Billy Milligan

Who is Billy Milligan?

William Stanley Milligan, known as Billy Milligan, was the subject of a highly publicized court case in Ohio in the late 1970s. After having committed several felonies including armed robbery, he was arrested for three rapes on the Ohio State University campus. In the course of preparing his defense, psychologists diagnosed Milligan with multiple personality disorder. His lawyers pleaded insanity, claiming that two of his alternate personalities committed the crimes without Milligan's being aware of it. He was the first person diagnosed with multiple personality disorder to raise such a defense.
