Ed Kemper: The Co-Ed Killer
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.Be the first to know about Wondery’s newest podcasts, curated recommendations, and more!

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.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
