FILE-In this Friday, Feb. 15, 2008 file photo shows Kennedy Brewer, right, hugged by a friend, moments after a circuit court judge exonerated him for the kidnapping and murder of a 3-year-old girl in Macon, Miss. Convicted in 1995 of raping and killing his girlfriend's 3-year-old daughter and sentenced to death. In 2001, DNA testing proved that Brewer was innocent. Since 2000, at least 18 men convicted in rapes and murders largely because of bite-mark analysis have been exonerated by DNA testing or otherwise proved not guilty. (AP Photo/Rogelio V. Solis, File)
