Marcellus Williams, a 55-year-old inmate in Missouri, is appealing to the Supreme Court as he faces an execution date set for September 24. Williams has consistently maintained his innocence in the case that led to his conviction. In a dramatic turn of events in 2017, he narrowly escaped execution at the last moment. His legal team is now urging the Supreme Court to review his case, hoping to prevent the impending execution and to further investigate the claims of his innocence.
