A Killer by

Written by the forensic nurse who transformed the way the FBI profiles and catches serial killers, this thought-provoking book takes an intimate look at the creation of the Behavioral Science Unit-the inspiration for Hulu‘s Mastermind documentary. In the 1970s, the FBI created the "Mindhunters" (better known as the Behavioral Science Unit) to track down the country‘s most dangerous criminals. In A Killer By , Dr. Ann Wolbert Burgess reveals how her pioneering research on sexual assault and trauma helped the FBI capture some of history‘s most violent offenders, including Ed Kemper (The Co-Ed Killer), Dennis Rader (BTK), Henry Wallace (The Taco Bell Strangler), and Jon Barry Simonis (The Ski-Mask Rapist). This book pulls us directly into the investigations as she experienced them, interweaving never-before-seen interview transcripts, crime scene drawings, and her personal insight about the minds of deranged criminals and the victims they left behind. Haunting and deeply human, A Killer By forces us to confront the age-old question that has long plagued our criminal justice system: "What drives someone to kill, and how can we stop them?"
