  • Brenda Ann Spencer: The Girl Who Didn't Like Mondays

    Brenda Ann Spencer: The Girl Who Didn't Like Mondays
    Apr 21 2026
    Retired FBI agent and criminal profiler Candice DeLong explores the disturbing case of Brenda Ann Spencer, the teenager behind one of the earliest school shootings in modern American history. On the morning of January 29th, 1979, at just 16 years old, Brenda opened fire on children arriving at an elementary school across the street from her home, killing two and wounding nine others. When asked why she did it, her answer was chilling in its simplicity: she didn't like Mondays. But what investigators uncovered was not a story that began that morning – it was one that had been unfolding for years, in plain sight. Candice examines how a childhood marked by neglect, untreated mental illness, and a system that failed her at every turn culminated in an act of violence that would cast a long and devastating shadow over American history.

  • Sirhan Sirhan: The Assassin of Robert F. Kennedy

    Sirhan Sirhan: The Assassin of Robert F. Kennedy
    Apr 14 2026
    Retired FBI agent and criminal profiler Candice DeLong explores the disturbing case of Sirhan Bishara Sirhan, the man who assassinated Senator Robert F. Kennedy. Shortly after midnight on June 5th, 1968, a gunshot in the kitchen of a Los Angeles hotel changed the course of American history. What investigators uncovered was a killer unlike any other: a deeply traumatized young man whose wounds of war and loss had quietly curdled into rage. Candice examines how a childhood defined by displacement and violence laid the psychological groundwork for radicalization, and how a single perceived betrayal transformed an admirer into an assassin.

  • Ted Kaczynski: The Unabomber 30 Years Later

    Ted Kaczynski: The Unabomber 30 Years Later
    Apr 7 2026
    30 years after ""The Unabomber's"" arrest, Ted Kaczynski's ideas are more alive than ever, cited by killers like Luigi Mangione, debated by philosophers and celebrated by people who see him as a prophet rather than a murderer. Retired FBI agent and criminal profiler Candice DeLong, who sat alone with him hours after his capture, will share all-new anecdotes about Kaczynski's case, his capture, her own (not entirely accurate) portrayal in Michael Mann's film ""The Insider,"" and how we can still gain valuable insights from his case three decades later. This episode also details Ted's death, his strange afterlife in the culture, and a reckoning with the uncomfortable questions his legacy forces us to ask. Candice serves as our guide through both the past and the present — and reflects on the person she believes is the true hero of the story: David Kaczynski, the brother whose agonizing decision to turn Ted in may have saved countless lives.
