On a Saturday at noon in September 1966, Kankakee experienced a crime that felt like it was ripped from a Hollywood noir film. A gunman ambushed an armored car driver in an alleyway, abducted him, and made off with over $42,000 in cash.
But as Kankakee Police Chief Thomas Maass and his team began to investigate, they realized the call was coming from inside the house. The "victim," a young officer named Ronald Balthazor, wasn't just a driver—he was an active-duty policeman living a desperate double life.
In this episode of This One Time in Kankakee, we unpack the "inside job" that shook the community to its core. We follow the trail from the City National Bank alley to a sweltering getaway truck on the Iroquois County line, and finally to a tense polygraph test in Chicago. It’s a story of high-stakes temptation, "discrepancies" that wouldn't jibe, and a secret stash hidden behind rocks and tile along the Iroquois River.
What’s inside this episode:
- The Heist: The step-by-step "ambush" of the Kankakee Armored Car Service.
- The Double Life: How an active-duty officer maintained his facade for four days while his colleagues hunted for a phantom gunman.
- The Breakdown: The role of 1960s forensics and lie detector tests in cracking the case.
