May 1200:49:13Tap to summarizeRetired FBI agent and criminal profiler Candice DeLong explores the disturbing case of Michael Gargiulo, known as the Hollywood Ripper. For more than a decade, women in the suburbs of Chicago and the Hollywood Hills were being murdered in their own homes, and no one saw it coming -- because the killer was never a stranger. He was the boy next door, the friendly repairman, the neighbor who waved from across the street. Candice examines how Gargiulo used proximity, access, and an unsettling gift for blending in to evade justice for fifteen years -- and how one survivor's refusal to give up changed everything.Audible subscribers can listen to all episodes of Killer Psyche ad-free right now.

May 500:47:04Tap to summarizeRetired FBI agent and criminal profiler Candice DeLong explores the disturbing case of Carl Panzram, one of the most brutal and unrepentant criminals in American history. In the early twentieth century, Panzram's trail of violence stretched across multiple continents, leaving behind at least 21 murder victims -- many of them still unidentified to this day. What investigators eventually uncovered was a killer unlike any other: a man who not only confessed to his crimes without remorse, but bragged about them. Candice examines how a childhood defined by abandonment, cruelty, and institutional abuse forged a worldview so dark and so absolute that by the time the world tried to intervene, it was far too late.Audible subscribers can listen to all episodes of Killer Psyche ad-free right now.

Apr 2800:45:46Tap to summarizeRetired 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.Audible subscribers can listen to all episodes of Killer Psyche ad-free right now.

Apr 1400:53:53Tap to summarize30 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.Audible subscribers can listen to all episodes of Killer Psyche ad-free right now.
