Troy Davis was convicted in 1991 of the murder of 27-year-old Officer Mark Allen MacPhail, white, who was shot and killed in the car park of a Burger King restaurant in Savannah, Georgia, in the early hours of 19 August 1989. Davis was also convicted of assaulting Larry Young, a homeless man, who was accosted immediately before Officer MacPhail was shot.
At the trial, Troy Davis admitted that he had been at the scene of the shooting, but claimed that he had neither assaulted Larry Young nor shot Officer MacPhail. There was no physical evidence against Troy Davis and the weapon used in the crime was never found. The case against him consisted entirely of witness testimony. In affidavits signed over the years since the trial, a majority of the state’s witnesses have recanted or contradicted their testimony. In addition, there is post-trial testimony implicating another man, Sylvester Coles, as the gunman.
In March 2008, the Chief Justice of the Georgia Supreme Court, joined by two other Justices on the Court, wrote that,:
"In this case, nearly every witness who identified Davis as the shooter at trial has now disclaimed his or her ability to do so reliably. Three persons have stated that Sylvester Coles confessed to being the shooter. Two witnesses have stated that Sylvester Coles, contrary to his trial testimony, possessed a handgun immediately after the murder. Another witness has provided a description of the crimes that might indicate that Sylvester Coles was the shooter."
