  • The Cipher in the Cornfield: The Case of Ricky McCormick
    May 29 2026

    When 41-year-old Ricky McCormick was found dead in a Missouri cornfield in 1999, it seemed like a tragic end for a vulnerable, functionally illiterate man. But twelve years later, the FBI shocked the world: tucked in Ricky’s pockets were two notes containing a highly sophisticated, uncrackable cipher.

    ​The feds claimed Ricky had been writing in secret code since childhood. But his mother, Frankie Sparks, flatly denied it, stating plainly: "The only thing he could write was his name. He didn't write in no code."

    ​We break down the eerie rhythm of the text, the street theories tying it to a 90s St. Louis drug ring, and a terrifying question: Was Ricky living a profound double life, or was this uncrackable code a brilliant red herring planted by his killers to send the FBI down a decades-long rabbit hole?

  • The Sheath Left Behind: The Idaho Murders
    May 22 2026

    On November 13, 2022, a sleepy college town in northern Idaho was paralyzed by an act of staggering, cold-blooded brutality. Four vibrant young lives inside an off-campus home on King Road were extinguished in less than twenty minutes by a silent predator moving through the dark.

    ​This episode we dissect the deeply chilling forensic puzzle of the Idaho student murders. We walk through the terrifying, minute-by-minute timeline, look closely at the devastating accounts and forgotten texts of the roommates trapped inside the house, and track the meticulous digital dragnet that led investigators across state lines to Bryan Kohberger. A Ph.D. student studying the very mechanics of murder.

    ​Though a surprising legal resolution finally caged the monster, the psychological shadows of this case refuse to lift. Where is the weapon? What was the true connection? And what happens when the dark mind studying crime decides to become the criminal?
