Foreign welcome back to Postmortem. I'm your host Ann Marie Green. And today we're discussing the mysterious death of Kenneth Vandridge. He was found murdered inside a Parking garage on January 27, 2023 in Hillsborough, Oregon. When police reviewed the security footage from that garage, they noticed a masked man spray painting the cameras, wearing a disguise to obscure his identity. But incredibly, as we're going to discuss, they were still able to find the killer. So joining me now to discuss this is 48 Hours correspondent Natalie Morales. It's a fascinating case. Thanks for joining us again, Natalie.
Natalie Morales
She sure is fascinating. Good to be with you, Annemarie.
Ann Marie Green
As usual, a reminder to everyone, if you haven't already listened to this episode of 48 Hours, head on over to your podcast feed. You'll find it just below this one. Listen to the hour and then come on back for this conversation. All right, let's get into it. The victim here is Kenneth Vandridge. He also went by Kenny and investigators discovered his body in the driver's seat of his car in a parking garage run by the tech company Intel. The garage is located on massive campus, very large campus of one of Intel's production facilities. This is where he's been working as a contract pipe fitter. Natalie, you actually went to the garage and I just want to get a sense of just how big is the garage? What was it like there? How many cameras are we talking about? Was it like finding a needle in a haystack?
Natalie Morales
You know, this was Actually, almost the opposite of a needle in a haystack when you think about it. I mean, this is a huge tech company, intel, we're talking the maker of, of all those incredible super speedy chips that we all use on our computers. But, you know, this is an area, the garage especially, where there are loads of security cameras all the way inside the garage as well as on the campus. It's an area that is well covered. There is a lot of security. So obviously, the garage of a tech company like intel is a very interesting choice and place to commit a murder.
Ann Marie Green
But intel security staff told investigators that a month earlier the security cameras had been spray painted. It was investigated as just sort of criminal mischief. But do investigators think that maybe this was a dry run? And I'm also curious, I don't know if you know this or not, Natalie, but was it the same security cameras or different ones? I imagine there's, you know, there are many, probably hundreds.
Natalie Morales
Well, you know, it seemed that Stephen Milner had been plotting this for a while, according to investigators. I mean, they do believe it was a test run. And the cameras that he spray painted were the cameras that he then spray painted. You know, a month later, in the act of killing Kenny Fandridge. They did notice it. They filed a suspicious activity report, as you said, but they couldn't pinpoint exactly who it was at the time.
Ann Marie Green
You see in the hour, the security footage, I mean, almost all of it is blacked out, except for the. Probably the most crucial camera. Right. There's one camera where he spray paints almost all of it. There's probably like one tenth at the top where you can actually see what's happening. And because of that little slip up, investigators were able to identify what they believe was the scene of the murder. Right. It's this maroon minivan.
Natalie Morales
Yeah. You know, that one tenth of a slip up, as you said, was huge for the investigators because with that they were able to see that maroon minivan just kind of making its way through the parking garage. Now, keep in mind as well, though, that they did have other security cameras all the way through. So as the minivan was making its way up, it was tracked throughout with other cameras that had not all been spray painted. That said, though, they were never really able to see the driver or to identify, you know, the killer in the garage. They needed to do all the police work to connect all those dots. So, you know, what was really fascinating about covering this case is, you see, this is a real police procedural. I mean, this shows you how well the police built their case. From the minute they had just that little sliver of video that they could see.
Ann Marie Green
When you, say, connect all of the other dots. I guess when you have. It seems like you have a little bit to work with, everything is incredibly important. And so in this video, where you can, like, see the person just a little bit, but he's almost completely covered, the only bit of skin that you can really see is right above his forehead. And so they identify this crease. I gotta tell ya, looking at that, that was something that I did not notice. I didn't even, like, consider it as a defining feature. I just thought maybe, like, the mask was pushing his head, his skin down. That would not have jumped out at me. But it became crucial.
Natalie Morales
Oh, it became huge. That forehead crease was such an identifying characteristic. Now, this was from the video from the security cameras a month before in that test run case, that they were able to see a little more of that mysterious person behind the mask. And that crinkle in the forehead, it turns out that's a genetic trait. I don't know if, you know, since viewing the hour, if you've started looking at people, but I know when I'm in airports or when I'm out and about, I start noticing that. And it's very rare that you see that forehead crinkle. So it was definitely something that was a huge break in the case when it came to trying to identify the suspect.
Ann Marie Green
I had no idea that was a genetic trait. Now you're, like, making me think about my forehead, but there's a wee bit of Botox up there, so it's not crinkling the way it used to be.
Natalie Morales
The other way.
Ann Marie Green
Yeah, exactly. All right, so this turns out to be sort of a critical clue, and the Hillsborough police immediately focus on Kenny Fendrich's wife, Tanya. It's not completely surprising. I mean, if you are a 48 Hours fan, you know, often the spouse is sort of the person that investigators focus on, but it's also about access. Knowing his schedule, knowing he is. There's only gonna be a handful of people who know that information. So inevitably, that's where investigators are gonna start. Now, I think maybe some people might see the video of Tanya and think that her demeanor's maybe a little cool, maybe suspicious. I. I didn't get that. I thought she seemed adequately, you know, concerned. But why did police ultimately rule her out?
Natalie Morales
As you said, people do look at the partner or the spouse, the person closest to the victim, Tanya, on the scene even before the responding officer arrived. That arouses some Suspicion. However, as Tanya tells that officer, she said, my husband has a stalker. And Tanya revealed that she had had a relationship with Steven Milner and they had had an affair. That it had ended years prior, but that Stephen Milner was still actively stalking Kenneth Vandridge and also keeping track of her, even though she had said many times, leave us alone. And she had also reported that to police.
Ann Marie Green
Let's talk about Stephen Milner. Here we have this veterinarian. He's a smart guy, he's popular. He seems sort of pretty normal, though. I mean, when they did have the affair, they were kind of eventually sort of blatant about it, Right? So that's a little odd for a guy who's, you know, you would think would be concerned about his professional reputation. But did you learn anything more about who he was and his personality?
Natalie Morales
We talked to a couple of his clients, as you saw in the hour, and they say that by all accounts, you know, he was very involved in the community, very well liked, was pretty much a well known figure in Oregon City where his vet practice was. They also knew Tanya because she worked with him and they had seen their interactions. So they talked about that as well.
Ann Marie Green
Something in the hour that I was really fascinated by. I don't know if it kind of hooked other viewers, but that police body cam video where he's being pulled over, right? And he tells the police officer that, you know, Tonya is in danger. Is he just sort of making this up or does he really believe this, that this is justifying his behavior when she wants nothing to do with him?
Natalie Morales
You know, when he was pulled over for following Kenny, Milner told police, look, I'm the only one who really gives a blank, as he said to the officer at the time. And I'm not allowed to give, you know, a blank. At that point, there had been issues between Tonya and Kenny foundridge of domestic abuse. Steven Milner really felt like he was the one that could save Tanya from what he felt could be a dangerous situation for her.
Ann Marie Green
Natalie, one of the videos that we see in the hour that kind of really touched me was it's of Kenny. He's sitting on the back deck, he's really distraught. He's crashed his car after an argument with his wife. And he just looks so sad and heartbroken. What more do we know about this marriage and the problems they had experienced?
Natalie Morales
Tonya and Kenny, they had struggled over the years. Alcohol typically came into play, according to Tanya, when there were these instances of domestic violence, it became something of a he said, she said, Tonya acknowledged their issues and as I said, she was, you know, very firm in saying this relationship with Stephen Milner happened years ago, it was in her past and that she and Kenny Fandrich were really trying to work through all those issues and they were stronger than ever as a couple.

Natalie Morales
Welcome back.
Ann Marie Green
So, Natalie, as you mentioned, investigators really didn't have a lot to go on linking Milner to Kenny's murder. So they really have to kind of dig in and find this evidence. They go to his house. So I want to ask you, what sort of things did they discover? And I definitely want to ask you what was up with that cardboard cutout in his house?
Natalie Morales
Yeah, that was a very odd clue. You know, Milner did have a male roommate who was living with him at the time of his arrest. But you know, investig when they saw that cardboard cutout, they assumed rightfully so that that was Stephen Milner's room because then they opened the drawers and they see he has this so called shrine to Tanya with all the love notes and letters that he had kept. He even acknowledged in those notes and letters, you know, I know you don't want me. There's no future here in this relationship that you want this to be over. But he couldn't get over it. So they felt that Stephen Milner seemed like the likely suspect based on on all of that. But that said, they still had to make their case and they had to have solid proof to connect that this Steven Milner who had this stalking history in past is the guy who was in the garage at the time when Kenny Fandridge was killed. And to prove that he was the one who actually committed the murder.
Ann Marie Green
That's the thing, you know, all that extra stuff that perhaps goes to motive, but you need some sort of solid evidence. So then what ultimately allowed investigators to build their case against Milner.
Natalie Morales
Well, it really came down to, you know, the good detective work as we talked about and following the maroon minivan trail. So Stephen Milner usually drove a white Toyota suv. And once they seized the car, investigators were able to analyze the data on the computer within the car, and they noticed that he had been going to an Oregon City Home Depot. He had been there, in fact, on the day of the murder. So once detectives Rigo and Winter went to that Home Depot, they asked security there if there had been any suspicious activity on the parking lots. Turns out the security did notice there had been a couple of cars that had been parking and had gone in and out of the parking lot a couple of times. Local law enforcement was called, and local law enforcement then saw these vehicles. They were able to get the VIN numbers off of them, these so called burner cars that said Milner was using. Detectives Rigo and Winter were able to then track down that maroon minivan to a scrapyard, which, as you saw in the hour, unfortunately their biggest clue, I mean, they believed the minivan was the murder scene just a week earlier had been crushed. So unfortunately, that big clue that they were hoping for in the minivan was then gone right before their very eyes.
Ann Marie Green
It still amazes me just how much how often we are all on camera. Right. But this is the first time that I've seen video as investigators sort of watched a key piece of evidence being destroyed. I'm sure they wanted to kind of like reach into the screen and just pluck that vehicle out.
Natalie Morales
Yeah. Unfortunately, they were a week too late, you know, to get that vehicle. Had they gotten there a week earlier, they probably could have had that and have gotten all the evidence they needed that said they were able to eventually get DNA. That was the concrete proof that they needed.
Ann Marie Green
Yeah. And we're going to talk a little bit more about that later. But before we do that, I want to talk to you about the two lead detectives. What was your take on this pair?
Natalie Morales
Oh, yes, Detective Stephanie Winter and Devin Riegel. I mean, these are like the dynamic duo of an investigation team. I really, we all were saying they really need their own TV show. I mean, Stephanie is about 6 foot 2 or 6 foot 3, former college basketball player, and this was actually her first homicide case that she worked on. So she was paired up with, with Devin Rigo, who had, you know, a real solid background in working homicides. And it was a real breakthrough case for both of them because, you know, you don't see a lot of murders in that area of Hillsborough Oregon. And here you have this mysterious, such a suspicious case. It really came down to them chasing all the leads and knowing where to go.
Ann Marie Green
And so finally, on January 13, 2025, Stephen Milner goes on trial for stalking and murdering Kenny Fandrich. But as we pointed out, a ton of forensic evidence is lost because that maroon van crushed. So the prosecution has to work around that. Was that sort of the. I guess that was the biggest hurdle.
Natalie Morales
So, of course, when the detectives see that key piece of evidence, that maroon minivan being crushed, they think, well, there goes our key evidence for trial. However, it really came down to the great police work in this case and being able to connect all the dots. And they had plenty of surveillance footage, not to mention past orders of protection, that proved that Steven Milner had been stalking Kenny Fanderich and Tanya and that there had been a history there. Yeah, they did have DNA as well. You know, Steven Milner's DNA was on Kenny Fandridge's hands. So that was crucial as well.
Ann Marie Green
So of course, Milner has an explanation for that. He did take the stand. There were no cameras in the courtroom, but there is audio. And so we're gonna play some of what he had to say to explain why his DNA was there. This was not included in the one hour broadcast. He is speaking with defense attorney Amanda Te. He both. He's under direct examination and here's what he had to say.
Defense Attorney Amanda Te
What happened next?
Stephen Milner
I jumped out towards him.
Defense Attorney Amanda Te
What happened next?
Stephen Milner
Then we basically fought for a little bit.
Defense Attorney Amanda Te
Okay, can you describe that fight for me?
Stephen Milner
There was pushing and shoving. I was kind of trying to push him back into his car and he was punching at me.
Defense Attorney Amanda Te
Did you punch Kenneth Vandridge?
Stephen Milner
Me? I don't know.
Defense Attorney Amanda Te
Did you kick him?
Stephen Milner
I didn't kick him.
Defense Attorney Amanda Te
Did you grab onto him?
Stephen Milner
Yes.
Defense Attorney Amanda Te
What happened next?
Stephen Milner
Eventually, I was able to kind of push him up against the car and then shove him into the car.
Defense Attorney Amanda Te
How much force were you using when you were pushing and shoving him, Mr. Milner?
Stephen Milner
As much as I could.
Natalie Morales
Why?
Stephen Milner
I was scared. We were fighting.
Defense Attorney Amanda Te
What were you scared of him?
Stephen Milner
That he was going to hurt me.
Natalie Morales
It's so interesting to hear. And first of all, even to just see him take the stand, you know, here Stephen Milner is not denying that he was there. He said I was there. Yes. I was the one who spray painted the cameras. But he claimed he did it all out of self defense. And he said when Milner confronted Kenny, he's like, kenny is the one who attacked me.
Ann Marie Green
He says that he's defending Tonya. I would think a self defense claim is pretty tough when, I mean, it's not like Tonya's there. He's seeking out Kenny at his place of work.
Natalie Morales
His whole, you know, self defense defense really didn't make sense, really. Stephen Milner said that his reasons for being there in the parking garage and for going after Kenny in that case was because he felt that Kenny Fandrich was a continued threat to Tanya because of the past abusive claims in their relationship. Now, the prosecutor, Mihaili Strieblo, said that that testimony did not line up at all with the physical evidence at the scene. It goes against everything that they were able to piece together. But, you know, I imagine that his defense attorney thought letting him take the stand and speak to his own defense and reasons for being there, perhaps if he could convince one jury member that, you know, he was the guy who was really just there trying to do a good deed, trying to protect Tanya. And in that, it was, you know, Kenny Fandridge who came after him. All he needed to do was to.
Ann Marie Green
Convince one juror clearly the jury didn't buy his self defense defense. Stephen Milner found guilty of murdering Kenny Vandrich and also found guilty of multiple stalking charges. He was sentenced to life in prison with the possibility of parole after 25 years. But I think what's really sort of tragic about this, this is a couple that did everything right. They did everything that they were supposed to do, and they still were not protected.
Natalie Morales
Yes. And that, in fact, is what is so tragic about the case, is that there's such a clear history of stalking here. And, you know, previously, Milner had been criminally charged back in August of 2022 when he had planted another tracking device on Kenny's car. Then Kenny filed that civil suit where he was seeking hundreds of thousands of dollars in damages for infliction of emotional distress. Prosecutors brought all of this up, and Tanya even raised it herself in her victim impact statement. She looked at Stephen Milner and she said all you had to do was stop. She said that she and her husband, Penny Vanderch, are doing everything they possibly could to try to alert authorities to Stephen Milner's stalking behavior. Prosecutors acknowledged the only other thing they possibly could have done because there had been multiple orders of protection already taken out, would be to track Stephen Milner himself. I mean, had authorities been tracking Stephen Milner, they would have seen there's about a 45 minute drive where he's going back and forth from Oregon City to Hillsborough and tracking Kenny Fandrich and following him as he went to Work.
Ann Marie Green
How is Tonya doing today?
Natalie Morales
Well, you know, Tonya obviously has experienced a lot of loss in her life. Nothing, no amount of money will make up for that. But Kenny's estate has a wrongful death suit against Stephen Milner. If any money is won, Tanya would stand to benefit. Kenny's estate is seeking damages of several millions of dollars. And reportedly Steven Milner sold his veterinary CL and apparently has an estimated net worth of several million dollars. But you can imagine she has to be shattered. She's a victim in this case. She was a stalking victim and then her husband was murdered. So she is a victim on so many sides of this case.
Ann Marie Green
Yeah, absolutely. You know, you always sort of try to look for the lessons in all of these stories. I think if there is a lesson and it's that stalking behavior is not normal. Right. It's not something to be dismissed and you should take it seriously.
Natalie Morales
Yeah. And certainly Tanya and Kenny Vandridge did. And still it was not enough in this case.
Ann Marie Green
No, absolutely not. Natalie, thank you very much.
