In an August 2010 decision, the conviction was upheld. The court described defense efforts to upset the conviction as "largely smoke and mirrors" and found that several of the proffered affidavits were not recantations at all. Subsequent appeals, including to the Supreme Court, were rejected, and a fourth execution date was set for September 21, 2011. Nearly one million people signed petitions urging the Georgia Board of Pardons and Paroles to grant clemency. The Board denied clemency and, on September 21, it refused to reconsider its decision. After a last minute appeal to the United States Supreme Court was denied, the sentence was carried out through lethal injection on September 21, 2011.
