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 o... more

    I’ve been listening to quite a few CBC podcasts lately and this one, far by, stands out above the rest. His reporting style and storytelling was excellent!

  • Mullins is the real deal

    I’ve heard three series so far that he has written and reported. They have depth, expanse, nuance, and significance. Perfectly crafted complex narratives with a momentum that makes me binge.

  • GRIPPING. PHENOMENAL!!

    What a gripping, twisty-turney, heart-rending thriller of a story! Also, while of course there are murders discussed in this, it doesn’t feel exploitative of someone’s misery the way that true crime podcasts sometimes can.

    Sam Mullins’ ability to be both funny but also never disrespectful to the content is unparalleled. I could not put this podcast down, as it were. Going to be recommending it to all my friends, and to you too!

    PS at the risk of cheapening my praise… I’m sure I’m not alone in... more

  • Review from Wales

    I’m from Wales so thank you Sam for mentioning the principality. Anyway I came across the show by chance and am glad I did. Sam is a great presenter and the show is excellently researched. I really enjoyed the interviews with the Ohio defence attorney who first challenged the use of Cybercheck by law enforcement. The use of AI in murder trails that could result in the death penalty without the necessary safeguards is scary.

  • Fantastic host & story

    I have listened to every CBC crime show. Sam Mullins is my new favourite host! Funny, a little silly, yet so authentic. The host can make or break the show. The story was super interesting, but Sam made it a masterpiece!

The Expert Witness Introduces: The Big Bet
Q: Was it in the back of your heads that ultimately this would be a great sports betting business and maybe DFS could be a stepping stone?
Nigel Eccles says the possibility was part of the thinking: the United States had a large sports-loving population but sports betting was illegal, unlike the trend toward regulation in other countries.
Episode 8: Pick your side. Pick your story.
Q: Where does Cybercheck draw its data from, and how can you address concerns about bias?
Mosher explains that Cybercheck returns data like IP addresses and email accounts rather than facial recognition, yet the team acknowledges the potential for confirmation bias and the necessity of independent corroboration.
Episode 8: Pick your side. Pick your story.
Q: How many cases are you currently running through Cybercheck?
Mosher provides a precise, sometimes fluctuating number, illustrating a pattern of issuing specific figures while acknowledging discrepancies and the lack of external proof.

Frequently Asked Questions About The Expert Witness

What is The Expert Witness about and what kind of topics does it cover?

A hard-hitting, investigative series centered on the use of an opaque AI tool in real criminal cases. Through courtroom confrontations, FOIA fights, and expert critique, it interrogates how technology marketed as groundbreaking can influence investigations, charges, and verdicts — often with insufficient transparency.

Potential listeners who want to understand the intersection of AI, law, and justice, or who seek cautionary tales about unvetted tools in high-stakes settings, are likely to find this compelling and highly practical for framing similar iss... more
