Missouri executes Marcellus Williams despite prosecutors’ push to overturn conviction

Williams long maintained his innocence and the killing was opposed by victim's family, jurors and office that tried him

Missouri executed a man on death row on Tuesday, despite objections from prosecutors who sought to have his conviction overturned and have supported his claims of innocence.

Marcellus Khaliifah" Williams, 55, was killed by lethal injection, ending a legal battle that has sparked widespread outrage as the office that originally tried the case suggested he was wrongfully convicted.
