During his twenty-five year career with the Investigative Support Unit, Special Agent John Douglas became a legendary figure in law enforcement, pursuing some of the most notorious and sadistic serial killers of our time: the man who hunted prostitutes for sport in the woods of Alaska, the Atlanta child murderer, and Seattle's Green River killer, the case that nearly cost Douglas his life.

As the model for Jack Crawford in The Silence of the Lambs, Douglas has confronted, interviewed, and studied scores of serial killers and assassins, including Charles Manson, Ted Bundy, and Ed Gein, who dressed himself in his victims' peeled skin. Using his uncanny ability to become both predator and prey, Douglas examines each crime scene, reliving both the killer's and the victim's actions in his mind, creating their profiles, describing their habits, and predicting their next moves.

Now, in chilling detail, the legendary Mindhunter takes us behind the scenes of some of his most gruesome, fascinating, and challenging cases -- and into the darkest recesses of our worst nightmares....

From legendary FBI profiler John Douglas and Mark Olshaker -- authors of the nonfiction international bestsellers Mindhunter, Journey into Darkness, and Obsession -- comes an unprecedented, insightful look at the root of all crime.

Every crime is a mystery story with a motive at its heart. With the brilliant insight he brought to his renowned work inside the FBI's elite serial-crime unit, John Douglas pieces together motives behind violent sociopathic behavior. He not only takes us into the darkest recesses of the minds of arsonists, hijackers, bombers, poisoners, assassins, serial killers, and mass murderers, but also the seemingly ordinary people who suddenly kill their families or go on a rampage in the workplace.

Douglas identifies the antisocial personality, showing surprising similarities and differences among various types of deadly offenders. He also tracks the progressive escalation of those criminals' sociopathic behavior. His analysis of such diverse killers as Lee Harvey Oswald, Theodore Kaczynski, and Timothy McVeigh is gripping, but more importantly, helps us learn how to anticipate potential violent behavior before it's too late....

America's foremost expert on criminal profiling provides his uniquely gripping analysis of seven of the most notorious murder cases in the history of crime -- from the Whitechapel murders to JonBenet Ramsey -- often contradicting conventional wisdom and legal decisions.

Jack the Ripper. Lizzie Borden. The Zodiac Killer. Certain homicide cases maintain an undeniable, almost mystical hold on the public imagination. They touch a nerve deep within us because of the personalities involved, their senseless depravity, the nagging doubts about whether justice was done, or because, in some instances, no suspect has ever been identified or caught.

In The Cases That Haunt Us, twenty-five-year-FBI-veteran John Douglas, profiling pioneer and master of modern criminal investigative analysis, and author and filmmaker Mark Olshaker, the team behind the bestselling Mindhunter series, explore the tantalizing mysteries that both their legions of fans and law enforcement professionals ask about most. Among the questions they tackle:

Was Jack the Ripper actually the Duke of Clarence, eldest grandson of Queen Victoria, or perhaps a practicing medical doctor? And did highly placed individuals within Scotland Yard have a good idea of the Ripper's identity, which they never revealed? Douglas and Olshaker create a detailed profile of the killer, and reveal their chief suspect.

Was Lizzie Borden truly innocent of the murder of her father and stepmother as the Fall River, Massachusetts, jury decided, or was she the one who took the ax and delivered those infamous "whacks"? Through a minute-by-minute behavioral analysis of the crime, the authors come to a convincing conclusion.

Did Bruno Richard Hauptmann single-handedly kidnap the baby son of Charles and Anne Morrow Lindbergh, the most famous couple in the world, or was he an innocent man caught up and ultimately executed in a relentless rush to judgment in the "crime of the century"?

What kind of person could kill six-year-old JonBenet Ramsey on Christmas night in her own home? Douglas was called in on the case shortly after the horrifying murder, and his conclusions are hard-hitting and controversial. Why, in the face of the majority of public, media, and law enforcement opinion, including former FBI colleagues, does Douglas believe that John and Patricia Ramsey did not murder their daughter? And what is the forensic and behavioral evidence he brings to bear to make his claim?

Taking a fresh and penetrating look at each case, the authors reexamine and reinterpret accepted facts and victimology using modern profiling and the techniques of criminal analysis developed by Douglas within the FBI. This book deconstructs the evidence and widely held beliefs surrounding each case and rebuilds them -- with fascinating and haunting results....
