County prosecutors and defense lawyers both claim that mishandled evidence and racial bias tainted the murder case. Marcellus Williams is slated for execution Sept. 24 at 6 p.m. CT.

The execution of Marcellus Williams will proceed today, the Missouri Supreme Court ruled in a decision rejecting efforts to show a potential juror in his murder trial was excluded based on race.

Williams is set to be executed Tuesday for the 1998 killing of Felicia Gayle, a crime that he has always denied any role in. His attorneys have launched multiple legal battles in an attempt to save his life.

Despite efforts to spare the life of Marcellus Williams, Governor Mike Parsons on Monday denied clemency for Williams, setting his execution for Tuesday at 6 pm for the 1998 murder of Felicia Gayle, in St.

Marcellus Williams was facing what may be his last 48 hours of existence, a crucial period with court cases to spare his life currently underway at both the Missouri and U.S. Supreme Courts.

Marcellus Williams' lawyers urge the Missouri Supreme Court to stay the execution scheduled for Tuesday, Sept. 24, amid new DNA evidence suggesting innocence.

Marcellus Williams' lawyer focused on what he said was a prosecutor's admission that he illegally struck at least one juror because of his race in the original trial.

Attorneys for Marcellus Williams said if his execution proceeds, it will be the first time in Missouri that an execution has been opposed by the prosecutor and the victim’s family.
