One of the most hotly contested death row cases in recent years looks set to go ahead with the execution of Troy Davis in Georgia on Wednesday.
Davis lost his final bid for clemency despite overwhelming evidence indicating that his conviction for murder is unreliable.
He will be put on a gurney at the state prison in Jackson and administered a cocktail of lethal drugs at 7pm local time on Wednesday, barring a last-minute intervention by the US supreme court which few observers expect to take place.
