The River Killer who Escaped for Fourteen Years

The River Killer Who Escaped for Fourteen Years: The Forensic Investigation of Arthur Shawcross

A man sentenced to 25 years for murdering two children was released in fourteen. With no police record in Rochester, he began killing women along the Genesee River. When helicopters detected him over a frozen body in January 1990, he personally guided agents to victims who had been missing for months.

In this episode, we explore how the psychological profile of Agent Greg McCreery identified the serial killer through postmortem mutilations, how testimonies from sex workers linked deviant sexual behavior to eleven homicides, and why the multiple personality defense collapsed when the same man recounted his crimes coherently and with a smile to the forensic psychiatrist. Conscious psychopath or mentally ill person out of control?
