Billy Milligan
First suspect acquitted by reason of dissociative identity disorder (1955–2014)
William Stanley Milligan (February 14, 1955 – December 12, 2014), also known as The Campus Rapist, was an American man who 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 campus of Ohio State University. In the course of preparing his defense, psychologists diagnosed Milligan with dissociative identity disorder. His lawyers pleaded insanity, claiming that two of his alternate personalities committed the crimes without Milligan being aware of it. He was the first person diagnosed with dissociative identity disorder to raise such a defense, and the first acquitted of a major crime for this reason, instead spending a decade in psychiatric hospitals.
Milligan's life story was popularized by Daniel Keyes's award-winning non-fiction book The Minds of Billy Milligan.

Why this record matters
“Billy Milligan” is worth following because a concise public description often conceals a longer documentary argument. Here, Billy, Milligan and First provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q1774745. VIAF identifies the subject as 50545331. The Library of Congress control number is n81051721. 4 of 4 selected statements include explicit references; 0 carry qualifiers and 1 use preferred rank. The first chronological checks are 1955 and 2014.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
