Former FBI Serial Crime Expert, John Douglas’ book is called “Mindhunter”. In it, Douglas recounts some of his cases involving several of the most notable serial killers of our time. He talks about the science behind criminal profiling and the patterns of behaviour adopted by perpetrators. Douglas was the model for Jack Crawford in “The Silence of the Lambs,” and later acted as consultant of the movie “Mindhunter.”
An interesting interview with Mark Hilts, supervisory special agent for the FBI BAU-2 (specializing in profiling serial killers).
