Here are some information about Troy Davis’ case from Wikipedia:

Troy Anthony Davis (born October 9, 1968) was convicted of the August 19, 1989, murder of Savannah, Georgia, police officer Mark MacPhail. In 2009, the U.S. Supreme Court ordered an evidentiary hearing to examine alleged recantations by trial witnesses and determine if Davis could prove his innocence. On August 24, 2010, the conviction was upheld, with the U.S. District Court for the Southern District of Georgia declaring, “Davis is not innocent.”

Davis has been on death row in Georgia since 1991. Throughout his trial and subsequent appeals, Davis has maintained his innocence, saying he was convicted as a result of false identification. Seven of the nine prosecution eyewitnesses who had linked Davis to the killing have recanted their trial testimony, with many stating they were coerced by police. The witness who first implicated Davis and has remained consistent, Sylvester “Redd” Coles, was initially a suspect in the crime. One person said that Coles boasted at a party that he killed an off-duty police officer. Another witness who did not recant his testimony and is not himself a suspect in the murder made an in-court identification of Davis at trial.
In October 2008, Davis filed a second habeas corpus petition in the 11th Circuit Court of Appeals in which he raised a freestanding innocence claim and stated that no court had held a hearing on the exculpatory evidence of recanted testimony. On April 16, 2009, the panel denied Davis’ petition by a 2–1 majority. On August 17, 2009, the U.S. Supreme Court, over the dissenting votes of two justices, ordered a federal district court in Georgia to consider and rule on whether new evidence “that could not have been obtained at the time of trial clearly establishes [Davis’] innocence.”

Davis was given an opportunity to present new evidence at a hearing in Savannah in June 2010, but he put on very little testimony. He did not take the stand in his defense and did not call Coles as a witness. He also did not call some of the other witnesses who had given affidavits on his behalf. Savannah journalist Patrick Rodgers commented, “Although the defense team had been arguing for a hearing like this since they took over the case, … they seemed to be wishing they could have a second chance.”

Amnesty International has taken up Davis’ cause, although they are neutral as to whether Davis is guilty or innocent. The group strongly condemned U.S. courts that refused to examine Davis’ evidence and organized rallies and letter-writing campaigns to persuade the Georgia and federal courts to grant Davis a new trial or an evidentiary hearing. Many prominent politicians and leaders, including former President Jimmy Carter, Al Sharpton, Pope Benedict XVI, Nobel laureate Archbishop Desmond Tutu, Presidential candidate Bob Barr, and former FBI Director and judge William S. Sessions have called upon the courts to grant Davis a new trial or evidentiary hearing.
