Discovery of Milligan's multiple personalities

The discovery of William Stanley Milligan’s multiple personalities began not with a confession or a formal diagnosis, but with a sequence of interviews in which the person before psychologist Dorothy Turner seemed to change in identity, manner, and memory. What first looked to Turner like a series of puzzling encounters became a disclosure that altered the defense strategy: Judy Stevenson and Gary Schweickart had to consider whether their client’s shifts reflected a mental condition rather than calculated behavior, and the court eventually confronted the consequences of that distinction.

Clinical and Legal Background

Before Turner’s interviews, Stevenson and Schweickart had continued visiting Milligan in prison despite receiving a letter dismissing them. The public defender’s office funded a psychological evaluation, and clinical psychologist Willis C. Driscoll administered tests on January 8 and 13, 1978. The intelligence tests yielded a score of 68, which Driscoll said had been lowered by depression. His report diagnosed acute schizophrenia and described a severe disturbance of identity, difficulty distinguishing the self from the environment, and an inability to understand events or assist adequately in his defense. He urged hospitalization for further examination and possible treatment.

On January 19, Stevenson and Schweickart presented Driscoll’s report to Judge Jay C. Flowers as evidence that Milligan could not assist in his own defense. Flowers directed the Southwest Community Mental Health Center in Columbus to assign its forensic psychiatry unit to examine him. This referral created a legal problem alongside the clinical one. Schweickart wanted anything Milligan said during the examination treated as privileged and unavailable for use against him; the prosecutors objected, and the public defenders considered advising Milligan not to speak with the court-appointed clinicians. The compromise limited questioning about potentially incriminating statements to a circumstance in which Milligan took the stand in his own defense. The defense accepted the risk and permitted the evaluation to proceed.

Turner’s Interviews and the Emerging Evidence

Turner’s first interview at the Franklin County Jail was scheduled for January 31, 1978. Milligan entered in a blue jumpsuit, appearing to Turner to be a tall, handsome young man whose eyes showed fear. Once seated, he smiled and folded his hands. Asked where he lived, he could not answer. When Turner supplied a number, he rejected it as belonging to Billy, then identified himself as David and said Billy was asleep. The exchange gave Turner more than an unexplained lapse: Milligan distinguished himself from Billy and spoke of Billy as someone absent from the immediate conversation.

The next day, Turner saw a different manner and heard a different voice. Milligan initially gave no sign of recognizing her, sat with his knees drawn up, and then spoke in a boyish Cockney accent. He identified himself as Christopher rather than David. When asked about siblings, he said that he had a three-year-old sister named Christene. Turner noted how open, earnest, and happy Christopher seemed in contrast with the person she had interviewed the day before. The changes in accent and bearing were observable; at this point, Turner was still trying to understand what they meant.

On February 4, the young man who entered the interview room sat slouched and looked at Turner arrogantly. He denied ever having seen her, although she had interviewed him two days earlier, and gave his name as Tommy. When Turner tried to draw him out, he remained sullen and refused to talk to a stranger. After leaving the jail, Turner was caught between a promise to David not to reveal the secret and her conviction that Milligan’s attorneys needed to know. She telephoned Stevenson and suggested that she read Sybil, a book that would help her understand the kind of possibility Turner was trying to communicate.

Disclosure to the Defense

Stevenson had previously been allowed to meet Allen under a strict condition: she could tell no one except Judy, and Judy in turn could tell no one else. Turner went directly from the prison to the public defender’s office and explained the limits Milligan had set. Stevenson recognized the difficulty of keeping the information from Schweickart, but she had given her word. The discovery therefore entered the defense cautiously, as information Turner believed essential but was not free to circulate without Milligan’s consent.

After Stevenson met the different personalities, she concluded that she had encountered two different people, not simply one person in changing moods. She understood why Milligan’s behavior had seemed so variable, but Turner warned that Milligan might not permit the secret to be shared more widely. Stevenson argued that she could not carry the knowledge alone. Arthur later agreed to let her tell Schweickart only if the others agreed as well. Three days later, Stevenson obtained permission and returned to the office to explain that she had something important to tell him about Billy.

Schweickart initially rejected the idea as a con, despite his confidence in Stevenson’s judgment. The following day he accompanied her to the jail expecting a brief visit. Instead, he saw what he understood as a succession of personalities. The frightened David changed into the shy Danny, who remembered the day Milligan had been brought in and booked. For Schweickart, the change transformed an abstract report into direct experience. His skepticism gave way to curiosity, and the defense now had to reckon with a condition that could affect both Milligan’s present ability to participate in proceedings and the legal interpretation of the charged acts.

Recognition, Evaluation, and Legal Consequences

The disclosure did not immediately produce agreement among all the personalities. When Schweickart asked to meet Ragen, Arthur moved his chair to the far end of the interview room, became distant, and shifted from a stiff-backed posture into a wary crouch. The new speaker used a low, harsh voice and a Slavic accent, and opposed revealing the secret even after David had disclosed it by mistake. The scene made the internal disagreement part of what the lawyers had to understand: disclosure was not simply a fact supplied by one consistent speaker, but a contested decision among identities with different positions.

Other encounters supplied further observable contrasts. Allen took a final drag from a cigarette before Arthur appeared; Arthur did not smoke. His eyes went blank, his eyelids fluttered, and he leaned back, joined his fingertips into a pyramid, and spoke with an upper-class British accent. Attorney Bernie Yavitch perceived a distinct difference in eye contact and body language. These details did not by themselves settle a diagnosis, but they accumulated as behavioral evidence that the defense could not easily reconcile with an ordinary change of mood. Turner’s early impression of Christopher and the lawyers’ later observations of Arthur and Ragen extended the pattern beyond the first three interviews.

The legal consequences must be distinguished from the initial discovery. The January evaluation concerned Milligan’s condition at the time and whether he could understand proceedings or assist his lawyers. At trial, Judge Flowers separately considered his mental state when the charged acts occurred. The judge dismissed the first rape count for lack of corroborating evidence and a similar pattern of conduct. On counts two through ten, the medical evidence was stipulated; Flowers found that Milligan had been mentally ill at the time, unable to distinguish right from wrong, and unable to refrain from the acts, and therefore found him not guilty by reason of insanity.

The later court findings made the diagnostic significance of the discovery explicit. On December 10, 1979, the court described Milligan as mentally ill, identified his condition as multiple personality, and ordered hospitalization on the grounds that he posed substantial risks to himself and others and needed treatment. The finding did not erase the earlier distinction between present competence and responsibility at the time of the offenses; it showed how the emerging account of his identity became central to both legal questions and the disposition that followed.

Significance of the Discovery

The sequence also changed how Milligan’s behavior could be read. Before Turner’s interviews, his shifting conduct could be attributed to depression, manipulation, or instability. Her questions elicited a more disruptive possibility: the names and voices were accompanied by failures of recognition and claims that Billy was asleep or absent. Stevenson’s realization and Schweickart’s eventual observation show how the discovery moved from clinical encounter to shared knowledge within the defense team, despite the secrecy and legal risks surrounding it.

The account later connects this recognition to family memory. During a visit, Milligan’s mother recalled that he had seemed able to sense things, and Kathy called this ESP; their mother also remembered that the two siblings could sometimes know what was happening in each other’s minds without speaking. This recollection does not establish a clinical explanation for the personalities. It does, however, place the new diagnosis beside earlier experiences that the family had noticed but understood differently. The discovery thus reorganized the meaning of behaviors that had previously appeared disconnected, while leaving the clinical judgment, the legal findings, and the family’s interpretations distinct.
