The Expert Witness from Uncover

S37 E3: Ducks in a Row | The Expert Witness

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.

S37 E2: Don’s Copy | The Expert Witness

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.
