Uncover - S37 E2: Don’s Copy | The Expert Witness

Episode Date: May 18, 2026

In the ‘parallel universe’ of Boulder Colorado, defense attorney Eric Zale is working on a very similar case. A report claims to link a suspect to incriminating online activity, but offers no clear explanation of how it works or how its conclusions were reached. Unaware of Zale or any other Cybercheck cases outside of Akron, Don Malarcik continues to dig deeper. Don hires experts and investigators, but no one can verify Cyber Check’s methods or it’s creator Adam Mosher’s credentials. Meanwhile, prosecutors continue relying on the technology, presenting it as powerful, cutting-edge evidence. As Don prepares to challenge Mosher in court, he realizes he’s not just defending one client—he’s confronting a black-box system that could quietly reshape how guilt is determined, without transparency or accountability.

This is a CBC podcast. We begin somewhere completely different with a different guy who lives in the mountains in a parallel universe called Colorado.

My name is Eric Zale. I am an attorney in a small two-person law firm in Boulder, Colorado. Boulder is over a thousand miles away from Akron and is an even further distance culturally from Summit County's stack of unsolved murders. There isn't a ton of violent crime. There's not a lot of like homicides and home invasions and robberies and sexual assaults and stuff. That's kind of why I'm here. Just trying to raise a family and, you know, not work too hard. So this is Eric Zale, small firm, doing important work, lots of mountain biking. All right.

His entry into our story begins in 2021. When someone he never met before called him up out of the blue. and was under investigation for possession of child pornography. Zale took the case. His client turned over his computer and smartphone to the cops, and when they were given back to him, there was no child sexual exploitative material on the devices. But then, surprisingly, rather than drop the charges,

the police arrested him, and he was named in the press. In the affidavit for the arrest warrant, they had talked about cybercheck. And I had never seen that before. Zail was sent a full cyber check report by the prosecution, so he read it and tried to make sense of it. Based upon this report, they had procured evidence that my client had accessed certain C-SAM or child. sexually exploitative materials. It was baffling to him, not because of what it alleged,

but because it was the only thing they sent. The Cybercheck report was the sole piece of evidence in my case. There was nothing on the devices. There was no nexus or connection. There was nothing. All they had was Cybercheck saying, here these images are, and we got them from him. And when I saw that, I was like, this doesn't make any sense to me.

I probably would have used some profanity. But my initial gut check was that this is something that is not true. I'm Sam Mullins. And from CBC's Uncover, this is the expert witness. Episode 2, Dawn's copy. In 2021, Megan Wresh, who goes by the name, name of Breck was a prosecutor in Boulder, Colorado. I prosecuted there for a little over six years, but I've been practicing for about 15 or 16

at this point. And Breck's particular beat in the prosecutor's office was an especially heavy one, with the most monstrous crimes imaginable. I was doing tech assaults, child crimes, things like that. Difficult work made all the harder by bumping into the same issue again and again on her cases. It's not as easy as rating somebody's home and finding a thumb drive with hundreds of images of CSAM.

These online predators were getting too good at covering their tracks. You are going to have people that are very technologically savvy and look at it on the dark web or share it in these forums that otherwise might not be downloaded on your computer. But then, in the fall of 2021, Breck heard her call. talking about something new that could catch these guys when they least expected it. And so that was why Cybercheck was so attractive. Some local police in Longmont outside of Boulder had signed up for this new thing,

capable of finding the predators operating deep in the dark web, and that it could connect their actions to their real-life identities. It seemed to provide law enforcement with the ability to make that connection. It's like, oh my gosh, this is great. This is exactly what we need. But Breck couldn't help wondering. Was this something she could actually use in court?

I started to kind of dig down and see what Cyber Trek is all about and kind of educate myself a little bit more about it. When she got into it, Breck learned that the investigators had been working with, the creator of the tech himself, a Canadian named Adam Mosier. He's accommodating, he's charming, I guess, would be a good word. He's very easy to talk to. Over the coming weeks, Breck and Moser would sit and talk on video calls. He was, to his credit, quite patient in explaining Cybercheck and what it meant.

Moser appeared on her screen to be a man in his 40s. His voice was gruff, and unmistak. He was bespectacled, bald, and available. Always available to answer anything that Breck threw at him. Adam Mosher and I probably had between Zoom calls and phone calls, we probably spoke over a dozen times. Because to be candid with you, I am fairly technologically incompetent. So it was kind of an uphill battle for me because I wasn't understanding the technology.

If Breck wanted to use this thing in court, she needed to at least sound like an expert on it. But even with her own private tutor, Breck kept coming away from their conversations, still not fully grasping what she just heard. I think it's difficult to understand and sit through. This technology is not easy to break down and really understand, at least for me. The technology really is above a layperson's knowledge. Breck cut herself some slack. The world of open source information and AI is not easy stuff for a novice to get right away.

So she continued on, diligently writing her questions down for her next call with Mosher. Meanwhile, in a different part of town, Zale was looking at the same report Breck was. So I started just kind of calling around. I called a friend of mine who was a state public defense. than a federal public defender and is an expert in federal child pornography. Then I asked all my friends, basically in the metro area, not just in Boulder, but in Denver and elsewhere,

if anyone had ever heard of it. And no one had ever heard of this before. Zale wondered, was Longmont Police Department policing a sleepy population of less than 100,000 people, really the world's first crime-fighting unit to wield a game-changer? like this, it seemed unlikely. And so that's when I retained an investigator and an expert.

Zale brought them up to speed, and they set out. So we started to look into Cybercheck because no one had heard of it. So we were really starting from scratch. Across the aisle, Breck was considering hiring an investigator herself. After having interacted so much with Mosier, she began to know. notice some concerning patterns. He's very easy to talk to. He is also someone that makes promises and doesn't keep them.

Mosier has his own version of how things went down here in Colorado and elsewhere, but that's for later. For Breck in this moment, though, it felt like whenever she needed something tangible from Mosier, the same thing would happen. He continued to tell me, yes, I'll send that to you tomorrow. or I'll send you this or I'll send you that or I'll send you that specific video that I found and never did. When she'd follow up or express concerns.

I kept being given generic PowerPoint presentations and printouts generally showing cyber checks capabilities. She'd hang up the phone from Mosier and be like, we just spoke for half an hour and I gained nothing. He never actually provided anything of substance. at all. What I was getting was a very general overview of what it should be doing, and I never actually got any results that helped me verify that the information was legit. It got to the point where Breck was forced to take a step back and be like,

am I the only person that can't figure out how this is useful? So she brought on some help. And it turned out it wasn't just her. Neither the detectives nor I nor an investigator was able to actually see what we were being told. It would kind of like the emperor's new clothes. Everyone's like, check out the new fit on the emperor. Bro, that man is nude. Yeah, certainly a red flag started to go off. While the prosecutor's office were butting up against the realities of its shiny new thing,

Eric's client, John Doe, was budding up against the reality that no-man-lawed-up. matter how this turned out, his life was forever changed. Imagine one day out of the blue, you find out that the police are investigating you. And not only that, but they are investigating you and they're accusing you of this kind of crime for viewing these kinds of images of children. From the beginning had expressed his innocence, unequivocal. You have a job and a partner. and children and a community, but suddenly...

He was in the media. They're publishing your photo. Boulder is 100,000 people, right? I mean, everyone knows everyone, and an accusation of being in possession of child pornography is because everyone thinks you did it, right? First, you lose your job. He had work issues as a result of this.

And then you lose everything else. everything else. He was kicked out of the house, couldn't see his kids. And all of this happens before you've even faced a trial. That's just the simple reality, right? When the government shows up and arrests you and the judge signs off on a warrant, everyone thinks you did it. That power of that accusation is immense and life-altering.

If all of this could be done on the merit of one report, Zale and his team wanted to get to the bottom of where exactly it came from. So basically we found out it was a small Canadian company. It had a couple of people and they were claiming technology that quite frankly seemed implausible. Zales' belief that Mosher and his company were bogus continued to grow, but he didn't have anything to prove it. But then someone on Zales' new defense team did a very small, very smart thing that would prove to be tremendously useful. He said a Google alert for the word cyber check. What's that noise?

I don't know. I get that checked. Quickly. Yeah, good point. Point S, Tires and Auto Service. You think Point S has good deals on tires? Definitely. What makes you say that?

It won't shock you to learn that the copy machine is the rhythmic beating heart of any law office. When some of my friends became lawyers in our 20s, I used to imagine them center stage, starring in a courtroom drama every day, staring the jurors in the eyes, imploring them to consider their carefully spun story or eviscerating a bad guy on the stand.

You can't handle the truth, et cetera, et cetera. But over the years, usually over a shared pint, my lawyer friends will paint a much less sexy picture for me. When I ask them how their work's going, they'll say, imagine reading documents. And while you're reading the documents, a paralegal will wheel into your office more boxes of more documents, all of which are required reading,

none of which are enjoyable reading. And imagine this plays out into infinity, or at least until a landslide of banker's boxes and highlighted packets mercifully will landslide towards your desk, burying you, taking your life. Obviously, I met most of my lawyer friends at theater school. Back in Akron, Don and Marie were about to create a document landslide of their own.

They couldn't find anything on the internet to help them figure out what Cybercheck was or how it worked. So they had to settle for the only documents that they did have that explained Cybercheck. All I had at that point was Adam Mosier's transcript from both of those murder trials in Summit County. When Don went to his copy machine to print out the first two transcripts, he had no idea how many trees this Cybercheck chapter in his life would ultimately kill. He didn't know that he'd lose a whole corner of his office to an imposing stack of boxes, angrily labeled in Sharpie, cyber shit. When it began, it was just with the first 70 pages. And a prosecutor asking, could you please introduce yourself to the jury?

My name is Adam Mosher, M-O-S-H-E-R, and I'm the CEO of a company called Global Intelligence. I have a copy of this court transcript, the first ever conviction that used Cybercheck, Adaris Black, now in a cell for the rest of his life. This copy was given to me by Don. It's Don's copy. I know because it says in big block letters, Dawn's copy. Because the last thing I want to do is give my copy with all my curse words on it to the judge. Don needs somewhere to put his feelings, and that place is Don's copy. And it's an expression of how pissed off I am as I'm rating this. In the margins of Mosher's testimony, as he explains how Cybercheck works, Don's pen is emphatically writing the questions he thinks the defense counsel should have asked.

Crucial questions like, says who and what the hell? Like when Moser claims that his AI product is better and faster than human investigators. GTFOH. Moser goes so far as to say, if you have a thousand intelligence analysts and you put them in a room for 30 days, they will come up with this exact same information. F off! Don couldn't believe these statements went unchecked. You'll see a lot of WTF.

When Mosher claims that Cybercheck returns information within 80% or higher accuracy rating. You know, what the fuck? According to who? Sometimes a question mark and an exclamation point. Completely made up number, Don writes in all caps. And if I'm really pissed off, it's in red. He's using words that are just made up, right? Like cyber profile.

I mean, that's a made-up word. It wasn't just the pseudotech word. that raised Don's eyebrows. It was Moser's origin story. As the prosecutor asked him questions with the intention of presenting him as a credible witness, a very fuzzy biography began to emerge. This Canadian, who no one had ever seen before, claimed to have spent the last 20 years of his life in the, quote, cyber forensic space. He mentioned that he had a police college background and that he'd spent, quote, a lot of time at various institutions honing his skills. Accumulating what skills where, how, what, Don underlines in his copy.

While Don's copy is an exercise in giving something your least generous read, when I read it, it struck me a little differently. To me, Mosher does seem to speak ably, articulately even. Maybe he doesn't have a gift for breaking things into layman's terms for a jury, but he speaks exactly like what he says he is, a tech savant who'd made something that the world had never seen before, something capable of scouring the entire internet, which would retrieve only the pertinent morsels of information, and then lay the goods at his feet like a hound to its master.

The tech was inside baseball. But Mosier, at least, from Don's perspective, was something he could get started on. A physical human he could be looked into. So Don flipped through his rolodex to hit up one of his overqualified PIs. Former police officer, former employee of the Summit County Prosecutor's Office, was a private investigator for us. How can this Moser dude, who claims to have worked extensively with law enforcement, have no trace of anything about him anywhere.

I said, here's Mosier, here's his CV, help me out, man. What's going on? By this point, Don had read and reread the transcripts of Moser's testimony from the murder trials a dozen times. And each time, there would be new details that would pop for him. Mosier, for instance, said that he had like a satellite office in Indiana. and I said to my investigator, go find this place.

Is it a real building? I mean, what the fuck is going on? Are there employees? Are there people there? What is it? And who is he? There have to be some employees. Someone bumps into Mosier in the elevator.

Find that person and talk to them. So with his notebook, the investigator set out to see what he could find. But when he came back to Don, it was with a shrug. It was like chasing a ghost. The PI explained that even when he did manage to track down people in Moser's orbit,

he couldn't get anything out of them. He was so elusive and we really couldn't get much traction. It was really like trying to grab on to smoke. Meanwhile, in Boulder, Eric Zale finally went to see Breck Resch in the prosecutor's office to offer her his professional opinion. I think I told the prosecutor that he's a grifter. when you have a defense attorney who says your expert is a total fraud,

you kind of chuckle and say, okay, like, you need to provide me a little bit more information than that. And Eric's like, no, you need to provide me with more information. I want the algorithms and the information of his software so that I can try to replicate this. Because the report that you've given me, I don't believe that he has the ability to produce this based upon what he's claiming. You're saying that you can prove that my client went to these parts of the internet to look at these types of illegal materials, and you did this through legal means. Prove it then.

The prosecutor basically said he won't give it to me because it's proprietary. Wait, even the prosecutor's office hasn't been shown how it works? So Zale was like, screw this. I'm going to the judge. And I said, hey, judge, they need to give me not just this report, which is like prima facie implausible. Lawyers love their Latin. They need to give me the backstory to the report. I need the data.

And I also need a bunch of other stuff as well. I need to know what other cases this was used in in the country because I need to look up to see what happened. And also, we need to figure out whether or not Mosher has ever been in a courthouse before. I need to know if he's been qualified as an expert. The judge was mostly unmoved. She said, You don't get the algorithms. You're not entitled to it at this stage.

The judge sided with the prosecution, but Judge Salimony was very specific that she wanted a list of the cases where Adam Mosher had testified as an expert. which is ultimately what broke the case apart. Meanwhile in Akron, Don and Marie were working on the case of teenager Javion Rankin and had been having some very similar conversations in their parallel universe. Give me the software. Give me the algorithms. Give me the AI that Adam Mosier says does this incredible feat of putting my client at the scene of the crime.

I need to examine it. The response we got was from the problem, prosecutor's office is, well, he doesn't work for us, so we don't have it. Oh, you don't have the thing that places my client at the murder scene? I'm like, oh, fuck you. I mean, this is your evidence. You want to submit it. You've got to go get it. And they just refused. By now, it's early summer 23, more than two years since JVion Rankin had been sat in a cell. And now a hearing on his case was scheduled that was to be attended by the judge, the prosecution, Don, and a surprise guest. So I was in my office, everybody was remote, no one was in the courtroom, and I said,

I don't even know if they're going to bring Mosier to this hearing. And if they do, should I cross-examine him? And Noah was like, no, why are you going to give that person an opportunity to speak? Keep it simple. All you need to put out there is that this tool is unproven and untested. Get cybertech thrown out. Get JVion home. Mojure appeared on the screen with his background blurred and scanned very plausibly as the CEO of an AI tech company, the perfect mix of tech geek and mirthless measured law enforcement agent. And they just start asking Adam questions. As Moser spoke, Don felt that familiar WTF energy that had so possessed him in the margins of Don's copy. Every time he would move on to a new topic, it didn't really pass the smell test.

Noah and Marie shared an eye roll as they listened to Mosher. It's like digital goblygook speak. The intelligence loop cannot be broken. It can only be completed. What does that mean? If the tools are a quiver and this is an arrow. None of it makes any sense to me. And it's these protracted analogies. And so you never really get the thing. Eventually, Don couldn't help himself. I knew I had to jump in and get in the ring with him and try to figure out what the hell this thing was.

I was really kind of winging it, and I realized very quickly that Adam can't answer a yes or no question. It's impossible. Don would ask a question, and Moser would just start monologuing again. I would stop him and say, Adam, do you remember the question I asked?

And sometimes he wouldn't even remember the question. I know, as someone who's been cross-examining people for 30 years that that's a sign that they're lying. It was a risk to cross Mosier, but this was exactly how Don hoped it would go. So now I'm watching the judge, and I see the judge getting a little bit irritated, and now I know I'm onto something.

But then, with Moser flailing for all to see, the hearing came to an abrupt end, and Don stood unsteadily, not knowing if any of the spaghetti he'd just thrown into the virtual courtroom would stick. The good news, came shortly after. Judge Rollins said she was going to grant the motion to compel

and order Adam Mosier to provide his software. The only way that she would allow Cybercheck to be used as evidence in this case was if the defense could see inside it, if Don was given full access to its source codes and algorithms. And Mosier was steadfastly refusing. And even better, while the prosecution was making an appeal. What must happen is the defendant, the accused, must be released on a signature bond. Javion Rankin was free to leave jail and go home.

At least for now. When you're a defense attorney, the victories can feel cruelly infrequent. But this, this was a good one. In Don's view, the police threw some weird Canadian technology. at him and Don was able to dekembe Matumbo it out of here. Javion Rankin had to wear a judge-ordered ankle monitor, but he was out. This was the system working, right? Okay, we got to be done, but we're not.

Time would reveal that the Rankin case was but one shiny star in the galaxy of what Summit County had planned for their shiny new AI tool. The tell was sitting right there. Why did they appeal the judge's decision to throw cybercheck out? Why did they let someone charged with aggravated murder walk with a signature? Because they had big things in the queue. By this time, I have a second murder case, Deshaun Coleman, and I get a cybercheck report in that case, too.

And Deshaun Coleman wasn't the only defendant in Akron with a cybercheck. report appearing in his case file. All over town, other lawyers, like the attorneys for Philip Mendoza, Martel King, Ledley Lopez, Bobby Lee Bell, Dierre Ray, Antonio Miller, Rita Case, and Demonte and Demetrius Carr were now seeing it too. Mostly black male defendants who'd been arrested on cold case murders, not because of new witnesses, DNA evidence, or the emergence of a new motive,

but because Cybercheck had pointed in their direction. It wasn't until they utilized the new aid, and they were able to arrest him. But as luck should have it, Don's local newspaper did something that set off a very fortuitous chain reaction. They published a story about this Javion Rankin win, and that story acted as a flare. which set off a Google Alert in a small office in Colorado, set for the word cybercheck.
