In the early 1970’s, F.B.I agent, John E. Douglas, created and managed the FBI's Criminal Profiling Program, now called the Behavioral Analysis Unit. Agent Douglas became the inspiration for the character Jack Crawford in “The Silence of the Lambs,” played by actor Scott Glenn.

Douglas has interviewed numerous serial killers and other violent sex offenders at various prisons, including David Berkowitz, John Wayne Gacy, Charles Manson andothers.

In the late 1990’s he formed a partnership with author and documentary producer, Mark Olshaker, called MINDHUNTER, INC. Together they wrote numerous True Crime books, based on John’s experiences in the field. One of their books, Mindhunter: Inside the FBI’s Elite Serial Crime Unit was the basis for the popular Netflix series, of the same name.

Author and Mindhunter, Mark Olshaker, joins me today on Murder Most Foul.
