A former FBI investigator and the author of Mindhunter offers a glimpse of some of his most complex cases and demonstrates the way in which criminal profiling works, covering such crimes as John Lennon's assassination, the Waco tragedy, and New York's preppie murder. Some of the unique cases Douglas discusses include: The Clairemont killer -- Six women were found stabbed to death in San Diego, three in the same apartment complex. In each case, the killer entered through an unlocked door or window in the late morning to early afternoon. A suspect was in custody, tied to one of the murders through a DNA match. Douglas was called upon to use his profiling techniques to link the other five murders to the suspect. Douglas looked at the "signature" of the killer, and found that all the murders were committed by the same man. The prosecution used the profile to force the jury to find the defendant guilty of all six murders, if they felt he was guilty of the one murder. Celophus Prince was found guilty on all counts. The schoolgirl murders -- What became Canada's "trial of the century." Several schoolgirls disappeared in 1992; their bodies were dumped several weeks later, beaten and sexually attacked. Canadian police agencies contacted the FBI for help on the case and to get a profile on the killer and, according to witnesses, his accomplice. Following the advice of the Investigative Support Unit in Quantico, Canada aired a television special entitled "The Abduction of Kristin French," allowing agent Gregg McCrary to describe the killer's profile on air. Knowing that the murderer and his accomplice would be watching, he planned to confront the unknown killer, assuring him he would be caught. Paul Bernardo was arrested on February 17, 1993, turned in by his wife and partner in crime, Karla Leanne Homolka.. The profile was dead on the money. Richmond's First Serial Murderer -- In 1987, Richmond, Virginia, was struck by a serial rapist/murderer. The Richmond police called upon the Investigative Support Unit in Quantico to make up a profile of the perpetrator. The crimes and profile bore a remarkable resemblance to a string of burglaries, rapes and murders in Alexandria, Virginia, several years before. Agent Steve Mardigian then formulated a complex strategy that caught the killer who fit the profile to a tee. In the process he helped free a wrongly convicted man, who due to his low intelligence level, had become confused and confessed to the crime. The brutal and sadistic murder of Suzanne Marie Collins, a beautiful young Marine on the verge of a brilliant career. The culprit was caught and confessed to her killing, but his story was very different than what really happened. By delving into Sedley Alley's mind, Douglas helped bring the murderer to justice, recreating the evening from the perspective of a sadistic and angry man. Suzanne Collins' horrifying end haunts Douglas to this day. Douglas delves into other cases, including Polly Klaas' abduction and murder by Richard Allen Davis, the tragedy that lead to the creation of Megan's Law; the abduction and murder of six-year-old Cassandra Lynn Hansen, who was snatched from an evening church service; and the vicious murder and sexual assault of Nancy Newman and her two daughters, eight-year-old Melissa and three-year-old Angie in Anchorage, Alaska. He also explores the murders of Nicole Brown Simpson and Ronald Goldman, focusing on the double homicide purely from a behavioral perspective. Douglas examines what the facts at and surrounding the crime scene told about the killer from a behavioral point of view. From Douglas's profile, the only viable suspect to date is O.J. Simpson. With Journey into Darkness, Douglas provides more than a glimpse into the minds of serial killers; he demonstrates what a powerful weapon behavioral science has become.
