Dr. John Schneider rode into town like a character out of a Western: an outsider on a Harley-Davidson, in trademark cowboy boots. He promised relief to patients suffering in Wyoming and Montana. He seemed like the hero they needed. But when surgeries go wrong and a strange letter exposes a bitter feud, medical professionals and government officials search for the truth about this cowboy doctor. They discover claims of broken bodies, bullying, fraud, and lawsuits.

From Audible, the fifth season of the hit series Dr. Death returns with The Cowboy: the story of a surgeon who took advantage of a broken system and the fight to bring him to justice.

Retired FBI agent and criminal profiler Candice DeLong explores the disturbing case of Sid Vicious and the unsolved murder of Nancy Spungen. On the morning of October 12th, 1978, Nancy was found stabbed to death on the bathroom floor of Room 100 at New York City's legendary Chelsea Hotel — and the only suspect was the man she loved. Candice examines how two profoundly damaged people, bound together by trauma, addiction, and a relationship built on destruction, collided in a way that left one of punk rock's greatest mysteries permanently unsolved.

Retired FBI agent and criminal profiler Candice DeLong explores the chilling case of Joanna Dennehy, a brutal serial killer inspired by the film Kill Bill. Over just ten days in the spring of 2013, three men were stabbed to death in quiet English towns, and no one could believe what they were seeing -- because the killer was a woman who hunted for sport. Candice examines how Dennehy used charm, manipulation, and a rare appetite for violence to murder for pleasure across a single brutal week -- and how one survivor's ability to identify her tattoo finally brought her killing spree to an end.

Retired 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.

Retired 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.

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.

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.

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.
