Marcellus Williams was executed by lethal injection in Missouri on September 24, 2023, after the U.S. Supreme Court denied multiple appeals and the governor declined to grant clemency. The execution followed a wave of protests and pleas from the victim's family, prosecutors, and supporters, all expressing their belief that Williams may be innocent. His conviction was rooted in a 1998 murder case, and despite claims of racial bias and questions surrounding the evidence, the Missouri Supreme Court and the state’s Governor rejected efforts to halt the execution. Advocacy groups, including CAIR, condemned the execution and encouraged public prayer, while many gathered in solidarity with Williams in his final hours.
