For how many years was Roky Erickson institutionalized following his 1969 insanity plea?

Answer

Three years

The choice to plead not guilty by reason of insanity resulted in Roky Erickson being committed to various Texas psychiatric facilities for a period spanning three years. This institutionalization included a confinement at the specific facility known as Rusk State Hospital, which was designated for the criminally insane. The duration of three years represents a significant block of time during which he was subjected to controversial medical interventions that he and others later described in very negative terms, linking this confinement directly to his subsequent fragmented mental state.
