Ann Marie Green
Welcome back to Postmortem. I'm your host Ann Marie Green and I'm joined by 48 Hours correspondent Erin Moriarty. We're going to be discussing the murder of 35 year old Jeannie Chiles. She was stabbed over 60 times in her Minnesota high rise apartment in 1993. Her case went unsolved for over two decades until advances in investigative genetic genealogy led authorities to arrest a local businessman and father. His name is Jerry Westrom. Aaron, thanks again for joining us.
Erin Moriarty
Oh, I'm really grateful to be here because this is one of those stories. People who love forensics love this story.
Ann Marie Green
We want to remind everyone, of course, if you haven't listened to this hour, head on over to your feed. You'll find this episode of 48 Hours right above this one. Go listen and then come on back and we can talk about it. When I started watching this, the case reminded me of actually the first 48 hours I ever did several years ago. It was the case of Angie Dodge, a teenager, an 18 year old, who was killed in her brand new apartment. And the case went unsolved for many, many years until they used genetic genealogy to track down her killer. It was kind of newish then. This is a very similar case, but. But the thing about this case is, you know, you think you find the DNA, you find the match, it's a home run. But in this case, in the apartment, there was a lot of DNA. So not necessarily a home run.
Erin Moriarty
No. What's so interesting is I think jurors sometimes think that it's a slam dunk when there is DNA that has been obtained through genetic genealogy. But the truth is, DNA, if it is collected and tested properly, it could show that somebody was there, but it can't tell you when they were there. And in this case, this case, as you said, emory, happened in 1993. That was when DNA was in its infancy, at least, being used as a investigative tool. And so they did collect DNA and they collected those bloody footprints that are just so important in this case. But the DNA didn't match anyone back then. They did have a person of interest. She was living with a boyfriend, Arthur Gray, but he had an alibi. He was out of town that weekend. And they took those unknown bloody footprints and compared them to Arthur Gray and said that they did not belong to him. So the case kind of went cold. And then in 2015, just about two decades later, you know, there were so many advances in DNA technology that they did more tests. And I thought this was really interesting. As you pointed out, Emory, there was a lot of DNA there in that apartment. Yeah. According to police reports, Jeannie was a sex worker, and there had been men in that apartment. But what was interesting is that they found one unknown profile, the specific that was not just in the bedroom, but also in the bathroom on a towel. And because investigators believe that the killer might have cleaned up in the bathroom, that was significant to them. And so that is the DNA that belonged to Jerry Westrom. But all they had at that point, really, is the idea that Jerry had been in that apartment at some point.
Ann Marie Green
Right. Because just because DNA is found, you can't tell when that DNA was deposited. Right?
Erin Moriarty
No, you cannot. And that's why in this case, those bloody footprints became so important. You know, normally it would be a genetic genealogy case. This was a bloody footprint case. And the prosecution said whoever left their footprints in her blood had to be either there at the time of the murder or right afterwards. And so if those footprints match the person whose DNA was found in that apartment. That was a pretty good indication that that person could be the killer.
Ann Marie Green
Now, I think at this point, one of the most, I guess, famous investigations that was solved because of genetic genealogy was the case of the Golden State killer, Joseph James DeAngelo. Were the investigators inspired by that case, and is that why they kind of went down that route?
Erin Moriarty
You know, that case inspired investigators all over the country. Yes. And they were inspired even to use the same genealogist, Barbara Ray Venter. I had met her on a story I was doing for Sunday Morning, and she's such an interesting woman. She was a patent lawyer, but she also had a PhD in biology, and she loved to do. Because this woman has this amazing brain. Her hobby was to do these family trees, and that's how she got involved in the Golden State Killer case. So now she does these cases. And she took that profile that I mentioned that had been found both in the bedroom and the bathroom, and she uploaded it to the genealogy sites, including MyHeritage.com, and she was able. Able to build out a family tree and came up with two suspects who happened to be brothers. And then she picked Jerry because the DNA profile indicated that it belonged to someone with brown eyes. And Jerry Westrom had brown eyes. But more important, probably, I think, for investigators, was Jerry Westrom had a history of soliciting sex workers, and so that made him a suspect in this case. And remember, it's just. It's just a piece of evidence at this point. You know, at this point, Jerry Westrom now is just a suspect. Right, because they can't bring any charges based on what Barbara Ray Venter finds out. She gives them these names, and then she has no idea what happens after that till they call her and say whether they've arrested a person or not. So, you know, what they have to do at that point is they've got to get a real DNA sample from that person and then see if that matches the unknown DNA in the crime scene. They have to do that, or they can't take this case to court.
Ann Marie Green
So therein lies the challenge. They have to somehow get a DNA sample from Jerry. And I thought it was really interesting in the Hour how they talked about, you know, a mouth sample, a saliva sample is better than anything else. And this is the first time I actually considered why they want mouth swabs, why they always look for, you know, something a suspect may have put in their mouth. A drink. But they go, the FBI agents in 2019, they go all the way to Wisconsin to track him down at a hockey game. Why do they have to go that far?
Erin Moriarty
Well, so, yes, you're right. He's living just right outside Minneapolis in Isanti. But he is a devoted hockey dad. And I think they believed that if they followed him to Wisconsin, where he was going with his family to see his daughter play hockey. You know, you eat, you're out at a hockey game. So you've got these two investigators who are following him, like, right behind, but they don't want him to know, because what if they're wrong? They don't want to be seen. They're staying in the same hotel as Jerry and his wife are staying. I mean, they even went. It just is so interesting. After he checked out of his room, they went into his room. Now, how are they going to know that it was his DNA that he left on something? But they did, just in case they could find something that they thought connected just to him. So it takes time, and they're frustrated. So they finally follow him to this game. According to Agent Bokers, they follow him to this game, and they finally see him wipe his mouth with a napkin, and they bring it back to the lab. And according to Andrea Fayer, who was the forensic scientist who tested it, matched the unknown DNA sample from the crime scene. So they've got more than a suspect. They've got someone they're about to charge.
Listener/Interviewer
Wow.
Ann Marie Green
And so they get the DNA sample, and they make an arrest. How did Jeannie's family react to hearing about who the suspect was?
Erin Moriarty
Well, with a lot of surprise, number one, you know, it had been so long. This was February 2019. Jeannie had been killed 1993. They did not tell them that they were looking at someone. So this came out of the blue. But I think more important, especially for Jeannie's sister Cindy, they live in Isanti, and that's where Jerry Westrom lives. Jerry ran Westrom's Corner, which had a shop and a gas station, and everybody went there. Her kids knew his kids. I mean, it was shocking. Jeannie's sister, and I should point out, I think this is very important. Yes, he might have had brown eyes. Yes, he may have had a history of soliciting sex workers, but he did not have a history of violence. And if you remember, Emory, Jeannie was killed brutally. And so I think it came as a big shock to Cindy and her.

Ann Marie Green
Welcome back. In February of 2019, Jerry Westrom was arrested when he was 52 years old and he was charged with the murder of Jeannie Chiles. Now, police questioned him for 11 minutes before he asked for an attorney. I want to play a clip of that interview that didn't make it into the show.
Listener/Interviewer
Do you know we have your DNA? I assume so. Okay, so is there any, can you think of anything? Man, this has been a long time ago. This is a pretty significant event. When you agree, I mean, first and. Sorry, yeah. The person involved in this going to remember, don't you think? Absolutely, yeah. And so that's kind of what we're, we're wondering if you have any of that kind of knowledge.
Ann Marie Green
What was he like during that interrogation?
Erin Moriarty
I mean, he doesn't seem to be upset. You know, why isn't he asking why he's there or not saying what we all think he would say. I didn't do anything like that.
Ann Marie Green
I would say so, considering the circumstances.
Erin Moriarty
But when we spoke with our legal consultant, Julie Rendelman, she does point out that you really can't judge somebody's affect. You know, we don't really know what's going on through his head.
Ann Marie Green
So this case also had a really sort of interesting piece of evidence that you talked about a little bit earlier, these bloody footprints. And it was the focus for investigators. And at first I thought, oh, what a unique and perfect piece of evidence. But then afterwards I thought, but how do you, what do you compare that to? There's no footprint database like there is for fingerprints. So how do you even use this evidence?
Erin Moriarty
That was so interesting, Emery? This was the first one for me, as it seemed to be for the investigators. But you know, remember these were actually recorded back in 1993. They were photographed. There were seven that they had labeled. So what was interesting, we had two experts. So we had the expert for the state and then we had an expert that had been hired by the defense, and the expert for the state said that four of those were suitable for comparison. And he decided, and he testified as such, that four of those prints belonged to Jerry Westrom, that Jerry Westrom was the one who left them there. That is so damaging, as you can imagine, because we know his DNA is in that apartment. But now it looks like that these bloody prints also belong to him. But then you have the expert that had been hired by the defense, and she is an expert who teaches in waterville, Maine, Alicia McCarthy. And she did the same work as the state expert, but she said that she only found one of those prints, E2. It was labeled E2 as suitable for comparison. She says that the state expert was not right about those other three, that you could not analyze and compare those other three, just E2. But what matters in this case is she also found that the print, which is one right below the big toe of the left foot, just this small area, she says, was left by Jerry Westrom. So as you can imagine, Anne Marie, when the defense found out that she was agreeing, at least on that one part, that it belonged to Jerry Westrom, the defense dropped her, did not want her to testify for them. But the state said, please testify for us. She did. And I think that was very significant for the jury. So what you have is you do have the DNA, the genetic genealogy DNA that seems to place him in that apartment. And you have the area right below the big toe of the left foot that seems to also place Jerry Westrom in her blood on the day she was murdered. And then you have that interview where he doesn't seem to show a lot of emotion. But that's. That really kind of describes the case against Jerry Westrom.
Ann Marie Green
In August of 2022, Jerry Westrom went on trial for Jeannie Childs murder. Now, the jury heard from a defense witness who told police that she saw Jeannie Chiles with a blonde man wearing a trench coat on the day she was murdered. But I'm wondering if there were any other suspects that the jury did not get a chance to hear about.
Erin Moriarty
So I had mentioned Arthur Gray. The judge did allow the defense to raise Arthur Gray. He was living in the apartment. Jeannie, they did have a history of abuse. She had filed a police report, and his hair was found on her hand. But he had an alibi. But there were some really interesting other possible people of interest. So they found blood right in the stairwell that belonged to a guy named John Eswa. And so they interviewed John Eswein. I should point out, none of his DNA was found in the apartment, but his blood was found in the stairwell. And they interview him, and he's a very friendly guy, but when they compared his feet to those unknown bloody footprints, that came out inconclusive. The jury never heard any of that. And a more interesting person is James Luther Carlton.
Listener/Interviewer
Hmm.
Erin Moriarty
So James Luther Carlton was convicted of killing a woman a year later, Jody Dover, in her apartment. And here's why. It's eerily similar. In Jody Dover's murder, there were also bloody footprints found. And that's so unusual. And one of those footprints was found to belong to Carlton. We do not know whether Carlton was at all investigated or talked to at the time in this case, but he's now serving a life sentence for Jody Dover's murder. So the jury, again, did not hear anything about Carlton or John S. Y.
Ann Marie Green
And so ultimately, the jury does find Jerry Westrom guilty of murder in the first and second degrees. And then on September 9, 2022, he's sentenced to life in prison. In 2024, the Minnesota Supreme Court reversed Westrom's second degree conviction, but it upheld the first degree murder conviction. I'm just curious about why they reversed the second degree conviction.
Erin Moriarty
Well, every state is different. You know, even whether you have a first degree or second degree murder is different by state, by state. And I'm just gonna read to you what the ruling is, because I thought this was interesting, that according to the ruling in the state of Minnesota, a defendant may be convicted of either the crime charge, which was murder or an included offense, but not both. And so every lesser degree of murder is an included offense. So they decided that. That second degree murder was an included. So he could be convicted of first degree, but not both, not the included offense. So that's why they reversed it. But he's, you know, he's remaining in prison on first degree.
Ann Marie Green
Right, Right. The punishment is. Is the punishment. And he's going to be behind bars for a really long time, I think. I know. For me, the most frustrating part of this story, though, is that we don't get to hear a why? Because he's not talking. And he didn't testify.
Erin Moriarty
And there was no motive. They did not present a motive. You know, there was a. In one of her date books, there was a Jerry, but, you know, nobody knows who that Jerry was. But otherwise nobody remembers him with her. Jerry just didn't come up. But no, no motive in this case, and he didn't take the stand.
Ann Marie Green
So even though, I mean, we really don't know what happened in that apartment or why it happened. The fact that he was convicted after 25 odd years. Does the family feel like they've received closure, that there's justice? Or are there so many still unanswered questions that there can never be closure?
Erin Moriarty
I mean, they both have said this to Jeannie's mom and her sister. They do trust the system. They believe that he did kill Jeannie. I don't think her mom will ever stop grieving. She read to us this beautiful letter that she had written her daughter once afterwards. So sorry that she couldn't have said all of these things to her daughter before she died. So they are left with their grief, but at least they no longer in their minds have to worry about who it was they feel they now know who killed Jeannie Childs.
Ann Marie Green
Erin, Another fascinating story. I learned more about DNA and I thought I knew a lot. I learned about footprints and whether or not they make for good evidence. And thanks for joining us.

Host: Anne-Marie Green
Guest: Erin Moriarty (48 Hours Correspondent)
Airdate: July 21, 2026
In this episode of “Post Mortem,” host Anne-Marie Green and correspondent Erin Moriarty dive deep into the murder of Jeannie Chiles, a Minnesota woman brutally stabbed over 60 times in her apartment in 1993. The case went unsolved for more than two decades before new forensics and investigative genetic genealogy led authorities to arrest Jerry Westrom. The episode places a spotlight on the complex interplay between evolving forensic science, the persistence of investigators, and the limitations of physical evidence—specifically, the pivotal role of bloody footprints.
[01:41 - 03:17]
Old-School Forensics:
The 1993 murder was investigated when DNA testing was still a developing technology. Investigators preserved DNA evidence and documented bloody footprints from the scene, but there was no match at the time.
Overwhelming DNA:
The DNA in Jeannie's apartment wasn't a clear home run; the victim, a sex worker, entertained several men, complicating the evidence.
“You think you find the DNA, you find the match, it’s a home run. But in this case... there was a lot of DNA. So not necessarily a home run.” – Anne-Marie Green [02:24]
Significance Shift:
Forensic science advanced substantially by 2015, allowing more detailed analysis. The breakthrough came with an unknown DNA profile found not just in the bedroom but also on a bathroom towel—where it was presumed the killer cleaned up.
“What was interesting is that they found one unknown profile... that was not just in the bedroom, but also in the bathroom on a towel.” – Erin Moriarty [03:17]
[03:17 - 05:55]
DNA’s Story Telling Limit:
DNA can demonstrate presence but cannot pinpoint timing.
“DNA... could show that somebody was there, but it can't tell you when they were there.” – Erin Moriarty [03:17]
Bloody Footprint as Key:
The prosecution focused on bloody footprints in the victim’s blood, arguing whoever left them was either present at, or immediately after, the murder.
“Whoever left their footprints in her blood had to be either there at the time of the murder or right afterwards.” – Erin Moriarty [05:22]
[05:55 - 08:09]
Genealogy Inspiration:
Inspired by the Golden State Killer case, authorities used genetic genealogy, enlisting renowned genealogist Barbara Rae-Venter.
“They were inspired even to use the same genealogist, Barbara Ray Venter.” – Erin Moriarty [06:12]
Building the Family Tree:
The DNA profile was uploaded to genealogy sites. The search narrowed to two brothers, with Jerry Westrom fitting the profile based on eye color and history of soliciting sex workers.
Confirming the Suspect:
After Barbara Rae-Venter handed over the suspects’ names, law enforcement needed a direct DNA sample for a legal match.
[08:09 - 10:01]
Covert Sample Collection:
FBI agents tracked Westrom to his daughter's hockey game in Wisconsin, tailing him discreetly. They retrieved a napkin he used, which forensics matched to the DNA in the apartment.
“They finally see him wipe his mouth with a napkin, and they bring it back to the lab... [it] matched the unknown DNA sample from the crime scene.” – Erin Moriarty [09:00]
[10:01 - 11:20]
Shocking News:
Jeannie’s family—especially her sister Cindy—was stunned. The suspect was a local businessman whose children knew the family.
“Her kids knew his kids. I mean, it was shocking.” – Erin Moriarty [10:57]
Important Context:
Westrom had no documented violent history, just solicitation of sex workers.
[12:24 - 13:30]
Interrogation Clip:
Police confronted Westrom with the DNA evidence; he remained calm, never denied involvement, but quickly asked for a lawyer.
“He doesn’t seem to be upset. You know, why isn’t he asking why he’s there or... saying what we all think he would say: ‘I didn’t do anything like that.’” – Erin Moriarty [13:16]
[13:43 - 16:44]
How Do You Compare a Footprint?
Unlike fingerprints, there's no searchable database for footprints. Seven bloody prints were documented.
Expert Testimony:
“She says... the print... was left by Jerry Westrom. So... the defense dropped her, did not want her to testify for them. But the state said, please testify for us.” – Erin Moriarty [15:35]
Stack of Evidence:
Combination of DNA and bloodied footprint under Jeannie’s toenail pointed to Westrom, alongside his subdued reaction in police interviews.
[16:44 - 18:51]
Arthur Gray:
Jeannie’s boyfriend with past domestic violence allegations; alibi checked out.
John Eswa:
His blood in the stairwell, but no connection to the apartment; inconclusive footprint match. Jury never heard of this.
James Luther Carlton:
Convicted of a strikingly similar murder the following year, footprints left at both crime scenes. Jury never learned of his possible relevance.
“One of those footprints was found to belong to Carlton. We do not know whether Carlton was at all investigated or talked to at the time in this case...” – Erin Moriarty [18:06]
[18:51 - 20:16]
Conviction:
Westrom was convicted of first and second degree murder, sentenced to life (September 2022). In 2024, the second-degree conviction was overturned—Minnesota law only permits conviction on the highest charge, not included lesser charges.
“Every lesser degree of murder is an included offense. So... he could be convicted of first degree, but not both...” – Erin Moriarty [19:18]
No Stated Motive:
Neither prosecution nor Westrom provided a clear motive; his silence and lack of testimony left questions unresolved.
“There was no motive. They did not present a motive.” – Erin Moriarty [20:16]
[20:38 - 21:35]
Family’s Acceptance:
While the family feels justice has been served, the absence of answers regarding motive continues to haunt them.
“They do trust the system. They believe that he did kill Jeannie. I don't think her mom will ever stop grieving. ...They are left with their grief, but at least they... no longer have to worry about who it was.” – Erin Moriarty [20:58]
On the Complexity of DNA Evidence:
“Jurors sometimes think that it’s a slam dunk when there is DNA... But the truth is, DNA... can’t tell you when they were there.”
— Erin Moriarty [03:17]
On Tracking Down Jerry Westrom:
“You’ve got these two investigators who are following him, like, right behind, but they don’t want him to know, because what if they’re wrong?”
— Erin Moriarty [08:41]
On Footprint Evidence:
“There’s no footprint database like there is for fingerprints... So how do you even use this evidence?”
— Anne-Marie Green [13:43]
Defense’s Own Witness Sinks Their Case:
“She says... the print... was left by Jerry Westrom. So... the defense dropped her, did not want her to testify for them. But the state said, please testify for us.”
— Erin Moriarty [15:35]
On the Family’s Pain:
“She read to us this beautiful letter that she had written her daughter... So they are left with their grief, but... they no longer... have to worry about who it was.”
— Erin Moriarty [20:58]
For listeners interested in cold cases, the evolution of forensic science, and the human costs of unsolved crimes, this episode offers a compelling, nuanced breakdown of a case where technology and dogged police work intersected to secure justice—though not all answers.
