Inside the United States Penitentiary Leavenworth: A KC Prison Historian Tells All with Kenneth LaMaster
Right outside Kansas City sits one of the most notorious buildings in American history, and almost nobody knows its real story. In this episode of Kansas City Bucket List Podcast, Mindy sits down with Kenneth LaMaster, a 31-year correctional officer and official historian of FCI Leavenworth, to pull back the curtain on the flagship of the Federal Bureau of Prisons. Kenneth spent three decades behind those 40-foot walls and has since become a go-to expert for documentaries, books, and true crime podcasts, and he brings receipts, wild stories, and zero filter. You'll hear the real history behind Leavenworth's construction (yes, inmates built it themselves), the brutal early days of American corrections, and how the prison's rotunda ended up modeled after the U.S. Capitol. Then things get dark fast: Kenneth breaks down the true story of Carl Panzram, one of the most disturbing serial killers in U.S. history; separates fact from Hollywood fiction on Robert Stroud, the "Birdman of Alcatraz"; and traces the surprising Leavenworth connection to boxing legend Jack Johnson, Chuck Berry, and Iceberg Slim. Along the way, Kenneth shares first-person stories from the job - a foiled prison break plot, a knife attack in his first month on the job, mafia confessions about Jimmy Hoffa, and an eerie CPR call he'll never forget. Whether you're a Kansas City local who's driven past those walls a hundred times, a true crime junkie, or just love a good "you can't make this up" story, this episode is one of the wildest deep dives Kansas City Bucket List has ever done.
