Stella Karolin

Stella Karolin is a medical expert whose evaluations and courtroom testimony supported the diagnosis of Billy Milligan with multiple personality. She argued that treatment should begin with that overarching condition, even if individual personalities might have other mental illnesses. Her role linked repeated clinical observation to the legal and institutional decisions about Milligan’s care.

Clinical Assessment

Karolin had seen Milligan in April, June, and July of the year of the hearing. By July, she felt that he remained split. Her view was not presented as a diagnosis reached in isolation: she testified that she had independently arrived at the same diagnosis as Dorothy Turner, Cornelia Wilbur, and George Harding.

Testimony and Treatment Priorities

Karolin’s evidence formed part of a larger body of expert opinion concerning Milligan’s state during the roadside-rest assaults and the Gray Drug Store robbery in December 1974 and January 1975. In depositions submitted to the court, Karolin and the other clinicians agreed that there was a reasonable medical certainty Milligan had been mentally ill with multiple personality when those offenses occurred. They also agreed that he probably had not been able at that time to assist his attorney in his own defense.

At the hearing, Karolin resisted treating possible additional diagnoses as the first priority. She said that different personalities might have different illnesses, but that the multiple-personality condition as a whole should be treated first. This position kept the central diagnosis in view without claiming that it ruled out every other problem.

Support for Milligan’s Care

Karolin was asked whether Milligan had been receiving correct treatment in Athens and answered that he had. When shown David Caul’s letter, she agreed that it set out the minimum basic requirements. Her testimony thus supported the treatment approach in place at Athens, though the evidence does not specify which individual recommendations in the letter she endorsed.

After Karolin, Harding, and Turner were dismissed as witnesses, they were permitted to remain in the courtroom as observers. Later, on December 10, 1979, the court found Milligan mentally ill, identified his condition as multiple personality, and ordered hospitalization at Lima State Hospital for treatment consistent with that diagnosis. The order gives institutional consequence to the diagnostic framework Karolin had defended, without establishing that her testimony alone determined the court’s decision.

Role in the Narrative

Karolin appears through professional judgments rather than personal history. The account emphasizes the recurrence of her observations, the independence of her diagnosis, and her distinction between the primary condition and possible additional illnesses. Her testimony also exposes the stakes of clinical classification: the diagnosis was not only a description of Milligan’s condition, but a basis for deciding what treatment he needed and where that treatment would take place.
