Georgia rejects final death row appeal for Troy Davis
The US state of Georgia has rejected a final clemency appeal for Troy Davis on the eve of his execution by lethal injection for the 1989 murder of an off-duty policeman.
The Georgia Board of Pardons and Paroles made its decision after hearing testimony from the victim's family, Davis' supporters and prosecutors.
The 42 year old was sentenced in 1991 for killing Mark MacPhail but most of the witnesses have since changed their testimony.
