Missouri is set to execute 55-year-old death row inmate Marcellus Williams on Tuesday evening — despite pleas from prosecutors and even his victim’s family. Missouri’s governor, Mike Parson, and its supreme court said Monday that sufficient evidence exists for the state to take Williams’ life for the 1998 stabbing murder of Felicia Gayle,

"No jury nor court, including at the trial, appellate, and Supreme Court levels, have ever found merit in Mr. Williams' innocence claims," said Missouri Governor Mike Parson.

A Missouri man seeking to avoid execution suffered dual setbacks as the state’s top court and governor each rejected requests to cancel his scheduled lethal injection on Tuesday.
