Roy Michael Roberts

Roy Michael "Hog" Roberts 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. 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.
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 being at the scene. Jackson and five other prison guards were attacked by a mob of 30 inmates, including Roberts. Roberts admitted to punching a guard during the melee, but denied any role in Jackson's murder.
