The Expert Witness from Uncover

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.

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.

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.
