Episode 11 | Billy Milligan
Born and raised in a traumatic household, Billy Milligan struggled through early adulthood. His arrest for a violent crime as a teenager was only a taste of what was to come. When Billy was arrested and charged again at age 22, his lawyers noticed some concerning odd behavior, which led to Billy becoming the first person to use Multiple Personality Disorder as part of an insanity defense in the court of law.
