On May 24, 1971, Hatcher was sent to trial and pleaded not guilty by reason of insanity. He was sent to a different hospital for more evaluations, where it was determined that he was unfit to stand trial. On June 2, Hatcher escaped from the hospital. He was caught a week later in Colusa, California and arrested for suspected auto theft under the name Richard Lee Grady. Hatcher was returned to the California State Hospital for a mental evaluation. In April 1972, hospital staff determined that his treatment was unsuccessful and that he was a danger to other patients, after which he was sent to the prison state hospital in Vacaville.
