The execution came despite one of the prosecutors in the case saying that Williams' life should be spared because DNA did not connect him to the case. Critics are calling the execution murder.
Missouri executed Marcellus "Khaliifah" Williams on Tuesday in the 1998 killing of a former newspaper reporter despite a prosecutor in the case and the family of the victim saying his life should be spared.
Williams, who always maintained his innocence − a claim backed by not only his defense team but later prosecutors − is now the third inmate executed in Missouri this year and the 15th in the nation. He was pronounced dead at 6:10 p.m. following the lethal injection, the Missouri Department of Corrections reported.
