On September 21, death row prisoner in the state of Georgia, Troy Davis, was killed by lethal injection. His execution came despite a campaign from around the world in his defence, including by Amnesty International, and protests outside the prison where he was held and across the US. Last-minute legal appeals in the US Supreme Court failed to stop the execution.
Davis was found guilty of the murder of police officer Mark MacPhail in 1989 and sentenced to death.
