Roy Michael Roberts

Roy Michael "Hog" Roberts (December 18, 1952 – March 10, 1999) was an American murderer. He was executed in Missouri by lethal injection at the Potosi Correctional Center, for assisting the murder of a correctional officer named Tom Jackson in Missouri's Moberly Correctional Center in July 1983. Jackson and five other prison guards were attacked by a mob of 30 inmates during a prison riot. At the time of the murder, Roberts, who had six prior felony convictions was serving an 18-year sentence for two counts of first degree robbery and a theft conviction. The robberies had involved the use of violence.

Roberts was convicted of capital murder for having held Jackson and punching another guard who tried to intervene, thus allowing fellow inmates to murder him.

Robert's final statement was, "You're killing an innocent man and you all can kiss my ass."

A 2005 investigation was opened to investigate the possibility of Roberts' innocence. No physical evidence connected Roberts to the crime. Four eyewitnesses, including three corrections officers, testified that Roberts had participated in the murder, while nine witnesses, including another corrections officer, had testified that Roberts had been elsewhere at the moment of the stabbing. Roberts himself admitted to participating in the riot and punching a prison guard, but denied any role in Jackson's murder.
