Always a pleasure to have you here, joining us to explore some of the stories that we have been working on recently. And today we're going to look into a story that is chilling. Literally, it was an investigation that was sparked by a house fire.
John Quinones
It's smoky. I can't get in the do.
Deborah Roberts
A 911 call that revealed a possible murder and love triangle that shocked Bismarck, North Dakota. John Quinones and our 2020 team report on this story in our episode the Last Strike. And of course, it's available to stream on Disney and Hulu. So you're gonna wanna see this one. So much to talk about in this case, security camera footage documenting the events leading up to the crime, the intense police interrogation tapes with a Canadian man caught in what turned out to be an apparent affair with the woman who was at the center of the case, and John's exclusive jailhouse interview with one of those convicted in the murder. You're going to get some good details now on how the team approached and also brought this story to air. John Q. Hello, sir.
John Quinones
Hi.
Deborah Roberts
Hey.
John Quinones
Thank you for having me.
Deborah Roberts
Always, always great to see you. You know, you and I are always traveling in different orbits, so I don't get to have you here in person, but hopefully next time.
John Quinones
I miss you.
Deborah Roberts
I miss you. Same here. Same here. And I know you're out, you know, working right now, but take us back to this story in North Dakota. And of course, let's first talk about when we said it's a chilling story. Literally, the winter in North Dakota is no joke in Bismarck, right? I mean, in November and February, the heart of winter.
John Quinones
Yeah. I grew up in South Texas and man, this was bitterly, bitterly cold. Absolutely freezing. It was 20 below when we started shooting and we had to film a lot of it outdoors.
Deborah Roberts
John. We send you to the best places, by the way. You noticed that, right? Yes.
John Quinones
In December. In December, I had rented a car and I remember I was slipping and sliding all over the place in Bismarck, North Dakota, the days are short there. The nights are terribly long. It's dark all the time.
Deborah Roberts
Yeah. Well, I know exactly what that's like. I mean, standing out there in the longest time for the cold. People don't think about that. Part of when we are doing these stories, of us having to collect these stories and go through the elements and when we talk about some of the things that we do in these stories. And I did a story once where I went to a bowling alley and interviewed someone. You actually went to a bowling alley in this particular. And bowled. And did you throw a strike? Did you do well?
John Quinones
Of course. My first roll of the ball was a strike. I'm much better at bowling, by the way, than I thought. Honestly. People were cheering inside the bowling alley and we went there because that's where part of the. The story took place. But it was pretty amazing. I pulled a strike right away.
Deborah Roberts
I'm impressed by that. Cause I never did. Let's talk first. Before we get into the story, though, when you talked about the freezing cold and the temperatures. And this podcast is an opportunity for people to sort of learn a little bit more about what we do. Pull back the curtain, as it were. And you like me, I mean, you pack your bags and you are gone sometimes, like in an instant. I always make sure I've got like sneakers and maybe even a jacket. I mean, Bismarck is a whole different story. But you know, when you're talking about having your to go bag ready and doing things that you might not necessarily be doing normally, what's always key for you to get ready?
John Quinones
Well, I always have an extra bag packed. I have two sets of everything, you know, clothing, shoes, toiletries, and in the winter, a big down filled jacket because you never know. And warm boots. Right. And this time they came very, very handy. In Bismarck, North Dakota, I can imagine.
Deborah Roberts
Your team had a little bit of a snafu. The car broke down at one point and then you got frostbite.
John Quinones
Yeah, I didn't really. You know, my producer, Joe Diaz, who was looking out for me, brought me this nice winter coat with flaps that go down all over the place. And all you could see was my eyes. But truth be told, I look pretty silly hats. And I chose vanity. I chose looking good over warmth and function. My ears were exposed to the cold winter. I was doing an interview outside. They were exposed to the cold wind for just like two or three minutes.
Deborah Roberts
Wow.
John Quinones
Well, after a day, a few days, when I came back actually on Christmas Eve, I noticed the surface of my right ear had turned charcoal color and it was peeling off. It was. Yeah, it was frostbite. It was a gift. My senior producer was not expected.
Deborah Roberts
A valuable lesson to you. Let's wear the hats.
John Quinones
You can imagine how I feel. You know, he was feeling bad. Part of my ear was gone. It grew back.
Deborah Roberts
It grew back. Well, you know, these are the things that we parachute into when we go to these towns in Bismarck. So. And we're going to get to the murder case in just a second. But tell me a little bit about the community because it's always interesting to know something about these communities that we report in. And we don't go to North Dakota a whole lot for our stories. I've been to Florida and South Carolina and Texas and all the typical places, but not North Dakota.
John Quinones
I found it to be a really pretty town. Bismarck. It's right on the Missouri river, the state capital of North Dakota. And compared to other states, North Dakota has a relatively pretty low crime rate.
Deborah Roberts
Yeah. Which is why this case was so surprising. Well, John, it's always great to hear about the behind the scenes, but I want to dig into the reporting here and also how a four legged detective helped solve this case. So don't go anywhere, folks. John and I will be right back.

Deborah Roberts
We are back now with my friend and colleague John Quinones talking about his recent report for 2020 called the Last Strike. Let's talk about this episode, John. It begins as we said, it was a chilling story in a very chilling community. It was in Bismarck, North Dakota and you opened the show with firefighters responding to burning house just outside Bismarck. They find a 42 year old man named Chad Ensel who had been who had died. He was found at the home that he shared with his wife Nikki. And, you know, most folks just saw this as a tragedy in the very beginning, right?
John Quinones
Yeah, yeah. I mean, Chad. Everyone described him as Chad Ensel as an active, very adventurous man who had plans for the future. He had lots of hobbies. He loved bowling. And that's why we're calling this story the last strike. When it came to bowling, he could bowl a perfect 300 score game. He was part of a dart team. And then one day, suddenly, he doesn't show up for work. His wife, Nikki Ansell, calls the police and she tells dispatchers that her house is on fire. She's worried that her husband is inside. And eventually, as you mentioned, Chad's body is found in that burnt out house. And Nikki starts telling people that they had a faulty furnace in the house and that that may have been the cause of the fire.
Deborah Roberts
Yeah. And so everybody sort of thinks that, and they just think that this is just a real tragedy and how sad. And then when investigators hit the scene and they bring a canine dog on the scene, things start to change. The dog notices the smell of something, and this starts an investigation into something. De.
John Quinones
Things looked kind of suspicious inside the house. So they bring in this dog, this canine, Webster, and he's part of the fire department's what they call the accelerant detection unit. And Webster has a keen sense of smell, as so many dogs.
Deborah Roberts
Dogs do. Yeah.
John Quinones
And he can. He can detect all kinds of ignitable liquids, like Sith. 60 different kinds. This dog, Webster, was also able to pinpoint investigators to a certain type of accelerant that it was placed inside the house where Chad and Nikki lived to start the fire. So he was the key to it all. He found the source of that fire.
Deborah Roberts
Yeah. And it doesn't take much oftentimes for police to get that sort of sixth sense that something else is amiss. So they think that this guy died in the fire, and then they discover that he had actually died from gunshot wounds. And then that there was more to this whole accelerant business. There was more in the basement. Evidence of another fire. So suddenly this thing is looking very suspicious, and she, Nikki, is beginning to look a little suspicious.
John Quinones
Yeah. It turns out the fire was started in two different places. In the bedroom and also in the basement. The story pivots from there from a story of sadness now to suspicion, and the focus shifts from accidental fire to. To a homicide investigation.
Deborah Roberts
Yeah, there's. You said this is a small community. There's shock in the community, there's a feeling of betrayal. They start looking at some surveillance, some security footage that they've seen, and they show Nikki walking around town with another guy and clearly having an affair. So once again, the radar goes off for them about her and what potentially could be her involvement.
John Quinones
Yeah, they see him with a Canadian man by the name of Earl Howard. And this was very suspicious to investigators. Not only did security cameras capture the couple all over town, they were also going in and out of Nicky and Chad's house, the house where that fire occurred and where the husband was found dead numerous times. They're going in and out of that house the night of the fire, the night Chad died.
Deborah Roberts
Now, tell us about this couple, because by all accounts, you know, they were a nice enough, happy enough couple. And then, of course, they now discover that she's having an affair, which automatically, for police, will set off some warning bells of something. Talk to us a little bit about the couple and also, too, about Earl. I mean, what connected them and just what police began to unravel when they looked a little deeper.
John Quinones
Well, he was a really nice guy, the husband, and no one ever suspected there was anything wrong, any trouble in that marriage. But not so much for Nikki. Investigators discover surveillance video that show her kissing this man, Howard, the Canadian man, publicly out at Walmart. Of course, you gotta watch those Walmart security cameras. Just the day before Chad goes missing, she's seen kissing this guy Earl. They bring her in for questioning, and they talk to her for about six hours. She tells them that it was Earl Howard, the lover, who shot her husband Chad, while they were struggling over a gun. And she says she was just waiting outside in her car. But investigators, they weren't so convinced of that.
Deborah Roberts
They didn't believe that. And then they bring in Earl Howard, and then he has a story to tell, and they start cutting a deal with him. And then he tells a little bit of a different story there.
John Quinones
Yeah, he denies that he had anything to do with the shooting. Then he claims it was Nikki who shot Chad. Well, Howard was waiting out in the car. He says he offered to take care of things for Nikki. In other words, burn the evidence. And he admits to police that he did have a romantic relationship with Nikki, saying they got together a number of times, including a romantic getaway to the Mall of America in Minnesota. And authorities now know, they now confirm that they were having an affair.
Deborah Roberts
Yeah. Yeah. Once again, one of those things is stranger than fiction. And people always ask us, like, why wouldn't the person just leave?
John Quinones
Yeah.
Deborah Roberts
And Then what about the community, John? Because oftentimes when we go into these communities, you know, you can tell they've been devastated by, you know, something like this. And as you said, it was a fairly low crime rate in that town. And this was something that was shocking. What kind of an impact did it have on the community?
John Quinones
Surprising, because Nikki was seen as just a regular, you know, nice person. She was a good baker. You know, she had a baking business, making bread and cookies and muffins. And while he was working in this area, this man, Earl, was one of her customers.
Deborah Roberts
Howard eventually pleads guilty to a number of charges, including arson, conspiracy to commit arson, and then he eventually is sentenced to 25 years in prison. Nikki goes to trial. She is found guilty, among other things, of conspiracy to commit murder and to commit arson, tampering with evidence, and she's sentenced to life. She's found guilty and sentenced to life with the possibility of parole. John, I want to talk more about that and the outcome in this case. But a few weeks before she was sentenced, you actually talked with Nikki. And after we come back, we'll hear more about what she had to say. So stay with us. You're gonna wanna hear more.

Deborah Roberts
I'm back now with John Quinones on this story that he just reported on the last strike about the death of a Bismarck, North, North Dakota man. The insult Chad Insel murder case. John, this was one. And like all these stories that we cover, you know, I always feel kind of redundant when I say lots of twists and turns, but that's what makes it such a compelling story for us. At the center of report, you interviewed Nikki Insel, the wife of the the murdered man who ultimately was found guilty in his murder. She had been having an affair and she wanted him out of the picture. You spoke with her as she Was awaiting sentencing. And why do you think she was motivated to sit down?
John Quinones
She wanted to continue pleading her innocence. She claims she still wants to get to the real answer. She wants to figure out what exactly happened to her husband, Chad. So she thought you could use this as a vehicle to get to get those questions out.
Deborah Roberts
How hard was it to do this?
John Quinones
Well, I had to go talk to her before we brought the cameras. I made my request for the interview. Nikki talked it over with her older son, who just happens to be a big fan of my show. What would you do?
Deborah Roberts
Of course.
John Quinones
Of course the son convinced his mom that it was a good move, that you were trustworthy. Thank God for that.
Deborah Roberts
What did you make of her, John?
John Quinones
It's pretty clear to me it has been to a lot of people for a long time that she was a bit of a manipulator. She tried to manipulate everyone she could, including us in that interview.
Deborah Roberts
Yeah, we sometimes get gut feelings, I think like anybody else. And sometimes we can tell when we're being manipulated. And then there are times when, know, we walk away thinking, huh, I don't know, maybe. But you felt pretty convinced.
John Quinones
Well, she tells me in the interview that the night of the murder she was actually out again. She keeps changing her story to everyone, to investigators, to the people around her. To me, what she told me was that she had been out for a walk between. At two in the morning. Now, mind you, this is Bismarck in the winter, right? Who goes out there to walk in freezing temperatures? She says she was out there for more than an hour and a half in the interview with me.
Deborah Roberts
That's a little suspect.
John Quinones
And remember, right after, right after the murder, she told police a different story. She said she was inside the house when she heard some gunshots. It was just another one of her many changing stories.
Deborah Roberts
Yeah, she actually acknowledged too, that her story had changed a lot. You're absolutely right. And then she, you know, there's a big question about whether she's being truthful. And she was talking to you about the night of the murder. She talked about being out at 2am which obviously sounds a lot.
John Quinones
And by the way, we did ask her also, what about that kissing scene, the two of you making out at the Walmart the day before your husband's murder. She denied it ever happening. She said it didn't happen.
Deborah Roberts
Even though it's on video?
John Quinones
Yeah, she said he wasn't my type. But later she said when she saw the video, well, a kiss could have happened. She said, quote, have I kissed many friends on the cheek Have I kissed my kids on the cheek? Have I kissed my exes on the cheek?
Deborah Roberts
Yeah.
John Quinones
Yeah, I have.
Deborah Roberts
Oh, my goodness. Yeah. Lots there to unpack, John. Definitely lots there unpack.
John Quinones
And she consistently denies taking part in her husband Chad's murder.
Deborah Roberts
Well, she remains behind bars serving a life sentence in prison. It's a story I'm sure that community will be dealing with and living with for a very long time, and one our viewers certainly won't forget. John, always a pleasure to catch up with you.
John Quinones
Thank you.
Deborah Roberts
Thanks for taking the time. Good to be here and come back to New York. Let's see you sometime in the flesh in the summer. Makes perfect sense. I get it. Well, great. Always great seeing you, John.

Episode Date: December 29, 2025
Episode Title: The After Show: The Last Strike
This episode of the 20/20 After Show dives deep into the chilling true crime story covered in the original 20/20 episode "The Last Strike"—the murder of Chad Entzel in Bismarck, North Dakota. Host Deborah Roberts and reporter John Quinones discuss the peculiarities and behind-the-scenes details of the case: a suspicious house fire, an unexpected love triangle, a key canine investigator, and exclusive interviews with those at the center of the crime. The episode also offers a candid look at the challenges reporters face covering such cases, particularly in unforgiving environments.
[00:33] Deborah introduces the lurid case: a house fire that spawns a complex murder investigation involving a love triangle.
[01:02] The story is set in the bitter North Dakota winter—a literal and figurative chilling case.
"A 911 call that revealed a possible murder and love triangle that shocked Bismarck, North Dakota." — Deborah Roberts [01:02]
[02:19] John shares his experience shooting in brutal -20°F temps, highlighting the physical demands of on-location reporting.
"I grew up in South Texas and man, this was bitterly, bitterly cold... It was 20 below when we started shooting and we had to film a lot of it outdoors." — John Quinones [02:19]
[04:28] John recounts a mishap: car trouble, frostbite, and the perils of prioritizing vanity over warmth.
"Truth be told, I look pretty silly hats. And I chose vanity. I chose looking good over warmth and function. My ears were exposed to the cold...The surface of my right ear had turned charcoal color and it was peeling off. It was...frostbite. It was a gift." — John Quinones [04:34, 05:06]
[05:33] John gives his impression of Bismarck—a small, pretty town with low crime, making the case even more shocking.
[07:30] The show’s recap resumes: firefighters find Chad Entzel dead in his home, initially suspected to be a tragic accident.
"He was found at the home that he shared with his wife Nikki. And, you know, most folks just saw this as a tragedy in the very beginning, right?" — Deborah Roberts [07:30]
[08:06] Chad is described as active, beloved, and an avid bowler—linking the murder’s title, "The Last Strike."
[09:14] The introduction of Webster, a canine trained to detect accelerants, shifts the investigation from accident to arson.
"So they bring in this dog, this canine, Webster...And he can detect all kinds of ignitable liquids, like 60 different kinds. This dog, Webster, was also able to pinpoint investigators to a certain type of accelerant that was placed inside the house..." — John Quinones [09:14]
[10:19] Authorities discover the fire had two points of origin—bedroom and basement—confirming it was set intentionally.
"The fire was started in two different places. In the bedroom and also in the basement. The story pivots from there from a story of sadness now to suspicion." — John Quinones [10:19]
[10:35] Surveillance tips off police to Nikki’s suspicious behavior with Earl Howard, a Canadian man with whom she is having an affair.
"They show Nikki walking around town with another guy and clearly having an affair. So once again, the radar goes off..." — Deborah Roberts [10:35]
[11:46] Nikki and Earl are seen together multiple times on security cameras, including at Walmart the day before Chad’s death.
[12:34] Nikki’s six-hour police interview: she accuses Earl of murder, Earl counters with his version, and each attempts to pin blame on the other.
"She tells them that it was Earl Howard, the lover, who shot her husband Chad, while they were struggling over a gun... But investigators, they weren't so convinced of that." — John Quinones [11:46, 12:34]
[13:15] Earl admits to burning evidence and confirms the affair, pushing the investigation forward.
[16:16] John interviews Nikki before her sentencing. She maintains her innocence and hopes to "get to the real answer" about what happened.
"She wanted to continue pleading her innocence. She claims she still wants to get to the real answer..." — John Quinones [16:16]
[16:34] Nikki agrees to be interviewed after consulting her eldest son, a fan of John’s other show.
[16:58] John characterizes Nikki as manipulative and describes her shifting stories about the night of the murder.
"She tried to manipulate everyone she could, including us in that interview." — John Quinones [16:58]
[17:24] Nikki’s timeline fluctuates—originally saying she was inside, later claiming she was walking outside in freezing temps for an hour and a half at 2am.
"She says she was out there for more than an hour and a half in the interview with me." — John Quinones [17:24]
[18:20] Nikki denies the affair even when confronted with security footage. Eventually, she hedges—"a kiss could have happened."
"She denied it ever happening. She said it didn't happen." — Deborah Roberts [18:31]
"Yeah she said he wasn't my type. But later she said when she saw the video, well, a kiss could have happened..." — John Quinones [18:33]
[18:58] Nikki maintains innocence despite changing stories. Deborah notes the case’s impact on the community and how such stories linger.
"She consistently denies taking part in her husband Chad's murder." — John Quinones [18:58]
[19:04] John and Deborah extend thanks and close out with reminders of where to watch the full episode.
John Quinones on reporting in North Dakota cold:
"In December, I had rented a car and I remember I was slipping and sliding all over the place in Bismarck...the days are short there. The nights are terribly long. It's dark all the time." [02:34]
On the role of the canine detective, Webster:
"This dog, Webster, was also able to pinpoint investigators to a certain type of accelerant that it was placed inside the house where Chad and Nikki lived to start the fire. So he was the key to it all." [09:32]
On Nikki’s shifting alibi:
"To me, what she told me was that she had been out for a walk between. At two in the morning. Now, mind you, this is Bismarck in the winter, right? Who goes out there to walk in freezing temperatures? She says she was out there for more than an hour and a half in the interview with me." [17:24]
On manipulation:
"It's pretty clear to me it has been to a lot of people for a long time that she was a bit of a manipulator. She tried to manipulate everyone she could, including us in that interview." — John Quinones [16:58]
This in-depth After Show provides both the reporting highlights and the human dimension behind "The Last Strike." From the surprising involvement of an accelerant-detecting dog to the unraveling of a supposed perfect marriage, the story starkly exposes the deceptions, small-town shock, and personal hardships of those covering and affected by a tragic murder. John Quinones’ exclusive jailhouse access and Deborah Roberts’ sensitive yet probing approach underscore the complexities of uncovering the truth—even when the facts are buried under a blizzard of lies and frost.
