Host Lester Holt
Tonight on Dave Live.
Matt Tanner
He loved cycling. I was like, man, he could have been riding and got hit. Looking at the body, they were like there was foul play.
Chris Tanner
That's the sad part. We knew we're like, dave, you're in danger.
Prosecutor Andre Mischka
Where David's body was found, it was really difficult to know what had happened.
Interviewer/Reporter
Any obvious sign of trauma? Gunshots, stabbing, anything like that?
Detective Chris Yates
No. Everything seemed very strange.
Detective Greg Lockhart
We spoke to his wife, Katrina.
Narrator/Reporter
I don't know what to do.
Detective Greg Lockhart
She guided us to who could have been suspects.
Katrina Fouts
He came to my door three times threatening David.
Prosecutor Andre Mischka
David had had some sort of relationship with a woman. A possible love triangle out there.
Interviewer/Reporter
A theory starts to emerge of a very unusual murder weapon.
Detective Greg Lockhart
Yes, the toxic mushroom.
Dr. Catherine Aim
It could be fatal.
Interviewer/Reporter
How stunning is it to see something like this?
Dr. Catherine Aim
A real life case. It's very rare.
Prosecutor Andre Mischka
The mushroom angle just threw this into left field.
Interviewer/Reporter
It's like you were watching your friend walk into a trap in slow mot.
Detective Greg Lockhart
It's a game. One big unfortunate game. Just flat out conniving in evil, dangerous
Host Lester Holt
mushrooms and devious lies. Did a sickening mix lead to murder? I'm Lester Holt and this is Dateline. Here's Blaine Alexander with the mushroom mystery.
Narrator/Reporter
This place was her refuge, a respite from a weary world.
Interviewer/Reporter
How often do you walk this road?
Jenny (neighbor who found the body)
Weather permitting, almost daily.
Interviewer/Reporter
This is your normal route?
Jenny (neighbor who found the body)
Yes, it is.
Narrator/Reporter
It was mid April 2020, the early days of the COVID pandemic. The world felt chaotic, but this stretch of road in Noblesville, Indiana offered peace for Jenni Thomas.
Interviewer/Reporter
So typically, what is it like? I mean, lots of cars, lots of traffic.
Jenny (neighbor who found the body)
It's rural. It is a country Road.
Narrator/Reporter
Friday, April 24. A beautiful, picturesque day. Jenny was on her usual walk when she happened upon something horrific.
Interviewer/Reporter
You knew immediately what it was?
Jenny (neighbor who found the body)
Oh, definitely. Definitely did. I knew it was obvious.
Narrator/Reporter
It was a man's body on the side of the road.
Interviewer/Reporter
Like, right in here?
Jenny (neighbor who found the body)
Yes.
Narrator/Reporter
Was this body buried at all or
Interviewer/Reporter
obscured or just kind of right there out in the open?
Jenny (neighbor who found the body)
He was just there laying on his side. Like you would think he was asleep. I stood here for a second thinking, can I help this person? But it was obvious it was too late for me to help him. That's when I knew I needed to go, and I ran.
Narrator/Reporter
Jenny took off up the street toward the nearest house. She found a neighbor who hopped in his truck to go look for himself.
Jenny (neighbor who found the body)
He's the one who called 911.
Narrator/Reporter
911, what's the location of your emergency? There's a dead body laying in the ditch.
Detective Greg Lockhart
They're completely black and blue.
Narrator/Reporter
If the guy is a male, I'd
Detective Greg Lockhart
say, I don't know, older, 30s, 40s, maybe 50s. And it's got a dog collar around his neck.
Narrator/Reporter
Okay, we will have an officer dispatch
Dr. Catherine Aim
there just as soon as possible.
Detective Greg Lockhart
Dispatch calls me and says, we've got a dead body.
Detective Chris Yates
And I was like, is this something, like, real? Do we need to come out there? And he's like, yeah, get in your car and start this way.
Narrator/Reporter
Greg Lockhart and Chris Yates have worked together for more than 20 years at the Hamilton County Sheriff's Office. But this was Yates first death scene as a detective. So Yates followed Lockhart's lead as they looked for clues. What condition is the body in?
Detective Greg Lockhart
He didn't have a shirt on. He had gray sweatpants on. Until we moved him. We didn't notice the shirt that he had, but he had a shirt looked like it was tied around his left wrist.
Interviewer/Reporter
But he wasn't wearing a shirt.
Detective Greg Lockhart
He was not wearing the shirt.
Narrator/Reporter
One theory quickly came to mind. Here in Indiana, the spring season brings
Detective Greg Lockhart
a very specific pastime My mind immediately went to. Since it was April in Indiana, mushrooms are a big thing that people go out and hunt for. So my assumption was maybe it's a mushroom hunter that's collapsed while out hunting.
Interviewer/Reporter
I have to stop you. Mushroom hunting.
Detective Greg Lockhart
Mushroom hunting. So, Morello, mushrooms are edible and people fry them. I don't know how many other different ways you can eat them, but they're very good.
Interviewer/Reporter
It's not mushroom picking. Right. Why is it called mushroom hunting?
Detective Chris Yates
Because they're very hard to find. So you have to know, like, a specific area.
Narrator/Reporter
Detectives wondered if the victim could have been one of those mushroom hunters. But a quick look at the body revealed that was probably not the case. For starters, he wasn't wearing any shoes.
Interviewer/Reporter
You noticed something else that's draped across his body. What was that?
Detective Chris Yates
So it was a rifle sling.
Interviewer/Reporter
For those who may not be as familiar with guns as you are, describe a rifle sling.
Detective Chris Yates
So imagine a big backpack strap, three or four foot long, adjustable. Just would fit on the top of a rifle. And the bottom of the rifle, you can throw it over your shoulder, carry it in the woods. We determine it's an Uncle Mike's brand.
Narrator/Reporter
No shirt, no shoes, and a rifle sling. None of it made sense. But one thing was clear. Officers could tell from the condition that whoever this was had been dead for a few days. As you look at him, is there
Interviewer/Reporter
any obvious sign of trauma? Like, can you look at him and
Narrator/Reporter
immediately tell what happened?
Interviewer/Reporter
Gunshots, stabbing, anything like that?
Detective Chris Yates
No. It was so strange to me. As we started, when the coroners got there and we started to move the body, there was no apparent trauma.
Interviewer/Reporter
At any point, did you think maybe this was a hit and run?
Detective Greg Lockhart
No, because you would generally have signs of trauma.
Narrator/Reporter
With that, another theory popped up.
Detective Chris Yates
We start thinking, man, was it an overdose death? And then somebody didn't know what to do, and so they just dumped his body here.
Narrator/Reporter
Jenny had walked the same route the previous day and didn't notice anything. So investigators thought if the body had been dumped there, it happened the night before. They hoped an autopsy would tell police if they were on the right track. But the results were inconclusive.
Detective Chris Yates
We didn't have a cause of death, and everything seemed very strange and about
Narrator/Reporter
to get even stranger.
Interviewer/Reporter
If somebody eats enough of it and doesn't get any sort of medical help,
Dr. Catherine Aim
then it could be fatal. Yes.
Detective Greg Lockhart
She kind of clutched her chest and then fell back against the wall.
Interviewer/Reporter
You could feel the anger radiating off of him.
Deb Hopkins
Yeah, you could almost feel the heat
Chris Tanner
just looking at her, thinking, what? These are the craziest stories I've ever heard.
Interviewer/Reporter
And they find that none of it's true.
Deputy Prosecutor Adrienne Champine
Nothing's adding up.
Narrator/Reporter
Indiana detectives were trying to identify a man found dead on the side of the road. A victim without a name.
Detective Greg Lockhart
Until once we got him to the morgue, we fingerprinted him, came back, David Michael Fouts.
Interviewer/Reporter
David Michael Fouts. So you got a name?
Detective Greg Lockhart
Got a name. We found out he lived in Pendleton, Indiana.
Interviewer/Reporter
About how far away is that from where he was found?
Detective Greg Lockhart
I think it's 9.5 miles.
Narrator/Reporter
Detectives learned David Foutz was 50 years old. He worked as a senior consultant at the massive technology company Salesforce.
Matt Tanner
He was always trying to help other people in the sport.
Narrator/Reporter
Matt Tanner met David Fouts years earlier at a cycling event.
Matt Tanner
It was always exciting going to the finish with Dave because he was all grinning ear to ear because we were the fastest guys, and he loved it.
Interviewer/Reporter
So initially, it was literally your shared speed that brought you two together.
Matt Tanner
Yeah, for sure.
Narrator/Reporter
When Matt started his own cycling group, Dave was one of the first to join.
Interviewer/Reporter
What kind of community, what kind of feel were you trying to build here?
Matt Tanner
So, honestly, like, initially, we were very race focused. It was called roll fast and we wanted fast cyclists.
Interviewer/Reporter
You wanted to win.
Matt Tanner
Yeah. And then we felt like there was more we could do with the club. We kind of decided, let's focus on what we call mental fitness.
Interviewer/Reporter
Did Dave fit into that?
Matt Tanner
Yeah, very much.
Narrator/Reporter
Matt's wife, Chris, was the group's driver and cook.
Chris Tanner
That's really how I got to know Dave is because Dave was always, like, behind the scenes helping and working. Like, he'd come in the kitchen with me while I'm cooking for the team, and he'd be like, can I help? And he. Sure. I'd put him to work. And so he was the mechanic for when they would go on their camps. And so sometimes Dave would stay behind and not even ride while I'm cooking and preparing lunch or dinner. You know, he's in there repairing a bike that fell apart the day before. So he was always in the position of helping people.
Narrator/Reporter
In fact, his friends say Dave was truly a Renaissance man.
Chris Tanner
He had so many other just interests. And, you know, he would bring us eggs from his farm because, you know, he's like, oh, my chickens are laying crazy eggs. You want some of them? And we're like, yeah, we'd love that. And he never had children of. And so he created a life that was very fulfilling, and I thought that was super cool.
Interviewer/Reporter
That's notable.
Katrina Fouts
Yeah.
Narrator/Reporter
In the blur of all that activity and movement, the friends say David often kept his personal life personal. He divorced his College Sweetheart in 2018.
Interviewer/Reporter
Did you know much about their divorce, about their split?
Matt Tanner
It happened quickly and I would say quietly.
Narrator/Reporter
By 2019, he was married again to a woman named Katrina. She'd grown up in a town about an hour away where her father owned a roofing business. She'd been married once before and had several grown children. Katrina and David first met through cycling.
Chris Tanner
He was so passionate with her, and we had never seen that side of him before.
Matt Tanner
And he wanted to be a provider for Grandkids and kids that he didn't have.
Chris Tanner
He loved her kids. He loved her kids.
Interviewer/Reporter
When did you first find out that something had happened to Dave?
Matt Tanner
I believe we saw it on the news. I also thought where they found him was like a road that was plausible. You could be riding on and get hit. It was a road that I've ridden on a lot.
Dr. Catherine Aim
Yeah.
Matt Tanner
Wasn't that far from his house that I was like, man, he could have been riding and got hit.
Narrator/Reporter
But police already knew. This was no biking accident.
Katrina Fouts
Sheriff's office.
Narrator/Reporter
It was late that night when they left the scene to break the news to David's wife.
Detective Greg Lockhart
Hi, Katrina. My name is Craig Lockhart. I'm a Texan here in King County.
Narrator/Reporter
They first needed to make sure they had the right house.
Detective Greg Lockhart
Do you have a recent picture of David?
Katrina Fouts
Let me go get my cell phone.
Chris Tanner
Okay.
Narrator/Reporter
Katrina went inside to retrieve her phone. When she returned, detectives looked at the photo and gave her the news.
Detective Greg Lockhart
We have reasonably at this point that he is dead. We found him today.
Interviewer/Reporter
How did she respond?
Detective Greg Lockhart
She kind of clutched her chest and then fell back against the wall. Stay up here with me for a second. And we need to talk about everything and try to figure out what's happened in the last couple days.
Narrator/Reporter
Katrina thought she knew.
Katrina Fouts
He's threatened suicide multiple times, and I've
Deb Hopkins
called the police a few times.
Interviewer/Reporter
There's.
Katrina Fouts
There was nothing they could do unless
Deb Hopkins
they said he
Katrina Fouts
admitted it.
Detective Greg Lockhart
We just need to figure out things with him and figure out the story.
Katrina Fouts
I, I, I don't. I, I'm. I don't. I. I don't know what to think. I don't know what to feel right now, because this situation is. I love my husband no matter what he's done.
Narrator/Reporter
She invited them inside.
Katrina Fouts
I don't know what to do.
Detective Greg Lockhart
I mean, we'll. We'll try to help you walk through some stuff.
Katrina Fouts
It's not my fault. I didn't do enough.
Detective Greg Lockhart
Can I turn on the light?
Katrina Fouts
Yeah.
Detective Greg Lockhart
There we go.
Katrina Fouts
Do you mind if I have a. I got to have a cigarette.
Narrator/Reporter
She explained that she and David had been going through a rough patch. He was staying at another apartment, and she hadn't spoken to him for days.
Katrina Fouts
Yeah, I physically spoke to him on Tuesday.
Detective Greg Lockhart
On the phone or in person?
Katrina Fouts
In person.
Narrator/Reporter
She said she'd worried about his mental state that last time she saw him and that he'd been talking about suicide.
Katrina Fouts
He just didn't want to be in here anymore. My skin's crawling. I feel like I got bugs coming out of my skin.
Interviewer/Reporter
Was there anything to indicate to you that he possibly died by suicide?
Detective Greg Lockhart
No, nothing at all.
Narrator/Reporter
The detectives knew her theory couldn't be right. David wasn't wearing any shoes, and yet
Detective Chris Yates
bottom of his feet are clean, so he didn't walk there and collapse anything like that. So that means that he didn't die in that location.
Interviewer/Reporter
Whatever happened didn't happen here.
Detective Chris Yates
Correct.
Detective Greg Lockhart
He did not miracle himself into that ditch. So there's no way detectives needed to know.
Narrator/Reporter
Did David have any enemies? His wife certainly thought so.
Katrina Fouts
He came to my door three times, threatening David.

Narrator/Reporter
24 hours into their investigation, all Hamilton County Sheriff's detectives had was a growing list of what didn't happen to David Fouts. They knew it wasn't a biking accident. Didn't look like suicide either. So they took a closer look at David's personal life. And sure enough, Katrina told detectives her husband had been having an affair.
Katrina Fouts
He wasn't the type of person I would expect to be involved with a woman like this.
Detective Greg Lockhart
David had had an affair with their housekeeper, and David had bought her a new car. David had allowed her to use his address in Pendleton so her kids could go to Pendleton schools.
Interviewer/Reporter
Oh, wow.
Detective Greg Lockhart
And that David was sending all this money to this girl he owned up to everything.
Katrina Fouts
I wasn't mad, but I did a forensic accounting, you know, and I'm like. And you spent eight grand on a car and spent over $30,000. I'm sorry. I know. I'm sorry. I'll stop. I'll stop. I'll stop.
Narrator/Reporter
But Katrina said he didn't. The infidelity continued, and then a man showed up at their doorstep with a threat.
Detective Greg Lockhart
Do you know who this guy was?
Katrina Fouts
I've never seen him in my life.
Detective Greg Lockhart
Okay. Did he say who he was?
Katrina Fouts
No, and I didn't ask.
Interviewer/Reporter
Was this one of the woman's partner? A spouse, a husband?
Detective Greg Lockhart
Katrina alluded that it was a father of one of her children.
Interviewer/Reporter
Who was she saying? Upset with David?
Detective Greg Lockhart
Yes.
Interviewer/Reporter
Because of this affair?
Detective Greg Lockhart
Yes. She described him very well dressed, wanted to speak to David. David was never there. But this unknown gentleman went out of his way to tell Katrina, you're in no danger. I'm not gonna harm you. My issue is with David.
Narrator/Reporter
Katrina said she wanted to call the police to report the man, but David stopped her.
Matt Tanner
He wouldn't let me call the police
Katrina Fouts
about the man that came to the door to threaten to kill him three or four times.
Narrator/Reporter
The housekeeper told Dateline she and David were not having an affair. And when police interviewed her, she said he was just helping her out.
Detective Greg Lockhart
He did not buy her a car, according to her. And he really hadn't given her that much money.
Interviewer/Reporter
Okay.
Detective Greg Lockhart
But he had allowed her to use his address for her kids.
Interviewer/Reporter
Does she give you names of her children's fathers?
Detective Greg Lockhart
Yes.
Narrator/Reporter
The housekeeper didn't think anyone she knew had threatened David, but she gave them three names. Detectives tracked them down.
Detective Greg Lockhart
All three males were accounted for. Two of them were in prison, and one lived in Florida. Okay, so. And the one in Florida had had an alibi.
Narrator/Reporter
So that road turned out to be a dead end. And detectives were back at square one on finding David's killer and finding out what killed him.
Detective Chris Yates
The forensic pathologist said, look, I know there's not a glaring cause of death, but it is not natural. He did not have a heart attack. He did not have a stroke. This is some kind of other death.
Narrator/Reporter
However, detectives did have, well, maybe not quite a lead. But during the autopsy, the pathologist discovered something in David's stomach.
Interviewer/Reporter
What do you guys find?
Detective Greg Lockhart
The only thing that was really there looked like little chunks of mushroom. Mushroom mushrooms.
Narrator/Reporter
Those mushrooms led them to Purdue University. University and the lab of Dr. Catherine Aim, a professor of mycology.
Interviewer/Reporter
Help me understand what a professor of mycology is. What do you study?
Dr. Catherine Aim
We study fungi. All aspects of fungi, actually.
Interviewer/Reporter
In my lab, you get a phone call, essentially asking to help Police solve a murder.
Dr. Catherine Aim
Yes. Yes. I was happy to see if I could help identify the mushrooms.
Interviewer/Reporter
That had to have been a surprising phone call to say the least.
Dr. Catherine Aim
It's a little outside of my normal realm of day to day activity. Yeah.
Narrator/Reporter
So Dr. Raim got to work using DNA sequencing to identify the mystery mushrooms.
Interviewer/Reporter
What kind of mushroom was this?
Dr. Catherine Aim
It was something called Leukocybe conatum.
Interviewer/Reporter
And what happens if you eat that kind of mushroom?
Dr. Catherine Aim
Well, this is where science is a little uncertain. There are reports of people eating this mushroom without problem. There are other reports of people having toxicity from eating this mushroom that it has a toxin called muscarine in it. It makes people sweat and salivate and cry and basically excrete most of their
Narrator/Reporter
liquid very, very quickly, leaving someone dehydrated and weak.
Interviewer/Reporter
Do we typically see cases of people dying from muscarine poisoning? No, we do not.
Narrator/Reporter
So toxic, but not necessarily deadly. No real answers there. Maybe another conversation with David's wife could shed light on what happened. Or maybe not.
Chris Tanner
She said that she surfed with her husband and her husband died in her arms. And while she was surfing, she had her arm was bitten off by a shark.
Detective Greg Lockhart
It's fanciful, just weird stories.
Narrator/Reporter
When police first spoke with David's wife, Katrina, she was overwhelmed with emotion.
Katrina Fouts
I don't know what to think. I don't know what to feel right now.
Narrator/Reporter
A few days later, they wanted to talk to her again. So she came down to the station.
Detective Greg Lockhart
Glass of water or some coffee or anything.
Narrator/Reporter
Black coffee. Detectives noticed a few things right off the bat. Katrina liked to talk a lot.
Katrina Fouts
Then it tells you how much you
Narrator/Reporter
got left, often adding details they didn't ask about.
Katrina Fouts
And then we relocated to Lamira, Brazil,
Narrator/Reporter
state of Sao Paulo.
Katrina Fouts
I had uterus cancer. Greyhounds, they have their own way of doing things.
Detective Greg Lockhart
It was hard to get her to answer direct questions. She would break off into a tangent and still never really answer your question.
Narrator/Reporter
Katrina told them stories of a rather high profile profession as a fashion designer with big ticket clients.
Katrina Fouts
We made all little NASA's touring clothes. Last year we got Kardashians wearing our fricking clothes right now. Did you watch this video?
Detective Greg Lockhart
I think they're a pretty big deal, aren't they?
Narrator/Reporter
To the detectives ears, the stories sounded far fetched. It's a pattern David's friends had noticed from the jump. Not long after they met Chris and another roll fast wife took Katrina to lunch. David had introduced her by a nickname, Edie.
Chris Tanner
In that lunch, Edie explained and talked about her life and had the craziest stories I've ever heard. Like in my 57 years, I've never had a luncheon like that.
Jenny (neighbor who found the body)
Wow.
Chris Tanner
She knew about me and my first husband who had passed away. And I don't know if that was a catalyst for her to say crazy things, but she said that her first husband died in her arms and that she was from Brazil, that's where she lived, and she surfed with her husband and her husband died in her arms. And while she was surfing, she had her arm was bitten off by a shark. Now we're both looking at her. She has two arms. So I don't know what the follow up question for that is. So these are the craziest stories I've ever heard.
Narrator/Reporter
So did Katrina just like to spin tall tales for fun, or were her lies dangerous? Detectives started digging into her past and were shocked by what they found.
Deputy Prosecutor Adrienne Champine
I was assigned to Superior Court one
Narrator/Reporter
At that time, Adrienne Champine was a deputy prosecutor with Hendricks County, Indiana. She first crossed paths with Katrina in 2011. After Katrina reported that she'd been raped by a friend of her then boyfriend's,
Deputy Prosecutor Adrienne Champine
she gave him a ride back to his house. She went inside with him. She was going to use the bathroom, and that at that time, he grabbed her and assaulted her.
Narrator/Reporter
She said that the attack was so brutal it hurt to sit for too
Deputy Prosecutor Adrienne Champine
long because of these traumatic injuries that she had sustained from the attack.
Interviewer/Reporter
Did she go to the hospital or the er?
Deputy Prosecutor Adrienne Champine
She did go to the hospital.
Interviewer/Reporter
She was checked out.
Deputy Prosecutor Adrienne Champine
She was. The police followed up, of course, with the medical providers. They told the police, no, she did not have traumatic injuries.
Narrator/Reporter
She said she almost didn't report the assault because of what she did for a living.
Deputy Prosecutor Adrienne Champine
She told them that she was a photographer for celebrities and famous magazines and that it would damage her reputation to be in this situation.
Narrator/Reporter
And she told more stories about herself that to investigators just seemed off.
Deputy Prosecutor Adrienne Champine
She said that she owned houses, I believe she said several houses in Indiana that she also had property or house in Florida. They could not find any evidence that she owned any of these properties. They also did not find any evidence that she had any source of income for the previous three years. So.
Interviewer/Reporter
So police look into all of this, right. And they find that none of it's true.
Deputy Prosecutor Adrienne Champine
Nothing's adding up.
Narrator/Reporter
Most crucially, the details of the assault weren't adding up. The accused man denied raping Katrina and told police he had a witness, another woman, who was part of the entire encounter.
Interviewer/Reporter
So they talked to her?
Deputy Prosecutor Adrienne Champine
Yes.
Interviewer/Reporter
What does she say?
Deputy Prosecutor Adrienne Champine
They Bring her in. And she corroborates everything that the male said. It was consensual the entire time.
Interviewer/Reporter
So when police go back to Katrina, what does she say? What's her explanation?
Deputy Prosecutor Adrienne Champine
Her response was, I think I need an attorney.
Narrator/Reporter
Police charged Katrina with false informing and dropped the investigation into the man.
Deputy Prosecutor Adrienne Champine
The level of crime he was looking at at that time, it would have been a B, felony rape, which would have carried a 20 years in prison. This is a very serious allegation.
Interviewer/Reporter
This is more than just a little white lie.
Deputy Prosecutor Adrienne Champine
Correct.
Interviewer/Reporter
As a prosecutor, you know that women coming forward in sexual assault cases can be extremely difficult Anyway, there's the question of believability. How upsetting is it to see something like that?
Deputy Prosecutor Adrienne Champine
It is upsetting, and I think what's very upsetting about it is that you want to believe the victim when they come forward. And I think she was banking on that when she came forward with this lie.
Narrator/Reporter
Katrina was sentenced to almost a year of probation and ordered to pay about $6,000 in restitution. As they dug further into her background, detectives investigating David's murder tracked down Katrina's family and existence. Boyfriend and even her ex husband. They admitted she could be charming and was always down for a good time.
Detective Greg Lockhart
Anything you want to say?
Katrina Fouts
I'm really excited. And all I can say, people, is you have to be there.
Narrator/Reporter
The investigators learned that aside from sometimes helping at her father's roofing company, there was no evidence that Katrina had worked a day in her life. In fact, she seemed to lily pad from one relationship to the next.
Interviewer/Reporter
How was she getting by?
Detective Greg Lockhart
Wherever the money was is where she stayed. She was all about money.
Interviewer/Reporter
As you're talking to more and more people, this pattern is starting to develop about Katrina. One, financially, but two, making allegations against her romantic partners.
Detective Greg Lockhart
Correct.
Narrator/Reporter
She reported her first husband to police, saying he hit her. She pressed charges. He denied hitting her, but pleaded guilty to disorderly conduct. Once married to David, Katrina accused him of shoving her. David pleaded guilty to a misdemeanor domestic battery charge. Detective Lockhart looked at all of this. He dug into David's past and couldn't find any history of David being physically abusive.
Interviewer/Reporter
As you're looking at this, did you believe that he pled guilty because he, in fact, was guilty of this or because it was the path of least resistance?
Detective Greg Lockhart
I think it was the path of least resistance. Sometimes in the legal system, it's easier just to bite the bullet and move on past it, so to speak.
Narrator/Reporter
Months later, Katrina told police he pushed her again, but this time, David Said Katrina was lying. David's attorney told Detective Lockhart phone records show David was nowhere near Katrina when the alleged assault took place.
Detective Greg Lockhart
According to his attorney, he was going to fight that case, but he passed before the case came up to hear abusive.
Jenny (neighbor who found the body)
No, no.
Interviewer/Reporter
Does that sound.
Matt Tanner
I've never seen Dave violent with anybody.
Narrator/Advertiser
Anyone.
Narrator/Reporter
David's friends, the Tanners, believe Katrina was lying when she told police he was suicidal. They never saw that, but they did see a dark side to the marriage. They remember talking to David for hours one night about his relationship.
Matt Tanner
It was kind of the same thing over and over. But at some point, he said, if I end up dead, she. She killed me.
Chris Tanner
He said this words, right?
Matt Tanner
And. And we looked at each other and we're like, Dave, you have to.
Interviewer/Reporter
You have to leave.
Matt Tanner
Get rid of her.
Narrator/Reporter
And then in the same breath, he's
Interviewer/Reporter
saying he wants to go back to her.
Matt Tanner
And he said, I can't. He said, I can't leave her.
Jenny (neighbor who found the body)
Can't leave her.
Chris Tanner
He loves her.
Narrator/Reporter
Matt and Chris looked back on that conversation and became convinced Katrina killed their friend, and they shared that with detectives. Detective Lockhart would now put Katrina's words under a microscope, starting with where she was when David went missing.
Katrina Fouts
I meet Terry over at the country house.
Narrator/Reporter
Terry, who was that?

Narrator/Reporter
Detectives had more questions for David Founts wife, Katrina, starting with a key one. Where was she the night David was murdered? She told detectives she'd been with a man named Terry Hopkins, a longtime family friend.
Detective Greg Lockhart
Pops or Hoppy.
Interviewer/Reporter
Okay.
Detective Greg Lockhart
Father from another mother. These are all things that she told me about Terry. Nicknames, nicknames between the two.
Interviewer/Reporter
Clearly, the two of them are close.
Detective Greg Lockhart
Very close.
Katrina Fouts
Him and my dad are lifelong Masons.
Detective Greg Lockhart
Okay.
Katrina Fouts
And best friends.
Narrator/Reporter
Katrina said she'd met up with Terry at a house she rented in the country.
Katrina Fouts
I meet Terry over at the country house because we were gonna grab some food because he said he was in the mood for Chinese. We were gonna spend some time together, watch a movie.
Detective Greg Lockhart
And you said this was six to seven at night?
Chris Tanner
Yeah.
Detective Greg Lockhart
Somewhere in there?
Jenny (neighbor who found the body)
Yeah.
Katrina Fouts
It wasn't even dark yet.
Narrator/Reporter
Katrina said she stayed there through the night. The next day, she went back to the home in Pendleton she shared with David. Police needed to speak with Terry, but he refused. So they detained him and tried to get him to answer some questions.
Detective Greg Lockhart
Are you willing to give us a statement and talk to us about this?
Narrator/Advertiser
My good sense tells me that I need to wait and request for an attorney.
Detective Greg Lockhart
If you change your mind, you want to talk to us, you have her number.
Detective Chris Yates
Okay.
Narrator/Reporter
Police had to let Terry go, but they kept digging.
Interviewer/Reporter
So he doesn't talk to you?
Detective Greg Lockhart
He doesn't answer any questions other than to tell me. He called me one time and told me what a pathetic job I was doing with my investigation and that he was going to sue me.
Narrator/Reporter
Terry wasn't spooked by law enforcement. He'd spent 33 years with a police department in a nearby county where he'd worked his way up to captain.
Interviewer/Reporter
How was he as an officer?
Deb Hopkins
Oh, he was good. He had a good sense of humor, but also a compassion for people, especially the underdogs.
Narrator/Reporter
This is Deb Hopkins, Terry's ex wife. Terry wasn't talking to police, but Deb certainly was.
Deb Hopkins
He asked Me numerous questions about Terry and Katrina.
Narrator/Reporter
Deb told investigators she'd been Terry's wife for 45 years, and their life together was mostly good.
Deb Hopkins
I could start a sentence, he could finish it, and it was just so easy, so relaxed, so comfortable.
Narrator/Reporter
But Deb says their happy marriage unraveled after Terry retired.
Deb Hopkins
He would get very upset very quickly, and he would cry, and he never cried, you know, over the slightest thing. We had a neighborhood cat that died, and he just bawled.
Narrator/Reporter
It was a sudden change, so concerning. They went to see a neurologist, and
Deb Hopkins
that's when we found out that he had had a frontal lobe stroke. A stroke? Yeah. He didn't even know it. I thought strokes made your face sag or your arm, you lose. A frontal lobe. Stroke does none of that. It affects your mind, it affects your judgment. It affects your ethics. It affects your reasoning, your empathy.
Narrator/Reporter
Deb says Terry was never the same after his diagnosis. He became verbally abusive and started having an affair.
Deb Hopkins
I said, I'm leaving. Hardest thing I ever did up to that point.
Narrator/Reporter
After the divorce, Terry moved in with his friend Katrina's father, and he started spending a lot of time around Katrina. He was still in touch with Deb, too. She noticed that whenever Katrina's husband, David, came up in conversation, Terry would fly into a frenzy.
Deb Hopkins
He would talk about David with such venom.
Interviewer/Reporter
You could feel the anger radiating off of him toward David.
Deb Hopkins
You could almost feel the heat.
Narrator/Reporter
So Katrina's alibi for the night her husband was killed was a man who openly hated David. That was suspicious. And so was this. On the night police tried to question Terry four days after the body was
Detective Greg Lockhart
found, he had a band aid on each hand and one big one on his forearm. And the initial thing that drew my attention is where his glasses sat. There was some blood that was a wound. And I thought, you know, these look like he could have been in a fight.
Narrator/Reporter
Detective Lockhart requested a search warrant to collect Terry's DNA and take pictures of his body.
Detective Greg Lockhart
So he had a cross up here, and it looked like a tattoo or a necklace. Necklace, Necklace. There was a bruise that looked just like that cross, like he had held something against his chest really tightly, but his whole chest was bruised.
Narrator/Reporter
Katrina told police she was not only with Terry the night David likely died, but she also admitted to being with Terry two nights later on a Thursday,
Detective Chris Yates
which is also the night we believe that the body was dumped.
Narrator/Reporter
When police dug through Terri and Katrina's phone records, they learned the two were in constant contact, except for that night.
Detective Chris Yates
Their cell phones got Shut off on the night that we believe the body was dumb for a period of like four hours when they had this long communication string, talking all the time, and all of a sudden, both phones shut off.
Narrator/Reporter
But Detective Yates discovered that didn't necessarily mean the two weren't in communication. When he searched their cars, he found a walkie talkie in each.
Detective Chris Yates
Like a small walkie talkie, like you could, you know, use as a kid or you might see, you know, at some big box store that they talk on.
Narrator/Reporter
And Detective Yates noticed other things in Terry's car.
Detective Chris Yates
A lot of different types of knives, tools, zip ties, tarps.
Interviewer/Reporter
It's like a perfect murder cover up kit.
Narrator/Reporter
Yes, investigators now believed Katrina and Terry worked together to kill David.
Narrator/Advertiser
But why?
Interviewer/Reporter
What did Katrina stand to gain from David's death?
Detective Greg Lockhart
Everything. A half million dollar life insurance policy. The $40,000 from Salesforce as like, a severance pay. The house, the two motorcycles, the three cars. Well, more cars than that. His specialized bicycles that were, I mean, tens of thousands of dollars expensive. Literally everything.
Interviewer/Reporter
She would have had a very lucrative payday from David's death.
Narrator/Reporter
Yes, but Detective Lockhart knew means and motive were not enough to make an arrest. To make a murder case, they needed to nail down a code. Cause of death. Maybe the clue they needed was this.
Detective Greg Lockhart
There was a screenshot of a death cap mushroom.
Narrator/Reporter
You can learn a lot about a person by looking through their phone. And when detectives reviewed the contents of Katrina's photo roll, they stumbled upon one very telling picture.
Detective Greg Lockhart
There was a screenshot of a death cap mushroom.
Narrator/Reporter
After speaking with mushroom expert Dr. Aim, they learned the death cap mushroom is, as its name implies, deadly. The elkanata mushrooms found in David's stomach are considered a less toxic variety. But it turns out the two look a lot alike.
Dr. Catherine Aim
They're both tall, stately, pure white mushrooms. Big white cap, white gills. So very, very similar.
Interviewer/Reporter
Is it possible that if someone were going out trying to gather mushrooms, that they made a mistake? One mushroom for the other, Try and grab the deadly one, but get the other instead?
Dr. Catherine Aim
Yeah, I think that's a very reasonable hypothesis.
Narrator/Reporter
So maybe the detective's first inclination was at least partially correct. Maybe the crime did involve mushroom hunting after all. But it was Katrina and Terry who'd been on the prowl, planning to kill David with the lethal death cap mushroom, but accidentally grabbing the less toxic one instead. Detective Lockhart explored this theory, while Katrina seemed to explore a friendship with him.
Katrina Fouts
Hey there.
Narrator/Reporter
Good afternoon.
Katrina Fouts
So, how are you?
Detective Greg Lockhart
A ball of stress. Katrina.
Interviewer/Reporter
How often is she reaching out to you guys.
Detective Greg Lockhart
Oh, my goodness. Daily, Hourly.
Narrator/Reporter
Are your parents still living? I'm assuming they are.
Interviewer/Reporter
To say what?
Detective Greg Lockhart
Talk about life, living, pursuit of happiness.
Katrina Fouts
I just want you to know, Greg,
Narrator/Reporter
I appreciate you, but at the same
Interviewer/Reporter
time, you are getting, I mean, growing mountains of evidence that make you fairly certain that she's the person who killed her husband.
Detective Greg Lockhart
Yes.
Interviewer/Reporter
How do you square those two?
Detective Greg Lockhart
Well, it's a game. This is one big, unfortunate game that we have to. To play. I have to be nice to her and not let her know what I know and keep her talking to me.
Narrator/Reporter
Detective Lockhart wasn't sharing with Katrina that mountain of evidence he'd been collecting against her and Terry. The DNA results came back five months
Detective Chris Yates
after the murder, and Terry's DNA was on the shirt that was still on the body of David.
Interviewer/Reporter
This is a horrible piece of evidence for Terry.
Detective Greg Lockhart
Very damning.
Narrator/Reporter
The report also showed David's DNA was found in the back of Terry's car. After reviewing the evidence, Hamilton county prosecutor Andre Mischka developed a theory.
Prosecutor Andre Mischka
So, in our theory, the mushrooms were an attempt to kill him, but because they were Elkanatum and not Amanita verosa, they did not.
Interviewer/Reporter
Weakened him in some form.
Deb Hopkins
Right?
Prosecutor Andre Mischka
Weakened him in some form. Now, he was dehydrated, but then they had to pivot and. And go a different tact. And so we believe that in the early morning hours, that that's when the asphyxiation occurs.
Narrator/Reporter
Part of that theory that David likely died by strangulation. That would also explain those injuries detectives saw on Terry's hands and chest. Prosecutor Mischka thought that after strangling David, Katrina and Terry drove out to the country to dump his body. And as for that rifle sling found around David's neck, they thought that was to help roll him into the ditch.
Prosecutor Andre Mischka
We believe is a means of helping to give something to grab onto in that part of his body.
Narrator/Reporter
The prosecutor thought this would be the best the case was going to get. It was now or never.
Interviewer/Reporter
You arrest Terry, Tell me how that happens.
Detective Greg Lockhart
So we had the Indiana State Police SWAT team descend upon him. They were trying to call him out, and it took 10 to 15 minutes.
Narrator/Reporter
Police found Katrina driving her car, and
Detective Greg Lockhart
then our SWAT team took her down.
Narrator/Reporter
When they searched her car, they found $40,000 in cash and a burner phone.
Detective Greg Lockhart
On her cell phone, she had searched how to disappear and never be found, how to get fake IDs.
Interviewer/Reporter
She searched that specifically?
Detective Greg Lockhart
Yes.
Narrator/Reporter
In September of 2020, Katrina and Terry were charged with murder and conspiracy to commit murder with two Defendants awaiting trial in jail. Investigation investigators couldn't help but wonder if one of them might flip.
Detective Greg Lockhart
Terry was interviewed in an attempt to do a plea agreement.
Narrator/Reporter
He was in bad shape, battling heart and memory problems, but he told them a story.
Detective Greg Lockhart
He said that Katrina had used mushrooms to poison him and cook them, put them on a pizza or something. David was very lethargic from eating the mushrooms. Terry presented himself. There was a. And Terry said, I put my arm around him as he was fussing and just squeezed for a few minutes.
Interviewer/Reporter
And then strangled him. And killed him.
Detective Greg Lockhart
Yes.
Narrator/Reporter
Terry died a few months after talking to investigators. Then, In February of 2022, Katrina went on trial. Detective Lockhart says Terry's statement wasn't presented to the jury as evidence because Terry had been sick and mentally diminished when he talked. And the judge threw out that screenshot of the death cat mushroom found on Katrina's phone because those weren't the kind of mushrooms found in David's stomach.
Prosecutor Andre Mischka
That piece, he thought, was just too far of a reach to be relevant to present to the jury.
Narrator/Reporter
The defense argued the state's story was just that, a fiction with a gaping hole at the center of it. If prosecutors couldn't say exactly how David was killed, how could they tell the jury who killed him? After a week of trial, which was recorded on audio, the jury reached a verdict.
Detective Greg Lockhart
We the jury, find the defendant, Katrina Louise Fouts, not guilty of murder.
Prosecutor Andre Mischka
There's the sudden seeking feeling of, oh, gosh, this might go sideways.
Narrator/Reporter
But on the conspiracy charge, we, the
Detective Greg Lockhart
jury find the defendant, Katrina Louise Fouts, guilty of conspiracy to commit murder.
Narrator/Reporter
Katrina was sentenced to 34 years in prison. She'll be in her 80s by the time she's released.
Matt Tanner
I was happy she went to jail and all, you know, the system worked, I guess. Doesn't bring Dave back.
Narrator/Reporter
Terry's ex wife, Deb, believes Terry's stroke left him open to manipulation by Katrina.
Deb Hopkins
I think she made herself out to be a victim of David's, and that's why he started hating him. She manipulates people, and she knew how to manipulate him.
Interviewer/Reporter
You think Terry fell victim to it?
Deb Hopkins
Oh, I know he did.
Interviewer/Reporter
Do you think that if Terry had never had this stroke, he would have ever been a part of this?
Deb Hopkins
No, he would not.
Interviewer/Reporter
No question.
Deb Hopkins
No question.
Narrator/Reporter
Deb says she's found a way to forgive Terry, but she doesn't condone what he did. And David's family is always on her mind.
Deb Hopkins
I've always regretted not reaching out to David's family in offering my condolences in
Interviewer/Reporter
case they are watching. What would you want to say to them?
Deb Hopkins
I'm so sorry. I know I'm not responsible for it, but David, you know, he had a full life ahead of him and I'm so sorry that it ended that way. She could have divorced him and could have gone on, but she didn't. And he died in such agony. And that breaks my heart.
Narrator/Reporter
In the years after David Foutz's death, Matt Tanner organized a mobile memorial ride for his friend, the name Dave Fast.
Matt Tanner
Yeah, it was a spin off of Rollfast and Dave. We should have called. It felt fast.
Deb Hopkins
We should have.
Interviewer/Reporter
A lot of people came out first
Matt Tanner
two years, we had really good turnouts. A lot of them, I didn't know who they were. And they showed up because they knew Dave.
Chris Tanner
They had great Dave stories.
Interviewer/Reporter
How do you think he'd want to be remembered?
Matt Tanner
Somebody that would give up himself to make somebody else's day or, or life better?

Dateline NBC – The Mushroom Mystery
Episode Date: July 28, 2026
Host: Lester Holt
Reporter: Blaine Alexander
In "The Mushroom Mystery," Dateline NBC delves into the chilling and highly unusual murder of David Fouts in rural Indiana. What first looked like a mysterious roadside death during the early days of the COVID pandemic evolves into a web of deception, hidden motives, a rare poisoning, and a twisted plot involving wild mushrooms. The investigation spotlights not only a rare murder method but also the manipulative and eccentric behavior of Fouts' wife, Katrina, and her close friend, Terry Hopkins.
“The Mushroom Mystery” reconstructs a convoluted murder case that is part true crime and part psychological thriller. Dateline NBC balances forensic detail, the strange use of a rare poison, and an exploration of human deceit. Although Katrina Fouts was acquitted of murder, her conviction for conspiracy and the tragic loss of David Fouts leave behind haunting questions about trust, manipulation, and justice.
