Now, nearly 30 years later, Alabama is preparing to execute the man convicted in Vance's killing, Walter Leroy Moody Jr. of Rex, Georgia. In Moody's case, the bomb was manufactured in a way that led back to its maker, he said. After Vance's death, officials retrieved an intact bomb from the courthouse that housed 11th Circuit judges in Atlanta. That tidbit led investigators to Moody, who had been convicted in a 1972 case involving a bomb with flat, welded end pieces. A federal defender has asked a federal court to block the execution, arguing the state can't execute Moody because he's technically in federal custody.
