Marcellus Williams, the Missouri death row inmate who has maintained his innocence for nearly 24 years, is scheduled to be executed Tuesday, a day after the governor and the state Supreme Court refused to intervene.

Missouri is set Tuesday to execute Marcellus Williams, a death row inmate whose case has spurred several efforts to save his life amid doubts about the evidence presented at his 2001 murder trial and the actions of a trial lawyer in the case.

Hope lingers for Missouri death row inmate Marcellus Williams who was convicted of the 1998 murder of local news reporter Lisa Gayle despite lack of forensics linking him to the crime.

The Missouri Supreme Court and Gov. Mike Parson have declined to halt Tuesday’s execution of a death row inmate prosecutors say may be innocent, leaving his fate in the hands of the US Supreme Court with less than 24 hours to go before he is scheduled to die by lethal injection.
