Chuck Lee Mathenia, who was scheduled to be executed on 4 June 1993, was granted a 60-day stay of execution by Governor Carnahan on the recommendation of the Missouri Board of Pardons and Paroles, to allow his attorney to prepare a clemency petition on the grounds of reduced mental competence. Chuck Lee Mathenia has a well documented history of mental health problems, but at his trial he was represented by an attorney who spent little time in the preparation of his case, and failed to present any mitigating evidence relating to his medical history.
