Welcome back to 48 Hours Postmortem. I'm your host Ann Marie Green and today we are talking to correspondent Peter Van Sant and field producer Kat Terfs about the case of John Blauvelt, a military recruiter found guilty of stabbing his young wife Katie in Simpsonville, South Carolina back in 2016. However, before authorities had enough evidence to arrest him for murder, he went on the run with his 17 year old girlfriend, Hannah Thompson. So, Peter, Kat, thank you so much for joining us.
Kat Terfs
Hi Ann Marie.
Peter Van Sant
Hi Ann Marie. Great to be back.
Ann Marie Green
And a reminder to everyone, if you haven't actually watched this 48 hours or listened to it, you can find it in your podcast fe just below this one. Go listen and then come on back so we can have this conversation. So I wanna start things off by talking about the weapon. It's a knife and it's not a particularly large knife. And I know when I saw it I thought you have to get so close to someone to kill them with this knife, it has to be sort of an intimate engagement. Peter, you were in the room with the murder weapon. I'm wondering what it was like. I know you've seen a lot of different sort of pieces of evidence in murder cases, but what was it like to be in the room with with this piece of evidence?
Peter Van Sant
It's a real solemn, heartbreaking moment. This is the weapon that was one of the last things that Katie Blauvelt saw on this earth. It was selected by her killer. This killer was a trained soldier he knew how to use knives. And Kinley ab, the prosecutor, she suggested to me that he knew this would be a painful death. And Blauvelt left the knife in her neck because we know now this was a revenge killing, that he did that on purpose.
Ann Marie Green
And, Kat, this was an important piece of evidence, obviously.
Kat Terfs
Right. It just shows how much force would have been used for that knife to actually break off.
Ann Marie Green
No DNA found on it, though.
Kat Terfs
So at trial, the defense argued that there was no DNA linking to John Blavelt, nothing at the scene that tied to him. And the prosecution said that there was DNA found under Katie's fingernails, but it was a partial match to John Blavelt. You could not conclusively say that that was John's DNA there.
Ann Marie Green
So this is another case where people are just not what they seem. And the thing with John is that he's not just in the military, he's a military recruiter. And I thought to myself, you know, you get that position because you have the ability to influence. You have the ability to connect with young people, to convince them that joining the military is going to be something beneficial for them. So, you know, of course, Katie finds John completely trustworthy. She's wooed by him, so much so that she actually enlists as well. Much to, I think, of Katie's mom. But, Peter, you spoke to Katie's mom a little bit about this, and this wasn't able to make it into the hour. So we want to play this sound.
Peter Van Sant
So was it. Did it strike you as odd that here John and Katie had found each other, there was this attraction, even some love, that he would encourage her to join the army where she could be posted in another part of the country. I mean, was there a plan here? Did you talk to John about this? No. I had no idea where that came from, what the plan was. Did it seem odd to you? It did, because I thought the same thing, that there's no telling word.
Ann Marie Green
And I didn't know if maybe he.
Peter Van Sant
Had planned on moving with her somewhere else or was he trying to get rid of her already? I don't have any idea.
Ann Marie Green
Here's the thing about him, is it wasn't just Katie who had fallen for him in a way, but he was a. An influential adult figure in the lives of other teenagers as well, including the girl who ends up being his girlfriend, Hannah Thompson. These teenagers are at his house hanging out.
Peter Van Sant
Allie Somerville, one of Katie's friends, told me that he partied with them. And it's shocking behavior.
Kat Terfs
John was in his late 20s and you know, these kids are 17. Peter. You know, you made a point about adults psychologically taking advantage of children.
Peter Van Sant
Yeah, yeah, absolutely. These are 17 year olds. And as a father of a bunch of kids, that's a very vulnerable age for people, and he just took advantage of that. I think a lot of these kids had a lot of independence as far as what we saw, and they enjoyed this adult kind of lifestyle that their parents were unaware of.
Ann Marie Green
Right, right. Yeah. There's got to be sort of a bit of a combination of a personality who looks for vulnerabilities in these kids. And then the kids that are vulnerable. I'm sure there are other kids who just thought he was weird and, you know, never went to his house. So, Peter, you actually. You spoke to Captain Cheryl Schofield. You spoke outside of the house there.
Peter Van Sant
Yes, I frightened her.
Ann Marie Green
Why did they use a wide angle lens?
Peter Van Sant
I don't know. You watch it in the show. I look like Lurch. I'm like nine feet tall.
Ann Marie Green
But you are nine feet tall. You do not look like Lurch. But Peter Van Santa is a very tall man.
Peter Van Sant
I'm six foot three. That's not too tall, but, yeah, it looks silly. We had a good laugh in the screening room when we took a look at that. But she was a terrific investigator. Her heart was so into solving this case. The kind of people you want to have in law enforcement.
Ann Marie Green
Let's talk about this investigation then. You know, as far as John Blavelt's demeanor, he's told about this death and he's brought in for questioning. I know 48 hours viewers were analyzing sort of every second, every move that he made, the words that he chose. He really shifts from, like, crying to being unemotional. I was trying so hard to see whether or not there were real tears or, you know, what. What did you guys make of it? Because I know you got a chance to watch more of the interrogation than we did.
Kat Terfs
Okay, well, there was a lot going on there. In the beginning, he did appear to be distressed. I mean, we don't know what's going on in his head, but he looked emotional. He looked like he was crying. He put his head in his hands, but as the interview progressed, he was laughing. At points. The cop said he was very, like, nonchalant about, you know, answering questions after being informed that his wife had just. Had just been murdered.
Ann Marie Green
And then he takes off, much to the frustration of law enforcement. I think a lot of people will wonder, hey, if you're under suspicion for murder, how is it that you're Able to just kind of leave like that. But if you're not charged, then there's, there's no reason to hold you.
Peter Van Sant
Right. And you know, they, there is a level of threshold of evidence that has to be presented to a judge to get a warrant. They didn't quite have that at that point. They had this interview which raised their suspicions greatly. They, they knew the body, where the body was found was a place where kids had hung out and partied with John. So they had pieces of this puzzle, but they just didn't quite have enough. And Blauvelt takes off and he takes off with a 17 year old girl, Hannah Thompson with them. They're, they're heading out on the road. And this is where a 17 year old, I think can be brought into a circumstance psychologically from an adult of his age and his sophistication and his training and all of that. I think she was a real victim at this point being pull into this horrible situation with a man. How much she knew at that point that he had committed murder. She learned a lot more later on was the whole thing was just a tragic situation. But off she goes in his car and they're heading west.
Ann Marie Green
Out of curiosity, did any of the investigators speculate about why he would even take Hannah with him? You would think that bringing Hannah would just increase the likelihood of him eventually getting caught.
Peter Van Sant
Well, they supposedly were in love at that point. She told authorities later that she was in love with him.
Kat Terfs
She said that she trusted him, she felt like he would keep her safe. And I think it was suggested to her that it was going to be an adventure. You know, at first it seemed fun, but as time on the run went on, that very quickly wore off.
Peter Van Sant
Did it ever. I mean, I drove several thousand miles and they got up the Pacific Northwest and he gets his car stuck in the mud near Walla Walla, Washington. You probably remember that from Bugs Bunny cartoons. And they have to walk away and they, they live their lives basically as homeless people. They were panhandling to get money for food. They were sleeping outside quite a bit. And about a month into this, into this journey, he just walks away, according to her. And she calls.
Ann Marie Green
Oh, sheet honey, chill.
Kat Terfs
It's just laundry.
Ann Marie Green
Not that I'm talking about these arm and hammer power sheets. All the power of arm and hammer laundry detergent and a convenient tossable sheet. Oh, sheet. That's what I'm saying.
Kat Terfs
And arm and hammer power sheets deliver an effective clean at a great price. Think of all the laundry we'll do.

And all the Money we'll save.

Oh, sheet, arm and hammer. More power to you.

Ann Marie Green
Welcome back, everyone. So there's another irony in the case and it comes up when John goes on the run. Peter, you have a really great exchange with a US Marshal where he makes the point that John had training with the army and the government provided this training to him, ironically. And then you sort of interject, right, saying the training was to, to.
Peter Van Sant
To avoid us. Because these U.S. marshals, they're extraordinary investigators. I've done a whole host of, of hours with these guys and there's something about them that they tend to be very calm. Their personalities, you know, don't dominate a room, but they are so fixated. If I could do a quick, a quick story. What they remind me of when I was, when I was young, when I was a teenager, we got a couple of kittens at our house. We had one named Charlie and we decided to give Charlie away. And, and my mother found a family and drove Charlie three miles away to this household. Next day, the family says, charlie's gone. Two days later, Charlie shows up at our house. That's a U.S. marshal. They just suddenly appear out of the blue, like, how did that happen? And these guys are patient and they find these little clues and they hunt people down in the confidence level. And it may take some years. I've had them find a man in a remote Mexican village. And in this case, John Blauvelt had used all of his training and brilliantly ended up in Medford, Oregon with a woman who had no idea who he was and was living low and thought he. I'm sure that there was no way they would find him.
Ann Marie Green
Yeah, I too am also a big fan of the Marshalls. I think that the description that you presented was just so spot on and something that kind of jumped out at me in the hour that I thought would make their job challenging. I don't know if you guys noticed this or not, but I felt like BL looked different in almost Every picture you showed, like, there was one picture where he's got a knit cap. And I thought to myself, I could have sworn I dated that guy once because he looked like an ex of mine. He looks like you put ten pounds on him. He looks different. You put a beard on him, he looks completely different.
Peter Van Sant
Ah. But he had one identifying feature he could not shed that he could not change. And that was a pirate tattoo tattoo that was on his arm. He had other tattoos as well. Yeah, but when he went in for his interview, that was on camera. The. The interview right before he fled, he wore a short sleeve shirt. Imagine if he'd worn a long sleeve shirt. And they didn't know this, but there they spotted the. The tattoos. And these marshals, they focus in on this. We have an identifier, but I just.
Ann Marie Green
Thought, you know, it's like 101. Tattoos are identifiable. You wear long sleeves, you cover it with makeup. You do something. So even though he had all this great training, he also didn't implement everything as well as he could.
Kat Terfs
I suppose he definitely could have worn long sleeve clothing at the time he did the interview. But the marshals really were very thorough. You know, investigators were talking to Hannah over the years, and Hannah actually provided some information that helped lead to Blavel. It. It was difficult for them, you know, to get her to trust them. But as the, you know, investigators told us, as time went on and she has, she's matured and she's got time away from Blauvelt, they felt that really helped, you know, and then we were also told that she has said that she wanted to do the right thing.
Ann Marie Green
Mm.
Peter Van Sant
It's tough, Anne Marie. Cause they know she's going to be their star witness in any court case against Blauvelt. And so it is a delicate dance here.
Kat Terfs
But it's important to note that authorities don't think that Hannah Thompson was actually there when Katie was murdered.
Ann Marie Green
Right. So, yes, we find out that, you know, six years after Blauvel fled, the U.S. marshals are able to actually track him down to where he's living with his new girlfriend in Medford, Oregon. How did they actually track him down, though?
Kat Terfs
You know, investigators were talking to Hannah over the years, and Hannah said that he had told her that he had had this long term girlfriend who he. And investigators were able to use that information and really hone in. They found a phone number that was an old number for Blauvelt, and they saw that that number had been used to text this other woman who they. They weren't sure who it was at the time, but they found an address for that woman and it ended up being that girlfriend. And then they just started staking out the house. And then, you know, it was that.
Peter Van Sant
Pirate tattoo and where they were connecting some of the dots here. Remember his truck got stuck in the mud in Washington. When Hannah called her parents, she was in Oregon. And so when they discovered on this phone that he'd been texting this woman, that woman lived in Medford, Oregon. So geographically, you know, the noose was tightening. They said this must be the area that he is in. And don't forget, at this point, he was Ben Klein. He was not John Blauvelt. He had changed his name, which would make it even more difficult to try to identify this guy. But they were able to get her address and she. Upstanding woman in the community, a full time job. She was the breadwinner in the family. And John was sort of a stay at home partner for her. In fact, when they observed him one day, I think he was putting together, was it a portable swimming pool out on the yard? Do you remember that cat?
Kat Terfs
Yeah. It was a hot day and he was coming outside with this kiddie pool and he was shirtless. And so the marshals were able to see that. That tattoo on him and.
Peter Van Sant
And he looked so different. He had a beard, long hair, he'd put on some weight. Somebody that I wouldn't have recognized him except for Hardy Hard Hard, that tattoo.
Ann Marie Green
So this new girlfriend is shocked. She doesn't know anything about his past, but I thought to myself, she says that he hardly ever leaves the house. He does, you know, a handful of odd jobs.
Kat Terfs
Yeah. So she said that he had told her that he didn't get along with his family and she just kind of thought he was a hippie. He didn't have social media as far as she knew. He told her his name was Ben Klein, and she said he was a very good liar. And, you know, she unfortunately fell for it.
Peter Van Sant
During the course of our show, we played some of the audio that was recorded at the scene after the takedown of John Blauvelt at that woman's property right outside her front door. And one of the marshals interviewed her and we have more sound from that talk. That just gives you a sense of the shock that she was experiencing to learn that her partner in life was a killer. I'm just trying to get how he was able to be here, hidden for so long.
Kat Terfs
He just said that he didn't want anything to do with.
Peter Van Sant
Did he ever go out?
Kat Terfs
No, he said it was mainly he would chalk it up to the ptsd. He didn't like to be around crowds he didn't like. So I just, I thought it was just ptsd.
Ann Marie Green
I mean, you can see that she's completely broken up about this.
Peter Van Sant
Yeah. And as she learned more details, just imagine that, that horror ride.
Ann Marie Green
So the other really interesting element to this case is that authorities, after they track him down, they discover a journal. And he's been writing in this thing now for quite a while. At one point, there's the phrase, I did it. And the prosecution argues that this is him admitting that he killed his wife.
Kat Terfs
Yeah. So he actually had been keeping that journal since he first went on the run. And he would write about his day to day happenings, camping, how he was spending his time. And there were letters in there between, between John and Hannah where she had written in the journal as well when she was out there with him. And they wrote lovingly to each other. And there was a letter where he wrote to her after she left, where he said that he. He was sorry to have allegedly involved her.
Ann Marie Green
So the trial lasts only four days. He's found guilty, he's sentenced to life in prison. Where do things go from here with the case?
Peter Van Sant
Well, he's going to appeal his conviction and then, Kat, you want to talk about what's happening with Hannah?
Kat Terfs
Hannah is facing five felonies and her fate is going to be up to a judge. There's no trial date set yet, but a judge will decide what will happen to Hannah.
Peter Van Sant
And we should note that Hannah has pleaded not guilty to the charges against her.
Ann Marie Green
Well, you know, it was a great hour. I also sort of. It was heartbreaking. Cause I thought to myself, you know, a lot of us get into relationships that are not meant to last. They just don't work out and you leave. And Katie would have left, I mean, literally after the honeymoon. The writing was on the wall. And because she crossed paths with the wrong person, it has this tragic, tragic end. And it's such a shame.
Peter Van Sant
She was a sweetheart of a young woman. Those who knew her, she loved animals. She just wanted to get married. She wanted to have a family. Just the shock of what she had hoped for and what her life became, how it ended in this tragic murder is just heartbreaking.
Ann Marie Green
Definitely. Well, Peter and Kat, thank you so much. Really appreciate talking to you.
Kat Terfs
Thanks.
Peter Van Sant
Thank you, Annemarie.

Summary of "48 Hours" Episode: Post Mortem | Cati Blauvelt: Death of a Soldier’s Wife
Introduction
In the Post Mortem episode titled Cati Blauvelt: Death of a Soldier’s Wife, CBS News’ 48 Hours delves deeply into the harrowing case of John Blauvelt, a military recruiter convicted of murdering his wife, Katie Blauvelt, in Simpsonville, South Carolina, in 2016. Hosted by Anne-Marie Green, the episode features correspondents Peter Van Sant and field producer Kat Terfs as they dissect the intricate details of the case, exploring the evidence, motivations, and the subsequent manhunt that led to John’s eventual capture.
The Crime and the Murder Weapon
The episode opens with a poignant examination of the murder weapon—a seemingly ordinary knife used by John Blauvelt to fatally stab his wife.
Peter Van Sant (02:27) describes the emotional weight of handling the weapon:
“It's a real solemn, heartbreaking moment. This is the weapon that was one of the last things that Katie Blauvelt saw on this earth. It was selected by her killer. This killer was a trained soldier he knew how to use knives.”
Anne-Marie Green (03:05) highlights the prosecution’s argument regarding the weapon:
“The prosecution said that there was DNA found under Katie's fingernails, but it was a partial match to John Blauvelt. You could not conclusively say that that was John's DNA there.”
This evidence underscored the intimate and calculated nature of the crime, pointing to a premeditated act of revenge.
John Blauvelt’s Persona and Influence
John Blauvelt was not just a military recruiter; he was an influential figure among teenagers, which added complexity to the case. His ability to connect with young individuals made him a trusted figure, particularly pointed out by Anne-Marie Green:
“Of course, Katie finds John completely trustworthy. She's wooed by him, so much so that she actually enlists as well, much to Katie's mom.”
Kat Terfs (05:13) observes the exploitative nature of John’s relationships:
“John was in his late 20s and you know, these kids are 17. You know, you made a point about adults psychologically taking advantage of children.”
This dynamic is critical in understanding how John not only manipulated his spouse but also influenced other young lives, leading to tragic consequences.
The Escape and the Manhunt
After the murder, with insufficient evidence to charge him immediately, John fled with his 17-year-old girlfriend, Hannah Thompson. Their flight took them across several states, showcasing John's military training and tactical skills.
Peter Van Sant (07:07) explains the immediate aftermath:
“They just didn't quite have enough. And Blauvelt takes off and he takes off with a 17-year-old girl, Hannah Thompson with them. They're heading out on the road.”
As they traveled, they lived as transient, homeless individuals, panhandling for food and shelter. However, about a month into their escape, John left Hannah alone, a decision that would later prove pivotal in his capture.
Tracking John Blauvelt
The U.S. Marshals' relentless pursuit eventually led them to Medford, Oregon, where John had assumed a new identity as Ben Klein. Key factors in his capture included:
Identifying Features: Despite several changes in appearance, John's distinctive pirate tattoo remained a crucial identifier.
Peter Van Sant (13:32) remarks:
“But he had one identifying feature he could not shed that he could not change. And that was a pirate tattoo tattoo that was on his arm.”
Information from Hannah Thompson: Over the years, Hannah provided investigators with critical information that helped narrow down John's whereabouts.
Kat Terfs (15:26) explains:
“Investigators were talking to Hannah over the years, and Hannah said that he had told her that he had had this long term girlfriend who he.”
These combined efforts culminated in John’s discovery and apprehension near his new residence.
The Capture and Aftermath
Upon locating John Blauvelt in Medford, Oregon, authorities executed the takedown swiftly. The encounter revealed the stark contrast between his former and current self—his beard, weight gain, and changed appearance nearly concealed his identity.
Peter Van Sant (17:08) reflects on the marshals' effectiveness:
“They have been able to track him down to where he's living with his new girlfriend in Medford, Oregon.”
The confrontation was shocking for John's new girlfriend, who was unaware of his violent past. This led to emotional turmoil and disbelief at the revelation of her partner’s true identity.
Hannah Thompson’s Role and Legal Consequences
Hannah Thompson, the 17-year-old who fled with John, faced her own set of challenges as authorities scrutinized her involvement. Despite her young age, she was implicated in five felonies related to the case.
Kat Terfs (20:07) outlines Hannah’s legal situation:
“Hannah has pleaded not guilty to the charges against her.”
Her testimony remains crucial, as she is expected to be the star witness in the trial against John Blauvelt. The legal proceedings for Hannah are pending, with no trial date set at the time of the episode’s release.
The Trial and Sentencing
John Blauvelt’s trial was swift, lasting only four days. The prosecution's case was bolstered by the journal John kept during his time on the run, which included a phrase he wrote—“I did it”—interpreted as an admission of guilt.
Kat Terfs (19:20) discusses the journal's significance:
“He would write about his day to day happenings, camping, how he was spending his time... and there was a letter where he wrote to her after she left, where he said that he was sorry to have allegedly involved her.”
Ultimately, John was found guilty and sentenced to life in prison. He plans to appeal his conviction, seeking to overturn the decision, while Hannah's fate remains uncertain, pending judicial review.
Conclusions and Reflections
The episode concludes with reflections on the tragic loss of Katie Blauvelt and the profound impact of John’s actions on those around him. Anne-Marie Green poignantly summarizes the personal devastation:
“Katie would have left, I mean, literally after the honeymoon. The writing was on the wall. And because she crossed paths with the wrong person, it has this tragic, tragic end. And it's such a shame.”
Peter Van Sant (20:53) adds:
“She was a sweetheart of a young woman. Those who knew her, she loved animals. She just wanted to get married. She wanted to have a family. Just the shock of what she had hoped for and what her life became, how it ended in this tragic murder is just heartbreaking.”
The episode serves as a sobering reminder of the complexities surrounding criminal investigations, the vulnerabilities exploited by manipulators, and the enduring quest for justice.
