Mabel’s Poison Corn Mystery

Mabel’s Poison Corn Mystery

In 1922, a bizarre and disturbing crime shook the Mabel area of Fillmore County. Former marshal Arch Gordon discovered that several of his cows had been poisoned after eating ears of corn that had been hollowed out and filled with Paris green — a deadly poison commonly used at the time as an insecticide. As rumors spread through the community, bloodhounds were brought in from Waterloo, Iowa, and investigators followed a trail of threats, grudges, and suspicious evidence. Before long, local man Dave Coonradt found himself at the center of one of southeastern Minnesota’s strangest criminal investigations. In this episode of Roots & Riddles, we explore the shocking cattle poisoning case that horrified rural Minnesota, the newspaper coverage that fueled public outrage, and the revenge-driven mystery that still feels stranger than fiction more than a century later.

When the Torch Gang Robbed the Spring Valley Post Office

In the spring of 1940, a gang of safecrackers armed with acetylene torches swept across southern Minnesota and northern Iowa — leaving behind burned vaults, stolen cash, and nervous communities. One of their boldest crimes happened in the heart of Spring Valley, when burglars broke into the local post office under cover of darkness and torched their way through two steel vault doors. In this episode of Roots & Riddles, we follow the trail of the so-called “Torch Gang,” explore the regional crime spree tied to Lanesboro, Caledonia, and beyond, and uncover the story of James Burl Johnson — the ex-con eventually connected to the robberies. From stolen welding equipment to late-night break-ins and dramatic newspaper headlines, this forgotten case reads like something out of a noir crime film.

Did the Barker–Karpis Gang bury their loot near Chatfield?

In 1934, the notorious Barker–Karpis Gang kidnapped St. Paul banker Edward Bremer and collected a ransom worth $200,000. According to local legend, not all of that money was ever recovered. Some believe a portion of the gang’s loot was buried somewhere along Highway 52 between Rochester and Chatfield — hidden beneath a fence post during the dead of a Minnesota winter. But is there any truth to the story? Or is it simply one of southeastern Minnesota’s most enduring treasure legends? In this episode, we explore the Bremer kidnapping, the Barker–Karpis Gang, and the decades-old rumors of buried gangster gold hidden somewhere in Fillmore County.
