Marcellus Williams, whose murder conviction was questioned by a prosecutor, died by lethal injection September 24, 2024 in Missouri after the US Supreme Court denied a stay. Williams’ attorneys had filed a flurry of appeal efforts based on what they described as new evidence – including alleged bias in jury selection and contamination of the murder weapon prior to trial. The victim’s family had asked the inmate be spared death. The St. Louis Prosecuting Attorney’s Office, which handled the trial against Williams, argued in the motion that DNA testing of the knife used in the killing might suggest Williams was not Gayle’s killer. Missouri executed Marcellus Williams despite prosecutors and the victim’s family asking that he be spared.
