About the show
From CBC's Uncover. In Akron, Ohio, murder cases that went cold for years are suddenly being solved. But defense attorney Don Malarcik isn’t celebrating; he’s alarmed. The key evidence in these cases is coming from a mysterious AI tool called Cybercheck, a system so secretive that its Canadian founder refuses to explain the details of how the technology actually works. Allegedly, Cybercheck uses open-source data to place suspects at crime scenes without the need for witnesses — and while no one, not even prosecutors, understand how it works — it’s being increasingly embraced by U.S. police services and placing people in prison cells across the country.
As Cybercheck continues to spread, Don teams up with a concerned network of lawyers, investigators, and journalists to unravel what’s really powering this so-called breakthrough in crime-solving. What they find is a tangled story of lies, unvetted tech, and a charismatic Canadian entrepreneur whose invention operates in a black box.
From the makers of Sea of Lies and hosted by Sam Mullins, this season of Uncover asks: what happens when AI enters the courtroom? Who is benefitting from this mysterious technology? And who’s accountable when AI gets it wrong?
