John E. Douglas, Ed.D., entered duty with the FBI in 1970 after serving four years in the U.S. Air Force. He received investigative experience in violent crime in Detroit and Milwaukee field offices and also served as a hostage negotiator. In 1977 Douglas was appointed to the FBI Academy as an instructor in the FBI’s Behavioral Science Unit (BSU), where he taught hostage negotiation and applied criminal psychology.
In 1990 he was promoted as unit chief within the FBI’s National Center for the Analysis of Violent Crime (NCAVC). Serving in that capacity, he had overall supervision of the Violent Criminal Apprehension Program (VICAP), Criminal Investigative Analysis Program (better known as criminal profiling), and the Arson and Bombing Investigative Services Program.
Douglas was a coparticipant in the FBI’s first research program of serial killers and, based on that study, coauthored Sexual Homicide: Patterns and Motives. The University of Virginia awarded Douglas the prestigious Jefferson Award for academic excellence for his work on that study.
In 1992 Douglas coauthored the first edition of the Crime Classification Manual (CCM), the first study of violent crime to define and standardize techniques and terminology to be used by the criminal justice system and academia. Douglas again received the Jefferson Award for this research and the publication of the CCM.
Douglas has consulted on thousands of cases worldwide providing case analysis, interview and interrogation techniques, investigative strategies, prosecutorial strategies, and expert testimony. Included in the list of Douglas’s cases are Seattle’s “Green River Killer,” Wichita’s “BTK Strangler,” the O.J. Simpson civil case, and the JonBenet Ramsey homicide.
Since his retirement in 1995 from the FBI, Douglas has been providing pro bono assistance whenever possible to police and victims of violent crime. Douglas has coauthored both fiction and nonfiction books, including two New York Times best sellers, Mindhunter and Journey into Darkness. He also has coauthored Obsession, Anatomy of Motive, Cases That Haunt Us, Anyone You Want Me to Be, Broken Wings, and his newest book, Inside the Mind of BTK.
Douglas does numerous public presentations yearly, belonging to the Greater Talent Network (GTN) agency in New York. His personal Web site, johndouglasmindhunter.com, contains crime information as well as an active online discussion board.
