The Cipher in the Cornfield: The Case of Ricky McCormick

from True Crime on the Brain · host True Crime on the Brain

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?
