Welcome to 48 Hours Postmortem. I'm CBS News correspondent Ann Marie Green. And today we are talking about an episode that truly sent shivers down my spine, unmasking the Zombie Hunter. So joining me now are 48 Hours correspondent Peter Van Sant and producer Paula Rosa, who reported on and produced this episode. Welcome, gentlemen.
Amy Rosenthal
Hi. Thanks for having us.
Peter Van Sant
Hey, Anne Marie. Happy Halloween.
Ann Marie Green
It's a perfect episode for Halloween. It says it in the name, right? The Zombie Hunter. But before we get into the episode, let's play a clip from the show.
Amy Rosenthal
There are not many crimes that are like this one. You had women riding bicycles along the canal on a typical Phoenix evening, ambushed, stabbed multiple times.
Peter Van Sant
Brianna Whitney, the true crime reporter for the CBS affiliate KPHO in Phoenix, says the first victim was 21 year old Angela Brasso whose body was found in November 1992.
Amy Rosenthal
Police are looking at this scene and thinking what on earth happened and who did this?
Peter Van Sant
Ten months later, the body of 17 year old Melanie Burnas was found in one of the city's canals. Investigators found the same DNA at both scenes, says Detective Clark Schwarzkopf. I think there was over 600 persons of interest. After some 20 years, investigators zeroed in on 42 year old Brian Patrick Miller, a divorced father raising his teenage daughter. As Schwarzkopf soon learned, Miller had a unique alter ego.
Amy Rosenthal
Everybody in the Phoenix area knew Brian Patrick Miller as this character called the zombie hunter.
Peter Van Sant
Schwarzkopf secured Miller's DNA. Days later, the head of the forensic lab had some news.
Amy Rosenthal
She leans down to me.
Peter Van Sant
She goes, it's him. I go, what? She goes, brian Miller, it's him.
Ann Marie Green
Peter, what stood out to you about this case that made you want to do it?
Peter Van Sant
Well, first the zombie killer. I looked it up. You know, a zombie is relentlessly aggressive. Reanimated human corpse, right? So you have that component which I found fascinating. And then for me personally, I lived in Phoenix for four years. I worked in local news there, this was just before these canal murders. I left, but my home was about three miles from where these murders occurred. I used to jog along the Arizona, Arizona canal. And back then it was a hub of people on the canal. When we went and shot this, it's amazing. There's no one on these anymore. That's how lifestyles were changed in this. I also have this never ending curiosity about why do people kill? It's one of the reasons why I do this job. It's one of the reasons why I love to try to talk to the accused to get inside their head. And look at the head of this man. He was in this costume, like a comic book character. Instead of going off and hiding under a rock somewhere, this alleged killer was out in the public posing with photographs with police officers, for goodness sakes, going to these sci fi conventions. And he sounds like such a psychologically complicated person. Where you hear these stories of him being a sweet, loving father to his daughter. Friends who thought he was engaging, they never sensed danger with this man. Sometimes he was a bit odd, but he had this Jekyll and Hyde personality.
Amy Rosenthal
Like Peter said, that's what's fascinating about murder. It's these two sides. And in this case, you know, Brian's lawyers said he had two sides, that he had a trauma side and he had a normal side. He was not the zombie hunter when he committed the murders of Angela and Melanie back in the early 90s. And they were vicious. I mean, these aren't. These women are women who went out for nighttime bike rides along this busy canal path in Phoenix in good weather. And, you know, Angela was the first victim and her head was cut off. She was beheaded, and the head was not found until 10 days later. So. And she was eviscerated. I mean, these are horrible, horrible crimes. And Melanie, you know, she was found stabbed to death. So because of the nature of the crimes, the cops always felt that it had to be a surgeon who did them or someone with special forces training. And there's a military base in Phoenix and they just didn't believe it could be Brian Patrick Miller, who was around 21 or 22 years old at the time of these murders. And when you meet him, he's like a marshmallow. People describe him as a marshmallow. He couldn't do one pushup. His friend said he doesn't seem like the kind of guy who could commit these horrible crimes.
Ann Marie Green
Can we talk about how Melanie was discovered?
Peter Van Sant
This was a story that Paul managed to find a woman by the name of Charlotte Pottle. And this was literally as we were finishing up our hour, we'd already written the show and most of our editing was done, But Charlotte Pottle was worth the effort. Back in 1993, she was riding along the canal to. When she drove through a dark puddle. She instantly felt like, something's not quite right here. That was really bizarre. She rode for just a few minutes and decided to double back and realize that it was a pool of blood. And she got off of her bicycle, and Charlotte noticed that there were drag marks in the dirt. The first drag marks went off away from the canal to a single tree. She said the body had been moved around that little tree, and there was a small pool of blood there. The body is then dragged back across the path to the edge of the canal where it apparently was thrown in. And so Charlotte Pottle, she later called police, and she called them on an emergency tip line that was not supposed to reveal the identity of the caller. And she described her experience and told cops, you should go out there and check it out for yourself. Well, sometime later, she gets an unexpected call from a homicide detective. And the homicide detective said in a very demanding way, where are you right now? And she goes, well, I'm at my house. Stay put. I'm on my way over to talk to you. Do not move. So she waits at home, she said. The detective shows up, and he immediately accuses her, Charlotte Pottle, of being the killer. And why? Because her footprints were on both sides now of these drag marks out at the canal. And he says, I know you did this. She said, I had nothing. I just discovered it. She thought she was going to be arrested. He leaves, and she's convinced any moment she's going to be arrested as the canal killer. She said they never call again, and they never showed up. And she lived with this fear for months. But Charlotte did the right thing.
Ann Marie Green
Yeah.
Peter Van Sant
And luckily, she wasn't charged.
Ann Marie Green
That's an incredible story, Peter. You know, you talked about the surgical precision almost. Her head was pretty well preserved. What do police believe happened, Peter?
Amy Rosenthal
You can talk about that.
Peter Van Sant
So when this head is discovered, according to Detective Clark Schwarzkopf, he believed that the killer had kept the head in a refrigerator. It was a head that he may have considered a trophy. And in the plan, this handwritten document that Bryan Miller had produced that his mother had discovered and turned over to authorities, one of the items on his list was to decapitate a victim and to keep the head. And Detective Clark Schwarzkopf believes that's exactly what happened here and that he wanted it discovered because Detective Schwarzkopf believes he wanted to get some shock value from these murders.
Ann Marie Green
So Paul, how did you get to know him?
Amy Rosenthal
Well, I started writing him emails and, you know, I couldn't reach him during the trial because his lawyers are in the way and they obviously won't let him speak to a journalist during the trial. But after the trial I took a chance and there. Even when he's on death row, but even on death row, inmates have access to email, which a lot of people out there may not know. And I didn't know if he'd write back or not. And the first time he wrote back, he said he didn't like CBS News. I said, well, I've been doing this a long time. I have. I've worked at the show for 30 years, so I've been doing this a long time. And you can Google me and you can check me out and you know, I think I'm an upstanding journalist and I'm not going to lie to you or anything. And he started writing. So we went back and forth and I started asking him simple questions at first, like what do you miss? You know, do you miss being the zombie hunter? And he said, you asked me simple questions, so I'm going to answer you and I. And we just kept going on and on until eventually he started talking about the case more and more. And he said he didn't commit these murders. And I said, well, Brian, that leads to the big question. How is it that your DNA was found on both women? And he said, that's the million dollar question. If I knew, I wouldn't be sitting here, would I?
Ann Marie Green
Wow. So let's talk about that because then there's these two murders, There's a stabbing earlier, but two murders and then nothing.
Amy Rosenthal
Brian seemed to have cleaned up a little bit in the late 90s. He married Amy. He got married and she, by the way, described him as the perfect gentleman. On their first date, which was at an amusement park by the side of the canal where they found one body and Angela's head. So he married her in Phoenix and then they moved to Washington state where his mother lived. They had a child. And there's some video of them from the time on a whale watching trip. And they look like any young family, you know. And so we don't think Bryan really changed his ways. He stabbed a woman up there. He said it was self defense. And that case went to trial and Brian Patrick Miller was acquitted. The jury believed him over the woman wow.
Ann Marie Green
So the murders of Angela Brasso and Melanie Bernis went unsolved for decades. And like so many of these cases that are only now getting solved, the real smoking gun in this one is the DNA evidence that pinned Brian to these murders. But police almost didn't get it. Let's take a listen to investigator Clark Schwarzkopf describing just how they got the crucial evidence. At Achilles, of all places, the Cold.
Peter Van Sant
Case unit was behind the scenes ready to bag anything that had Miller's DNA on it, such as utensils or a glass. They set a table for me and.
Amy Rosenthal
Mr. Miller away from everybody else in a part of the restaurant where nobody else is at.
Peter Van Sant
Miller arrived with with a surprise guest, his 15 year old daughter, Sarah. Miller was a divorced single dad.
Amy Rosenthal
He was very gentle and caring about his daughter.
Peter Van Sant
He often brought his daughter where he would be going. The trio sat down and ordered hamburgers. When the food arrived, he swallows his.
Amy Rosenthal
Hamburger in like five bites, won't take.
Peter Van Sant
A drink of his water.
Amy Rosenthal
And I'm sitting there going, are you sure you want something else to drink?
Peter Van Sant
Have you just got water?
Amy Rosenthal
No, no, I'm good, I'm good, I'm good.
Ann Marie Green
So good news is he's really hungry. Bad news is he's not thirsty.
Peter Van Sant
That's right. And it went on and on. And by the way, the other people that were in that section of the restaurant were undercover agents.
Ann Marie Green
I wondered about that, watching.
Peter Van Sant
And the manager of the Chili's a great citizen. This woman said, I'll be the waitress. So she played the waitress in this scenario. And finally, finally he takes a sip from his water glass and. And that's when Schwarzkopf knew this was mission accomplished. As we said in the story that he got the DNA sample. So Clark Schwarzkopf, you know, was a seasoned detective, right? This goes back to the duality of Brian Miller. He had approached him at his place of work. He posed as a security guy. He said, would you like to work for us keeping an eye on the back part of the factory here? Cause there's been some theft. I'll pay you $20 an hour. Well, anyway, he got to talking with him back and forth, right? Got a sense of the man. Then they have this lunch together, brings in his daughter. He seemed like a loving father. He seemed normal. And despite what Schwarzkopf knew of his past, he felt as though this guy, this nerdy, soft spoken man, he couldn't possibly be the Canal Killer. And so he gets the DNA sample and they send it off. But in his mind, he goes, it's going to come back. It's not going to be a match. Cause there's no way, based on my experience, that this guy is a killer. He's just too nice a guy. It's kind of extraordinary, but it shows you the power of his personality.
Ann Marie Green
Wow. So they get all the evidence they need. They've got this DNA match. And so they get a search warrant for his house. And it's like this guy has never thrown anything out. He's basically a hoarder. Let's listen to a clip from the show.
Amy Rosenthal
I can remember, like it was yesterday walking up to the front door and everybody going, you can't get in that way.
Peter Van Sant
It's full of crap. Brian Miller's house was like. It came from the show Hoarders.
Amy Rosenthal
There was a little path where you could get to a bathroom in the.
Peter Van Sant
Kitchen and where the TV was.
Amy Rosenthal
And that's it. Everything else is just stacked to the roof with garbage.
Peter Van Sant
Did you look around and go, this is madness?
Amy Rosenthal
Not only madness. I go, this is a nightmare? Yeah, this was a nightmare. They have to look through this stuff. You know, it's a house filled, completely filled to the ceiling with stuff. And they are looking for the women's bikes from back then. He have. He had a lot of bikes when they arrested him, but none were Melanie or Angela's bikes. They're looking for a murder weapon, a knife. They found a lot of knives, but not the murder weapon. But they have. But they did find a lot of pornography, some of it violent. Yeah. So that was. It's just a nightmare.
Ann Marie Green
So still a lot more to talk about when we get back. I want to talk about Brian's ex wife and his daughter, Brian's juvenile record and of course, course the trial. What will the zombie hunter with his larger than life Persona, what will he use as his defense strategy? We're going to get into that after the break.

Ann Marie Green
Welcome back. When I look at this case, I cannot help but to think about the people in Brian's life. Can you tell me anything more about the ex wife? I was shocked that a man like this had custody of his teenage daughter. How did that happen?
Amy Rosenthal
Well, at the time, I would say that his ex wife, Amy, was. Had lived a troubled life. As far as I've learned, she did not come to the final custody hearing, and the judge awarded Brian custody of his daughter. Brian always treated his daughter Sarah with respect and kindness. From what we learned, she had a fairly normal upbringing, although she did live with him in the house, which was described as a hoarder house. So, you know, that comes with its own psychological underpinnings. But other than that, living in a hoarder house, they seem to have a really good, loving relationship in a way.
Ann Marie Green
That brings me back to the ex wife too, because, you know, he was a good husband until he wasn't, according to her. She must have told the court about her experience. I mean, she was terrified of him.
Amy Rosenthal
One thing about Amy is that, and she testified to this, is that she felt intense duty as a wife to do whatever her husband wanted her to do. She said that at trial, you know, it was her duty to do what he wanted. Coupled with that is that she was really afraid of him. And it's heartbreaking. But at one point in the trial, the prosecutor says, why didn't you object to all this stuff in the bedroom? And she said, well, I wanted to do it because it's my duty as a wife. And I wanted to be sure that he loved me enough not to kill me.
Ann Marie Green
Jeez, that's heavy and heartbreaking.
Amy Rosenthal
It is. So that sort of sums up where she's coming from. You gotta feel great sympathy for her.
Ann Marie Green
Completely. I wanna ask about the juvenile record too. How much access do investigators have to a juvenile record typically?
Peter Van Sant
Well, these juvenile records usually are kept under seal, but these investigators were able to get that information about him. He had stabbed a woman in the back and been arrested for that and serve time in juvenile detention. So Celeste Bentley worked at a mall, and she took public transportation to get to her job. She's on this bus and she notices this young man behind her a few rows. She turned, she noticed he was looking at her. And when she got off the bus, she noticed that the young man got off as well. And this was very early in the morning, and she's walking across an empty parking lot headed toward the Department store where she works. And then all of a sudden, he sprints by, and she feels this punch, she thought, on her back, and it hurt. And she called out to him, why'd you do that? And she put her hand back and discovered it was blood. Then she runs to the department store. There was a single door. It was locked. She's pounding on it. Luckily, one of her colleagues is there, lets her inside, and they call the police.
Amy Rosenthal
But she said the police told her that if he had turned the knife just a little bit one way, it would have gone right through. And it hit ra Also.
Ann Marie Green
It could have been a murder.
Amy Rosenthal
Yeah, it could have been a murder. So the police found him, found Brian dressed in different clothing. So he had planned this. He changed his clothes. They brought him over to that. Brought him over to Celeste, and she identified him. And he eventually pled, and he admitted to the cops that he had stabbed her. You know, there's various stories about why he did. One was he said he just wanted to see what it felt like, and it sent chills down his spine. There were other reports later that he stabbed Celeste because she reminded him of his mother.
Peter Van Sant
The thing about Celeste Bentley, you know, I interviewed her. This is a woman that has lived with this trauma, obviously, for her entire life. It so impacted her life. She was afraid to be in crowds. She's always had her head on a swivel, always looking around her and still does.
Ann Marie Green
Yeah. Part of his defense was to talk about his childhood. So looking at his childhood, the abuse that he alleges, what proof was provided?
Peter Van Sant
Well, it began the fact that when he was 16 years old and he committed that attack, it turned out that he had told social workers back during the juvenile detention that he had. He told these details of his mother's abuse. And so the fact that he had told with such detail and very specific about the kinds of things. Exposing him to pornography, exposing him to violent movies, beating him. He tells this story of being beaten with a belt, experiencing violence, psychological trauma, physical trauma, and then exposed to these horrible images is something that he kept with the rest of his life.
Ann Marie Green
So that becomes kind of part of the defense. Right? Let's just listen.
Peter Van Sant
Psychologist Bethany Brand testified that Miller developed a condition known as. As dissociative amnesia and inability to remember some traumatic events. Morgan Lowe summed up the defense argument. There were two Bryans. There's the one you see over there at the defense table, who's a fairly normal person who has friends, who had a job, who was a dad, who was a husband, and then there's the killer. There's bad Brian. And Miller claimed his attorneys and had no memory none of the two murders he was charged with. Keep in mind, the prosecutors disagreed. They believe that he seemed to have memory of other traumatic events that he could recall and say, I didn't do that. Events in which people were stabbed but survived somehow. He still remembered that. So, I mean, does the skeptical part of me still wonder about that? Of course. It seemed. It seemed just too convenient.
Ann Marie Green
Brian decided not to take the stand during the trial, but he gave a statement. Let's just hear a little what he had to say.
Peter Van Sant
I am not looking for sympathy today.
Amy Rosenthal
This time is for the family and.
Peter Van Sant
The friends of the victims. I cannot imagine what pain they have.
Amy Rosenthal
Endured from these years.
Peter Van Sant
I know I am different.
Amy Rosenthal
I thought I had to do with.
Peter Van Sant
What my mother did to me. These kinds of cases, the families involved. This man created, you know, torturous lives for so many people, caused such profound harm.
Ann Marie Green
Yeah.
Peter Van Sant
The horrors that he did.
Ann Marie Green
Yeah.
Peter Van Sant
To lose your child and to lose it under these circumstances where there was mutilation and things a family never gets over that can't get past it.
Ann Marie Green
Another fascinating case. Another just incredibly baffling character. Paul, Peter, thank you so much.
Peter Van Sant
Thank you, Amy.
Amy Rosenthal
You're welcome. Thank you.
