Killer Psyche

Retired FBI agent and criminal profiler Candice DeLong examines the heartbreaking murder-suicide of Phil and Brynn Hartman, whose seemingly charmed life masked a growing storm. Within their home, Brynn battled addiction, insecurity and a fragile sense of identity that increasingly threatened the stability of their marriage. As tensions mounted, emotional volatility turned dangerous, culminating in a night of irreversible violence. Candice explores the psychological fractures that led Brynn to kill the man she loved, and how their relationship became a chilling example of what can happen when untreated turmoil meets opportunity for harm.

Brynn Hartman & the Murder of Phil Hartman

Retired FBI agent and criminal profiler Candice DeLong unravels the horrifying case of Gwendolyn Graham and Cathy Wood, also known as the “Lethal Lovers.” Inside the walls of a Michigan nursing home, their romance became intertwined with violence, as the pair used murder as a way to deepen their emotional and sexual bond. Over several months, vulnerable patients became targets in a shared, intimate thrill – a lethal fusion of affection, manipulation, and desire. Candice explores how their toxic dependency escalated into a series of killings, and how a relationship built on control, obsession, and the pursuit of shared gratification spiraled into one of the most disturbing partnerships in criminal history.

Gwendolyn Graham & Cathy Wood: The Lethal Lovers

Retired FBI agent and criminal profiler Candice DeLong examines the chilling case of Elliot Rodger, the self-described “supreme gentleman” whose violent resentment toward women exploded into a deadly rampage in Isla Vista, California, in 2014. While frequenting self-validating incel forums online, offline, Rodger struggled with social rejection, mental-health crises, and a growing obsession with punishing the people he believed had wronged him. By the time the violence erupted, six people were dead and fourteen more injured. Candice explores how alienation, narcissism, and extremist online communities converged to create a perfect storm; and how Rodger’s attack marked a turning point in understanding grievance-based violence, misogynistic extremism, and the psychology behind modern lone-actor killers.

In October 2021, the social media influencer brutally killed his estranged wife, Ana, and her friend, Ray Barron, inside a San Diego high-rise apartment. At first, Abulaban appeared to have it all: fame, followers and a picture-perfect family. But beneath the curated clips and comedy skits was a man consumed by jealousy, rage and a desperate need for validation. His obsession with his online persona was so overpowering that he secretly recorded his wife- and even captured the sound of her final moments.

Ali Abulaban: The TikTok Murderer

Retired FBI agent and criminal profiler Candice DeLong explores the disturbing case of Ed Kemper, known as “The Co-Ed Killer.” In the early 1970s, young women began vanishing from the streets of Northern California. When the truth finally came to light, it revealed a killer unlike any other: a towering, soft-spoken man whose charm and intellect hid monstrous impulses. By the time he was caught, eight people – including his own mother – were dead. Only later would investigators learn that Kemper’s knack for violence began years earlier. Candice examines how deep resentment, emotional isolation, and a fractured relationship with his mother fueled one of the most chilling killing sprees of the decade, and how his later cooperation with the FBI helped shape modern criminal profiling.

Ed Kemper: The Co-Ed Killer

Retired FBI agent and criminal profiler Candice DeLong dives into the infamous case of Bryan Kohberger. In November 2022, four University of Idaho students were brutally murdered in their off-campus home, kicking off a six-week manhunt that captivated the world. When investigators traced DNA evidence and digital data back to Kohberger, a criminology PhD student studying the psychology of killers, the story took an even darker turn. Candice examines how Kohberger’s lifelong social isolation, feelings of rejection, and status as an outcast may have fueled a deep psychological need for power and control, and how his fascination with criminal minds may have ultimately led him to become one himself.
