Missouri death row inmate Marcellus Williams' final eight-word statement is revealed as he is executed

Missouri death row inmate Marcellus Williams was executed Tuesday night following a lengthy court battle, during which even prosecutors expressed doubts about his case.

The 55-year-old was injected with a fatal dose of pentobarbital at the Eastern Reception, Diagnostic and Correctional Center in Bonne Terre just after 6pm, and was pronounced dead by 6.10, Fox 2 reports. 

Reporters on the scene said Williams was covered from head to toe in a white sheet and appeared to wiggle his feet and move his head. His chest then heaved about a half dozen times before it stopped, they said, noting Williams did not appear to struggle. 

He had earlier received a final meal of chicken wings and tater tots, and released an eight-word final statement: 'All Praise Be To Allah In Every Situation!!!'

Williams had been on death row since he was convicted in 2001 of murdering Felicia 'Lisha' Gayle, a newspaper reporter who was found stabbed to death in her home in 1998.

He has since appealed his conviction multiple times, as his defense attorneys argued he did not receive a fair trial.

Former Missouri Gov. Eric Greitens even halted his execution indefinitely and formed a board of former judges to review the case and to determine whether Williams should be granted clemency.

It investigated Williams' case for the next six years, but was abruptly shut down under current Gov. Michael Parson, who scheduled Williams' execution.
