What drove the inconspicuous sociopath to become a ruthless killer? During his nearly fifteen-year reign of terror, Ronald Lloyd Bailey’s depraved obsession with sexual sadism held communities across southeast Michigan in a shroud of fear. From the early 1970’s to the mid-1980’s, the former patient at one of Michigan’s foremost psychiatric hospitals, abducted as many as fifteen teens and over time became a sadistic serial killer. In this shocking, fast-paced account, retired police officer and true crime author Rod Sadler examines law enforcement's dedicated efforts in connecting the dots to stop an unknown killer, and he poignantly chronicles the determination of the victims' families to triumph over tragedy. Sadler also examines Bailey’s insanity defense that centered on the alleged abuse he endured at the hands of his psychiatrist. In doing so, the bestselling author of KILLING WOMEN asks and answers the question: What drove the inconspicuous sociopath to become a ruthless killer? "Depraved Obsession is a haunting, meticulously researched journey into the mind of a predator and the heroic determination of law enforcement to stop him.
