Retired agent and former FBI profiler Dr. Mary Ellen O'Toole, Ph.D., who is recognized as the FBI's leading expert in psychopathy, reviews the case of the Green River Killer Gary Ridgway, who was convicted of killing 49 women. Mary Ellen worked in the Bureau's prestigious Behavioral Analysis Unit (BAU) where she consulted on many of the FBI's highest profile and most complex cases, including homicides, kidnappings, sexual assaults, predatory behavior, child molestation and other crimes of violence. Her book Dangerous Instincts: How Gut Feelings Betray Us introduces the right way to assess people for everyday situations in our personal and professional lives, and how to make safer decisions about them and the situations they create for us.
