Hi, everyone. I'm Blaine Alexander, and today we are talking Dateline. I am here with the one-and-only Keith Morrison to talk about his episode Under a Full Moon. Hi, Keith. Hi, One-and-only, Blaine. How are you? I say that every time, don't I? It always bears repeating. You know what? It doesn't make me feel bad when you say that. Well, then we'll keep doing it. I love it. Well, if you haven't seen this episode yet, you can find it in the day. Dateline podcast feed, so go there and listen to it and then come right back here. Just a quick recap, in September of 2012, George TFA found his wife Shana beaten to death at home. Investigators wondered if someone had followed her there from her job as a cocktail waitress on the Las Vegas strip.

But later they realized that the killer was someone much closer to home, and someone even closer still, I'd put him up to it. For this talking dateline, we have an extra clip from Keats' interview with George T. TFA's sister. Then Keith and I will answer some of your questions from social media. So, Keith, let's do it. Let's talk Dateline. Let's do it. Let's talk about the strip. I found it interesting that this entire thing took place with the Las Vegas strip there, kind of as the background character, if you will. I mean, Vegas is always a spicy place, an interesting place. And so what was it like doing this story in such a place as Las Vegas versus some of the other places that we go to? I'm glad you asked that question.

This is one of the things I enjoyed about doing it. And because in the many stories that I have done, and we have done in and around Las Vegas, which is a giving place for Dateline over the years. You know, from the outside looking in, tourists going to Las Vegas, people going to gamble there, it's a certain kind of place. Maybe it's exciting.

Maybe it seems, you know, kind of something you do and leave there and don't tell your friends about. But there is a kind of a work-a-day world of Las Vegas where, you know, good, hard-working, honest people go into work every day, to work as cocktail waitresses, to work as firemen, to work as, you know, to make the city run. You know, Vegas is a, in many ways, a working-class city. And then it's just got this very colorful strip down the middle of it with some colorful jobs associated with that well i mean the thing about

Vegas for many of us who go there there's a lot of money to be spent uh but for people who who work there there's a lot of money to be made i mean i think this episode really showed a lot of people how lucrative uh being a cocktail waitress in las Vegas can be right yeah maybe you have some one kind of an idea of what a cocktail waitress um would be like the sort of work that he or she would do or the kind of money he or she would make but then you just throw that out the window when you go to Las Vegas. Yeah, you're making money.

I mean, based on that, it certainly is reasonable to assume that in this episode that this could have very easily been, you know, what people would call a robbery gone wrong, that people know, okay, she's a cocktail waitress, she's really good at it, she's got a lot of tips,

it makes sense to follow her and try and take her money. Well, your first thought, if you're investigating it, I would think, would be here is a very attractive woman in the middle of the night, heading home from work. So there's the possibility that somebody was chasing her for that for

some sort of sexual encounter with her. There's a possibility somebody was trying to, you know, chasing her for her tips, which, you know, she would carry with her on the way home or might be carrying with her on the way home. So yes, that's your first go-to place. Let's talk about this investigation. I mean, the first big surprise for me was that her house had been burglarized weeks earlier and it was very creepy to hear what was taken from her house too well yes but um you know as we've covered these kinds of stories that is not that unusual that sort of material is and it's you it is a creepy thing and it also indicates that there's some danger in the vicinity so it certainly is understandable we'd want to follow that up for sure and chase it down as much as they could but it

really just didn't go anywhere, anywhere useful anyway. I mean, you talked about the fact that they thought maybe it was some kids in the area. They were questioning. They were looking at them. How long did they go down that road before they said, okay, this isn't going anywhere? Let's look somewhere else. Well, not that long, really. There were a lot of things that they looked into that just didn't go anywhere.

It was just maybe in this case, as the police are investigating and chasing down leads and looking at this possibility and that possibility, the fact that they didn't, look at George was a bit of a failure of the imagination because, you know, like you, they recognized that this was a twofold. This was an upstanding person who had lived an upstanding life. There were no indications that he would do any such thing. And besides which, he was on a long shift at the fire department all night long and simply could not have committed that crime. So he had an absolute ironclad alibi. I think that alibi. I think that alibi, I think that alibi that when as i was watching this just just kind of going in blind that was what sealed it for me

sure it was working overnight at the fire station you know i mean firefighters aren't going to lie on his behalf right you would think um he goes out on calls that's something that you know you lock that down okay he was there he couldn't have done this let's look somewhere else uh i was fooled george had me fooled but understandably so because george was the kind of person who uh you know every guy probably who grows up thinking I ought to be. If I were a better person, I'd be like George. George was the All-American. George was handsome. George was, you know, fun to talk to. George was good to be with. George was kind to all kinds of people. He had an opportunity to be a wealthy finance guy, and instead he chose to become a fireman and an EMT because he wanted to help people. And that was

just George. He was like that to the whole community. He was like an adult Boy Scout. I mean, he really was. That's well put. Yeah. Let's talk a little bit about the two sides of George and George's relationship with Shana. You know, there are a great many people around the country who are married to a partner who at first their strength as a character. They're kind of maybe dominating strength as a character. Somebody you're prepared to follow. Seems like exactly what you need. And And you follow that person and you're happy to go along with what they want to do and they will set the agenda in your marriage and in your life. But eventually that the grip tightens and the control tightens and you cease to become an independent person. That's when violence follows.

And it often follows when the woman in the relationship, usually the woman, decides she has had enough of this. is she cannot take it anymore maybe with the help of somebody else in the family some you know something uh creates a situation where she thinks okay i must i've got to leave this relationship or i'll just have no life at all and uh because this person is just simply too controlling and that's a very dangerous situation you know once you started revealing the troubles in their marriage uh the signs were troubling i i think that video clip that showed you know them trying to to take the family picture and him kind of, you know, snapping about like, okay, hold the camera this way or here's how you should do this.

Some people could look at that and say, okay, maybe he's just annoying or, yeah, I wouldn't want to hang out with him, but that's not the sign of violence. But laid against the backdrop of everything else, it's such a disturbing video to see, even in a small thing wanting to have that control. Yes, yes, in the context of the rest of it. And by itself, you know, that's maybe trying to be helpful, but in a way that you can tell, that there's an element of control there that is a little uncomfortable. And of course, while we're on this difficult subject, we want to share some very important

information. If you or somebody that you know is experiencing domestic violence or relationship abuse, a good place to go for advice and for resources is the National Domestic Violence Hotline. That number is 800-799 S-A-F-E. Again, 800-799-7233. Or you can and text the word begin, that's B-E-G-I-N, to the number 8-8-7-88. Finally, you can go to thehotline.org, and there's always someone there who can give you some resources. When we come back, we've got an extra clip from Keith's interview with George TFA's sister. I'm curious, when you spoke with Maria, Keith, did you feel a sense of that struggle that she had?

and on one hand defending everything her brother did really i mean she had a response to everything that you laid out in the story i got the sense that she had gone through a struggle yes but that she didn't she did not uh she didn't hesitate to be absolutely in his corner in in every respect and you know use the explanation that he was using uh that a george's sister simply wouldn't let go of the idea that he couldn't possibly have done this and she knew him as well as anybody could know him that's the you know one of the tragic things about a story like this is that you you recognize that um nobody really knows even those closest to them there there are you know we all have secrets and we keep them buried deep sometimes

uh yeah and someone you have lived with all your life and you think you you know that person well enough that you could never ever possibly get it wrong So you kind of put yourself out there for that person, and then it turns out you are wrong, and it's hard to accept that. So it's especially hard to accept that when you love the person who has committed a terrible act. And what do you do? Stop loving them immediately? No, you can't. You want somehow for this not to be true.

So she was able to take situations without sure. Others would say, okay, yeah, that means, you know, he did this terrible. thing and she could say no there's another explanation there has to be this this isn't him i wonder keith when you go into an interview like that um how do you approach such an interview well you listen i mean it's um it's it's not to us as observers of the story to try to change somebody's mind um i'm i'm very interested in what that person thinks um there are occasions in an interview where somebody is just a perpetrator for example is just being in the system about something which is obviously not true and is trying to pull the wool over your eyes and you have to

call them on it, of course. But a person like George's sister who is going to support him at every turn who you or I might think, you know, that's not, you got George wrong, even though you lived with him your whole life, you don't know him entirely because he did this awful thing. Yeah. I don't want to go there She's allowed to have her point of view And her point of view is a legitimate part of any story We're going to tell Absolutely

You know, to that point We do have some extra sound Of your interview with Maria And this is from when she described Her impressions of George and Shana's relationship And she said that she still had hope Let's listen to a little bit of that

Did you talk to him During the course of this breakup? Yes, he was at my sister's house the summer before Shana died. And it was pretty evident at that point that they were headed towards divorce. And my brother just had a very sad energy about him. He was glad to bring their daughter to the Bay Area so she could, you know, meet with the cousins and have good family time and take a break from Las Vegas. But he was sad. He was, he was at a point where he didn't think it was going to be salvageable. What did he tell you about it and why it wasn't where he?

He just said, he was just so sad. His tone of voice was just sad. But again, in his gentle tone, he was says, yeah, I guess it just isn't going to work out. I think Sean and I are getting a divorce. And he, um, he was just devastated. You could tell. He was, he was just, he was just, devastated. Did he tell you what the specifics of the problem? No, it just isn't happening. It's not working. He must be complained about Shauna in some way or other, even implicitly. No. He actually, his, his characterization of Shauna or his descriptions of anything that interactions he and Shauna had really didn't change at all from when their marriage was doing well. I mean, oh, Shauna's going to do this.

Oh, you know, we're going to go, Shauna and I are going to go to this for their daughter's birthday. Or it was, he never called her names, never said, oh, well, you know, in an aside manner, oh, I can't do this because. John don't wants this or that. You know, none of that kind of thing. It was, in fact, as I'm thinking about it, his characterization of her just never changed from when they were having.

you know a stable relationship to when it was ending that's such a striking account it is and he was very good at not revealing to the rest of the world what was really going on in his life right up until the very end he was already convicted of the crime before we go to the trial I want to talk about Greyhound in all of this. It was so disturbing to me that here is this clearly mentally ill man, clearly had a hard life, was having a hard life, and that this was the person that essentially, you know, evidence showed he used as the scapegoat and the criminal to take out his wife.

I was just so disturbed by the way that Greyhound was used in all of this. I don't know, befriended and then turned into a killer on his behalf. Right. The chances that Greyhound would have been a killer under any other circumstances, I got to think would be practically nil. You know, he was a troubled guy, sure, and he had a lot of issues. But he just wanted to be alone. He just wanted to be out there and then have enough money to be able to buy food.

So he thought these people were helping him by giving him odd jobs to do. I think what to me stood out was that it speaks to the way society, sometimes discards people like a greyhound, someone who's homeless, someone who, you know, has a dependency on drugs, on alcohol. And, you know, the theme was kind of repeated, well, why would you believe him over George, who was this great guy and this fantastic person? And I think it was just such a, such an important lesson of, yeah, you can't base everything on appearances. You can't automatically decide, okay, you're not to be believed, you are to be believed just because of the types of roles you fit in society.

Sure. What I found interesting is that even though Greyhound was said by his own friends to be a known liar, you know, on a scale of one to ten, he was a one and a half. One point five. All the time. Yeah. And, you know, and he was a drug addict and he was an alcoholic and he was a homeless guy and he was, you know, mentally, clearly mentally ill and seriously so.

What I found fascinating, though, is that the jury believed him, and they did not believe George, because Greyhound told the story that made sense, even though he was a known liar, they could believe this from him. I was fascinated that prosecutors took, I mean, what you described accurately as a risk of putting him on the sand, of having him testify. I mean, because that could have gone any number of ways. And, you know, you put it out there that you recognize. You have to let the jury know. I know this person is a known liar. I know this person is mental illness. I know this person is an addict in a number of different ways.

But listen to his story anyway, and you'll recognize that this story is the one that's true. That took a lot of faith. You know, there was something really striking about this. After the verdict, after everything, there was this rather unexpected, I think people would say, kind of confession of sorts from George. Well, George, yes. George at that point was facing life without parole. He had no hope. And he chose that moment to say, okay, well, all right, I did it. But I did it because, you know, I had this mental problem. And it wasn't really my fault. It was the fault of this, you know, difficulty I had. And my brain made me do it. And it was like he was looking for some way, if not to get sympathy. at least perhaps to have somebody say, well, maybe you should have a shorter sentence or maybe we should do a new trial based on your mental illness. And that was enough to make Maria, his sister, decided that maybe she'd had to abandon him because he was clearly not telling the

truth. And, you know, he did not get a hearing on the question. It was rejected for reasons I think anybody could understand. Okay, and after the break, Keith and I are going to answer some of your questions, and they're great questions from social media. Well, we have some questions, Keith, from social media, as we always see for your stories. Let's dive in. These are actually a few questions about some recent episodes of talking Dateline as well. This one goes back to the conversation you and I had last week about your episode in a lonely place. That's the one just to, right? A quick reminder about Chris Smith, yes, a California entrepreneur who went missing back in 2010 and his business partner, Ed Shin, was convicted of his murder.

So here's an audio question from Elizabeth about that episode. Let's listen. Hi, this is Elizabeth. In the case, in the episode of In a lonely place about the disappearance of Chris Smith, has anyone investigated the idea that may be Ed's wife? was also involved, and now he's trying to protect. Just curious, thanks. Well, and the answer to that one is, no, she didn't have any idea, and they did look into it to some degree,

but satisfied themselves pretty quickly that she was one of those people who had been kept in the dark. You know, Ed Shin had become very, very good at hiding his true personality from everybody, and that included his wife. I think it's not something that is that uncommon, unfortunately. It is. It's also so striking to me that marriage is such an act of trust, isn't it? I mean, you've got to trust that your partner's not crazy. They're not a killer, right? On top of other things. But goodness. Okay, so a couple of comments, this is hilarious.

A bunch of you sent in messages with some words of encouragement about something that I actually revealed on a talking date line episode with Josh a few weeks ago about the fact. that I am unable to swim. This was about his episode, Open Water. Here's a comment from Sarah. Let's listen. Hi, this message is for Blaine. Blame, I heard your comment a few weeks ago on talking to the timeline that you don't know how to swim and you're scared of water.

I have taught adults how to swim in the ocean and not teach here. So it's possible that you've got to relax. I mean, you know, you'll lend them to do its job. Sarah, that is so kind. I appreciate it. I, you know, it's funny. I really do have a stronger resolve, though, to learn how to swim. I've got two daughters.

They're very young. And my oldest daughter, she's four, is actually in swimming classes right now. And so I'm starting to take lessons with her instructor on my own. Because, yeah, I just, my whole family can swim or we'll be able to swim, and I don't want to be the odd person out here. That's my motivation here. Very wise. I hope you float. Some of us don't.

Do you? Yeah, like the caller would say to me, just relax, you'll float. I'd just relax. I still sink like a stone to the bottom of the pool. It doesn't work for everyone, just what you're saying. No, it doesn't. I enjoy underwater swimming, but there's no way I'm going to do laps on the surface. Well, we also had some more general, we had some more general questions that people sent in.

This one is at Ak Maui, and Ami. an ambassador who asks, this is to all of you. Is there a case where you believe that they got the wrong person? Oh, yeah. I mean, I think I've done about a dozen of them

where they did get the wrong person. And it can take years and years and years to undo that mistake. The legal system is not set up for, oops, made a mistake, let's change it. It takes a long time. And the resistance to that is extremely difficult to overcome.

But yes, that happens. It takes a long time, and also in those stories, it really takes someone almost acting on their behalf, right? It's not something that people are going back and reviewing, but it takes someone who's kind of dogged in their pursuit of the truth or someone who says, no, you've got to keep looking at this and kind of repeatedly ringing that alarm bell. Some of the most selfless people I've ever met are investigators

and also defense attorneys who do nothing but cases where they believe somebody has been wrongly convicted. So there are people like that in the system where we're trying to make it better. There are. There are. And thankfully so. This is a question, this one is a fun one. It's from, well, her name is fun too, sweet tea with candy. Candy. That's cute. Okay. What is your favorite part of Dateline? Let me ask that of you, Blaine. You're the one who's kind of getting going here. And I, what attracted you to come to daylight?

What did you, what did you like about the idea? You know, if I were to say I love the process of putting our, of reporting these stories. I love doing the interviews. I love the fact that we are able to sit down, take our time, talk to somebody for two, three, sometimes hours. And that there's no rush. I really, really enjoy that. I enjoy that with all the prep in the world, the interviews can just kind of meander off in different directions or that I can get surprised in them or learn things. And then, you know, it's a real

conversation. And so that's just a fun satisfying part. Secondary to that or kind of tangential, I love the connections that come from doing interviews like that. Once you've sat down across from somebody for a good two, three hours and, you know, all of the prep and everything, you kind of have some sort of relationship with them, especially the victim's families. And so, yeah. I enjoy that as well. And then the next part, of course, is getting to talk with you, Keith. Oh, yeah. It's amazing, isn't it?

An incredible gift, I would say, when you're sitting across from someone who has gone through, you know, maybe the worst thing could happen to a person in life. And they've thought about whether or not to participate in a story that we do, and some people don't want to, and that's fine. some people do want to and they want to represent a loved one but have to tell the whole story of what happened and their reactions to it

and they have to have faith in you as well so they have faith in you to tell the story well which is a responsibility you have to take seriously but they're giving of so much of themselves knowing that the whole world is going to see and they do they do it anyway

because something is motivating them to get out there and reveal. It's an extraordinary thing, as you say. Last question. I'm going to ask this one. This is from at Flynn Tucky, who says, are y'all looking forward to coming to Nashville? See you there.

Keith, are you looking forward to it? Can't imagine anything more wonderful than going to Nashville and being in front of a whole crowd of people. I just love being in front of a whole crowd of people for an evening. I'm terrified. Are you kidding? I know it'll be a lot of fun.

I know the world, the people are excited to see you, Keith. That's the biggest thing. The people are so ready to see you, my friend.
