A Missouri man is scheduled to be executed on Tuesday, even though the prosecutor’s office that secured his murder conviction 21 years ago has expressed doubts about the integrity of the case.
The US Supreme Court, the last body that could have halted the execution, declined to intervene in the case on Tuesday.
Marcellus Williams, 55, was expected to be put to death by lethal injection at 6 p.m. (2300 GMT) at a prison in Bonne Terre, a day after both Missouri Governor Mike Parson and the state’s highest court also rejected his last-ditch bids to avoid execution.
Williams was found guilty in 2003 of killing Felicia “Lisha” Gayle, a former newspaper reporter who was stabbed to death in her home, though he has maintained his innocence.
St. Louis County prosecuting attorney Wesley Bell, whose office handled the original prosecution, has sought to block the execution due to questions about the original trial.
“Even for those who disagree on the death penalty, when there is a shadow of a doubt of any defendant’s guilt, the irreversible punishment of execution should not be an option,” Bell said in a statement.
In court papers, Bell questioned the reliability of the two main trial witnesses, concluded that prosecutors improperly excluded Black jurors on the basis of race and noted that new testing found no trace of Williams’ DNA on the murder weapon.
Subsequent tests revealed DNA on the knife from a prosecutor and an investigator who worked on the case and handled the weapon without gloves.
The contamination of the knife led prosecutors and Williams’ attorneys to reach an agreement in August calling for him to enter a no-contest plea and receive a sentence of life in prison. (Reuters)
