His twisted confession reveals new insights into what led Jeffrey Dahmer – known as the Milwaukee Cannibal - to rape, kill and dismember 17 young men between 1978 and 1991. In a heart-wrenching interview, his father, Lionel Dahmer, further details his attempts to get his son the help he so desperately needed. Home video footage from Dahmer’s childhood offers an intimate look into his relatively normal upbringing, putting Dahmer as an outlier of a typical serial killer’s psyche, and shining a disturbing yet tragic revelation about his motives. Other notable interviews throughout the special include: Ronald Flowers, one of Dahmer’s victims who somehow avoided being murdered, Dr. Park Deitz, a forensic psychiatrist who spent considerable time with Dahmer, and an exclusive, never-before-seen interview with Nicole Childress, a witness who tried in vain to save one of Dahmer’s victims and lives with the guilt of that night forever. This feature-length documentary is the fourth instalment in Arrow Media's Mind of a Monster anthology series for ID.
