    Randy Kraft - The Scorecard Killer

    Retired FBI agent and criminal profiler Candice DeLong explores the disturbing case of Randy Kraft, known as the Scorecard Killer, one of the most prolific and elusive serial killers in California history. For over a decade, young men vanished along Southern California’s freeways, their deaths often mistaken for accidents or overdoses and their cases scattered across jurisdictions that never compared notes. What investigators finally uncovered was a handwritten list of 61 cryptic entries that reduced human lives to a word or two – one that detectives are still decoding today. Candice examines how an outwardly ordinary man killed for years in plain sight, and why some of the names on his scorecard are only now, decades later, finally being given back to the families who lost them.

    Joran van der Sloot - The Murder of Natalee Holloway

    Retired FBI agent and criminal profiler Candice DeLong explores the case of Joran van der Sloot, the Dutch national who spent 18 years lying his way through one of the most watched missing persons cases in modern history. In the spring of 2005, 18-year-old Natalee Holloway vanished on the last night of a graduation trip to Aruba – and for 18 years, the man last seen with her told so many stories that the truth became almost impossible to chase. Candice examines how a privileged upbringing and a psychopathic indifference to consequences produced a man who killed twice, extorted a grieving mother, and performed innocence for the world…until the truth finally ran out of places to hide.

    Charles Cullen - The Angel of Death

    Retired FBI agent and criminal profiler Candice DeLong explores the disturbing case of Charles Cullen, a registered nurse who killed patients across nine hospitals and healthcare facilities in New Jersey and Pennsylvania for 16 years. He was not a monster anyone recognized– rather, he was the quiet nurse who covered every shift, moved efficiently through darkened ICUs, and was trusted completely by the patients whose lives he held in his hands. Candice examines how a childhood defined by loss, relentless bullying, and a profound sense of powerlessness gave rise to a killer who found the one place he felt in control – and how the institutions that should have stopped him kept passing him on instead.

    Scott Peterson

    Retired FBI agent and criminal profiler Candice DeLong explores the disturbing case of Scott Peterson, the California man convicted of murdering his pregnant wife Laci on Christmas Eve 2002. On the surface, Scott Peterson had everything -- a beautiful wife, a home, and a baby boy on the way -- and none of the red flags that typically appear in a killer's past. Candice explores what was hiding beneath Peterson's flawless exterior, and how unchecked psychopathy, narcissim and indfidelity culminated in one of America's most notorious crimes.

    Listen Now: My Mom’s Murder

    Lauren Malloy was a baby when her mother, Lori, was murdered in East Providence, Rhode Island. For thirty years, no one told her. Everyone said Lori died of natural causes. Then a stranger sent Lauren a message — and the lie collapsed. Now Lauren is investigating her own mother’s murder. She’s recorded hundreds of hours of interviews with law enforcement, family, childhood friends, and people who won’t stop contradicting each other. Every answer opens a darker question. Every person she trusts seems to be hiding something. And the closer she gets to the truth, the more she realizes the people she trusts may be the ones with the most to hide. A 10-part true crime investigation hosted by the victim’s daughter. Lauren’s mission: to finally uncover the identity of Lori’s killer.

    Lindsay Clancy

    Retired FBI agent and criminal profiler Candice DeLong explores the disturbing case of Lindsay Clancy, the Duxbury, Massachusetts labor and delivery nurse who strangled her three young children: five-year-old Cora, three-year-old Dawson, and eight-month-old Callan, before attempting to take her own life. On the surface, January 24th, 2023 looked like an ordinary Tuesday: a doctor's appointment, kids playing in the snow, a family running errands. Twenty-five minutes later, it was a crime scene. In the months before that night, Lindsay's family watched her unravel under a rapidly worsening psychiatric condition, even as she kept seeking help and cycling through new prescriptions. Drawing on her own decade as a psychiatric nurse before the Bureau, Candice examines the excruciating question at the center of the case, whether Lindsay Clancy is a criminal or a woman consumed by severe postpartum mental illness; and why, twenty-five years after Andrea Yates, America is still struggling to tell the difference.

    Lori Vallow Daybell

    Retired FBI agent and criminal profiler Candice DeLong explores the disturbing case of Lori Vallow Daybell, the Idaho mother whose apocalyptic religious beliefs concealed the murders of her own two children. For months, nine-year-old JJ Vallow and seventeen-year-old Tylee Ryan were missing, and Lori offered the world nothing but shifting stories and eerie calm. Behind her, an inner circle of relatives, self-styled prophets, and her new husband had convinced each other that the people closest to them were consumed by evil spirits, and that removing them was salvation, not murder. But beneath the couple's Rexburg property, the truth was buried in shallow graves. Candice examines how doomsday theology, love bombing, and a trail of sudden deaths built the psychological architecture for one of the decade's most chilling family crimes, and why, even after conviction, the full scope of what ""Doomsday Mom"" believed still unsettles investigators.

    Luigi Mangione Pleads Guilty: What Happens Now? - A Conversation with Josh Ritter

    Retired FBI agent and criminal profiler Candice DeLong breaks down the stunning legal turn in the case of Luigi Mangione, the man who admitted to shooting UnitedHealthcare CEO Brian Thompson on a Manhattan sidewalk in December 2024. After 21 months of pleading not guilty in every courtroom, Mangione stood before a federal judge and confessed -- with no deal, no agreement, and no promises from prosecutors seeking life in prison. Candice is joined by former Los Angeles prosecutor and legal analyst Josh Ritter to unpack why a defendant would plead guilty to everything and get nothing in return, whether New York's double jeopardy laws can shut down a separate state murder trial, and what this case reveals about a country increasingly willing to celebrate an admitted killer as a folk hero.

    Richard Ramirez Part 2: An Interview with Frank Falzon

    Retired FBI agent and criminal profiler Candice DeLong revisits the case of Richard Ramirez, the Night Stalker, through the eyes of the man who cracked it. While Los Angeles dominated the headlines, it was a San Francisco homicide inspector named Frank Falzon who first put a name to one of history's most feared serial killers. Candice sits down with Falzon to trace the unlikely chain of evidence -- a stolen bracelet, a borrowed car, a reluctant informant -- that led investigators straight to Richard Ramirez, and to hear firsthand what it was like to come face to face with the Night Stalker himself. Frank Falzon's memoir, San Francisco Homicide Inspector 5-Henry-7, is available at: https://www.amazon.com/San-Francisco-Homicide-Inspector-5-Henry-7/dp/B0B72QWXLK Audible subscribers can listen to all episodes of Killer Psyche ad-free right now.

    Richard Ramirez - The Night Stalker

    Retired FBI agent and criminal profiler Candice DeLong explores the terrifying case of Richard Ramirez, the serial killer and sexual predator who turned the summer of 1985 into a season of fear across Southern California. Striking seemingly at random, Ramirez slipped into homes after dark, attacking men, women, and children with a brutality that left investigators struggling to find a pattern -- or predict where he would strike next. As the body count grew, so did the panic, until a crucial forensic clue and an extraordinary public manhunt finally brought the Night Stalker's reign of terror to an end. Candice examines the psychology behind Ramirez's escalating violence, the chaotic investigation that raced to stop him, and how one killer transformed the most intimate place imaginable -- the home -- into a source of fear for millions.

    Herb Baumeister - The Fox Hollow Farm Killer

    Retired FBI agent and criminal profiler Candice DeLong explores the disturbing case of Herb Baumeister, the Indianapolis thrift store owner whose sprawling Fox Hollow Farm concealed the remains of at least eleven men. For years, gay men were vanishing from the same cluster of downtown bars, drawn away by a well-dressed stranger who called himself Brian Smart and promised a night at his place in the country. But behind the locked gates of an eighteen-acre estate, that same man -- a husband, father, and successful businessman -- was living a secret life that his family never suspected and that investigators couldn't crack until the farm itself gave them the answer. Candice examines how a lifetime of concealment built the psychological architecture for one of Indiana's darkest crimes, and why, three decades later, the woods are still giving up the dead.

    Retired FBI agent and criminal profiler Candice DeLong explores the disturbing case of David and Catherine Birnie, the Australian couple who terrorized Perth over five weeks in 1986, abducting, raping, and murdering five women before a survivor's extraordinary courage brought them down. Candice examines how David's history of violent sexual sadism and Catherine's lifelong terror of being left behind made them not just compatible, but catastrophic -- a partnership that turned shared damage into a killing spree that shook Australia to its core.

    Gary Ridgway - The Green River Killer

    Retired FBI agent and criminal profiler Candice DeLong explores the disturbing case of Gary Ridgway, known as the Green River Killer. Beginning in the summer of 1982, young women began vanishing from a stretch of highway south of Seattle -- and for nearly two decades, the man responsible kept painting trucks, attending church, and living what looked like an unremarkable suburban life. What investigators eventually uncovered was a killer unlike any other: not a criminal mastermind, but a painfully ordinary man whose greatest weapon was the fact that no one looked twice at him. Candice examines how a deeply troubled childhood, a consuming hatred of the women he couldn't stop seeking out, and an almost inhuman capacity for compartmentalization allowed one man to commit 49 confirmed murders -- and nearly get away with all of them.

    The Murder of Jennifer Dulos

    Retired FBI agent and criminal profiler Candice DeLong unravels the disturbing disappearance of 50-year-old mother of five, Jennifer Dulos. After dropping off her children at school one morning in 2019 and failing to pick them back up, Jennifer was reported missing. But soon enough, evidence would reveal a horrifying truth: Jennifer was murdered. And authorities would soon discover that her estranged husband, Fotis Dulos, and his girlfriend, Michelle Troconis, were the suspects behind the sinister conspiracy. Candice explores how an inflated sense of self and narcissitic injury contributed to Fotis Dulos' escalating rage, and examines how partnership -- and possible coercive control -- entangled Michelle Troconis in an unthinkable plot.

    Jeffrey Dahmer - The Milwaukee Monster

    Retired FBI agent and criminal profiler Candice DeLong examines the horrifying case of Jeffrey Dahmer, one of America's most infamous serial killers. Between 1978 and 1991, young men and boys began disappearing from Milwaukee, Wisconsin, many from vulnerable communities whose disappearances drew little attention. When police finally uncovered the truth inside Dahmer's apartment, they found evidence of unimaginable brutality that shocked the nation. By the time he was arrested, 17 victims had been murdered. Candice explores how Dahmer's compulsive fantasies, profound emotional isolation, and escalating need for control evolved into increasingly gruesome crimes, and how missed opportunities by law enforcement allowed one of history's most notorious killers to evade capture for years.

    ENCORE: Revisiting Alex Murdaugh - A Conversation with Valerie Bauerlein

    After a stunning reversal, in May, 2026, Alex Murdaugh was granted a new trial for the murders of his wife and son, after the South Carolina appeals court ruled that the actions of a former County Clerk had unfairly impacted his trial. In this encore episode, Retired FBI agent and criminal profiler Candice DeLong revisits her conversation with Wall Street Journal national affairs reporter and New York Times bestselling author Valerie Bauerlein in which they discuss the whirlwind case of Alex Murdaugh.

Candice and Valerie discuss what it was like to be in the courtroom, what Valerie learned about Alex and the Murdaugh family’s influence in South Carolina’s lowcountry, and how her reporting and exclusive access came together in her book, The Devil at his Elbow: Alex Murdaugh and the Fall of a Southern Dynasty.

    Albert DeSalvo: "The Boston Strangler"

    Retired FBI agent and criminal profiler Candice DeLong explores the infamous case of Albert DeSalvo, the man who confessed to being the Boston Strangler. In the early 1960s, a wave of fear swept through Boston as women were found murdered in their homes, many of them sexually assaulted and strangled. As the body count grew, investigators struggled to determine whether a single killer was responsible or if multiple predators were operating at once. When DeSalvo emerged as a suspect, his detailed confessions seemed to provide long-awaited answers, but questions about his true role in the murders would persist for decades. Candice examines how DeSalvo’s troubled childhood, compulsive criminal behavior, and escalating violence may have shaped one of the most notorious criminal cases in American history, and why the mystery surrounding the Boston Strangler continues to challenge investigators and criminologists to this day.

    John Edward Robinson: The Internet's First Serial Killer

    Retired FBI agent and criminal profiler Candice DeLong explores the disturbing case of John Edward Robinson, known as the internet's first serial killer. For nearly two decades, women across the Midwest answered his ads, responded to his messages, and accepted his promises of jobs, shelter, and a better life – and then vanished without a trace. What investigators eventually uncovered was a killer unlike any other: a charming, calculating con man who recognized the internet's potential as a hunting ground before law enforcement even knew to look there. Candice examines how a lifetime of fraud, fabrication, and an insatiable need for control evolved into something far darker, and how a devoted husband, father, and churchgoer managed to lead a secret second life as a predator for nearly twenty years.
