The Mile Zero Murders from Uncover

A police wellness check reveals one of our key sources has been compromised. Aaron Linklater’s daughter comes forward. Were the people behind Cole Hosack’s murder the people who threatened her father too? Host Timothy Sawa speaks with new sources, who take him even deeper into Dawson’s deadly drug trade. Who killed Aaron Linklater and why?

New details emerge about Cole Hosack’s disappearance. Two anonymous sources corroborate this new version of events. Host Timothy Sawa tries to verify the new information, retracing search parties’ steps, and staking out the home of the person last seen with Cole Hosack.

Host Timothy Sawa is onto Tanner Murray. That same week, a dead body is found in the back of a pickup truck – Dawson Creek’s first suspicious murder in a year. Tim shifts his focus to the prime suspect of the latest murder, who is surprisingly frank about what might be behind the violence in Dawson Creek.

Verna Cardinal recounts the last hours she had with her granddaughter, Renee Didier. She also offers a new lead – a person who knows who Renee was with the night of her disappearance. Different people then point to the same person as someone who connected with the missing and murdered before they vanished. Host Timothy Sawa connects with the RCMP to see what they know. If so many people in town suspect the same person, why haven’t charges been laid?

The remains of two missing people are found. A father comes forward with new information about his daughter’s murder. His tip leads to a story about a well-known double murder at one of Dawson Creek’s notorious trailer parks. How do the murders of Tina Nellis and Adam Roy Isley connect with Darylyn Supernant? Host Timothy Sawa finds out more about the targets of the double murder, what might have motivated the gruesome scene, and what has made Dawson such a hot bed of criminal activity in recent years.

A man passing through Dawson Creek, B.C. for New Years Eve 2023 disappears. Cole Hosack is the 8th person to go missing from the small town in the past two years. This incident starts getting media attention on this unassuming town – what is going on in Dawson Creek? Why have people, like Cole, Darylyn Supernant, and Renee Didier vanished without a trace? Host Timothy Sawa lands in Dawson Creek to find out what residents know, and talks to the relatives of people who have gone missing.

The Mile Zero Murders investigates the baffling wave of disappearances and murders in the small town of Dawson Creek, B.C., a community struggling with a deadly local drug trade. Host Timothy Sawa and CBC's the fifth estate explore missing person cases like that of Cole Hosack and Renee Didier. The question that drives this series is the same one that haunts this community: where is the justice?

The city of Akron, Ohio reels from rising violence and stalled investigations until arrests suddenly begin to happen. A mysterious new AI-powered tool called Cyber Check has arrived. Criminal defense attorney Don Malarcik first encounters the technology when it’s used to implicate his young client in a murder. With no clear explanation of how it works, and no public record of its existence, Don and his team begin digging into Cyber Check, uncovering unsettling questions about whether this powerful new technology is delivering justice—or quietly reshaping it.

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.

As Don connects with Colorado defense attorney Eric Zale, they compare notes and troubling inconsistencies emerge—Adam Mosher’s claims about his experience, expertise, and courtroom testimony don’t hold up under scrutiny. Investigators discover that key cases Mosher cited either never went to trial or never involved him at all, leading prosecutors in Colorado to drop charges rather than rely on his evidence. But in Akron, Cybercheck remains in use, and Mosher continues testifying under oath despite mounting doubts. Determined to stop what he believes is a dangerous and unverified system, Don launches a broader effort, reaching out to other defense attorneys and building a coalition to expose the truth—knowing the outcome could affect not just his clients, but the future of criminal justice itself.

Don Malarcik might finally uncover how Cybercheck works, as its creator Adam Mosher travels to Ohio to demonstrate the software to Don’s legal team and independent experts. While parts of the program appear functional, its core AI remains hidden, and Mosher refuses to provide full access or explain how it reaches conclusions that place suspects at crime scenes. His answers raise concerns about bias, and when he claims Cybercheck was peer-reviewed by a Canadian university, Don discovers the university denies any involvement. Believing this proves Mosher misled the court, Don prepares for a decisive hearing that could determine whether Cybercheck is legitimate evidence—or junk science.

Prosecutors privately begin questioning Adam Mosher’s false peer review claims, while defense attorney Don Malarcik uncovers evidence that Cybercheck reports were manually edited—contradicting claims that the system was fully automated. As the critical Daubert hearing approaches, prosecutors abruptly withdraw Cybercheck as evidence rather than defend it in court, effectively ending its use in Summit County without admitting wrongdoing. National reporting and expert analysis further undermine the technology’s credibility, comparing it to unsupported pseudoscience. But despite Cybercheck being abandoned locally and Mosher facing investigation, Don realizes the tool has silently continued to spread across the country and raises troubling questions about how easily unproven technology can influence the justice system.

Cybercheck has spread across the U.S. through aggressive cold-email marketing, word of mouth, and partnerships with law enforcement agencies eager to solve cold cases. Journalist Todd Feathers uncovers questionable claims in Cybercheck reports, including supposed access to dark web accounts and the ability to retroactively place phones at crime scenes decades earlier. Despite producing few verifiable results, respected agencies like Ohio’s Bureau of Criminal Investigation still promoted the tool to other departments, helping expand its reach. Is there anyone willing to put this tech under the necessary scrutiny? Maybe in West Texas.

In Midland, Texas, prosecutor Lisa Borden took a different approach with Cybercheck. After closely questioning Adam Mosher and finding Cybercheck lacked peer review and proper authentication, she refused to use it in court, concluding the technology was not scientifically reliable. Sam Mullins’ gets to sit down with Cybercheck creator Adam Moser. Mosher tells him his backstory as a movie buff. He explains that the technology was inspired by crime TV and movies and built with the help of government grants and technology students. And then just as COVID hit, Moser says, cyber check started reaching out to its first potential clients. But he wasn’t prepared for what happened next.

Mosher explains that his Cybercheck technology was built to analyze open-source internet data using AI to generate investigative “intelligence,” not courtroom evidence. Mosher admits the company failed early on to clearly communicate those limits, allowing prosecutors to use Cybercheck as evidence, and he acknowledges the risks of relying on AI without independent verification. However, he defends the system’s value, denies wrongdoing, and attributes criticism to misunderstandings and aggressive defense attorneys. Despite mounting doubts—including inconsistencies in his claims, refusal to share source code, and questions about peer review—Mosher insists Cybercheck remains useful to law enforcement, while the interview leaves unresolved concerns about its reliability, transparency, and continued use. Mosher tells Sam he needs to speak to the people behind the curtain who are having success with it.

Sam Mullins looks into Cybercheck’s claimed “success stories” and finds they offer little proof of the tool’s reliability. One defense attorney benefited from a Cybercheck report that actually pointed to an alternative suspect, helping reduce charges against her client, while a prosecutor and paid Cybercheck consultant praised the technology despite never using it in court. Journalists’ extensive public records requests and outreach to law enforcement revealed widespread skepticism, failed tests, and unverifiable claims, with no confirmed example of Cybercheck solving a case. The episode also highlights the conviction of Salah Maddi, where Cybercheck testimony appeared to influence the jury despite weak corroborating evidence, raising concerns that unproven AI may have contributed to wrongful convictions. Ultimately, the investigation concludes that Cybercheck has consumed investigators’ time, influenced prosecutions, and spread widely—despite a lack of transparency or clear evidence that it reliably delivers justice.
