is Corey was making ricin when they lived together in Wisconsin and she told him that she broke into the neighbor's house and spread rice and to kill them.

And she said, I'm making ricin to deal with our enemies. She said, that's how he quotes her. Now, the interesting thing about this is that the people living next door to Corey and Alec in Wisconsin hardly meet the standard of being an enemy. I mean, I'm not sure they actually had any dispute with them. Corey may have believed that they were the source of the township sort of saying you have too many animals.

You have to do something about them. You know, you're making a lot of noise and they smell bad and neighbors are complaining. But the zeitlers who I spoke with at length, they say, no, that wasn't us. That was one of the other neighbors who made that. Everybody was upset about that.

This really is killing an ant with a cannon. I mean, you get in a pretty strong response. Yeah, you get in a pretty small dispute with your neighbors. And the next thing you know, you're spreading a poison that's used, you know, to assassinate foreign leaders and things. That's kind of crazy.

Now, by now, six years have passed. It's pretty clear the zeitlers didn't suffer any ill effects from that rice. And because it turns out it was incompetent. Thank you for that. I mean, can you imagine?

But because by the time that everybody realizes that was rice and it's like six years later and Mrs. Eager can barely find any of it still in her house, which is a good thing because they would have been killed very quickly if the rice had been made properly. And of course, the recipe for rice is on was found on Corey's computer, one of the search warrants. But that's just a coincidence. Of course, it's a coincidence because everybody looks for things like rice and then it's normal.

And when we come back, we are going to have a listen to a bit of a conversation that Josh had with Corey. You'll get an impression of just what this woman is like. At Capital One, we don't just use technology. We architect it. Our teams have true end-to-end product ownership, shipping distributed systems that handle high concurrency at scale.

No single server bottlenecks engineered beyond legacy downtime and operating right here in downtown Toronto. That's technology at Capital One. Search technology at Capital One Canada. Off the coast of Newfoundland, something lurks beneath the surface. Below is a new six-episode thriller series.

Fisherman Calvin Penny, played by Josh Hartnett, is already burdened by his father's mysterious death when a sea creature begins terrorizing his hometown, putting his son Wade, played by Charlie Heaton, and the rest of his family in danger. Partnering with a visiting marine researcher, Mackenzie Davis, Calvin must protect what's left of his family and uncover the area's long-buried secrets. Watch below, streaming only on Netflix. Learn more at aboutamazon.ca It's a

subculture. People might not understand. Well, I mean, normally homicide investigations have a nasty habit of pulling back the covers on everybody's secrets. Whether or not they are related to the crime itself. No social murder investigation.

Right. You're having an affair. You're embezzling money. You're a tax evader. Like, all this stuff is going to come out because investigators don't know which is going to be the part that actually plays into this. However, very quickly, it became clear to them that they weren't getting any

leads in that. Like, whatever was going on, it didn't really directly have anything to do with Tylina's lifestyle, which she and her husband had practiced, and then he had died of a stroke a couple of years earlier. So, did it involve other people who were in that lifestyle? Possibly. I mean, they certainly looked at that guy Marty, also known as Wolfie.

Corin points at him as the main suspect. Investigators clearly looked pretty hard at him. Here's why they thought that Marty Wolfie was not a good suspect. He was in terrible physical shape. You can see that in the interrogation video.

He had a drug problem. He died of an overdose. It's doubtful to investigators anyway, and to others involved in this, that he would have had the physical strength to move Tylina around in that freezer that he would have been able to physically inflict the blows on her. But also, you know, when investigators are talking with witnesses or people who are maybe persons of interest, they're watching very carefully to see how they say it, what they admit to, what they hold back. And in that part of the investigation, Marty came across as truthful, even admitting some things he'd done that maybe were not completely legal, like breaking up at Tylina's house and taking a chainsaw, which he later ended up confessing to and bringing back. Marty came across to investigators

as truthful and helpful. Corrie came across to investigators as shaving the truth, changing her story, not telling the truth all the time, and also lying about little things, which always makes investigators sort of sit up a little more in the saddle. Did it surprise you that she was prepared to talk to them as much as she was and that she was prepared to sit down and be with you? You know, when you talk with Corrie, like when you see Corrie in this story early on, talking about her friend Tylina, it was missing. Like her affect is not that of a guilty person who has been caught. She is exactly talking the way an innocent person would react if a friend of

theirs were missing, which is sort of what made that interview work and why we put it sort of all the way through. You also got the impression again in the first hour particularly that you'd be hearing more about the relationship between Tylina and Corrie and that there was, you know, in the aftermath of their marriages, they got together as two women and there was some sort of romantic attachment which might get stronger. So I want to play a little bit of your Q&A with her. When you asked her about that very question, I thought that was pretty interesting stuff. Here it is.

Two of you were just friends and roommates. Just friends. There was no other kind of romantic relationship. None ever whatsoever. In fact, when Tylina's husband died, she really disavowed interest for a long time in anything romantic or sexual. And when I finished my relationship

with my ex, I took vows of celibacy. I was really not interested in any future relationship either. It's been suggested that you wanted more out of that relationship than Tylina did. Which is, which is, I guess it's not unusual or unfounded for these people to think that. Given Tylina's lifestyle. Not true. No, not on any level. There are people out there in the community

who knew that there was nothing between us other than a very strong platonic friendship. Right. I'm not asking whether there was anything between you. I wouldn't be afraid to admit if there was, but there was nothing sexual between us. And you were not interested in that? Not interested at all.

There were a couple of different schools of thought about motive in this case. And that plays into one of them. There are people involved in this who think Corey wanted some kind of relationship with Tylina. I will say that beyond the anecdotal musings of people who are Tylina's friends, we have no reason to believe that is true. We have no reason to doubt Corey's word on that particular issue. Second, there are people who believe that this

was about money because Tylina, if she got Tylina out of the way, she'd be able to use her credit cards and get to her bank account. And then there was all this stuff in the house that she could sell. Corey was very accomplished at selling stuff online. And then there are, there's a school of thought, which includes the prosecutor in this case, that there was some kind of fight between the two of them. And Tylina was going to kick Corey out of the house. And Corey didn't really have anywhere to

go. And so she killed Tylina sort of out of anger and to prevent herself from being put out of the industry. I'm not pretending to know which one of those it was. But I will say that the Corey wanted more of a relationship than Tylina did appears to be the one with the sort of least foundation. But it's interesting that there'd be so many possible motives and yet they didn't really zero in on anything and say, that's it. That's why this happened. And it's a terrible thing that happened.

You've got to be, you naturally want to feel as if there was some very strong motive behind it. Well, you do. And all of us, I suspect you as well sort of tend to approach murder cases, looking for a motive that we can sort of understand within our own ethical framework, right? Like, why would somebody do that? Like, because it doesn't make any sense to me that it was for this reason or that reason. Right? So, you know, that's usually a mistake because

the only frame of reference that matters in a murder is the one of the murderer. It doesn't matter what you and I would do in that situation. It matters what they would do in that situation. Yeah. You know, and some people, you know, had sort of lived lives without consequence.

You know, if you've gotten away with a lot of things in the past, even if it's not murder, you might think, well, I can get away with this too. You know, the verdict in Wisconsin suggests that Corey, you know, believed that she had already gotten away with attempted murder. And so, you know, maybe there's nothing to fear. And it may very well be that she sort of thought, you know, these rural sheriff's investigators and this DA that actually represents multiple counties, they're not going to figure this out. Well, that's a pretty common thought.

Yeah. The criminal who thinks that they're a little smarter than the people who are smarter than anyone else. Yes. Yeah. Well, you know, this case never made it to a courtroom. Corey,

you know, Corey pled no contest. Yeah. Original first degree murder tries was reduced first degree manslaughter. I think Corey's defense team to a pretty good job here. I don't think there's any question about that. I mean, her attorney, Rachel, that's got a person you would hire if you were in

real trouble. No question about that. This is a circumstantial case. Now, as we've discussed before, circumstantial evidence can frequently be the strongest evidence there is, right? I need you carefully down a nice road to order inevitable conclusion. Right. So there was a circumstantial case,

but I thought a pretty good one. Corey pled no contest. This is different from what you heard many times here on Dateline and elsewhere, which is something called an Alfred play in which in an Alfred play, you acknowledge that the evidence will convict you. But you don't admit that you did it. Right. But would you do it without an admission of guilt? And in this case, you also don't admit

guilt, but you're not admitting that the evidence will convict you. You're just saying we do not contest the charges. In the end, it doesn't make very much difference to her because she's gone to prison for, you know, effectively the rest of her life. I mean, even if you only serve a small portion of that, she's not a spring chicken, particularly. She's not a young woman, right? Yeah. Well, we are going to

take a break and when we come back, we will address some of your questions from social media or Mr. McAvitt's era.

something lurks beneath the surface. Below is a new six-episode thriller series.

Learn more at about amazon.ca Well hello everybody and we're back and Josh now is going to answer your questions about this episode. So let's do it. Josh, there are several questions. It seems to be a popular episode.

I can't imagine why. You actually did hear that. John Kavanaugh on Facebook asks, what's the accent on Rachel? Fellina's best friend? She's from Great Britain. Sounds good. She said that

a lot of people in that part of Oklahoma couldn't place her accent. Yeah. S. Floyd on X says, on guessing authorities were to dig deeper into Corey's past, they might find other instances similar to this one. Under pressure, she doesn't act like a beginner.

Well, if I may call you that, that is something that both Fellina's friends and law enforcement thought about because there is kind of a zero to 60 element of this. If you believe in Corey's guilt, and she now has two separate verdicts, then you've got to believe that she never committed any crimes before making an exotic homemade poison and trying to kill the zieglers and then beating Fellina to death as she slept. Although she has not been charged with anything else, and I am unaware of her even being investigated for anything else. So I mean, at the moment, this is all there is. It is not the answer. You say zero to 60, though. You're right. It's

it does make people wonder. Is the correct answer to that? The tip in 2026 on X asks, why isn't this person wearing prison garb in interview with Josh? Because although she was encusted at the time, they usually have access to regular clothing because of court appearances. So that wardrobe is usually there. Sometimes their attorneys supply them with clothing,

which I think might have happened in this case. Let's go to CMO and X who asks, did anyone check market system for writing? They did, and the results were negative. Also, they checked Alina and the results were negative. Marty's death officially went down as a drug overdose, and given his history and his physical condition, that is 100% plausible.

Gotcha. Patricia and Watkins on Facebook asks, I would like to know who the other person was. This is a very good question. Who the other person was seen dumping the freezer, the former private detective said she saw two people on the truck. This is a very interesting part of the story. Janilin, the private detective, the ex-private detective,

is an observant person. And her story certainly rang true, I thought. Law enforcement was not quite as persuaded as maybe you were a Patricia or maybe I was. Law enforcement thinks there was no second person that she just got it wrong. Or that she heard somebody talking on a cell phone, and mistook that for a conversation between two people who were at the scene.

There's also a theory, this is not a law enforcement theory, but there's also a theory put forth by some people, Talina's friends and other people who have looked at the case, that one of those people that she saw was Corey. And the other one was some homeless person who maybe was hired for 50 bucks to help move this freezer, but who did not know what it was they were moving or why or what was inside. But the short answer to your question is law enforcement is not convinced that there was a second person, and if there was a second person that person has never been located or identified. And by the way, Corey argues that of course neither one of those people is her, that that's Marty and somebody else, somebody that Marty brought along to do it. Marty's description I think doesn't match with what Jynil and saw. But again, you know, I mean, I witnessed the

counts are not always 100% reliable. Well, I believe you've answered all the questions, Josh. I mean, you can answer some more except I have none for you. Oh, that's too bad. I like it when you ask me questions. That's it for talking Dateline this week. Remember, if you have questions about
