John Wayne Gacy murdered at least 33 young men and boys. But for years after his conviction, attorney Karen Conti sat across from him on death row, trying to understand the man behind one of America’s most infamous serial murder cases.

In this episode of UNMARKED, Conti describes what Gacy was really like behind closed doors: his manipulation, emotional detachment, need for control, and the contradictions that made him so difficult to fully understand. We also examine modern psychological and criminological research surrounding psychopathy, trophy-taking, victim selection, and the environmental patterns that shape serial killers.

Why did Gacy keep victims beneath his own home when most serial killers attempt to distance themselves from the crime? What did he reveal in private that the public never saw? And what happens when someone spends years speaking directly with a man the world has already reduced to a monster?

Keith Hunter Jesperson wanted to be seen. Between 1990 and 1995, the long-haul truck driver murdered women across the United States while carefully shaping the story around himself. He wrote letters to newspapers. Confessed on truck stop bathroom walls. Participated in psychological research studies about his own behavior. Even donating his brain to science after death. But beneath the “Happy Face Killer” persona is something more revealing: a man driven by grandiosity, callousness, impulsivity, and an insatiable need for recognition.

In this episode of UNMARKED, we examine the psychology of Keith Jesperson through exclusive conversations with author and investigator M. William Phelps, archival interviews with Jesperson himself, contemporary forensic psychology, and the systemic failures that allowed vulnerable victims to go unseen for decades.

Joel Rifkin confessed to the murders of 17 women in just three years—leaving their remains scattered across Long Island, New York City, and New Jersey.

And for years, no one was looking for him.

In this episode, we examine the case through the lens of N. G. Berrill—one of the first psychologists to evaluate Rifkin after his arrest. Drawing on interviews, court records, and police reports, this is a reconstruction of how Rifkin operated in plain sight—and what allowed him to continue.

From his early life in suburban Long Island, to the environments he exploited, to the moment a routine traffic stop ended it all, this episode breaks down the pattern behind the crimes.

Because this isn’t just the story of one offender.

It’s a case that exposes something larger—how vulnerable populations are overlooked, how investigations fail to connect, and how, in the 1980s and 90s, the rise of “serial killer” culture may have given offenders like Rifkin a framework to follow.
