S37 E5: Unscrambling Eggs | The Expert Witness
Yesterday00:33:54Summary readyProsecutors 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.Binge all 9 episodes of this season on our YouTube page, or get them ad-free on CBC True Crime Premium on Apple Podcasts.A listener's guide to Uncover: Where to go next
SummaryS37 E4: Nerds Love Code | The Expert Witness
1w ago00:26:59Summary readyDon 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.Binge all 9 episodes of this season on our YouTube page, or get them ad-free on CBC True Crime Premium on Apple Podcasts.A listener's guide to Uncover: Where to go next
SummaryS37 E3: Ducks in a Row | The Expert Witness
2w ago00:32:42Summary readyAs 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.Binge all 9 episodes of this season on our YouTube page, or get them ad-free on CBC True Crime Premium on Apple Podcasts.A listener's guide to Uncover: Where to go next
SummaryS37 E2: Don’s Copy | The Expert Witness
3w ago00:31:58Summary readyIn 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.Binge all 9 episodes of this season on our YouTube page, or get them ad-free on CBC True Crime Premium on Apple Podcasts.
