Malcolm Gladwell in The New Yorker:
In a new book, “Inside the Mind of BTK,” the eminent F.B.I. criminal profiler John Douglas tells the story of a serial killer who stalked the streets of Wichita, Kansas, in the nineteen-seventies and eighties. Douglas was the model for Agent Jack Crawford in “The Silence of the Lambs.” He was the protégé of the pioneering F.B.I. profiler Howard Teten, who helped establish the bureau’s Behavioral Science Unit, at Quantico, in 1972, and who was a protégé of Brussel—which, in the close-knit fraternity of profilers, is like being analyzed by the analyst who was analyzed by Freud. To Douglas, Brussel was the father of criminal profiling, and, in both style and logic, “Inside the Mind of BTK” pays homage to “Casebook of a Crime Psychiatrist” at every turn.
“BTK” stood for “Bind, Torture, Kill”—the three words that the killer used to identify himself in his taunting notes to the Wichita police. He had struck first in January, 1974, when he killed thirty-eight-year-old Joseph Otero in his home, along with his wife, Julie, their son, Joey, and their eleven-year-old daughter, who was found hanging from a water pipe in the basement with semen on her leg. The following April, he stabbed a twenty-four-year-old woman. In March, 1977, he bound and strangled another young woman, and over the next few years he committed at least four more murders. The city of Wichita was in an uproar. The police were getting nowhere. In 1984, in desperation, two police detectives from Wichita paid a visit to Quantico.
