This episode covers the murder case of Deborah Atrops, featuring guests Ann Marie Green and Natalie Morales. The discussion includes the timeline of events leading to her death, the investigation, and the eventual arrest of her estranged husband, Bob Atrops.

Deborah Atrops was found strangled in the trunk of her car in Oregon in 1988. Her husband, Bob, reported her missing after she failed to pick up their daughter. The police investigation raised suspicions about Bob's behavior during the 911 call and his lack of evidence for phone calls he claimed to have made.

The episode highlights the complexities of the case, including the relationship between Deborah and Bob, and the involvement of another man, John Pearson, who was dating Deborah at the time. Despite initial suspicions, the investigation went cold for decades.

New DNA evidence and a re-examination of the case led to Bob's arrest in March 2023. The episode discusses the trial, the emotional impact on their daughter, Rihanna, and the differing perspectives on Bob's guilt.

Ultimately, Bob Atrops was convicted of murder, receiving a life sentence. The episode concludes with reflections on the tragic consequences of the case for Deborah's family.

TLDR

Deborah Atrops' murder case, unsolved for decades, leads to her estranged husband Bob's arrest and conviction after new evidence emerges.

00:00:06
Welcome back to Postmortem. I'm your host Ann Marie Green and joining [music] me today is 48 hours correspondent
00:00:11
Natalie Morales. We are going to discuss the case of Deborah Atrops. Now, back in
00:00:17
1988, the young mother was found strangled to death in the trunk of her car in Oregon. For decades, her murder
00:00:24
remained unsolved and it would take 37 years to bring her killer to justice. Joining me now is Natalie.
00:00:33
>> Hi, Anorie. Good to be with you. Hey, Natalie. It's always good to be with you. Um, this is one of those hours that
00:00:38
I just kind of went back and forth. I was so convinced that they, you know, that they had the right suspect, then
00:00:43
they then they had the wrong suspect. I just >> I was ping ponging. >> I think it even for me as I was
00:00:49
reporting on this case, it was I was very conflicted. even our producers, we were conflicted. But this case was cold
00:00:55
for over 30 years. So really, it was all about figuring out what new evidence could be presented at trial. Uh if you
00:01:04
haven't listened to the 48 hours episode yet, you can find the full audio version
00:01:08
just below this episode in your podcast feed. Go take a listen and then come on back for the conversation. Uh Deborah or
00:01:15
Debbie Atrops was last seen alive on Tuesday, November 29th, 1988. Her husband, Bob Atrops, first reported
00:01:24
her missing to Oregon police when he said she never arrived to pick up their baby daughter, Rihanna, uh from Bob's
00:01:31
house. Uh so I should point out that Bob and her they are estranged, right? So they have been separated. Um, but Bob
00:01:39
calls the police like pretty quickly after he felt that she should have been picking up their daughter. He tells them
00:01:46
that Debbie was running about three hours late from a hairdressing appointment. So, to me, this was like
00:01:51
the first indication, like very early on, I thought, "Oh, yeah, he's the one." Because I just, it just seemed like 3
00:01:58
hours was too soon to be calling the police. And at least in the portion of the 911 call that we heard, it's not
00:02:04
like he said, "I've been everywhere. I went to her apartment. And I I called the hairdresser. Like it just something
00:02:10
about the 911 call seemed off. Yeah. All valid points, Amarie, you know, and actually really wasn't even 3 hours
00:02:17
because her appointment ended at 7:15. She was expected back at Bob Atrop's house around 7:30, 8:00. So he's calling
00:02:26
really less than 2 hours after that time frame. and police uh well detective Okonnell I should say who was one of the
00:02:34
uh initial people who was on this case he he said that felt strange to him too. It's sort of that Shakespearean you know
00:02:43
that quote thou doth protest too much and prosecutors believe those phone calls were almost to try to um make
00:02:51
police believe that uh he wasn't involved. Interesting. Now, he does say back in 1988, he tells police that he
00:02:59
called other people. He says he called the babysitter, called uh Debbie's boss and her parents from his home phone, but
00:03:07
the problem with that is that it couldn't be confirmed because there was no record of these phone calls on his
00:03:13
home phone and they were long distance. So, they they should have been a record someplace.
00:03:19
>> Yeah. And I should remind people this is 1988. This is Oregon. So calling from
00:03:24
one town to the other town, that could sometimes be a long-distance call. Bob lived about 30 miles from where Debbie's
00:03:31
parents lived. So all these phone calls should have been recorded somewhere as long-distance calls on a phone bill. So
00:03:38
it became a big part of the mystery was where are these calls? Now, we know that
00:03:44
he did place these calls because Debbie's parents did confirm and her stepfather confirmed that they received
00:03:50
the calls. the babysitter confirmed that she received a call. So the question is
00:03:54
where did he make the calls from? Investigators believe that Bob maybe had, you know, committed the murder and
00:04:02
was dis trying to get rid of the car and dispose of Debbie's body and that's when
00:04:08
he made those calls as he was out and about. >> Were they looking for I don't know
00:04:12
public telephone like telephone booth? >> They went around and looked at all the
00:04:16
public pay phones that they could find. They tried to get phone records off the payoneses. But that said, you can't go
00:04:24
around and trace and track every pay phone in the neighborhood. I should also say the one phone call that Bob didn't
00:04:32
make, which was very telling to investigators, was he didn't try to call Debbie's house. Now remember, they're
00:04:38
estranged. So she has an apartment in Salem, Oregon, and he never even calls the apartment and never goes to the
00:04:48
apartment either to try to see if she ended up deciding to go straight home. So that was very telling to
00:04:55
investigators. Bob Atrops explained that away as saying, "Well, I had already called Debbie's parents and they said
00:05:05
she had not gone home." Okay, so you know, sadly Debbie is not a missing person for very long. Less than two days
00:05:13
later, police discovered her uh abandoned car near a construction site and then inside they discover Debbie's
00:05:20
body face down in the trunk of her car. She had been strangled, but no signs of sexual assault.
00:05:27
So, at this point, I would think the only person to look at would be Bob. Did Did police zero in on him as a suspect
00:05:35
right away? You know, obviously, as we have reported all too often, the partner or the spouse or in this case, the
00:05:42
aranged spouse is definitely the first person they consider and they look at. Um, and they did search outside Bob's
00:05:49
house. They in fact u checked his driveway, which was a gravel and muddy sort of driveway. They took pictures of
00:05:55
that driveway. They even took a mud sample of the driveway and the lawn as well because on the top of the car, the
00:06:03
hood of the car, it appeared there had been some mud evidence that had been wiped away. On Debbie Atrop's body, on
00:06:10
her coat, they found mud on her shoes. They were muddied as well. So, they were trying to match the sample of mud
00:06:17
specifically and also trying to verify the tire tracks. Now, they never could verify her tire tracks on his driveway.
00:06:26
A lot of people, a lot of friends were visiting in the time that he reported Debbie missing. Obviously, a lot of
00:06:31
people very concerned about Debbie. So, police were never able to definitively say whether or not Debbie had come back
00:06:39
to the house uh based on tire tracks. >> So, then let's talk about their relationship. We know they're strange,
00:06:46
but I mean, do we know anything about the nature of the relationship at the time that she goes missing?
00:06:51
>> She was living, as I said, in this whole other apartment. She was also involved
00:06:55
in an entirely new relationship with a man named John Pearson. Friends said that Debbie was very afraid of Bob
00:07:03
finding out that she was already dating this guy. John Pearson was somebody she worked with and Bob apparently knew her
00:07:11
boss. They were good friends, so it wouldn't be, you know, too crazy for him to find out. But um Debbie's friend uh
00:07:20
Tammy Nelson also said back in 1988 that Bob Adops had a temper that he had actually uh had choked her according to
00:07:27
Debbie shortly before she moved out. And you know she had even told friends if something happens to me Bob did it. Yeah
00:07:36
those are definitely some famous last words. Um, but she is dating this other person, John Pearson, which is what
00:07:44
started me when I was watching the hour, moving away from Bob as a suspect. Um, he was interviewed by police. He told
00:07:51
police that he had been uh with his aranged wife and children on the night of Debbie's disappearance. Um, but he
00:08:00
also gave a detailed description, a really detailed description of Debbie's car and what was in the trunk. And it
00:08:07
just I know I can't even tell you really what's in my trunk right now. So it just
00:08:13
seems like an odd amount of detail to remember, you know. >> Yeah. I mean, it was a very detailed
00:08:19
description of what was in the trunk. Um, you know, John told police even how could a body even fit in the trunk,
00:08:27
which kind of strange words to say. He thought the trunk was too small. And so I asked the prosecutors, Allison Brown
00:08:34
and Chris Lumen, about that. Take a listen. >> John Pearson told police back then that
00:08:39
there was a Burger King [clears throat] bag as well as a box with cranberries and a child's car seat. Seems like a lot
00:08:46
of details about the car. I mean, that's not details that I don't think my husband knows what's in my car. That
00:08:52
seems like somebody who's very intimately involved with knowing what's in the contents of that vehicle.
00:08:56
>> Well, and I think >> uh we knew that Mr. Pearson had been with her. I mean, he admitted that he'd
00:09:02
been with her. Um, they had been dating and and was in that car frequently. Um, and then I think his his surprise that
00:09:09
how could the body fit in the trunk? I mean, uh, as we we mentioned, it was delicately placed in there. It's not a
00:09:16
it is not a large trunk and and that had to have taken some effort to sort of get
00:09:22
Debbie's body in the trunk. >> Does it seem like an odd commentary, though? Yeah, I mean I think they asked
00:09:27
him specific questions about the car and its condition and they were seeing each
00:09:31
other every day. I mean not only were they in a romantic relationship, they both worked at Wellins, so they would
00:09:36
often have lunch together. Um I think they had lunch together the day prior and so um you know he would see he would
00:09:42
see her often. >> Detective Okonnell who interviewed Pearson back in 1988 said that Pearson
00:09:48
was actually very forthcoming when when he was questioned. He agreed to many interviews, in fact, and that he even
00:09:55
took a polygraph. He passed the polygraph. So, Detective Okonnell felt like it wasn't like Pearson was trying
00:10:01
to hide anything at the time. >> Okay. And at the time, there's still some question marks about Bob, but
00:10:06
there's really no evidence connecting Bob or anyone else to Debbie's murder. So, the case goes cold, right?
00:10:13
Meanwhile, Bob continues to live life. He raises the couple's daughter, Rihanna. Um, she's in her late 30s right
00:10:20
now. you spoke to her. She describes him as a great dad. He's doing and attentive
00:10:26
and he's a fantastic grandfather to her three children. Um she does not believe that he had
00:10:33
anything to do with her mother's murder. Yeah. You know, it was it was heartbreaking speaking with her, of
00:10:38
course, because here's a a a young woman who never even knew her mother. She was
00:10:43
8 months old when her mother died. So, she feels that loss still very greatly in her life. And then now she said she
00:10:51
feels like she's lost the only person that she [music] feels she could count on her entire life and that was her
00:10:58
father who raised her. And she does feel like he is 100% innocent. Well, decades after Debbie's murder,
00:11:08
detectives and prosecutors with the cold case unit start looking at Bob Atrops again. [music]
00:11:14
And we have seen this before, Natalie. Sometimes it's the same evidence but with fresh eyes and they see things
00:11:21
completely different. Fresh eyes and new technology. I mean, keep in mind from 1988 now to, you know, 30 plus years
00:11:29
later how much DNA uh has changed things when it comes to cold cases. There was,
00:11:35
you know, Debbie's coat with that. They take a look at the DNA evidence and they
00:11:41
were able to exclude John Pearson and Jeff Freeberg who was a former ex but he was no longer romantically involved with
00:11:49
Debbie. However, they couldn't definitively exclude Bob Atrops. Now, the defense points out the amount of DNA
00:11:58
that they had was the equivalent of perhaps six skin cells, which is a minute amount. So, they said this is
00:12:06
like the weakest bit of evidence that you could possibly even have. Um, and they said as well, according to the
00:12:13
defense, the fact that they shared custody of Rihanna, it's expected that there would be some sort of
00:12:19
crosscontamination with DNA. And remember those soil samples that I talked about from the driveway and the
00:12:25
evidence that was on the car. So, the FBI analyzed the mud that was found on the tire of the car and also they looked
00:12:33
at the soil that was taken from Bob Atrops's lawn and they said that the mud on the tire was indistinguishable from
00:12:41
the mud from Bob's lawn in color, composition, and texture. So, that would be a real compelling piece of evidence.
00:12:47
In fact, there became this whole part of the trial that was all about the soil evidence. They had soil experts testify.
00:12:55
The defense said though when it comes down to it, it's soil that is so common place in the Wamut Valley that they're
00:13:03
like, "How could you definitively say that it's Bob at Trops' lawn?" Yeah. And so then detectives do something really
00:13:12
interesting like one of the holes in Bob's story back then is about these phone calls, right? How come there's no
00:13:18
record of these phone calls you say you made? So they rein him in 2022 and they ask him again about that night and the
00:13:25
phone calls he made, but this time he's got a different story that he didn't tell them the first time around.
00:13:31
>> Right. So So Bob is a salesman and so at the time he was. So his now he's telling
00:13:38
detectives, you know, all these years later, well, those phone calls weren't there because I used an MCI calling card
00:13:46
to make those calls. And the prosecutors are like, "No, no, no. That just doesn't
00:13:53
add up." Because when you make a call using these calling cards, then you have to punch in this code, this 16digit
00:13:58
code. It just didn't sound like the act of a frantic husband who's calling 911, but then also is he like sitting there
00:14:05
punching in the code to to, you know, just try to make these calls. It It just didn't add up to the prosecutors.
00:14:12
>> Yeah, that it makes a lot of sense. >> The defense, however, presented somebody
00:14:16
at the trial who said that the equipment could have been faulty at the time and it didn't necessarily record all the
00:14:22
calls that came through in the area. >> Okay. Um, but ultimately detectives do arrest him, right? He's arrested in
00:14:30
March of 2023 um for Debbie's murder. What about the other suspects though? Because I got to
00:14:37
tell you, when I was watching Yes. Initially the phone call was it was troubled me. But later on I thought,
00:14:45
well, what about John? I mean, there are other people. >> Yeah. Yeah. You know, Jeff Freeberg, I
00:14:51
think Detective Okonnell, they pretty much figured he was not a person of interest. Also, back from the lab, the
00:14:58
DNA evidence, the mixture uh from the coat from from Debbie Atrops's coat excluded John Pearson. However, what was
00:15:06
interesting about John Pearson, he had apparently moved to Arizona and was living in a trailer when 5 days before
00:15:14
Bob's trial, two police officers show up outside the trailer, they are out there.
00:15:22
They're saying, "We're here. We want to talk to you." John Pearson looks out the
00:15:26
window, sees them, and then kills himself. See, for me, that was I I thought, "Wait a minute. Why would you
00:15:32
do that?" Right? What are you trying to hide? Right. According to the prosecution, he had a DUI apparently
00:15:38
that he was um wanted in court for. Take a listen. >> Um he had an open criminal case. I
00:15:46
believe he he thought they were there to arrest him for this misdemeanor warrant
00:15:50
and and took his life. >> The prosecution also noted his family said he wanted to testify against Bob at
00:15:56
Trops. We don't really know what was going on in his mind at the time, but investigators and the prosecutors truly
00:16:02
believe there is no evidence that points to John Pearson in this case. That all the evidence squarely pointed at Bob at
00:16:10
Trops. >> So when Bob is arrested though, his daughter Rihanna is completely blindsided.
00:16:16
>> Yeah. Rihanna, you know, she's just been so upset at the entire process. She said, you know, she got a call at 5:00
00:16:22
a.m. that morning telling her that her father, Bob Atrops, had been arrested. Beyond that, she says that at trial,
00:16:30
they kept calling her Rihanna instead of Rihanna, which is how her name is pronounced. She was never given a
00:16:36
victim's advocate, whereas Debbie's brother and stepfather had a victim's advocate at their side. Um, here's a
00:16:42
little bit more of what she had to say. The prosecution stood there in trial and
00:16:48
made me out to be the most important thing in my mom's life. I'm her baby, her daughter,
00:16:58
but the prosecution never treated me as such. >> Um, so I asked the prosecutors about
00:17:05
that. I I asked the point blank. I mean, how did they feel about how they treated
00:17:09
her? And here's what they had to say. And and during the trial, Rihanna told us that she was not contacted by a
00:17:15
victim's advocate from your office. Um even though here it is, it's her mother who was murdered. Um
00:17:22
>> why not? >> We have the indication that she didn't want to have any contact with us. Um
00:17:28
that she was on the defendant's side um and that wasn't interested in in being part of our case or having contact with
00:17:35
the prosecution. That was my understanding. She also said that she was not informed
00:17:40
ahead of time when the autopsy photos were going to be shown in court on the day during the trial. Um, meanwhile, you
00:17:49
know, Debbie's brother had been informed ahead of time and he left the courtroom
00:17:53
because he knew it would be too hard to see. What do you say to that? >> Yeah, I mean, I I can't imagine how that
00:18:00
would feel. Um, again, her not having contact with our office, we it's difficult for us to sort of alert
00:18:07
everybody in the courtroom, here's what we're about to do. And certainly that was not intentional.
00:18:12
>> Yeah. You know, sometimes it's the nature of the system that, you know, if you're not a defendant and you're not a
00:18:19
witness, then it's like you don't have a role, >> right? And that's that's how she feels.
00:18:25
she feels that she got lost in the process, but also that they excluded her because they knew she was on her
00:18:34
father's side and she was going to defend him all the way. So then what sort of evidence did the prosecution
00:18:41
have? What sort of evidence did they present that connected Bob to this crime? Perhaps the most compelling part
00:18:48
of evidence, according to the prosecution, was the alleged pattern of domestic abuse in their relationship.
00:18:55
Debbie's mother had told police at the time of the murder that Bob at Chrops was verbally, physically abusive and
00:19:01
very controlling, that she immediately suspected that Bob was the killer. And as we mentioned earlier, her friend
00:19:07
Tammy Nelson testified that Debbie told Tammy that he had choked her before. I mean, that right there is is is
00:19:16
evidence. Um Tammy also told the defense team that Debbie told her that um she was scared of Bob, especially when they
00:19:25
had to hand off Rihanna. That's when those moments, those confrontations could happen. And that's exactly what
00:19:30
prosecutors believe is what happened. When Debbie went to the house that night, he had found out about her
00:19:38
relationship with John Pearson. And that set it up for that night for this confrontation and and and for him to
00:19:46
then in a fit of rage um strangle Debbie Atrops. >> Um the defense argued, however, that
00:19:54
Debbiey's stories were unreliable. We hear this version of Bob, but at trial, there were a lot of people that
00:20:02
were there supporting him, not just his daughter. Yes, he had a lot of support, including
00:20:08
his fourth wife uh was there. He's, you know, been married since 2011. He did have two other marriages and divorces
00:20:16
after Debbie's murder. Um so, you know, but as Chris Luman, the uh assistant prosecutor, said that he can be charming
00:20:25
and he he knows how to get his way and how to have people, you know, believe him.
00:20:31
So ultimately though, the jury does find him guilty of murdering Debbie Atrops. The defense was rather emotional and you
00:20:40
don't see that very often. Yeah. Yeah. In fact, defense attorney April Yates uh was very emotional. She said that Bob at
00:20:48
Trops is is in an innocent person who has been convicted. Of course, Rihanna is now a victim twice over. That's the
00:20:57
way she feels. She mentioned that to you. uh she never got to know her mother and now she's also lost her father and
00:21:02
she gave a really powerful statement at his sentencing. I'm curious about the reaction um when she read that
00:21:09
statement. It was it was a moment that I felt was very very telling. You know, Rihanna is there. She's pleading with
00:21:15
the judge to you know spare her father to to be more lenient in the sentencing telling the judge that she and her three
00:21:23
kids they need their father and grandfather. Um Bob at that point he hardly ever looks in her direction and
00:21:31
and hardly ever looks up from the table. Now the question is is he so racked with
00:21:36
guilt or is this somebody you know who's just being stoic and having to deal with
00:21:41
you know this verdict and now the sentencing. It's hard to say how you would interpret it. I think it's up to
00:21:47
the viewers's interpretation here. But as a parent, if that was my child saying, "I need my parent." I just can't
00:21:55
imagine not being emotional in that moment. >> Absolutely. Bob Hops received a life
00:22:01
sentence with the possibility of parole after 25 years. If he is to be released,
00:22:06
he would be 93 years old at the time. How is Rihanna grappling with this? >> She says she's trying to be strong and
00:22:14
she's trying to keep up the fight, but she's very upset. And and really at the heart of all of this, this is truly a a
00:22:20
tragic love story. It's so clear when you see from the very first frames of the home video, you know, after adopting
00:22:26
Rihanna, how much Debbie Atrops bonded with that baby. That love just screams through the screen and you can't help
00:22:35
but think all that was lost. And Rihanna says she feels that loss every day. And
00:22:41
now, of course, she's dealing with having, you know, to to lose her father in the process as well. Yeah.
00:22:46
>> So, it's it's a tragic story all around. >> Absolutely. Decades waiting for some
00:22:51
sort of justice and then there are other people involved who think there's no justice at all, but ultimately my heart
00:22:58
breaks for Rihanna and everything that she has lost. >> Yes. I mean, she's she's a strong person
00:23:03
and you know, fortunately, she has a lot of people who are supporting her through
00:23:08
this. >> Yeah, that's that's good to hear. [music] That's good to hear. Thank you
00:23:11
so much, Natalie. >> Thank you. And if you like this episode, please rate [music] and review us on
